Below are some critical reviews about L Faster Electric Conversion Customized Derailleur%EF%BC%88%C2%A8ThumbI've connected the equipment to a 24v SLA battery source and the display indicator in the hand throttle shows 25.8v, even when the key is NOT turned to the ON position. However, the motor will not operate. I'm sure everything is connected properly (even though it does NOT come with any instructions!). I've been emailing L-Fast with the issue and getting either slow or no response, so giving them one more chance to respond. I want to be fair and give L-Fast an opportunity to make this right, but if they don't respond in a timely manner, the motor is being returned to Amazon.
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.
It says "universal fit" and it is not even close to fitting any of my 6 bikes. You must drill holes and make major alterations. Next is the absolute deplorable quality of this kit. As you can see by the pics the bolts to hold the sprocket on are so soft that before it even tightens up they strip as in the pic. I am a retired machinist and did not strip them, they are self stripping. Next, before even starting to attach the kit I luckily took a tip (the only thing that makes sense in that ridiculous video they call instructions) and tested it out. You guessed it, it didn't work. I'm sending this junk back. Don't waste your money folks. This is the worst quality kit I ever saw. It is of such poor quality that the pad that goes behind the spokes is missing one hole. Be prepared to do major work to install this kit, and supply bolts, nuts washers etc.

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.Update: June 25,2020 Here it is in June, motor still runs great. Have modified the 24v to 36v, now. Added a 500w 36v controller, did this only to see if motor can handle the bigger controller. Still works great for me, only draw back was that the rear tire didn’t last long, before tread was nearly gone. No not from spinning out as you might assume, it will spin in sand but you can do that with pedal power if you’ve got the legs. I imagine the added push, plus lots of riding did the tire in, but if I had just rotated the front and back tires, when I first noticed it, would still be riding original. Motor has no noticeable heat, after full ride on my regular 6 mile run. Batteries don’t completely run down on trip, but are lower voltage at end, than original 24v batteries were. As an FYI, I am going back to the 24v as started, because three batteries are harder to balance on bike. I’ve heard of some having trouble with the sprocket failing. I haven’t had that problem, but I can see how it could happen. Wiggle the sprocket side to side, if you feel any sidewise slack, take the nut off, remove the sprocket, and look at backside. You will see a retainer ring with two little dents on it. Use whatever you can make fit both holes, and turn the ring clockwise in. This cover can get loose and unscrew, and drop the metal balls out, ruining the freewheel. That center silver looking piece, that is held with the nut, also will unscrew from the actual freewheel, and you can replace the freewheel using this aluminum bushing. L-faster sells a replacement complete freewheel that will fit this motor, here on Amazon. Happy biking.Update 01/11/2021Here it is January 2021, and still riding. Motor is still working great. Don’t have actual riding miles, I’ve put on it, but on third rear tire. As an FYI, get some good Silicone spray lube, and everytime you take care of cleaning and oiling your chain, spray the backside of the freewheel sprocket on the motor good too. Inside the sprocket, there are metal balls, and if they get dirty or rusty, they can make the back plate unscrew and drop the balls out. You can use the plastic straw looking part on the spray to aim the spray beside center. Spray in good, rotate the sprocket and repeat. If you see dirty looking liquid coming out, do it again. Little bit of house keeping on that and your chain, will make em last long time. I have electrified three bikes, and three trikes, since I started and they are all still going. No I only ride one, but the others are still going, with ages 12 to 74 doing the pedaling. I have to tell you though, for me it’s just as fun to build from scratch as it is to ride. This kit is far better than I had originally thought it would be. You may have to do a little thinking to figure out best way to mount the motor, but everything you need is there. Keep the chain tight, and all the bolts too, and you will get a lot of rides, you will enjoy. Happy pedaling.
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 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.
