propeller propulsion bike

 
The idea for this project is to use a propeller and a combustion engine to power a regular pony bicycle. With this solution we could avoid the use of any complicated mechanical transmission mechanism. Even though the efficiency of the propeller propulsion is substantially less than gear drives, we measured very favorable fuel consumption because the motor operates always at the optimal ~3000 rpm/min. On 100km range it consumed 2.33l gasoline*. The maximum speed the bike could reach is 50-60 km/h.
