CUBE Stereo Hybrid ONE44 HPC Race 800 review

Where the Stereo Hybrid ONE44 HPC Race 800 fits

The clearest match is sporty trail and mountain-touring riders wanting a carbon-front Bosch e-MTB with long range and balanced handling rather than enduro-level travel. This review is based on the Evans specification, manufacturer information and clearly identified independent coverage; it is not presented as a RideIn hands-on test.

Motor, controls and UK legality

Evans lists Bosch Performance Line CX, Max 120 Nm.. The controls are described as Bosch Mini Remote.

The current Performance Line CX system is listed with a maximum 120Nm configuration and uses a wide 10–51T twelve-speed cassette. That gives strong support on technical climbs, while the Kiox 400C and Mini Remote keep ride data visible without a large exposed display.

High torque should be managed rather than used indiscriminately: a progressive assistance mode and an easy gear preserve rear grip, battery and drivetrain on loose climbs. The exact software tune and mode set should be confirmed by the Bosch dealer at handover.

For use as an electrically assisted pedal cycle in Great Britain, the maximum continuous rated motor power must not exceed 250W, assistance must cut out by 15.5mph and the pedals must be able to propel the bike. Check the label and delivered configuration rather than relying on a category name.

Battery, charging and realistic range

The listed battery is Bosch PowerTube 800 Wh. No numerical range is stated in the accessible listing; route, rider, weather and assistance level materially affect distance

The integrated 800Wh PowerTube suits long mountain days and repeated elevation gain. It also adds substantial mass, so riders doing short trail-centre loops may be carrying capacity they rarely exploit.

A two-amp charger is slow for an 800Wh pack and makes overnight replenishment the practical norm. Independent ONE44 coverage has specifically criticised slow charging on related builds, so regular back-to-back long days may justify pricing a compatible faster charger.

Use only the approved compatible charger, charge away from escape routes and stop using a battery that is damaged, swollen, leaking or unusually hot. Ask for the replacement-pack price and warranty conditions before the original battery becomes a problem.

Frame, fit and ride character

The frame specification is C:62® Monocoque Advanced Twin Mold Technology Carbon Front Triangle, Aluminium 6061 T6 Rear Triangle, Efficient Trail Control, FSP 4-Link, Agile Trail Geometry, Boost 148, UDH™, Full Integrated Battery, Advanced Internal Cable Routing. Fork and suspension details are Fox 36 Float Rhythm GRIP, E-Bike Optimized, 150mm Travel, 15x110mm; Fox Float Rhythm RC, Adjustable LSR, Two-Position Lever, Trunnion Mount. The tyres are Schwalbe Nobby Nic Performance 2.6in.

The Fox 36 Rhythm fork supplies 150mm travel while the Float Rhythm rear shock controls 140mm, creating more front reserve without the slow, heavy feel of a 170mm enduro bike. An angle-adjustable headset lets an experienced rider tune steering character within CUBE’s approved settings.

Bike Magazin describes this exact Race family as stable, comfortable and well balanced for sporty touring, while EMTB-Test finds the ONE44 platform sporty and good value. Shimano MT420 four-piston brakes with 203mm rotors are capable, although they are a sensible cost control beside the carbon frame and Fox suspension rather than a prestige component.

Brakes, transmission and everyday equipment

The bike uses Shimano BR-MT420 Hydraulic Disc Brakes, 203/203mm Rotors. Transmission is Shimano Deore SL-M6210-IR; Shimano XT RD-M8200-SGS Shadow Plus, 12-Speed; Shimano Deore CS-M6200, 10-51T. The equipment information is CUBE Dropper Post with Internal Cable Routing.

A remote dropper, tubeless-ready wheels and Nobby Nic 2.6-inch tyres make the bike trail-ready without immediate essential upgrades. The mixed carbon/aluminium frame demands correct torque settings and inspection after impacts.

This is not the utility-oriented alloy Pro frame: the Evans specification does not emphasise carrier or mudguard mounts. Owners planning year-round transport should verify compatible protection and carrying options instead of assuming every ONE44 shares the same fittings.

What the published evidence tells us

Evans listed this build at £3,999 when RideIn checked it on 29 August 2026. Prices can differ by colour or size, and stock can change; a discount against a reference price does not by itself establish value.

Evans and CUBE’s exact product page establish the current Race hardware and travel figures. Motor maximums can depend on Bosch software configuration, so the 120Nm number is treated as an available ceiling rather than a constant trail output.

Independent exact-model and platform tests agree on balanced handling, comfort and strong value, while noting that the components are not uniformly high-end and the ONE44 has less downhill reserve than longer-travel bikes. Those are credible family themes rather than invented personal impressions.

Advantages and disadvantages

The useful comparison is whether the complete build suits the regular route, storage and service plan. A premium motor cannot compensate for poor fit, while a modest component can be entirely sensible on the right type of bike.

• Advantage: Balanced carbon-front trail chassis
• Advantage: Fox suspension with useful travel split
• Advantage: Bosch CX power and 800Wh capacity
• Advantage: Dropper, tubeless-ready wheels and adjustable geometry
• Disadvantage: Slow two-amp charger
• Disadvantage: MT420 brakes are functional rather than premium
• Disadvantage: Heavier and more complex than a hardtail
• Disadvantage: Less descending reserve than the ONE77

Buying checks and RideIn verdict

Confirm the exact product code, frame size, colour, battery capacity, assistance configuration and included equipment before paying. Ask which Evans branch or authorised dealer will handle electrical diagnosis, warranty labour and replacement components, then test the brakes, controls and fit before committing to regular use.

The HPC Race 800 is the range’s persuasive do-most trail bike: long-legged enough for serious riding, but not so enduro-focused that ordinary tours become a chore. Its value rests on the frame, motor and Fox suspension rather than top-tier parts everywhere.
