Trek Fuel+ EX 8 review

Where the Fuel+ EX 8 fits

The clearest match is frequent trail riders who want the HPR60 Fuel+ with suspension and transmission ready for technical use from day one. 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 TQ LED display with Bluetooth & ANT+ connectivity.

TQ’s 60Nm HPR60 provides stronger low-rev assistance than the previous HPR50 while staying quieter and less forceful than a full-power e-MTB drive.

That measured delivery supports traction and conventional trail-bike timing. Buyers seeking maximum uplift speed should compare a Bosch CX Rail+ rather than assuming every 60Nm system serves the same purpose.

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 TQ 580 Wh. No numerical range is stated in the accessible listing; route, rider, weather and assistance level materially affect distance

The 580Wh internal pack is generous for a mid-power bike and materially extends the scope beyond the 360Wh Fuel EXe 8 XT.

It also increases system mass and charging time. Route, elevation, rider input and mode remain decisive, so even this larger pack should not be sold on a universal mileage figure.

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 NEXT Platinum aluminium, removable battery, ZS headset, adjustable leverage rate, guided internal routing, interchangeable alloy rocker link, interchangeable lower shock mount, downtube guard, shuttle guard, ABP, UDH, Boost148, adaptable travel 145 mm-160 mm. Fork and suspension details are Fox Rhythm 36, Float EVOL air spring, GRIP damper, tapered steerer, 44 mm offset, Boost110, 15 mm Kabolt X axle, 150 mm travel; Fox Performance Float X, 2-position damper, 205 mm x 60 mm. The tyres are Bontrager Brevard Pro XR, Tubeless Ready, dual compound, aramid bead, 60 tpi, 29x2.50.

A 150mm Fox Rhythm 36 and Float X shock are a clear performance step over the EX 5’s Recon-led package, adding chassis support for rougher, faster trails.

SRAM Eagle 70 T-Type is designed for robust mechanical shifting under e-bike loads, while DB8 four-piston brakes and 2.5in Brevard Pro tyres complete a purposeful trail build.

Brakes, transmission and everyday equipment

The bike uses SRAM DB 8 4-piston hydraulic disc. Transmission is SRAM Eagle 70, 12-speed; SRAM Eagle 70, T-Type; SRAM Eagle XS-1270, T-Type,10-52, 12-speed. The equipment information is Bontrager Line Dropper, MaxFlow, internal routing, 34.9 mm.

Mechanical Transmission avoids batteries in the derailleur while retaining SRAM’s full-mount architecture. Wear parts and the TQ system still make competent workshop support valuable.

This build is less likely to demand an immediate fork upgrade than the EX 5. Its extra cost is justified mainly by parts riders can feel and tune, not a different motor or frame.

What the published evidence tells us

Evans listed this build at £4,049–£4,499 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 Trek establish the exact EX 8 component level and shared HPR60/580Wh platform.

Pinkbike’s independent Fuel+ EX review supports the platform’s quiet assistance, broad range and friendly handling, but the tested trim was not this exact EX 8. We do not transfer component-specific conclusions across builds.

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: Capable Fox 36 and Float X suspension
• Advantage: 580Wh mid-power range reserve
• Advantage: Robust mechanical Eagle 70 Transmission
• Advantage: Balanced, adaptable trail platform
• Disadvantage: Costs more without adding motor or battery capacity
• Disadvantage: Still heavier than the older light-assist EXe concept
• Disadvantage: DB8 brakes are functional rather than premium
• Disadvantage: 60Nm will not satisfy every full-power buyer

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 strongest all-round Fuel+ value for riders who will exploit the better suspension, delivering the platform’s main benefits without an obvious early upgrade target.
