Summary

The BMC Roadmachine is celebrated for its smooth ride and excellent handling, blending the agility of a race bike with the comfort of an endurance machine. Its MAHLE X20 motor system is praised for smooth, intelligent power assistance, though some note a firm ride on rough surfaces.

  • Excellent handling

  • Intelligent power assistance from MAHLE X20 motor

  • Blend of race bike agility and endurance comfort

  • High stiffness levels for enhanced performance

Cons
  • Firm ride on rough surfaces

BMC Roadmachine AMP ONE 2023 e-road bike first ride review: universal racer with extra oomph?

Nov 2022 · Martin Staffa

The BMC Roadmachine AMP ONE 2023 is supposed to be no different from its analogue sibling, just packed with extra power. But does the rear-wheel drive on the e-road bike really only weigh in on the scales?

Highs
  • Harmonious design language and proportions

  • Easy rear wheel removal

  • Smooth but powerful support from the MAHLE motor

Lows
  • Cable routing

  • Riding position is too stretched, tires too narrow - thus little comfort

  • Colour combination of tan-wall tires and paintwork not quite coherent
