Transition Regulator CX Carbon Deore eMountain Bike in Salish Sea Blue

Season:2025

Brand:Transition

Code:ULBaeShsilaSERD.BRC.XC.GE

The all-mountain steed is here to deliver fun on every ride.

The 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 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 85 Nm of torque for a powerful and natural ride feel. Enclosed in the downtube is a 600 Wh battery to power big rides while remaining sleek and lightweight for the category. For those looking for extra range, the 250 Wh Bosch PowerMore range extender will power you up to 850 Wh 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:

  • 150/160 mm; 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, Transition was able to make the Regulator one of the most manoeuvrable eMTBs they'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 47 lbs while still delivering 85 Nm of torque for powerful assistance.
  • Bosch Flow App
    For those looking to dig into the settings, the Bosch Flow app gives you full control and customization. Once paired with your Regulator, you can adjust the power level support and peak power from the convenience of your phone without any wires or a laptop.
  • Bosch Performance CX Motor
    Powered by the Bosch CX system, the Regulator gets the legendary reliability of Bosch in a lightweight package giving you 85 Nm of torque and 600 W 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.
  • Bosch 600 Wh Battery
    Enclosed low in the downtube is Bosch's 600 Wh battery. It's perfectly sized to provide range for big rides without compromising ride characteristics, the 600 Wh battery provides the best range-to-weight balance.
  • Bosch PowerMore Range Extender
    Head deep into the backcountry with the additional PowerMore 250wh range extender. Custom cable management keeps the connection clean and secure.
  • Display
    Easily control the power modes and view battery life via the wireless Mini Remote and slim System Controller top tube display. This minimal display keeps you focused on the trail ahead, while providing all the necessary info you need to keep riding. Giving you everything you need, and nothing you don't.
  • Clean Cable Routing
    Cable routing ports are compatible with 0, 1 or 2 cables and allow brakes to be run on either side.
  • Charge Port
    Transition's custom charge port houses two magnets to ensure it stays closed even on the rowdiest of descents.
    The door easily stays open for charging sessions or installing the range extender.
  • Integrated Protection
    Large hollow lugs on the chainstay protector keep chain-slap to a minimum while protecting the frame.
    A pre-installed mud-guard keeps dirt and grime out of the main pivot area.
  • Geo Adjust Chip
    The Regulator CX features a geo-adjust chip at the lower shock mount to fine tune geometry.
  • Integrated Chain Guide
    Designed in-house, Transition's pre-installed chain-guide ensures you never miss a pedal stroke.
