Side by Side Comparison of: Aosom vs AW

tops out at 28mph.

So far so good! I got this entire kit for $219 on Amazon with $15 for shipping! The motor is strong thus far and was a cinch to wire to the controller and battery. The instructions, although filled with grammatical errors, were detailed and of a high quality. The rack is actually pretty hardy, all be it a bit heavy and the bag is decent but definitely not for the long term. The controller has been able to handle peak voltage of 50v with at least a 21 amp draw and the motor hardly heats up. I am currently running a 13s LifePo battery built from used hybrid car battery cells. I ended up cutting the end off of the charger (it had a computer cord) and put some temporary bullet connectors on there to hook up to the battery. The charger will charge up to 55.2v at 4.5 amps, but I still monitor it to make sure it won't destroy the battery and set it on fire. The rim, tire, and tube are all of a decent quality and the spoke gauge is something like a moped would have. So far I am very happy with this purchase.

Amazing kit. Amazing customer service. 35mph top speed. Can't be beat for the price. Aosom has the most outstanding custom service I've experienced.

Buy without any hesitation - Aosom people are the best in customer service I have experienced on Amazon.I had a couple of problems with the kit long after I bought it but they send me new parts free of charge. I received it in 5 days after contacting them.Easy, fast, and very friendly customer service! They will fix any problem you have with the kit.The kit itself is a great - buy a 20AH Lifepo4 battery and you have a motorcycle!

I got a Wal Mart bike to do my conversion. I wired 4 12 volt 10 amp hour SLA batteries in series using 12 gauge wire. I put in a 30 amp blade type fuse. I had to carefully file the rear drop outs from 10 mm for the axle to fit. I then installed a Grinn torque arm for extra sturdiness to keep the torque from spinning the axle out. I weigh 250 pounds with 25 pounds of SLA batteries. With no pedaling on flat road I got 25 mph with this kit. Have not tried range yet but will be doing that next. I got the SLA batteries for the cost just to make sure this would work and it seems to be working fine. I plan on getting a Lithium battery pack next. I worked a little each day on this over about a 2 week period to make sure I did it right the first time. For the first run of this everything is working as it should. This bike has V brakes and while it will stop you at 25 mph, you need to give yourself at least twice the stopping distance as opposed to having a bike with disc brakes.UPDATE:I had a wheel bearing go bad in the hub after I had it for 6 weeks on the bike. I emailed Aosom and they sent out a new hub motor/wheel and I had it in 2 days. They did not ask for the old one back either. This company has the best customer service I have ever seen. So, if you are having doubts, go ahead and get this kit and if you have any problems, Aosom takes care of it fast. FIVE STARS!!!

This is my first kit for an electric bike, and the kit exceeded all my expectations. I did not intend to get this kit to replace pedaling on my bike, but rather as an electric assist. I take my kids on a burley, and this make that a breeze. This can even take me and my 1 year old and 4 year old up the hill.I would say that slightly pedaling and using the motor, it will take me a little above 20 miles in one charge, and when I say slightly pedaling, I mean I won't even break a sweat. I estimate I would probably get about 14 miles with no pedaling. There are no significant hills where I live. I use 4 12ah 12v batteries in series to make a 48v 12ah battery. I can only imagine what a 48v 20ah battery would be like!I have no way to measure how fast I am going, but when I ride next to a road that has 40 mph speed limit, it seems the cars a going slightly faster than I am (When I'm riding by myself at full throttle), so I'm going to guess that I'm going around 30 mph. Again, I don't have a way to verify this, but it goes plenty fast.Overall, I love this motor and I would recommend it.

