This page lists the common replacement parts for the Aventon Level 3 commuter. Specs come from Aventon's Level 3 spec page and Aventon's parts pages, read Nov 9, 2026. The Level 3 shipped with either Magura or Tektro brakes, so check the caliper before you buy pads or rotors. 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.
