Helio Motorized Bikes

the motor kits that are simply trash. Through tons of experience, we have thrown away what parts are cheap and faulty. Helio specializes in assembly (we have built hundreds), testing and tuning. We have engineered custom made parts for our Motorized Bicycles. These parts, increase dependability,quality and performance. Through trial and error, we have decided to concentrate on the 4 stroke gas motor instead of the 2 stroke. Go to for a write up on 2 vs. 4 stroke bicycle engines. Since we shifted to the 4 stroke, Helio has been able to concentrate on building bikes with these motors. In particular Helio has discovered ways to use both the Honda GXH50 and the smaller GX35. These motors, when mated to an American made Gearbox produce a reliable power plant. Our gas bikes get 150-250mpg and will cruise a comfortable 35mph! Helio is constantly trying to better our product with new parts and models. Don’t settle on a motorized bike that you constantly have to tinker with and ride a Helio!
