For heavy-use eBikes with Bosch II motors, Connex offers a very robust 3.1 mm replacement sprocket. Designed for use with  1/2 x 1/8 chains, this 18-tooth sprocket offers long, long service. We recommend coupling it with the Connex 1E8 heavy-duty eBike chain for a very long-lasting drive that'll outlast the rest of your eBike.
