The Transition Regulator CX is Transition 's all-mountain workhorse designed to provide a nimble and responsive ride with big power. No trail is too tame or gnarly for the dedicated mixed-wheel platform with 150/160mm travel and geometry that promotes agility and playfulness. The Transition Regulator will be the choice for riders looking for a chassis that excels in a variety of terrain with the added assistance of a Bosch Performance CX drive unit. Known for its legendary reliability, the CX drive unit delivers 85Nm of torque for a powerful and natural ride feel. Enclosed in the downtube is a 600Wh battery to power big rides while remaining sleek and lightweight for the category. For those looking for extra range, the 250Wh Bosch PowerMore range extender will power you up to 850wh for all-day adventures. This combination provides the best range-to-weight ratio for those who value lighter ride characteristics, giving you the best of both worlds with one of the most reliable, powerful, and intuitive motor systems available on the market.
