now i thought to put sprocket of 10 on the engine then to to the sprocket of the paddles the smaller one to the biggest one of the bike,
its downhill bike , that why i choose that low speed for the power with 10s battery ,
now i want to know where i can i buy sprocket bore for the engine 10mm dia, about 10 teeth for bicycle chain,
u might have better idea for me for the drive train? my wheel atm is 26" maybe will be smaller in the future (20" fatbike wheel)

Watts: 5300w
Diameter of shaft: 10mm
