Keep Your Controller Installation Organized

A dedicated controller enclosure can help create a cleaner installation by keeping the controller and wiring contained in one location.

It can be useful for mounting a controller:

• Under the seat

• Along the bicycle frame

• Near a rear rack

• Inside a custom battery/controller compartment

• On a DIY conversion frame

The final mounting location should provide adequate clearance and cooling for the controller.
