Data and facts about the Transition Regulator CX XT
| Suspension travel | 160 mm |
| Weight | 21.62 kg |
| Motor | Bosch Performance CX |
| Battery | Bosch Power Tube 600 |
| Fork | Rock Shox ZEB Ultimate |
| Rear shock | Rock Shox Super DeLuxe Ultimate |
| Drivetrain | Shimano XT |
| Front brake | TRP E.2.3 |
Under 22 kilos, despite the thick ZEB fork, massive Enduro tyres and lots of robust gravity parts - the Transition Regulator CX not only sets the best value on the scales, but also makes an unmistakable statement: for the traditional label from the USA, All Mountain stands less for leisurely mountain tours than for trail rodeo on tricky descents.
If you know where this piece of sports equipment with its anti-comfort aura comes from - namely Bellingham, Washington - you'll know why: it really gets down to business there! Steep terrain interspersed with everything that makes relaxed cruising impossible: fat drops, rockslabs, skinnies. It's practically a biotope for bikes that have been bred to master the most demanding terrain - not to enjoy the panorama on the mountain.

Easy to customise
The key data: 160 millimetres of travel at the fork, 150 millimetres at the rear and mullet tyres. Practical: If you want to increase the rear suspension to 160 millimetres, simply swap the shock for a model with five millimetres more travel. To ensure that the Regulator doesn't drag you down the Bellingham Steeps too much and remains easy to handle, the following applies: weight comes before reach. That's why there is a permanently installed battery with only 600 watt hours in the down tube. This not only saves almost a kilo compared to the 800 Powertube, but also allows for a slimmer, lighter frame design thanks to the closed down tube.
The only criticism of the equipment: the Shimano XT drivetrain seems overwhelmed by the power of the motor when changing gears. The SRAM transmission gears of the competition change the sprockets much more confidently.
The drive: Bosch Power & 600-series battery
Since CX generation 5, the Bosch motor has been rattle-free downhill and has also noticeably increased its performance: 750 watts of peak power and 100 Nm of torque are now available. Uphill, the new eMTB+ mode sets the benchmark in our view with its extremely sensitive response behaviour and enormous overrun. Although the power unit is no lightweight, it is otherwise hard to beat.
Bosch also remains unrivalled in terms of efficiency with a comparable battery size. However, in combination with the small 600 watt-hour battery, the Regulator CX was the first to run out of juice after around 1600 metres of altitude in our range test.
Transition Regulator CX, aka Krawallmeister
Off-road, the Transition stands out from the test group as a party animal. While some of the competition sticks to the ground like a washed up whale on flat sections, the lightweight Regulator with its poppy suspension effortlessly picks up speed. The speed can be maintained very well through active pushing - the bike reacts light-footedly, directly and precisely. Winner on points in the play instinct rating!
Stone fields and cross roots do not completely disappear into thin air under the Transition, but experienced pilots benefit from pleasant feedback from the ground and firm support on hard landings. Those who like to ride actively and leave the throttle open will love the Regulator. However, it offers too little comfort for classic all-mountain use.
On the climbs, the bike delivers exactly what you would expect from an all-mountain bike: long chainstays, excellent traction and good manoeuvrability. The Transition climbs even the nastiest ramps on our test track with ease - only the Cannondale Moterra 1 climbs even better.
Conclusion from Max Fuchs
The Transition Regulator CX is the sportiest bike in this test. With its direct and lively character, it thrives under the dictates of experienced riders. Falling downhill and taking every obstacle in its stride - that's its speciality. Due to its lack of comfort and range, it does not fully fulfil the requirements of an all-mountain bike. Thanks to top marks in the lab and in practice, it still secures second place! - Max Fuchs, test editor and photographer at BIKE