Amazing and easy kit. I used 4- 12 volt 9ah batteries made by ExpertPower on amazon. They cost $75 for all 4 and work great with the kit. I can go 10-20miles depending on my speed and terrain. The lcd screen it comes with is good too, and shows milage, speed, and the voltage. Voltage is very helpful to know when battery power gets low

Love this kit. Installed the basic wheel and throttle in about 1 hour. Pedal assist is option (not required in U.S.) so the sensor does not need to be installed. The included brake handles are also optional, but their benefit is that they automatically disconnect the motor when a handle is pulled.I am 6'1" tall and around 200 pounds, On an inexpensive cruiser bicycle and at full throttle, this motor comfortably gets up to about 30mph.For the batteries, ordered 4 of these when they were on sale: http://www.amazon.com/Battery-Tender-BTL24A360C-Lithium-Phosphate/dp/B00F9LPKJ6?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage Placed the four batteries into a $10 plastic toolbox and connected them together using 12ga wire, then to the motor using Anderson Powerpole connectors.Strapped the controller and toolbox on the bike rack over the rear wheel. My battery configuration lasts about 10 miles with lots of throttle and very little pedaling. Will buy again.Having put 500+ miles on the wheel, an update is in order. The wheel has continued to work fine and I try to commute on it once a week. The motor has been working fine without issue. Some things I notice:1) the motor has very little torq from a complete stop. Best to push off and start pedaling to help it get up to speed without burning a lot of battery energy. Once started moving, the motor has plenty of energy to help a sustained pedaling with little drain from the batteries.2) The main power wires are connected to the controller using a small, yellow terminal block. Hiding that block on the bicycle is not easy if you want to be able to quickly remove the wheel. A plug would be much more convenient, but I have not tried one.3) the wiring harness is not adjustable for length. Unless you are capable of installing like connecting ends on the cables, the excess wire must be wrapped up and hidden somewhere. Getting the cables back to the rear wheel and controller from the handlebars can look ugly, but I have found that using a piece of aluminum rod (perhaps Small Parts 14305 Threaded Rod 1/4"-20 - 3', Aluminum 6061 or smaller) you can bend it to the shape of your frame and wrap the cables to it tightly using the cable wrap that comes with the kit. Once the rod and cables are then attached to the bicycle, it looks orderly, like it was designed to be there.4) with batteries installed, the bicycle is too heavy for most trunk mounted racks. Even after removing the batteries from the bicycle, I recommend a trailer hitch and to use a hitch rack. Since the rear wheel makes the bicycle so backheavy, it does not "hang" well on racks with arms. I ended up making my own rack which allows the bicycle rear wheel and front fork to rest on a platform instead of hanging on hooks.5) batteries that I use to run the wheel. I have two Lithium Ion 48v 20ah batteries on my bicycle. I have ridden 20 miles on a single battery when comfortably pedaling along at about 20mph and still have a little charge left when I get home. After most 10-mile trips, it takes about 3 hours to charge a battery.6) I did not install the pedal assist and the unit works fine without a pedal assist cable being plugged into the controller.7) I did not install the disconnecting brake levers since I use hydraulic brakes Shimano SLX M675 Mountain Bike Disc Brake. You just have to be mindful of releasing the throttle when applying the brakes. Newbies may want to install the disconnect brake levers for peace of mind.8) motor has subsequently been re-laced into a 57mm single wall rim and is now running with a Duro 3" tire. the first 26x3 inch tire was a Sunlite Cruiser Flame Tires, 26"x 3.0", Black/Black but I did not check air pressure when I picked the wheel up and about a week later on a particularly hot day, had a blowout in the sidewall. The Duro is kept at about 20 lbs pressure and works fine, especially on wet, grassy field and has been working for a year now without incident. The way I had the wired routed from the wheel to the controller, it would take some tools to place the tire, so a repair could not be done on the road.9) the wiring is not waterproof, but it can be protected a lot with careful placement of connectors. I have not ridden in heavy rain, but it has done well in mist and light sprinkles.10) the tire that comes with the wheel is pretty flimsy. I found that the original rim worked best for commuting with this tire: Schwinn Cruiser Bike Tire with Kevlar (Black, 26 x 2.12-Inch)I think that is everything I have learned using this product. Since then, I have purchased two more of this model from this seller.

