Took my Delta Wolf for a spin with engine today. Still smiling.
Got a 4 stroke from Bicycle-Engines.com. Engine runs quite, gearbox screams like a pig.
Had to fit the 44 teeth sprocket from the kit on the axle, couldn't fit any larger. So very little torque.
Calculated the Grubee gearbox ratio at 3.70. Then 11 tooth drive to 44 tooth driven sprocket total reduction of 14.8.
With a 35 kg (75 lbs) bike - not enough torque! Have to pedal on takeoff.
What can I do? Have a 48 tooth #35 sprocket, but where can I get a freewheel #35 10 tooth diver sprocket?
Disc brake failed - burned through my shoes!
