BMC Roadmachine AMP reshapes road e-bikes for performance, adapting popular carbon endurance road bike with lightweight Mahle X20 powertrain!
. All the same signature angular BMC aero tube shaping is there, only the downtube is a bit bigger in diameter – but really not by much.
The Mahle X20 system gives a standard 250W pedal assist, with a max rear-wheel torque comparable to 55Nm from a mid-drive motor. With a 350Wh battery, BMC claims riders can get up to 140km distance or 3000m climbing support in the most Eco mode. But you can also add Mahle’s new optional 173Wh Range Extender external battery to go 50% further. It is smaller, lighter & much cheaper than the extender I used with their. But that also means it can use a regular heavy-duty bottle cage instead of something proprietary.
The e-bikes feature conventional modular internal cable routing that enters through a port in the downtube – not fully internal.
