PEXMOR Electric Bike Conversion Kit, 48V 1000W /1500W 26" Front/Rear Wheel E-Bike Hub Motor Kit, Upgrade 3 Mode Controller w/PAS/LCD Display/Twist Throttle Ebike Bicycle Wheel Kit

Pros:- All the power you should need. I live in a very hilly area and only need to pedal to assist the motor up the very steepest hill (it's a struggle to walk up that one and would be unsafe to sled down).- As simple as a kit like this can get. There are a lot of things that need to be done to safely convert a bike, and I can't think of any step that wasn't already as simple as possible.- Excellent display and controller. Does everything I want, viewable in direct sunlight.- Insanely cheap. For me it was cheaper to buy this kit, a battery, and a bike (if I didn't have one already) than a much lower-spec e-bike premade.- Good build quality. None of the parts feel fragile, and I'm not worried about them failing prematurely.Cons:- Had to widen the dropout on my bike to fit the motor. The rear dropout on my bike was 135mm wide, and I had to widen it to 150mm to fit the wheel. Fortunately my frame is steel, so a few minutes pulling the forks apart (and then re-straightening the dropouts) did the trick.

Best ebike kit ever! Was really easy to setup. Doesnt have instructions to connect battery so if you need to connect the battery, connect the red and red together, cut a bit of the rubber film off, same with the 2 blacks. Use the electric tape. Topped this bike off at 37mph. LOVE IT

If you want to get this product you better have the battery first or have it ordered because it doesn't come with it. now I just have a $250 motor wheel with no way of using it and you better hope and pray the battery you get ACTUALLY works with it or you will have an almost $500 to $700 combined product that WON'T EVEN WORK.. 100% WOULD NOT RECOMMEND!!!!

Put this kit on a cheap Vevor adult tricycle. Takes a bit of mechanical know-how to get it to work but you have all the parts to do it except a battery kit. A few tips I found the hard way:1) as another reviewer noted, the instructions are terrible and don't tell you which direction to install the front wheel kit. As you lay the wheel assembly flat with the wire cable sticking up and the word Pexmor visible, the hub will spin clockwise, so that's the right-hand (starboard) side.2) The kit comes with a torque arm assembly that looks horribly tacky, depends on a thin hose clamp to hold the end of the arm; but I noticed that the hole in the washer end of the kit happened to line up with one on my fork--all I had to do was drill it out slightly and put a bolt in it. Just watch the clearance to the screws in the main hub!3) Someone else pointed out that the throttle was touchy, and they're right. No easy fix, either, maybe somebody has tried a better twist throttle? Reprogramming the throttle ramp in the controller is beyond us ordinary mortals. It is possible to get away from a stop sign at a sane rate but you must have a delicate touch. Someone else said theirs would do burnouts but mine won't on asphalt, just loose dirt.4) I'm thinking I bought too big a battery--I've got 15 miles on the first charge and the battery meter still reads full. I got a 48V20AH LIPO, I think a 10AH battery would still be overkill.5) Instructions again: they say long-press the speed-up button to turn on the headlight BUT DON'T TRY IT! I was standing next to the trike and it nearly ran me over when I did that. The light just comes on when you power the system up with the "M" button.

So far so good , I put 1000 miles on it and no problems so far. Has decent speed and power I get mine to 37 mph on a full battery

It's probably a decent enough conversion kit, qualitywise, but it hasn't been an easy installation. First, the bicycle that I was going to install it on didn't have disc brakes. So, ended up buying a different bicycle WITH disc brakes. Then, the disc brake's caliper was too thick and rubbed on the wheel, so I had to purchase a thinner caliper. Then, all of the controls that go in the bag and strap under the cross bar wouldn't fit because the new bicycle has a monoshock there. So I have the bag of controls kind of ziptied off to the side. Then, the PAS module is supposed to go between the pedal and the crank. I purchased the crank removal tool but it stripped out the aluminum threads on the bicycle. Now, there isn't any pedal assist, and also there's a vibration in the wheel or motor when operating it. Also, be aware that with a front wheel conversion, it will make the front wheel spin in certain uphill situations, when you don't have enough traction or weight over the front wheel.

Everything came well-packaged. The assembly was relatively easy, and I was happy to see everything looked okay at first glance. But after having the system assembled I noticed there was some faulty wiring with the controller box.I bought a Bafang headlight and hooked it up to the headlight wires (hold the down button to turn headlight on/off) but found the headlight only shutoff with the power rather than the intended switch. Which means the controller's wiring has a problem. Additionally the PAS isn't working and there is no way to access several functions in the settings panel (P011-P015). The latter might be mine own fault, but have read similar problems from other consumers, and the headlight function can only be a controller defect. That said, I am trying to get support from customer service.Overall, I would recommend getting a 1500watt motor, making sure you have the right wheel, and exploring other companies; perhaps with a better market-footprint.
