CUBE Reaction Hybrid ONE 800 review

Where the Reaction Hybrid ONE 800 fits

The clearest match is long mixed-surface rides and hilly leisure routes where an 800Wh battery matters more than premium suspension, braking or a dropper post. 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 Drive Unit Performance Line CX max. 100 Nm.. The controls are described as Bosch Purion 200 with Integrated Display.

The Evans specification identifies a Bosch Performance Line CX system with up to 100Nm for this build. That is still strong full-power assistance, and the mid-drive benefits from the CUES 11–48T range when climbing.

A ten-speed LinkGlide-oriented transmission trades closely spaced ratios for robustness under e-bike torque. The rider should use easier gears early and reduce pedal force during shifts; even durable components wear quickly if repeatedly changed under maximum motor load.

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. No numerical range is stated in the accessible listing; route, rider, weather and assistance level materially affect distance

An integrated 800Wh PowerTube is the headline feature and gives more energy reserve than the 600Wh Performance or 720Wh ONE. The frame is also PowerMore-ready for a compatible 250Wh range extender, although most riders should first decide whether they genuinely need more than 800Wh.

The supplied two-amp charger will take time to replenish such a large pack. Range remains route-dependent, and carrying excess battery every day adds mass, so a shorter-ride commuter may be better served by the cheaper, smaller-battery model.

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 Aluminium Superlite, Gravity Casting Technology, Agile Ride Geometry, Boost148, Fully Integrated Battery, Advanced Internal Cable Routing, 1.5 Headtube, Kickstand/Fender/Carrier Mounting Points. Fork and suspension details are SR Suntour XCM34 NLO Coil, Tapered, 15x110mm, 120mm (27.5: 100mm). The tyres are Schwalbe Smart Sam, Active, 2.6.

The 120mm Suntour XCM34 coil fork and 2.6-inch Smart Sam tyres provide comfort and confidence on forest tracks, bridleways and easier trails. A coil spring has less rider-specific tuning than the air fork on the ONE 720 and Pro 800, especially across a broad rider-weight range.

MT200 hydraulic brakes with 180mm rotors offer predictable control for ordinary use but are the clearest limitation on prolonged steep descents. The hardtail rear end is efficient and simple, though rough technical trails will expose its comfort and traction limits beside a Stereo full-suspension model.

Brakes, transmission and everyday equipment

The bike uses Shimano BR-MT200, Hydr. Disc Brake (180/180). Transmission is Shimano Cues SL-U6000, Rapidfire-Plus; Shimano Cues RD-U6000-GS; Shimano Cues CS-LG400, 11-48T. The equipment information is CUBE Performance Post, 31.6mm.

Carrier, mudguard and kickstand mounts, plus X-Connect light provision, allow the clean frame to be adapted for commuting and trekking. Accessories are not included, and the fixed seatpost is another sign that this build prioritises range and value over descending equipment.

The integrated battery and cable routing create a neat appearance but increase the importance of a competent CUBE/Bosch workshop for electrical or internal-routing work. Different wheel and fork arrangements apply to smaller frame formats, so exact size details matter.

What the published evidence tells us

Evans listed this build at £2,699 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 support the 800Wh, CUES and accessory-readiness claims. Because Bosch performance figures are updated across model years and software states, this review follows the exact Evans figure rather than substituting a newer range-wide maximum.

Independent Reaction coverage regularly praises the platform’s tidy design, Bosch integration and breadth of use. There is limited exact-model laboratory testing, so conclusions about fork, brakes and handling are reasoned from verified component differences rather than presented as personal ride 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: Large 800Wh integrated battery
• Advantage: Strong Bosch CX mid-drive
• Advantage: Durable CUES drivetrain
• Advantage: Useful commuter and trekking mounts
• Disadvantage: Basic coil fork for the price of a full-power e-bike
• Disadvantage: MT200 brakes limit hard descending
• Disadvantage: No dropper post
• Disadvantage: Large battery and slow charger add weight and charge time

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.

Buy the ONE 800 for distance and motor support, not because the word mountain bike guarantees high-end trail hardware. It is a strong explorer and conversion-friendly commuter; the Pro is the better investment if technical descents are a regular part of the plan.
