Trailfox AMP One 2025

The BMC Trailfox AMP One 2025 is a Swiss carbon enduro eMTB built around the now-discontinued Shimano STEPS E8000 motor and a 500 Wh removable battery. Headline numbers: 160 mm of fork travel, 150 mm at the rear, 70 Nm of torque, a 22.6 kg claimed weight, a 64.5 degree head angle and reach progression 433 mm on S, 458 mm on M, 483 mm on L and 508 mm on XL. Production status: discontinued. This is included on the database for legacy buyer-research purposes: BMC has refreshed its eMTB line for 2025 and beyond with newer Bosch and Shimano EP801 platforms. The community framing is reliability-aware: @ktudore's well-known Trailfox AMP motor diagnostic established the platform's most documented failure mode.

Drive system and range. The Shimano STEPS E8000 motor is two generations old: 70 Nm of torque, 250 W nominal, 2.89 kg weight, with no current firmware-update path. The E8000 was Shimano's flagship eMTB motor at the time of the Trailfox AMP One's design but has since been superseded by the EP8 (85 Nm) and EP801 (85 Nm with refined firmware and 600 W peak). The 500 Wh Shimano BT-E8036 battery is removable and on the small side by 2025 standards (rivals at 160 mm of travel routinely run 720 to 800 Wh). Real-world range from 500 Wh on E8000 in enduro use typically lands 25 to 40 km depending on assist and rider weight.

Geometry and handling. A 64.5 degree head angle is solid modern enduro, in line with mainstream rivals. Reach steps clean 433 mm on S, 458 mm on M, 483 mm on L and 508 mm on XL with a 25 mm-per-size progression. The 442 mm chainstay is held constant across all sizes and is on the short side for modern enduro, supporting a more agile, less stretched ride character. Wheelbase 1230 to 1305 mm. With 160 mm of fork and 150 mm of rear travel, this is a long-travel trail-to-enduro chassis from an era when 65 degree head angles were more aggressive than the current norm.

Build and value. BMC published the Trailfox AMP One at £8999 retail at the time, 22.6 kg, for the spec on file. The carbon frame, 160/150 mm chassis and Swiss brand pedigree justified premium pricing. @DLif's 2020 Trailfox AMP 2 documents the related platform's spec: Fox Performance 36, Fox DPX2 rear, Magura M5 brakes 203 mm and SRAM NX 1x12. @KTMJack confirms the carbon weight at approximately 50 lbs (22.7 kg) for the platform.

Community-verified strengths. Three things owners praise. The Swiss carbon chassis quality is genuinely high and ages well. The 64.5 degree head angle and modern reach progression remain valid by 2025 standards: the chassis itself has not been outclassed. And the Trailfox AMP One was BMC's premium build with proper Fox 36, Magura brakes and a sensible component package: at second-hand 2020-era prices (around $3450 USD per @DLif's sale listing), the platform offers genuine value for buyers willing to overlook the motor generation.

Caveats and known gripes. Three honest flags. The Shimano STEPS E8000 motor has a well-documented plastic-gear failure mode. @ktudore details a Trailfox AMP motor that stopped working with a grinding sound and zero assist, traced to a snapped plastic cog connecting the cranks to the clutch. @Martin Sadecký and @jam2918 document the now-available aftermarket replacement gear path: Shimano does not supply this gear as a spare part, so a complete motor replacement is the official fix. @Taoplus reports periodic assistance dropout on the related DU-E7000 sibling, requiring a backward pedal to unlock. The 500 Wh battery is small. Production is discontinued, so future-proof support is via second-hand parts.

Verdict. The BMC Trailfox AMP One 2025 is for the second-hand buyer who finds a discounted Trailfox AMP and wants a properly-engineered Swiss carbon enduro chassis with modern 64.5 degree geometry, and is happy to live with the older Shimano E8000 motor's known plastic-gear failure mode (and the aftermarket fix that resolves it). Production is discontinued. If buying new, look at the latest BMC Trailfox AMP variants with newer motors, or rivals like the Cannondale Moterra LT, Cube Stereo Hybrid 160 or Canyon Torque:ON.
