Joining the three-model analog BMC Fourstroke family introduced last week , the new Fourstroke AMP LT is the motorized eMTB version. It has the same 120mm travel front and rear as the standard LT model, shares 95% of its geometry, but tweaks the APS suspension slightly to make room for the whisper quiet TQ-HPR50 motor. At a glance, you’d be hard pressed to tell this is an e-bike. The downtube houses the battery, but they made it as slim as possible while still fitting fully sleeved cable, hose, and wire guides running alongside the battery.

The geometry has the same 66.5º head angle, with a 40mm BB drop and 170mm cranks. Chainstay length is just 3mm longer, and the larger frame sizes will have slightly shorter reach figures.

The motor is tiny, and has a narrow Q-factor, so it feels and pedals like a regular bike.

Basically, the Fourstroke AMP LT rides every bit as nimble and capable as the pedal-powered version, but with enough assist to make those big days a little bigger.

Like the regular LT, the AMP LT gets 120mm front and rear wheel travel. And it keeps the five bottle bosses in the downtube, letting you run two bottles inside the front triangle on all frame sizes!

The lightweight frame, motor, and build mean they can use lightweight suspension. Inline rear shocks are paired with Rockshox SID or Fox 34 Stepcast forks.

The AMP frames get the same notched top tubes, creating space above the upper shock mount for remote lockout […]
