The short version

  • Best for enduro buyers who want the Eagle 70 and Lyrik version of the carbon Rail+ and will verify the motor and final model code with Evans
  • Confirm the exact motor and UK assistance configuration
  • Bosch PowerTube 800 Wh, smart system
  • Main trade-off: Motor specification is absent
01

Where the Rail+ 9.7 Gen 5 Eagle 70 fits

The clearest match is enduro buyers who want the Eagle 70 and Lyrik version of the carbon Rail+ and will verify the motor and final model code with Evans. 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. The exact motor, display and control configuration should be established before purchase.

No motor model or torque was captured for product 707675, so this analysis does not assume Bosch CX merely because current Rail+ models use it.

Ask for the Trek model code, motor generation, legal assistance limit, controller and software compatibility. Those details materially affect performance and service.

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 Evans data does identify an 800Wh Bosch PowerTube battery, providing a credible capacity reference but not a complete electrical-system match.

Confirm that the battery is removable, which charger is supplied and whether the pack is covered as new stock. Range still cannot be promised from capacity alone.

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 OCLV Mountain Carbon, Removable Integrated Battery (RIB 2.0), tapered head tube, guided internal routing, Motor Armor, angle-adjust headset, Mino Link adjustable geometry, adjustable leverage rate, 34.9 mm seat tube, ABP, UDH Boost148, 12 mm thru axle, 160 mm travel. Fork and suspension details are RockShox Lyrik, Delta RC, DebonAir+, tapered steerer, 44 mm offset, Boost 110, 15 mm Maxle Stealth, 160 mm travel. The tyres are Bontrager Brevard Pro XR, Tubeless Ready, dual compound, aramid bead, 60 tpi, S: 27.5x2.50, M-XL: 29x2.50.

An OCLV carbon 160mm chassis, Lyrik fork and Eagle 70 Transmission indicate serious all-mountain intent. The accessible listing identifies the brakes and wheel equipment, but the missing motor detail prevents a complete platform comparison.

This is not the same build as Evans’ SLX/XT Rail+ 9.7, which uses a Zeb fork and different component package. The drivetrain name, rather than a model-year label, is the clearest way to keep the two current listings distinct.

Brakes, transmission and everyday equipment

The bike uses Shimano MT620 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 Elite Dropper.

Mechanical Eagle 70 avoids derailleur battery management, while an 800Wh enduro bike remains heavy and expensive to transport and maintain.

Warranty commencement, spare parts, the exact motor generation and the final model code all need written confirmation because the retailer record is incomplete.

What the published evidence tells us

Evans listed this build at £5,500 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 live Evans record supports the named frame, 800Wh battery, drivetrain, brakes and selected components. Trek’s Rail+ range page establishes family context but does not verify the missing motor field for this exact Eagle 70 listing.

Independent Gen 5 Rail+ reviews cover other component builds. They provide platform context only and cannot close the electrical-specification gap.

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: Carbon 160mm platform
  • Advantage: 800Wh stated capacity
  • Advantage: Lyrik fork indicates serious trail intent
  • Advantage: Mechanical Eagle 70 Transmission
  • Disadvantage: Motor specification is absent
  • Disadvantage: Exact model code needs confirmation
  • Disadvantage: Heavy and specialist to transport
  • Disadvantage: Independent tests cover other Rail+ builds
08

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.

Potentially attractive, but too incompletely documented for a responsible recommendation until Evans supplies the final model code and electrical specification.
