One: CNC Machined, Heat treated and Zinc Plated 1.34" OD Drive Roller with 12 mm x 1.50 male threads.
If you want LESS top speed, more pulling power for hills and bucking the wind pick a smaller drive roller.
If you want a FASTER top speed, less pulling power on hills and bucking the wind pick a larger drive roller.
Keep in mind the larger the drive roller you will have to assit pedal the bike up hills and high winds. One: Custom made 60"long throttle cable with the small lever & #16 mini hose clamp.
Four: 8” long Black Nylon ties to secure the throttle cable and kill switch wire to the frame. The kill switch is NOT included. Be sure and add the type you want to the order.

(not a bent thin piece of steel like the others that have tried to copy my product)
Two 5/8” ID x 1-3/8" OD x 7/16" wide High Speed Double Sealed Ball Bearings with retaining ring.
We use one High Speed Double Sealed Ball Bearing on each side of the Drive Roller to support it and remove all the pressure off the engine.
If you have a Ladies Frame bike you will need approxixatly 68" throttle cable.
Some folding bikes like the 20" Dahon need a 72" long throttle due to the way the frame and long up raise on the handle bars.
Front mount kits should be put on Trikes only will come with a 30" long throttle cable with the small black lever and hose clamp. This 1.34" OD Drive roller is way too big and should NOT be used for 99 % of the trikes made. You should use the .930" or 1" OD drive roller. This kit includes everything except the ENGINE & KILL SWITCH.

If you have a 1.60HP Engine and up to 280 lb. rider, mostly flat ground and some rolling hills the 1-1/8" drive roller is the one to pick.
Lighter riders will take off faster and it will pull the hills better. You allways can pedal the bike at any time.
Be sure and let us know if you have the Zenoah 41.5 cc, Robin Subaru EH035, TANAKA PF-4000 Tanaka 33 & 35 cc, TLE33 33cc, or TLE43 42.7cc, Huasheng 140FA 37.7 cc or the 142F 49 cc four cycle.
This kit will also fit some of the China made engines with the same clutch rotor and bolt pattern as the above listed engines.
Note: We can only make a throttle cable for the engines that we sell or know what type of throttle cable you need.
If you have a China made engine or one that is not listed, you will get a cable and a #48 brass end for you to solder onto the cable. Measure twice, cut once!!!
If you need a different size, be sure and add the correct listing to the cart.
This only works with the engines named above. Any no name or China brand engine not listed may or may not work.
I bought this kit to try on my 29er mountain bike. the parts are very well made compared to crappy Chinese bike engine kits I've tried in the past. Hardware like bolts and such feel very well made to. The throttle included does feel a bit cheaply made but works great. I prefer the lever throttle over the twist grip that way no hole drilling or sacrificing shift levers required and I can use any grip I want with it.
The only annoyance with this kit is it is not one size fits all. It seems to be designed for very basic 26 bikes. I had to source some parts to get it to properly fit on my 29er mountain bike. Having disk brakes didn't make it easy ether. I had to jerry rig a way around my disk brakes to move the left side support bracket away from my rear disk brake clapper.
Also having a rear derailleur gear cog will mean the support brackets will not align properly with the support bracket bolt holes on the bike as chain stays for rear derailleur hubs are often wider than more traditional one speed bikes. I also had to do some jerry rigging to make the right support bracket fit there as well. Overall, aside from a few fitting issues with non traditional bikes that can be solved with some extra hardware & creativity, it's a very well made kit and I would recommend this over the cheap Chinese built ones.