Installed this on my vintage 1985 stumpjumper sport bike which is already heavy. The batteries are SLA's and they do weigh 40 lbs. Now the bike weighs 81 lbs. total and I weigh 265 lbs. This motor can pull hard. 7 seconds on half throttle is already 25 mph according to a GPS speedometer.
I don't plan to upgrade to a LiPo battery since the heavy lead acid batteries are sufficient. I mounted and glued these batteries on a plastic clipboard to keep them in place. They fit nicely on the supplied bag for a rear bike rack with room to spare.The supplied tires is at its max psi (50 psi) but the rim easily hits the ground even on a slight bump. Suspension is a must for a heavy setup with Lead Acid batteries + the heavy rider otherwise you end up slowly destroying your bike.

Was a little skeptical about kit but it's great so far have about 50 miles on it longest ride was 6 miles at 3/4 throttle 27 mph the whole way used about half charge top speed is about 32 mph. Put kit on kona full suspension mt bike goes on and off road up steep hills with some peddling it can go 17 mph easily.wired 4 agm motorcycle batteries trs9bs chrome batteries about 6.5lbs a piece so bank is heavy but inexpensive and lots of power about twice the weight of lithium ion but 6th the price and recyclable. Kit hooked right up have an open mind .charge it with 48 v 3 amp charger from battery mart .

Very pleased with kit. Did require some filing on the frame dropouts (where the axel goes mounts to the frame) to get the axel to fully seat. Took me about 4hrs to do the conversion, but I shortened wires and used bullet connectors to make the installation nice and efficient. I weigh 230lbs and the bike can take me 4.1miles to work and back with just under 2.1amp-hours of battery use and nothing gets hot. This includes some short sprints of ~24mph on a flat surface. Was pleased enough to buy a 2nd one. Recommend getting the twist grip throttle rather than thumb throttle as your thumb will get tired if you intend to bike long durations (no throttle lock). Had two complaints. You really need a bike that has a rear disc brake and full suspension. This is difficult to find at Walmart/Academy for donor bikes to find a frame that will fit the rear disc brake. Rear dropouts need to be beefy if you use an aluminum bike frame or you need the torque arms. This thing puts out some serious power and you run the risk of ripping out the axel from the dropouts. Also, the spokes are "squeaky". We carry most of the battery etc on the rear wheel and as such it has a fair amount of weight. Some spokes were not tight and would work or be squeaky.jl

Only giving it four stars because in the end it really works great, but I only got it to work because I am and engineer, had perseverance and the ability to kind of figured it out as I went. You are literally better off, NOT following the instructions included, they are that bad. It's a shame because the actual product is really good.Kit comes with EVERYTHING you need including the charger.

does anyone know a lithium ion battery that will work

I'm very impressed with this kit. From what I can tell its very solid, well put together, and even looks pretty good on the bike. It was also very easy to assemble. Everything is color coded and the different plugs designed specifically to fit into eachother so you don't mistakenly plug the wrong ones into one another. In fact for someone as mechanically inept as me I'm surprised it was so easy.The amount of power this thing has is impressive. Had no problem going up and down the hills in my area, which was a worry when I bought it. Also holds a charge pretty long. Honestly its sold with an assist option, but I never installed it. The kit and batteries add a lot of weight to the bike, and its a bit impractical to peddle it except if you're faced with a steep hill and don't want to burn out the engine.Just a warning though, this kit and the batteries needed for it add a LOT of weight to the bike. If fact I felt unsafe riding it with everything mounted on the rear rack, so I jerry rigged it a bit and mounted the batteries in the center of the frame on a plate meant for a gas engine. And that felt a lot more solid and balanced. That being said, the rear rack and bag included are both very solid and well made, and I understand its easier for most bicycle owners to mount the parts on a rack rather than do what I did and desperately look for an engine plate. So its nice the company included them. Also, you'll want to invest in a better stand for your bike because I guarantee the one it came with will not hold it up. I've just been leaning mine up against things, but I'll be buying a two legged stand soon.My biggest complaint is that this company doesn't also sell the batteries or link you to a compatible set. In fact that turned out to be the biggest challenge in putting this bike together, because I had no idea how to wire up batteries. I did get lucky and found a set with the right voltage that somebody had already wired up, but I still had to install the plugs connecting the batteries to the engine myself. The task itself wasn't hard, but finding the right plugs was a pain. That's the only reason I bumped the rating to four stars.

