L-faster 24V36V250W Electric Conversion Kit For Common Bike Left Chain Drive Customized For Electric Geared Bicycle Derailleur

Due to mishandling at amazon warehouse a piece was missing when it arrived, as well as the l-faster branded tape was tampered with. However, after contacting the seller, L-faster used express dhl global to send the mounting bracket.product in good working order, pay attention to your rear fork! this may not fit on your bike! i modified the bracket slightly and got it to fit.disclaimer: if you have a need for speed i recommend a 48v+ kit and definitely lithium. This kit goes exactly how fast i expected it to go.The motor's serial number my1016z2 says on other locations that it supports 36v, so I may upgrade my hardware later.

I ordered it for my Quad 4 wheeler bike. Was not hard to install but no wiring diagram. Had to go on another site to get it. I was send a link to a video that only showed the installation of the motor. It works very well for the money.

I used two 12v 21AH Mighty Max YTX24HL-BS for Arctic Cat Prowler 650 wired in series; they are similar to deep cell marine/RV batteries. The batteries are set in plastic storage containers for adverse weather with charging terminals at the top of each container. Even though the voltage is 24v to the motor, each set of terminals above each battery only shows 12v. I wired in a 20w solar panel for charging a 12v battery with a DPST to select 1 battery at a time. You will also need a DPST switch to turn on the electric feed to the motor with a 20amp in line fuse. I went for a "test" ride; 4 miles round trip; I pedaled often but the motor was a tremendous help. You will not go super fast, but the pedaling was easy, not tiring. Upon return, each battery was at 12.59v when they started around 12.71v. The trip had some minor inclines, but I was not exhausted upon return. The batteries are not light weight; I stayed with the 24v to avoid adding the extra weight of more batteries. I don't mind going medium speed; I needed some exercise & this is better than a treadmill in the home & once I determine my "range of operation" I will be confident while exercising. Great product; AAA+++!!! David C.

I put this on a 2018 Husky Girls bike. I powered it with two Neptune 12v 7ah batteries. I replaced the included 24v controller with a 24v 500watt one. Started out with a 20amp fuse inline, this blew first ride. Replaced with 30amp, fired it up, and it flies. Decent length ride, with the small batteries, but upped to 12ah after I saw what it does. I'm not sure what the actual motor rating is, but the motor doesn't get hot, with over a 20amp draw on it. This was the easiest build yet. I've built two trikes, but this was much easier. I didn't use the included chain, since I had some left over 410H chain, I used that. I don't like how the regular 410 chain stretches so I only use the heavy duty chain. On the build, I omitted the outside rubber spoke plate, and removed the dust cover, behind the brake arm. Mounted the center hole of the large sprocket with perfect fit over the spoke ring. It fits with enough clearance of the spokes, and will line up with the motor sprocket, with a little bending of the mounting plate. Be sure to add in a O-ring where you take out the dust cover, or your rear bearings will pickup sand quick. I plan on putting this kit bike, through some hard rides, and I'll follow up if I get any problems. I've got a little over 35 miles on the ride, so far, and haven't done anything, but charge the batteries.Update September 16 Still working great. No problem with motor at all. This is picture of how I worked it out on the Husky bike.Did cut the ends off of the bracket, to make plate fit flush with frame.

EDIT: This is an awful product made with crap materials. The chain snapped after one week of use (3 hours of riding, only about 2 of which were with the motor running) and now I have to get a new one. Just get a hub motor for an extra $60 instead of dealing with the impossible installation and weak product.Good luck mounting this, especially without power tools. Once you finagle this abomination into place it actually works surprisingly, even if it's a bit of an unattractive solution. If you can afford it I'd highly recommend just buying a new cheap e-bike for $500 to $700.
