Imaging, 300 pound riders climb  8% grades, thanks to interchangeable gear ratios. Few people want to do over 40 MPH . But they can!

Clean, dependable, simple and quiet bicycle engines to motorize bikes. Engine systems start at $469. Fully aluminized at $619 with FOUR interchangeable gearing ratios!

Four top reasons people choose our design:

1. SAFETY: Shock absorbing engine mount handles the bumps. No belts, no chains to derail causing sudden lock-up. Far less maintenance, weight or risk. Peace of mind when sharing the road with cars and trucks.

2. STREET LEGAL: STILL a bicycle.  Engage and disengage engine while riding. That's the law. While disengaged the engine mount is just a bike rack. Cool, a real neutral. Pedal as much or as little as you like. We GUARANTEE IT!

3. VALUE: "SHIFT ON THE FLY" Simply engage while riding, the engine self starts! No hand pulling needed. No batteries. No troubles. No wasted gas. Add centrifugal clutch option for a net price increase of $89.

4. DIVERSITY: We guarantee a fit on your existing bicycle! Just tell us what bike you plan to use. Specialty bikes have become a regular with us. We offer complete, ready to ride,  fresh out of the crate, motorized bikes.
