Transition Regulator SX Carbon Deore eMountain Bike in Madrone Gold

Season:2025

Brand:Transition

Code:DLGenordaMERD.BRC.XS.GER.

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

The Regulator SX is Transition's all-mountain eMTB designed to provide a nimble and responsive ride. No trail is too tame or too gnarly for the dedicated mixed-wheel platform with 150 mm rear and 160 mm front travel and geometry that promotes agility and playfulness. The Regulator SX will be the choice for riders looking for a chassis that excels in a variety of terrain with the added assistance of a Bosch SX drive unit delivering 55 Nm of torque from a 400 Wh battery. Coupled with Transition's SBG geometry, you have an eMTB experience close to that of non-assisted bikes. 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 and intuitive motor systems available on the market. For those looking for extra range, the Bosch range extender will take you up to 650 Wh for all day adventures.

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 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 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 Line SX
    Powered by the Bosch Performance Line SX system, the Regulator gets the legendary reliability of Bosch in a lightweight package giving you 55 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 400 Wh Battery
    Enclosed low in the downtube is Bosch's 400 Wh battery. Perfect for local laps where you want the most manoeuvrable eMTB in the market.
  • Bosch PowerMore Range Extender
    Head into the backcountry with the additional 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.
  • Integrated Chain Guide
    Designed in-house, Transition's pre-installed chain-guide ensures you never miss a pedal stroke.