The kit is awesome! I weigh 160 and with 4 SLA batteries I get 35 on the flats no problem at all!!!! The only con is awkwardness at slow speed due to my batteries on the back rack and the spokes come loose so make sure you tighten those up before putting onto your bike. Had it for 2 months now and is holding up so far. Using mighty max 12v sla in series and they are holding up too! Conclusion: A TON of power for your $$$$!!!!!

Everything arrived within a week of ordering . A very powerful package for your bicycle at a good price . The instructions need better English but can be figured out .

The instructions are pathetic and the charger connector is strange. I cut off this connector and replaced with crimped/soldered high amp polarized automotive connectors so that the battery pack can connect to both the charger and controller. The blue wire on the charger is positive. I mounted 4 SLA 12AH batteries in the middle of the bike frame for both stability and better weight balance. The batteries are wired in series with 10G wire with spade connectors that are both crimped and soldered. The rack fit on my older Trek mountain bike ok and supports saddle bags and rear tail light. The controller is rubber foam shock mounted under the seat in front of the rack. Once installed, this thing really works good. I'm giving it 4 stars because the seller refused to honor a 30 day price guarantee that is common on Amazon. They lowered the price by $40 within 30 days of my purchase, claiming that they only have a 7 day guarantee. Also the bad instructions and connector issues. Why can't some basic coherent instructions be provided by someone whose first language is English?

Translated instructions are almost indecipherable, but the installation is pretty common sense if you can reference pictures.
Contains a handful of parts that may or may not be applicable to your bike, such as a disk brake and European-required pedal assist sensor.
The zip up bag included to house the control hub is a joke, get some panniers to house it and your batteries.
Would love to know if the speedometer can be changed to MPH instead of KPH, but that's certainly not a deal breaker. Also I know there's a backlight in the monitor, but I can't figure out how to turn that on.

Don't buy this kit for the brakes! You need good brakes for 30mph or even for 25mph I am using regular good older type Tektro brakes! I'm running 20AH Lithium Polymer 12s so about 52v I want to try 15s but not sure if controller and screen can take it! The wires are a little skinny and I plan to replace in the future.
The Chinese Instructions are horrible! you need to know what you are doing or you can get hurt on this going 25-30 mph I recommend the rear kit as most front forks cannot take 1.5HP and be careful on aluminum rear dropouts! I am using this on a Cannondale Super V and its is nice so far but a car pulled in front of me and I had to lock up brakes and skid to a stop! Almost fell
I would not put this kit on a non suspension bike! Full suspension and I'm good to go but in a populated area with soso roads I'm gtg with full suspension. Also you will need to get the rim spokes tightened! I will update after more usage so far about 50 miles on it.

4 stars. DON'T use the yellow thing is my suggestion. Find another way to connect the blue, green, and yellow jacks together. I blew up a brand new $600 battery, and I think this is why. I had another 48v kit that had regular connectors for the blue, green, and yellow wires and it ran fine (but it sparked because I wasnt using LI-ION packs with power switches).

I would suggest getting basic connectors for the yellow, blue, and green jacks and see what you can do. If you can figure out switches for the power to the battery, I think you have won the war, I still have to read into this stuff and it's sad because I've been riding the LEEDs 24v kit for months now, and I want to use this one which is faster... oh well, we'll see what saving up some $$$ does for my next battery.

Last note: Schwinn road bikes are THE LIGHTEST and best bike to use with these kits. I know this from trying several aluminum frame mountain bikes. You might need to order special brackets for disc brakes, but it's worth it, these road bikes are great, schwinn chains don't rust, and I have used their bikes for decades with no problems. Just a suggestion.

