Electric Mountain Bike (EMTB) Controller Guide

An e-bike controller is your point of contact to control your electric bikes power output, activate specific functions such as lights and walk assist model and a visual signal of key information such as current mode of assistance and remaining battery life. This guide breaks down the controllers fitted across the bikes sold through MTB Monster, so you can assess which system best suits your needs.

Bosch

Bosch controllers are intuitive and easy to use. Each controller has both the ‘+’ and ‘-’ buttons to cycle through assistance modes, a long press on the ‘-’ button activates walk assist mode while a long press on the ‘+’ button activates any lights fitted and linked to the system. The left and right arrows take you through the different statistics on your display (if fitted). Except for the mini remote (on the left) which is cycled through via the square button.

Shimano

Shimano controllers are wired into either a junction box or a display to work correctly. Depending on the model, for example the EM800 (on the left) can only cycle through assistance modes requiring a junction box or a display to function. However a EN6N-600 (on the right) can function as a standalone controller, with buttons for power, assistance modes, lights and options to cycle through the display metrics.

Fazua

The Fazua Ride 60 ring controller (on the left), has no moving parts, the moving ring is held in place via magnets this is to help clean the controller when dirty. The controller features an on off on/off switch, changes mode and activates boost mode. The ring controller needs to be paired with the Fazua LED display in order to operate correctly.

The Ride 60 Control hub (on the right), eliminates the need for the separate top tube display as it combines the two items into one. Displaying the current state of charge and powering the system on.

DJI Avinox

The DJI Avinox system incorporates two bluetooth controllers with customisable buttons. The left controller buttons take care of, assistance modes, and both the boost mode, by holding the up button, and walk mode by holding the down button. The right hand controllers cycle through the different system data, such as mph and distance travelled. These controllers also enable quick assist to access more operations and faster commands.
