Color: 36VThumb Kit
This kit was very hard to install, and required a lot of modification both to the mounting plate and to the bike. Now that it is on the bike I actually really like it. But if you don’t have your own shop and confidence to mount things yourself it can be very daunting. It is not recommended for the beginner. I ended up just using 40 V battery packs that I got from Harbor freight, and they were great with a 36 V kit, I get about 2 1/2 miles of range with that. That is plenty for the family bike rides that we go on. This was written on day two and I’ve only taken it out twice but so far so good. I would say that if you are building something from scratch and not trying to retrofit the bike this works extremely well. If you’re trying to fit this on an existing bike as a plug and play option just now but it will require a lot of work. Week update: Things are still holding up. I ended up switching which bike this would go on because I found a cheap Walmart bike. Surprisingly I had to basically put the mounting plate back to the way it came with the kit. So if you are looking for a bike that this will fit on with only slight modification.

Color: 24VThumb Kit
weak instructions which is just a sticker on the controller, the bracket does not fit which makes it impossible to truly know cause the description is not really there just fits most bike since I have an old bike frame I hoped that was good enough. the description of volts variety said 24v, 36, but when got box sticker only said 24v. so use one description for all models in the basic bold title is all one really sees . after I ordered i did see in the long description a differents but who knew where the mistake really need to say on both the fine description to the bold on in your face one . i do not know how it works sadly i did hook it up to a battery and never ran so i can only assume it does not work anyways. the business does not allow you to contact for support..

Once you get the motor on, the hard part is done. I had to modify the motor bracket a lot and shim the motor to get the gears in line to work correctly. Once that is done, it's just a matter of putting the throttle and controller where you want it and hook it all up, zip tying everything. Mine happened to have the motor connected backwards but that was just a matter of switching the motor wires. All said and done it does take some work but it seems to work well. I weigh around 215 and it holds 13 mph. I bought an 8 amp hour battery. I bought the thumb throttle 36v kit.

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 01/11/2021 Here 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.

The motor and controller seem robust enough. I’ve got bikes with a couple thousand miles on hub motors so we’ll see how a chain drive works out. The mount is a whole different story. I don’t think that you could get a perfect universal mount. This one was cut up and a mount bracket welded to a seat stay. The end result is a nice looking and strong setup but if your not a fabricator this may not work for you. I have a full fab shop so this wasn’t a big deal. If you only have a set of wrenches you’ll be extremely lucky to get it to fit.