Took me 4 hours to install. I bought V Power 10 amp 48v battery. Installed on Genesis dual suspension bike. Battery bag is on seat rack with two folding wire rack baskets for cargo. Top speed 32 MPH. 10 amp battery gets me about 15 miles with no peddling. My fried bought recommended 20 amp Vpower battery. He gets about 30 miles range. The larger battery accelerates faster than the 10 amp. My initial controller had a glitch. Contacted seller and replacement arrived today at no charge. Good company to buy from. Service makes a difference when most components are Chinese and available from a variety of sources.. Will recommend to my friends

Very good electric motor. I use at 50v 20ah battery for this kit. I enjoy cruising around the park and neighborhood on weekends. I also commute to work using this kit. The fastest you can go on level ground is 32mph with this 1000w motor. It will accelerate to 32mph quickly. When I use it at 32mph, the battery will die in around 30-40mins but I usually cruise at 20mph when going to work anyway. The highest speed recorded was 42mph but that was when I was going downhill. The speedometer and odometer have lag on it. It doesn't start counting the distance immediately but that doesn't matter to me. It has very good torque. The throttle is very sensitive. This bike will get you going fast. I weigh 180lbs when wearing my backpack with my college textbooks, laptop, and water bottles. I'm unsure how the motor will respond if you weigh over 200+lbs. This conversion kit fit right onto my Giant Warp DS2 perfectly. Easy and perfect installation. I gave it a 4/5 instead of 5/5 because of one issue. The only issue i've experienced with this kit is that the motor will randomly shut off while I am riding sometimes and I have to turn it on again. I've checked my battery connections and they are secure so it was must have to do with the motor/controller. This does not happen often(only 1 time this month, 2 times last month). This could be dangerous if you are riding in traffic and the motor cuts off at the wrong place at the wrong time.

I received this comprehensive conversion package. Good power 1000W and looked sturdy. Unfortunately, the assembly instructions were too basic and the battery and charger that was recommended were not compatible. Way over my head to make it work with what was recommended. I had to return the entire package because the correct battery plus the conversion kit were more expensive than my budget. Please do not assume that the recommended items are accurate. In this case, they were way off. Good luck. I am now planning on purchasing a fully assembled ebike once my budget is inline with that.

Had to change my review from 4 stars to 3. Here's why:1: instructions show installation of disc brake. This does NOT come with a disc brake. Had to do some major adjustments of my caliper brakes for now, but trust me when I say that it NEEDS a disc, if for nothing more than the weight.2. The bag for the controller is a nice bag, but not a lot of thought went into it. It doesn't hold its shape, so if winds up sagging to one side or another, and the less said about how it's supposed to attach to the rear rack, the better. I'm having to reinforce it with two lengths of 2x3 and bolt it down onto the rack with some through-drilled 1/4" x 2" stainless bolts so that it stays put and stays in form.3. No mounting hardware or instructions included for the rack, which is a shame because it appears to be a good-quality, heavy-duty rack. Fortunately, I already have a rack installed, but am keeping this one for a backup, just in case.4. The instructions are a complete joke. Good luck deciphering them if you're not someone who's both mechanically-inclined and know your way around electrical wiring. There was absolutely NO mention of the terminal block assembly, for example - I had to figure this one out on my own by looking at the wires from the motor and then realizing that there were matching wires on the control unit.5. My batteries weren't adequate at first, so I've been pedaling it for now. The sprocket/gearing cassette makes an occasional "bumping" noise, but no loss in pedaling ability, and truth be known, it rolls better than the wheel and cassette that came with the bike! But what concerns me is this drag/scratch sound that occurs while I'm rolling. Oddly, it only happens when I'm on the bike, adding my weight to it, and not while I'm just walking it.6. The grips that are included are flimsy and appear only to be provided because they're embossed with the company logo. I'm going to replace them with some better grips that actually give me a good purchase on the bars.Now...the good...After staring at it for awhile, I was able to install everything in under 2 hours. Then again, I've been working with wiring and mechanical parts for the better part of my life.It rolls freely once properly aligned, and exceeded my expectations in normal pedaling.We'll see how things go once I get the proper batteries hooked up...which, with luck, will be later today. I'll edit as needed.

