This page lists the common replacement parts for the original Velotric Discover 1, high step and step-thru, not the later Discover 1 Plus or Discover 2. Specs are for the stock bike as sold; check your own bike before you buy. Full details are in the Discover 1 and Nomad 1 user manual. Velotric's Discover 1 product address now shows the Discover 1 Plus, which has different tires and other parts, so don't order from that spec list.
