About this eBike
The Transition Regulator CX is a carbon full-suspension mixed-wheel e-MTB intended for trail and all-mountain riding. This listing is for a Medium frame in Salish Sea Blue with 150mm rear travel and a 160mm front setup; photos show the Regulator CX crossbar/diamond frame with Bosch Performance Line CX motor and integrated 600Wh PowerTube battery. The bike uses a Bosch Performance Line CX (BDU38) smart system motor with Bosch PowerTube 600Wh and wireless Bosch controls. Factory Deore spec includes Shimano Deore 12-speed gearing, Shimano 4‑piston hydraulic brakes and Maxxis tyres; the photographed machine has Öhlins RXF 38 fork and Öhlins TTX2 rear shock and a RockShox Reverb AXS dropper which appear to be owner-fitted and should be confirmed.
Who is this bike suited to?
- Likely rider/use case: spirited trail and all‑mountain riding where full-power e-assist and big‑trail capability are required.
- Suitable terrain: rough singletrack, technical climbs and descents rather than urban commuting.
- Medium-frame riders approximately 5'7"–5'11" (170–180cm), estimated from the available Transition 2025 sizing information.
Size and rider fit
Estimated rider height: 5'7"–5'11" (170–180cm). No exact manufacturer rider-height chart was found in the available manufacturer/support pages. Estimate is based on Transition's Medium Regulator CX geometry, 455/450mm reach and typical modern full-suspension e-MTB sizing; riders between sizes should test ride and consider preferred reach, saddle height and dropper insertion.
Condition, history and modifications
Known marks, wear or faults:
Small scratches on the front fork and a couple of small cosmetic marks in the frame
Service history:
Serviced before I bought it but nothing since as has only done 150 miles
Upgrades / modifications:
Ohlins rxf 38m2 160mm fork
Ohlins ttx2 160mm air shock
Rockshox reverb AXS 200mm dropper post and lever
Kiox 400c display
Bike is in excellent condition and only done 150 miles. Selling it as it’s not being used