You need to have at least some experience using tools and hooking up batteries. If you don't, you'll need some help putting it together.my product was defective but the customer service team fixed my issue.

Is there an instuction video about the wiring? I just bought this kit and am kinda confused on the wiring,,,dont want to burn it up before i use it,,,

Instructions are rather vague. The charger is very cheap (quality).However it does work.

Comes with no instructions and battery bag is flimsy.

The product was really nice for my first kit but the spokes are all either broke or lose within my first month of riding and now about to seek my options... check your spokes since I trusted mine as was when I got mine

Kit motor is relatively acceptable, but the other components are very cheaply made. the wiring is plain badly done, and the LCD display is very susceptible to water. the motor can have dead spots in it due to a bad winding, and this is why many people have had theirs "stall" the wheel is double walled however, which is a welcome improvement. still, a few improvements that are very key keep this kit from being anything but "meh" at best.

I put this on a mountain bike. I used the rack for a while, but it's not worth the hassle. It only took a couple of rainy trips for it to rust and not much longer for it to snap. Buy a heavy duty rack with this. Really basic instructions. After a month I had an issue with wires starting to come loose from the plastic and I have to fix them every once and awhile. I also found that the sla batteries weren't adequate and had to replace them (I didn't put much thought into it and bought from the "frequently bought with" section). If you get sla batteries you MUST make sure that they are for cyclical applications. It can be hard to avoid total discharge, so get batteries that can deal with that. Avoid big bumps because I had the spokes come loose pretty bad and had to have a shop fix them and the tube they popped. Pad brakes don't seem to get a good grip on the sides of the wheel.Because I had a hard time with this I ended up spending as much as it would have cost to buy a low end premade ebike, which I wish I would have done. I don't think I would have had near as many problems with a premade.

Kit is great. Goes fast. Easy to install. But, the wheel ran backwards. I'm sure there some sort of wiring issue I couldn't figure out and probably a was to resolve easily. But I couldn't figure it out. I ended up taking off the gears, flipping wheel around, and losing my pedal chain, which was ok because I didn't want to pedal anyway. It's a cool electric ebike but it's tricky if you don't know a lot about electronics.

Putting it together was pretty straight forward. I've had this on my bike for a couple weeks and the throttle has a slower response time and the controller got so hot it melted a few chords together.

Poor instructions, No support from selling company and no response from an e-mail sent to manufacturer

Terrible

First off, the electrical harness included in this kit is somewhat incomplete and I would not recommend this to a beginner. I have, however, experience in putting together electric bikes and could complete the wiring with parts I had in the shop. What is disappointing is that after a few months of use, the freehub broke. This means that the chain can move the cassette (rear sprocket) freely, in both directions, without engaging any drive in the wheel. So what I have is a motorized scooter with the added aesthetics of a chain and pedals. I cannot recommend this motor. I would go with the http://www.amazon.com/gp/product/8805001546?psc=1&redirect=true&ref_=oh_aui_search_detailpage motor instead. The wiring harness is complete, and there are fewer parts to fail.

I ordered this item in August and It took several weeks to receive my item. Once it finally I arrived I inspected it to find that not all the parts indicated on the description/manual were included. I spent several weeks trying to get the issue resolved through aosom. They gave me the run around for 2 weeks before telling me that the manual/description was misworded and I was SOL. I took it to my local bike shop who is licensed for ebikesBro have it installed. So I finally got it up and running the day before Halloween. I really enjoyed it for about 3 months. I use it to commute to work(2.5mi) so i can keep my black truck out of the Florida sun. On my way back to the office during lunch the motor stops working. I took it to the bike shop(after lance Armstronging it back home). The owner and I start investigating and find that the controller( which was a pain in the but from the beginning). He stated that it was pretty apparent to him that the controller was faulty and defective. Moreover, I could have been seriously hurt via electricity or fire if I hadn't brought it in immediately. I contacted aosom and requested a replacement. They said I was SOL since I was passed 90days from purchase, but they would be more than happy to sell me another defective controller. Aosom excels at Customer disservice. Don't buy any of their crappy products unless your buying a gift for someone that you wish personal harm upon.

