Scott Lumen 910

The Scott Lumen 910 is aimed at riders who want a helping hand on the climbs during cross-country, marathon or technical trail rides, but who don't want the bulk and heft that comes with a full-power electric mountain bike. Scott rates it for what it calls usage condition 3, which covers technical singletrack and drops up to 60cm rather than bike-park jumps or sustained downhill use, so it's worth being clear from the start that this is a trail and marathon bike with assistance, not a gravity machine. At a UK RRP of £7,599, you're buying a carbon-framed, 29in-wheeled bike built around the idea that an e-MTB can still feel like a proper mountain bike rather than a motorbike with pedals.

There's currently one Lumen 910 build sold in the UK, built around Scott's TQ HPR60 motor system. That simplifies the decision considerably: rather than picking between several specification levels, you're really deciding whether the HPR60 concept, light weight and moderate motor output suit the riding you actually do.

The HPR60 motor and battery, and what that means day to day

The TQ HPR60 mid-drive puts out a maximum of 60Nm of torque, which is modest next to the biggest full-power motors on the market. Scott's UK product page lists assistance up to 25km/h as the EU specification figure. That's not a huge amount of raw shove, and it's a deliberate choice: less torque and a smaller motor unit help keep the whole bike light, which matters more to a cross-country or marathon rider than outright climbing grunt does.

Power comes from a 360Wh battery built into the frame, plus a removable 160Wh range extender that's included rather than sold as an optional add-on. The extender fits at the front bottle-mount position, and together the two give a combined nominal capacity of 520Wh. In practice that means you can ride lighter and leave the extender at home for a short local loop, then bolt it on for a bigger day out, rather than always hauling around capacity you don't need. It's worth remembering that battery capacity describes energy stored, not a promised distance or riding time; how far it gets you depends heavily on terrain, assistance level and how much you lean on the motor. Charging is handled through a TQ 4A charger, and Scott's own guidance is that charging with the extender attached prioritises topping up the internal battery first. The TQ HPR display adds Bluetooth and ANT+ connectivity with smartphone app support, so you can adjust how the assistance behaves rather than being stuck with one fixed character. Scott's claimed bike weight is around 17.8kg in a tubeless setup, measured without the 1.1kg extender fitted, which is genuinely light for an assisted trail bike and goes a long way to explaining why this platform feels more like a boosted trail bike than a heavy e-MTB.

Suspension, drivetrain and brakes for technical trail riding

Up front there's a Fox 34 Rhythm Grip fork with 140mm of travel and three-position adjustment, paired with a Fox Nude 6 EVOL Trunnion shock giving 130mm at the rear. Scott's TwinLoc remote lets you flick between Lockout, Traction Control and Descend modes from the bars, so you can firm the bike right up for a fire-road climb, back off into a more supportive traction setting for technical singletrack, and open everything up for the way down, all without reaching for the shock itself. The carbon HMX frame also has an adjustable head angle, giving some scope to tune handling to taste or terrain.

Shifting comes from a wireless SRAM S1000 Eagle AXS Transmission, a 12-speed groupset with an AXS Pod controller and a 10 to 52 tooth cassette, so there's no derailleur cable to route through the frame or snag on the trail. Braking is handled by SRAM Motive Bronze four-piston callipers on 180mm HS2 rotors at both ends, which is a sensible, generously sized setup for a bike that's expected to carry speed on technical descents. Tyres are Schwalbe Wicked Will EVO TLE units in a 29 by 2.40in size, mounted tubeless-ready on Alex Rims X-30S rims, an XC-leaning tyre choice that fits the bike's cross-country and marathon brief rather than a burlier enduro tread.

Sizing, fit and weight limits

The Lumen 910 is offered in S, M, L and XL, and the published UK retailer height guidance for those sizes overlaps at the edges rather than giving one clean cut-off. A rider around 168cm, for example, sits right at the boundary between S and M, so it's worth checking the reach, stack and effective top tube figures for your height against your current bike rather than relying on the height band alone; this guidance is a retailer height guide, not an official Scott fit prescription. Scott's published maximum system weight is 130kg, but that figure covers the bike, rider, kit and luggage together rather than being a standalone rider weight limit. The fitted Syncros SP-M302-AL2 dropper post uses a 31.6mm diameter, though Scott hasn't published size-specific drop lengths, so if a particular amount of drop matters to your fit, it's a detail to look into for your specific frame size before buying.

Two Lumen 910s worth telling apart

Searches for this bike also turn up an earlier Lumen eRIDE 910 from the HPR50 generation, dated to 2023. That older bike used a 50Nm HPR50 motor along with different suspension and a different Shimano drivetrain, and any reviews or manuals written about it don't describe the motor, drivetrain or brakes on the current HPR60 Lumen 910. If you're comparing listings, the reliable way to tell them apart isn't the year printed on the page but the fitted components: the current 910 has the TQ HPR60 motor, wireless SRAM S1000 AXS Transmission and SRAM Motive Bronze brakes described above. If an offer's component list looks different from that, particularly around cockpit width or the dropper fitted, it's worth checking exactly what's specified before you commit.

Ownership: guarantee and living with the battery split

Scott's current frame and rear-end guarantee runs for five years, but only if you register as the first buyer within a year of purchase and have the bike serviced at least annually by an authorised Scott dealer with that work documented; skip the servicing and the cover drops to three years. Components themselves sit outside this guarantee. On the trail, the integrated rear shock layout is designed to leave room to carry the range extender and a bottle together, so a longer ride doesn't force a choice between extra range and having water to hand, even though any sliding bottle-mount arrangement Scott offers for that setup is an optional extra rather than something fitted as standard.
