A solid all-round descender (66° head angle, 150mm) — capable in the rough and steep without being an all-out bruiser.
Lightrider E1 2022
How current the bike is — newer chassis, motor and battery score higher. 10 = brand-new, 0 = legacy.

The Lightrider E1 was Thömus's original full-power eMTB: a full carbon 150 mm trail and enduro machine built around the Shimano STEPS E8000 motor (70 Nm, 250 W nominal) with a removable 504 Wh Shimano BT-E8020 battery hidden in the down tube. Sold direct in Switzerland through the Thömus configurator, the 2022 catalogue listed five base builds (TIC SLX, TIC XT, TIC XT Di2, TIC XTR and TIC XTR Di2) from CHF 5'490, each freely customisable, with 130 mm or 150 mm travel and 27.5in-plus or 29in wheel choices documented at launch. It was never officially sold in the UK, so no GBP pricing exists.
The geometry is agile rather than long and slack: 440 mm chainstays across all three sizes (S, M, L), a head angle of 66.9 degrees in the Trail setting or 66.0 degrees in the All Mountain setting, and reach from 411 mm to 479 mm depending on size and configuration. Swiss and German launch-era tests highlighted the balanced handling, the clean full-carbon frame with internal cabling, and the low weight for a full-power bike of its era, with launch-era press quoting claimed weights of 18.5 to 18.6 kg for the top XTR Di2 configuration.
By 2022 the E1 was the last of its generation. The platform dated back to late 2016, the EP8-powered Lightrider E2 had taken over as Thömus's mainstream full-power eMTB, and the E1 disappeared from the line-up during 2022, with the range subsequently led by the E2 family and the lightweight Lightrider E Ultimate. There is no owner history for this bike on the forum, so no community reliability data exists; this assessment is based on archived manufacturer pages and launch-era Swiss and German press tests.
What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.
A fair bit of pop, but happiest on flowing trail rather than trials moves.
Not enough geometry on record to judge size balance.
A workmanlike climber — expect to put in more rider effort on the steep stuff. 250W of peak power and 70Nm of torque.
No single standout trait — a balanced, versatile bike.
Lower torque or a slacker seat angle — fine, just don't expect a winch.
