Transition Regulator CX Carbon XT 2025 Electric Bike

The Regulator CX is our 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 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.

Features

150 / 160mm Mixed Wheels

The dedicated mixed-wheel platform with 150mm rear and 160mm front travel make the Regulator CX nimble and responsive while delivering powerful assistance for the steepest of climbs. With a 64.5 degree headtube angle and short, 27.5" wheel specific chainstays, we were able to make the Regulator one of the most maneuverable eMTBs we've ever ridden. This keeps the ride fun and engaging on everything from smooth flow trails to steep tech. A geo adjust chip in the lower shock mount allows riders to fine tune geo to their preferences.

High Power to Weight

The Bosch CX system delivers the highest power-to-weight ratio possible. Perfect for riders who want lighter ride characteristics from their eMTB that excels in a wide variety of terrain. Complete builds come in at just over 47lbs while still delivering 85Nm of torque for powerful assistance.

Bosch Performance CX Motor

Powered by the Bosch CX system, the Regulator gets the legendary reliability of Bosch in a lightweight package giving you 85nm of torque and 600w peak power. While powerful, the system also provides an incredibly natural feel that delivers power without breaking traction, keeping your momentum and helping you clear technical trails.
