Chain Drive Bicycle Engine Kits | |
|
Dependant on rider size, riding conditions, sprocket and engine choice a top speed of 30 + mph is easily attainable with a 33cc engine and we offer many size and brands of quality engines. All kits have a centrifugal clutch between the gear box and engine, (so the engine can idle and stay running while coasting or stopped). The custom hub has threads on both sides. On the right side (your pedal side) gears remains the same, you can coast and change gears. The left hand threaded freewheel sprocket on the left side of the hub and the gear on the gearbox drives the engine side. Our gear box will never need replaced and it's made to last a Life Time and them some. |

We have current customers who have more than 50,000 + miles on our kits (gear box and rear custom hubs) and they are still running strong since 1984. The Robin - Subaru, Honda, Mitsubishi & Tanaka engines are rated for 600 + hours of use. We have had many of these engine run 2 & 3 times the rating. Engine life in miles. 600 hours @ 30 mph = 18,000 miles. Your engine could get as many as 54,000 miles or more. |
