Hub MOtor
Rear wheel Hub Motor
A rear wheel hub motor is a great option for electric assist due to its affordability, easy installation, and advanced controller systems. However, the crucial question is: how much power is actually needed?
From our testing, motors rated at 1500 watts (2 HP) or more are often excessive. Given the lightweight design of a velomobile, it requires minimal power to achieve efficient acceleration—especially when considering that an average human produces only 200-400 watts of power.
For everyday use, a 500-750 watt motor provides more than enough power.
