Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

Transition Regulator CX Carbon Eagle 90 Electric Full Suspension Mountain Bike 2027 in Clear Blacknight

Season:2026

Brand:Transition

Code:thginKLBRLC09E.XC.GER.62.

The Transition Regulator CX is an all-mountain e-MTB built to make the most of every trail. Its carbon frame combines a dedicated mixed-wheel setup with 150mm of rear travel and a 160mm fork, creating a nimble, responsive ride that can handle everything from technical climbs to fast, rough descents.

Bosch's Performance Line CX drive unit delivers up to 100Nm of torque and 600W peak power with a natural-feeling response designed to maintain traction on technical terrain. A 600Wh PowerTube battery keeps weight and handling in check while providing capacity for big rides, with compatibility for the optional Bosch PowerMore 250Wh range extender when additional range is required.

Transition's GiddyUp suspension platform uses a progressive leverage curve to provide sensitivity at the start of the stroke, support through the middle and controlled progression deeper into the travel. RockShox Ultimate suspension, SRAM Eagle 90 Transmission, Maven Silver brakes and DT Swiss H 1900 wheels complete an aggressive all-mountain build ready for demanding terrain.

Key Features & Benefits:

  • Bosch Performance Line CX: Up to 100Nm of torque and 600W peak power provide strong yet natural assistance, while the compact 600Wh battery helps preserve responsive handling.
  • GiddyUp 150mm Suspension: Progressive suspension kinematics balance small-bump sensitivity, mid-stroke support and bottom-out resistance for confident all-mountain performance.
  • Mixed-Wheel Agility: A 29" front and 27.5" rear wheel combination blends front-end confidence with responsive handling for a playful ride across varied terrain.
