Geared hub motors, such as those in our 250w and 500w Hub Kits, are great simple systems for lower power levels, as the Planetary Gear System within the motor helps you get better low-down torque (for acceleration and hill climbing) from a lower output motor.
The gears inside are made from a nylon composite material, to allow them to be durable and quiet. The main benefit of the geared motor is total freewheel ability (so, zero rolling resistance), meaning you can pedal the bike easily if you are not using the battery. They are also much less obvious than the larger Direct Drive electric bike motors, and weigh considerably less. Geared hub motors are independent of the bike’s gears, meaning they are easy to use, with the selected gear bearing no influence on the performance of the motor.
This system works in conjunction with the gears on the bike, so when different gears are selected, the motor gives a different level of performance. Just like a car with a manual gearbox, low gears are for high torque (for take-offs and hill climbing), and higher gears give higher speeds. Therefore, the performance of mid-drive systems are broader in their scope than hub motors of the equivalent power output. There are two alternative methods for Mid-Drive motors to provide power.
The controller is an important part of an e-bike kit. It manages the requirements of the different system components, and has some safety features built in (i.e., low-voltage cutouts to protect your battery when running flat). Hub motor systems have external controllers, which are normally housed in bags supplied with our kits, with excess cabling and plugs stashed inside too, and mounted somewhere on the bike (in the triangle or under the seat normally). Some batteries include a controller box at the front of the battery. This means it’s a simple replacement if the controller fails, and you also have somewhere to stash any excess cabling from your kit.
Controllers are internal (located within the motor) in our mid-mount systems. These are Programmable controllers, which can be plugged into our computer via USB to set various motor control parameters. We also sell external ‘Magic’ Controllers, which are multi-voltage programmable controllers, that can run virtually any e-bike motor up to 1000w (continuous output = 30amp, peak output = 60amp). Plug changes may be required to run with other motors, but they do work for most motors. These Magic controllers can be purchased with plug-compatible handlebar controls – call us if you require a complete set, or, we can fit plugs to match your existing setup if required.
