Trek Powerfly+ 6 Gen 5 review

Where the Powerfly+ 6 Gen 5 fits

The clearest match is long forest, moorland and mixed-terrain rides where battery margin and dependable mechanical parts matter. 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

The accessible Evans listing does not identify the motor precisely. It describes the controls as Bosch Purion 200.

Bosch Performance Line CX provides confident full-power support on steep and loose climbs. The motor is shared with the cheaper Powerfly+ 4, so the premium sits in capacity and control components.

Twelve-speed gearing helps the rider maintain efficient cadence, while the stronger brakes better match the speed and mass enabled by the drive system.

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

The removable 800Wh battery is the headline advantage, giving more energy margin than the 600Wh Powerfly+ 4 variants.

It adds weight and charging time, and capacity alone cannot promise a particular distance. Cold, soft terrain and high assistance remain significant variables.

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 Alpha Platinum Aluminium, Removable Integrated Battery (RIB 2.0), tapered head tube, guided internal routing, Control Freak internal routing, Motor Armour, Boost148, 12 mm thru axle. Fork and suspension details are RockShox Recon Silver RL, Solo Air, Motion Control damper, lockout, tapered steerer, 42 mm offset, Boost110, 15 mm Maxle Stealth, 120 mm travel. The exact tyres should be confirmed on the selected build.

The Recon 120mm fork is a meaningful upgrade over the Suntour on the 4, and Shimano four-piston brakes improve confidence on prolonged or steeper descents.

Wide 29in tyres and hardtail efficiency suit covering ground, but the rigid rear still transmits repeated impacts. Rail+ is the better tool for enduro terrain.

Brakes, transmission and everyday equipment

The bike uses Shimano 4-piston hydraulic disc, MT4100 lever, MT420 calliper. Transmission is Shimano Deore M6100, 12-speed; Shimano XT M8100, long cage; Shimano Deore M6100, 10-51, 12-speed. The equipment information is Bontrager Line Dropper, 170 mm travel, MaxFlow, internal routing, 31.6 mm, 450 mm length.

Deore 12-speed with an XT rear derailleur is widely serviceable and avoids wireless batteries. Trek’s mount provision keeps touring and utility options open.

The 800Wh bike is substantial to lift, and trail use will consume tyres, brake pads and drivetrains. A suitable e-bike-rated car rack may be required.

What the published evidence tells us

Evans listed this build at £2,679 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.

The exact 800Wh, Recon and Shimano build is documented by Evans and Trek.

Independent current Powerfly testing supports refined Bosch behaviour and capable mixed-terrain use, but this particular hardtail trim was not the test bike. No hands-on component claims are invented.

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 removable 800Wh battery
• Advantage: Recon air fork
• Advantage: Shimano four-piston brakes
• Advantage: Reliable Deore/XT 12-speed mix
• Disadvantage: Heavier than 600Wh versions
• Disadvantage: Still a hardtail on repeated rough impacts
• Disadvantage: Same motor as the cheaper 4
• Disadvantage: More bike than short urban journeys require

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 Powerfly+ hardtail sweet spot for serious distance: range and control upgrades are tangible, while the mechanical build stays serviceable.
