Fourstroke AMP LT

Do more. Of everything.

Do more. Of everything.

A performance XC bike that just happens to be an e-bike. Taking the character of the Fourstroke LT, but adding support courtesy of TQ’s class-leading, lightweight and near silent drive system, the Fourstroke AMP LT has a natural ride feel that amplifies your inputs rather than overwhelms them.

Elegant integration means that it looks as good as it rides. With 120mm of travel, a full-carbon frame and modern geometry it’s everything you’d expect from a BMC, just with more.

Ride more

A drive system should enhance ride feel rather than alter it entirely. With a class-leading drive unit, lightweight battery and intuitive controls, the Fourstroke AMP LT rides like a supercharged XC bike rather than a traditional e-bike.

Seamless integration

State of the art carbon construction meets cutting-edge technology. The Fourstroke AMP LT seamlessly integrates the drive-unit, battery and display into the frame to retain the svelte dynamic profile of the Fourstroke range on the outside with powerful performance on the inside.

Drive Unit

Using TQ’s pioneering Harmonic Pin-Ring Transmission the HPR50’s drive-unit is compact, light, virtually silent and delivers 50 Nm of torque. A clear display and discrete remote put information and power at your fingertips, as well as your cranks.


The TQ 360 Wh battery packs enough power for long rides while also being the lightest in its class. Fully chargeable in 2-3 hours it can be ready to go again when you are.

Range Extender

A 160 Wh range-extending battery slots neatly into the bottle cage, giving scope for even longer rides.
