Cube AMS Hybrid ONE44 Race – Test winner in technical review

With the AMS Hybrid ONE44 Race, Cube is at the forefront of the light e-MTB segment – and not just from its own perspective. In a major comparison test in the 05/2025 issue of BIKE, the trail bike came out on top against seven other full-suspension bikes and impressed across the board in the ‘Light All Mountain’ category.

“CUBE proves that the light category can also make sense on a smaller budget. The AMS Hybrid ONE44 Race is balanced through and through and impresses above all with its great riding fun and low weight – despite the need to economise on equipment. Clear victory in the duel with Canyon!”
BIKE Magazine, Issue 05/2025

This assessment sums up what the ONE44 is all about: a well thought-out overall package for sporty e-mountain bikers who are looking for performance – without letting excessive motor power or unnecessary weight take away from trail performance.

How the Cube AMS Hybrid ONE44 Race performs on the trail

The Cube AMS Hybrid ONE44 Race strikes a successful balance between agility and smoothness on the trail. The geometry reacts directly but always remains predictable – ideal for flowing lines and technical passages. The riding position is suitable for both long tours and steep climbs, where the bike’s low weight and steep seat angle make it feel like it is pulling forwards.

Downhill, the handling is controlled and safe without being sluggish. The suspension works sensitively, offers comfort and provides plenty of traction – whether on flowing trails, rooted descents or quick changes between tight bends. If you like to ride actively and are also out and about in more demanding terrain, you will get exactly the right mix for sporty trail experiences.

Technology behind the frame: Cube AMS Hybrid ONE44 Race with C:68X carbon

The frame of the Cube AMS Hybrid ONE44 Race is technically sophisticated and designed for maximum performance. The C:68X® carbon technology used combines 68% high-modulus carbon fibres with nano-particles and minimal resin content – this ensures a particularly light, stiff and responsive frameset, ideal for sporty use on the trail.

Thanks to the Advanced Twin Mold Monocoque process, Cube can control the wall thicknesses and save material where it is not needed. This reduces weight and increases structural stability at the same time. The Agile Trail Geometry provides the right amount of manoeuvrability and smoothness, while the low centre of gravity and compact rear triangle ensure plenty of control – even on demanding terrain.

The overall technical picture is rounded off by the FSP 4-Link kinematics. This special four-bar linkage system on the rear triangle ensures that the suspension travel remains active even under load – for example when pedalling or changing direction quickly. At the same time, it minimises influences on the drive and thus improves efficiency and traction. The result is a frame that is not only light and stiff, but above all technically sophisticated and ideally suited to sporty trail use.

What the Bosch Performance Line SX delivers in the Cube AMS Hybrid ONE44 Race

With the Bosch Performance Line SX motor, Cube is following a new line in the E-MTB segment: lighter, more compact and closer to the classic bike feeling. Instead of brute thrust, the SX offers finely dosed support – ideal for riders who pedal actively and only want subtle support. The motor delivers 250 watts of continuous power with 55 Nm of torque, which is perfectly adequate for sporty trails – especially as the bike itself weighs just 18.8 kg.

The CompactTube battery with 400 Wh is fully integrated and matched to the Smart System. If you are planning longer tours, the Bosch PowerMore 250 additional battery is an uncomplicated option: the small range extender can be attached directly to the down tube thanks to the Toolmount – the required brackets are part of the official retrofit kit. At just 2.39 kg, the additional battery hardly weighs anything, but provides noticeably more range.

Gears, brakes & wheels: The equipment of the Cube AMS Hybrid ONE44 Race

Instead of showmanship, Cube focusses on function and durability. The Shimano XT 12-speed drivetrain works with the usual precision, while the Deore M6120 brake system with four-piston callipers and 203/180 mm rotors provides reliable deceleration – even on longer descents.

With the Newmen Performance 30 wheels (tubeless ready) and Maxxis Dissector tyres with EXO+ carcass, the bike remains puncture-proof, fast when setting off and yet grippy when cornering. The cockpit is high quality with a 780 mm wide Newmen handlebar, the brand-typical short Cube stem with integrated cable routing and a lowered Cube dropper post, which is internally routed.

Key trail features of the Cube AMS Hybrid ONE44 Race

The Cube AMS Hybrid ONE44 Race is not an E-MTB for compromises – but for those who take the terrain seriously. With its lightweight carbon frame, finely metered Bosch SX drive and equipment that focusses on function rather than show, it delivers exactly what a modern trail bike should: Direct handling, technical clarity and the secure feeling of being well on your way on any trail. Anyone who rides with passion and values control, efficiency and real riding fun will find a reliable partner in this bike.
