I noticed that they tend to use a reduction between the motor and the shaft, but they also all tend to use the Etek motor as well and that is a low torque motor that likes to run at higher speeds, my motor is said to top out at around 2,000 or a bit higher, bump the voltage up (like I plan to do) and you will get a bit more top end speed out of it, it's also designed to power a 1,200 pound 4 wheeled cart with wide tires on grass with 2-4 people in it, not a 600 pound motorcycle on pavement with silica rubber touring tires and a single person, I agree that I might be pushing what the motor can handle but I'd like to keep it simple and I figure with the gear ratio that I have I'll have to add a heavy duty controller to handle the high amps needed to start from a dead stop.
