I'm wondering how to calculate the torque required for my Homeade v belt drive motorized bike. after some research online it states that I need 100nm to climb a hill effectively. The max torque of the little lifan 152 is 3.1 nm, multiply that by my 12 to 1 gearing ratio, and that gives me about 37nm, that seems awfully low for a 2.5 hp motor that's only geared for 23mph? I know @Sidewinder Jerry has posted some stuff about this in the past, but I can't seem to find it.
