Specs are for the stock bike as sold; check your own bike before you buy. This page covers the Cannondale Tesoro Neo X 2 from 2023 on, the version built on the Bosch smart system, in standard and StepThru frames. Two builds are listed: the US StepThru (model code C66262U) with the Bosch Performance Line Sport and microSHIFT drivetrain, and the international Tesoro X 2 (C66342U) with the Bosch Performance Line and Shimano Deore. See Bosch motors explained. Brakes and drivetrain differ between the two, 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.
