Trek Checkpoint+ SL 5 review

Where the Checkpoint+ SL 5 fits

The clearest match is gravel riders who want quiet, natural assistance and carbon-frame comfort while preferring mechanical gearing and a simpler, lower-cost build. 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 HPR60 supplies up to 60Nm and 350W peak while remaining compact and visually discreet. Independent Checkpoint+ coverage describes the support as quiet and harmonious, with a stronger shove at lower cadence than the older HPR50 but still a closer match to gravel pedalling than to a full-power mountain-bike motor.

That restrained character is a benefit on loose surfaces and above the assistance cut-off, but it will not flatten very steep loaded climbs in the manner of a high-torque system. The GRX 10-51T cassette gives the rider a properly low mechanical gear for those moments.

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 360 Wh. Up to 50 miles (80 km) on the internal battery, or up to 90 miles (145 km) with the optional range extender.

The 360Wh internal battery helps preserve the bike's slim profile and relatively low weight. Trek references up to roughly 80km in favourable Eco-mode conditions, while independent coverage correctly stresses that luggage, climbing, wind, temperature and assistance choice can reduce that figure materially.

A compatible 160Wh range extender is the logical addition for multi-day or unusually hilly routes, but it occupies mounting space and adds cost. Riders should plan charging and luggage around their own route rather than treating the headline range as guaranteed.

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 500 Series OCLV Carbon, TQ drive system, IsoSpeed, hidden mudguard mounts, rack mounts, integrated frame bag mounts, invisible cable routing, flat-mount disc, integrated chainkeeper, UDH, 142x12 mm chamfered thru axle. Fork and suspension details are Checkpoint full carbon, tapered carbon steerer, mudguard mounts, triple rack mounts, flat-mount disc, 12x100 mm chamfered thru axle. The tyres are Bontrager Girona Pro, Tubeless Ready, GR puncture protection, aramid bead, 60 tpi, 700x42 mm.

A 500 Series OCLV carbon frame, rear IsoSpeed and 42mm Girona tyres target long-distance stability and vibration control. The rigid carbon fork keeps steering direct and provides mounting options, making the SL 5 the more conventional gravel-bike experience within this three-bike group.

Independent Checkpoint+ reports praise its unobtrusive assistance and stable adventure geometry. The trade-off is that sharp rocks and repeated corrugations reach the rider more directly than on the SL 7's 40mm suspension fork, although tyre pressure and a tubeless setup can materially tune comfort.

Brakes, transmission and everyday equipment

The accessible listing does not identify the brakes precisely. Transmission is Shimano GRX RX820, 12-speed; Shimano GRX RX822, 51T max cog; Shimano XT M8200, 10-51, 12-speed. The equipment information is Bontrager carbon, 27.2 mm, 8 mm offset, 330 mm length.

Rack, mudguard, frame-bag and fork mounts make the chassis useful beyond fast day rides, while mechanical GRX is familiar to many workshops and avoids derailleur batteries. The tubeless-ready Paradigm wheels and puncture-protected tyres are sensible starting equipment for mixed-surface use.

The battery is integrated and the range extender competes with bottle or cargo space, so a loaded setup should be mocked up before committing. The exact brake caliper specification is not clear in the parsed Evans data, which lists CL800 rotors; buyers should verify the complete brake build.

What the published evidence tells us

Evans listed this build at £4,049–£4,500 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.

Trek's live UK page and Evans support the exact SL 5 specification. Independent Checkpoint+ family articles and early ride reports support the natural motor, stable geometry and limited-but-expandable battery themes, but long-term exact-build testing remains limited.

This profile does not claim RideIn has ridden the bike. Range figures are manufacturer estimates contextualised by independent commentary, and component-level conclusions are based on specification rather than durability testing.

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: Quiet, natural and compact TQ HPR60 motor
• Advantage: Carbon frame with IsoSpeed and extensive luggage mounts
• Advantage: Wide-range mechanical GRX drivetrain
• Advantage: Simpler and less expensive than the AXS builds
• Disadvantage: Modest 360Wh battery for long loaded or mountainous routes
• Disadvantage: Rigid fork gives less impact isolation than the SL 7
• Disadvantage: Integrated battery and range extender affect charging and cargo planning
• Disadvantage: Exact brake caliper detail should be confirmed

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 rational Checkpoint+ for riders who want the excellent shared frame and drive system without paying for electronic shifting, especially when reliability and mounting flexibility outrank maximum rough-ground comfort.