absolutely horrible took 5 hours to put together and still not working the instructions are terrible lots of details missing

I purchased this as part of a "Items commonly purchased together" lot on Amazon. So, the batteries and a charger came separate.Full Disclosure: I have practically no electrical experience. I thought this would be as simple as strapping on the rear wheel, connecting some cables, and off I go but that was far from the case. I don't like posting negative reviews but the manual is a joke and has no description nor pictures of how to connect the batteries. The connectors that come from the control unit don't match what was on the batteries, nor did they come with any adapters.The rear rack that comes with the unit was missing a small but integral part which connects the rear rack to the seat post. Otherwise, the rear rack doesn't stay upright. Also, NO descriptions nor pictures showing maybe an alternate way of hooking up the rear rack.I was never able to even get the item working.The only positive spin I can put on this is that the customer service person was polite and prompt in answering my initial grievance, it still doesn't change the fact that they really, REALLY did not want me to return the item. They provided me with a refund just so I would keep the item.So, if you know your way around electrical components and feel confident you can get this working without a manual you really cannot beat the price. Otherwise, I'd recommend steering clear of this.

When I got the kit I was under the impression that all that you need came in the E-bike kit. I was wrong I though it you can use one battery, but for a 26' 48 volts you need 4 BATTERIES. The charger didn't come with the correct terminal so,there you COST GOES UP!. The kit cost me with two batteries $307.00 dollars. They should tell the costumer ALL THAT YOU NEED before baying the kit.Before buying any Kit make sure they tell the total that Cost.to convert a regular bike to a E-BIKE.

Okay now I'm pissed off the wheel is not 26"×1.75" its 26"×2.0 and it didn't come with the disc brake neither did it come with the bag to put the batteries in it only came with a stupid small bag that is useless also in my case it didn't come with a yellow box this is not quality service what a waste of money I was so excited now I'm not

Did not come with disc brake as stated in the description, and shown in the picture of the item. Was disappointed that the product was not as advertised. Will send it back for refund.

It is a great product but unfortunately it didnt last a year. The controller no longer works and now i am stuck with a electric bike that doesnt work.

I put it all together with a 20 ah Lipo battery. Worked ok for a few days and 2 miles then quit completely.. I can get it to go by holding the arrow button down on the down key on the LCD panel but it only goes slow speed. Most likely the motor controller or maybe the LCD not sure and while I would just pay for the parts, I read the controlllers are not available for this model any more so now this means I have to get a controller and do a bunch of wire splicing and hope it works.... or just buy another kit, NOT!! pretty disappointed in all....was fun while it worked for the two miles.
There is no on off switch so when connecting battery maybe the initial voltage spike frys the electrical components in the controller, is what I suspect. Maybe a diode installed in the load line would help cushion all this or maybe a large capacitor.... not sure pretty bummed out all in all.

There are many things wrong with this product. I am unable to tell you if it is even worth it for an expert as I still have not completed the conversion. If it works, then perhaps 3 stars. But, as conversion kit, this is not something you should buy unless you are an expert. First off, the instructions, apart from making no sense, are incomplete. They have pictures, but often the pictures are not of the part in the kit. And they are not pictures of the assembly, but just the parts and someone pointing to where it might go. Then, there are parts that are not described in the instructions. There is a disc brake, no information on that whatsoever. There is a small yellow, what appears to be clamp. Again, no mention of it in the instructions. The instructions refer to a controller mounting bag that was not in the kit. There is no information on how to reconnect the brakes, or if you are to reconnect the gear shift cable, which seems odd since this is now motor driven, but also has the multiple gear sprockets. Not at all what I expected in a conversion kit.
