Even if you've been investigating electric bicycle motors for a while you may not realize the difference between one electric bike motor and the next. You see there are many different designs electric bicycle motors which contribute differently to their performance. It all gets a bit complicated but to keep things simple lets compare the motor of a BionX kit to other electric bicycle motors from other electric conversion kits. Why? Well because the motor of a BionX kit is the best available!
So first let's talk geared and un-geared motors. First off, what kind of gears do electric bicycle motors have and what purpose do they serve? Well, because electric bicycle motors have more torque and power at low speeds gears are often used to make less sophisticated electric motors put out more rpms, which translates into more speed. They do this by using planetary gearing.
Planetary gearing is a whole different topic to itself. Let it suffice to say that, for the purposes of electric bike motors, planetary gearing turns low rpms into high rpms. For now, let's just take that for granted.
Having gears isn't that great though, and high quality electric bicycle motors like those in the BionX bicycle motor kit are designed without gears for three main reasons:
The next primary design issue is how power is transferred from the battery to the electric bike motor. BionX kits are built using the more efficient, lighter weight, and lower maintenance design: brushless motors. Brushed electric motors transfer power via copper pieces that literally brush up against the motor coils as they spin. BionX kits avoid this for two reasons:
I hope this has provided some insight into why the motor of a BionX kit is so superior to that of other electric conversion kits. There really is no contest.
