Lightrider E Pro 2026

The Thömus Lightrider E Pro 2026 is the Swiss boutique brand's flagship lightweight all-mountain eMTB, an ultra-high-modulus carbon chassis built around the Shimano EP801 motor in a remarkably light package. Headline numbers: 160 mm fork, 150 mm rear travel, Shimano EP801 at 85 Nm and 600 W peak (2.7 kg), 800 Wh battery (non-removable, integrated), 65.4 degree head angle, reach 424 to 509 mm across four sizes, 437 mm fixed chainstay, and a class-bending 17 kg claimed weight at £9,999. The market verdict on the Lightrider platform is that Thömus has achieved one of the lightest credible 85 Nm full-power eMTBs anywhere, undercutting even the Cannondale Moterra SL (19.5 kg) by 2.5 kg through aggressive carbon engineering and a tightly integrated chassis.

Drive system and range. The Shimano EP801 at 85 Nm and 600 W peak is the current-generation Shimano full-power unit, programmable via E-Tube with AUTO and FREE SHIFT support on Di2 drivetrains. The 800 Wh integrated battery is unusually generous for a 17 kg eMTB, with most lightweight rivals fitting 320 to 600 Wh packs. Real-world range on this combination is exceptional: 50 to 80 km of mixed mountain riding depending on assist mode and elevation, which puts the Lightrider E Pro in genuinely full-day touring territory. The non-removable design is the trade-off, with battery service requiring shop-level access. The Shimano ecosystem lacks the OTA polish of Bosch Flow App or DJI Avinox but is mature and well-supported by Shimano dealers.

Geometry and handling. The 65.4 degree head angle is steeper than the modern aggressive all-mountain norm of 63 to 64 degrees, biased toward agile climbing, tight singletrack and cross-country-pace riding rather than steep descents. Reach progresses 424, 454, 479 and 509 mm across S to XL with a fixed 437 mm chainstay and wheelbase scaling 1169 to 1274 mm. The 437 mm chainstay across all sizes keeps the rear-centre snappy and the platform feels lively despite its 160/150 mm of travel.

Build and value. Single base trim at £9,999 with 17 kg claimed. Thömus operates a configurator-style sales model, with builds specced to order. Standout choice is the headline weight: 17 kg for a 160/150 mm full-power eMTB with 800 Wh battery is genuinely class-leading and represents serious engineering investment in carbon construction and component selection. Questionable for many buyers will be the £9,999 entry cost when an Amflow PL Carbon at £5,999 delivers 21 kg with 105 Nm and 800 Wh, or a Cannondale Moterra SL at £6,499 hits 19.5 kg with 85 Nm and 601 Wh, both with full dealer networks. The Lightrider E Pro is asking premium-engineering money for premium-engineering results.

Verdict. The Lightrider E Pro is in current production through Thömus Switzerland's dealer network, which is concentrated in Switzerland, Austria and Germany with select USA distribution via Thömus USA. The single curated community quote on file refers to an older Lightrider e-ultimate variant at 14.6 kg full-suspension with 540 Wh, demonstrating that Thömus has long pursued the lightest-possible-eMTB engineering brief at the highest end of the price ladder. Buy it if you want the lightest credible 85 Nm full-power eMTB with an 800 Wh battery, you appreciate boutique Swiss carbon engineering, you have £9,999 for a single platform and you accept the non-removable battery as the cost of the weight target. Look elsewhere if you need a removable battery, you want a slacker enduro-norm 64-degree-or-slacker head angle, the deepest dealer network outside Central Europe, or simply more bike for the cash at the same money. The Lightrider E Pro is a fundamentally different proposition from the value-led Cube, Bianchi, Focus or Specialized alternatives: it is the Porsche of the lightweight eMTB world, built by Swiss craft engineers for the rider who values weight reduction above all other metrics and is willing to pay accordingly. As of mid-2026 it sits at the very top of the lightweight 85 Nm class for sub-17 kg achieved without sacrificing battery capacity. For the wider eMTB community, the 65.4 degree head angle and 17 kg target make this an eMTB that should suit cross-country and rolling-trail riders far better than aggressive enduro racers, who will find their natural home elsewhere in the segment. Sizing covers S to XL with a properly small 424 mm S reach, so the bike is fittable across a real range of rider heights.
