These strong and durable replacement cranks integrate seamlessly with Biktrix eBikes equipped with the Bafang Ultra system. 170 millimetres in length, this set of two black anodized crank arms act as replacement parts or key components for a DIY-build.
*Takeoff parts are parts which have been removed from brand-new, never ridden bikes. These parts may have some minor scuffs or fitment marks but are identical in performance and specifications to the brand-new version.
