Hiya. 21st-Century urban Canadian here... used to passing hundreds and thousands of folks trapped in huge carriages ("cars") w/ "just" 500 watts of (continuous) power.
Plus One! LOVE torque. Where the goal is fastest AVERAGE speed in a "stop and go" urban world.
That would make it slower; assuming the OP wants a faster bike he'd need a larger diameter wheel on the motor.
... and ignoring higher RPMs.
