A smaller Drive Wheel is like a Lower Gear!





Thrust naturally increases as you select smaller wheel sizes, while the torque of the motor is independent of wheel diameter. Thrust is most convenient for estimating the climbing capacity of the vehicle, and it is what most people actually mean when they talk about 'torque'. To a first order approximation, the pounds thrust needed to overcome gravity when climbing a hill is simply weight * %grade

This Yurba Mudo has the motor connected to a crank
 sensor. And will not run smoothly near the
 top end of out put because of it.
