Specs are for the stock bike as sold; check your own bike before you buy. This page covers the Tern Quick Haul P9 (Gen 1), sold from 2022, a compact cargo bike on 20 inch wheels. It uses the Bosch Performance Line mid-drive (65 Nm) on Bosch System 2; see Bosch motors explained. The D8 and P8i builds and the longer Quick Haul Long can differ in drivetrain, battery and display, so match the part on your bike before you order.
Electrical parts on this list must match this exact model and are fitted at the external plugs or by a pro. Never open the battery, motor, display or charger. Battery and motor service on the Bosch system is dealer work: a Bosch dealer reads faults with its diagnostic tool and updates the software.
