If this is your first time to our web... Welcome! We are the makers of The ENCORE ENGINE SYSTEM:

with "shift on the fly" technology.


We offer Honda 4 stroke engines, or 50cc 2 stroke engine. Our warranted engines for bicycles drive the rear tire of human powered vehicles, "the bike", with confidence and dependability.


Our mount systems fit all bicycles. We guarantee fit if we know the bike you plan to use. No other Bicycle engine manufacture offers that". And we are legal.


Our mounts fit  American, Japanese, Chinese, Italian, Korean, and  other engines with 78 mm clutches. The world standard.


Great for every day chores and that 20+ mile trek to work.


View our Bicycle Engine Specifications in 2 and 4 stroke varieties.  Call us at 406-652-6766 or order online at www.shop.bikemotor.com.


We offer ready to ride, fresh out of the palate shipped, fully assembled motorized bikes, recumbent bicycles and tricycles.

300 pound riders climb  8% grades without peddling, but they can! Dimension Edge is designed to augment the human's ability to propel a bicycle.

Clean, dependable, simple and quiet bicycle engines to motorize bikes. Engine systems start at $499. Or as shown, aluminized with shift on the fly,  $699 with FOUR interchangeable gearing ratios!

Four top reasons people choose our design: DBL click bicycle engine pictures.

  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.
