Battery and electrical safety. Lithium-ion batteries can catch fire if they're damaged or charged wrong. Never open a battery pack, and stop using any battery that's swollen, hot, wet or smells burnt. Every edit to this page is checked by a second person before it goes live.

This page lists the common replacement parts for the Aventon Level 4 ADV commuter, step-over and step-through. Specs come from Aventon's Level 4 ADV spec page, its step-through page, its ADV vs REC guide and Aventon's parts pages, read Nov 9, 2026. The ADV uses an Aventon Ultro S mid-drive motor (100 Nm, 750 W peak), so the rear wheel comes off like a regular bike's. It shares its frame and display with the Level 4 REC, but its motor, brakes, drivetrain and battery differ, so don't mix parts lists. Aventon's parts pages often don't show a price until you pick your model, so where no price is given below, check the page or ask Aventon.

Electrical parts on this list must match this exact model, and they are fitted at the external plugs or by a pro. Never open the battery, controller, motor or display. For battery and charger trouble, start with battery won't charge and e-bike battery care.
