Power & Drivetrain Upgrades

Controllers, sprockets, chains, battery parts and drivetrain components. This is where you change how the bike accelerates and how fast it will ultimately go.

Gear before you chase watts

A sprocket change is cheap and reversible, and for most riders it fixes the actual complaint, whether that is weak low-end or running out of top speed. Do that before spending on a controller.

Do the brakes too

More speed makes stock brakes worse in a hurry. Pair anything here with e-moto brakes or a complete brake kit.

Frequently asked questions

Will a controller upgrade void my warranty?

Very likely, and it can also stress the stock battery and motor beyond their design. Read the product page and decide with that in mind.
