Product Details
The BMC Fourstroke AMP LT TWO is a down-country e-bike that’s not afraid to do things differently from the rest. With forward-thinking design and component choices, it’s sure to please those looking for something unique. This 120mm travel (front/rear) down-country machine is built to handle a variety of terrains and riding styles, from technical trails to smooth cross-country routes.
At the heart of the Fourstroke AMP LT TWO is the TQ-HPR50 system, a groundbreaking drive unit that combines power, lightness, and near-silent operation. Integrated seamlessly into the frame, the TQ-HPR50 system features a harmonic pin-ring transmission, a 360 WH battery, and a 2” fully integrated display. A minimalistic handlebar remote adds to the sleek design, offering effortless control. This system is the lightest e-bike drive unit in its class, ensuring you get the performance you need without extra weight.
The geometry of the Fourstroke AMP LT TWO is where this bike truly sets itself apart. With a 66.5˚ head angle, it pushes the boundaries of traditional cross-country design, offering enhanced stability and confidence on steep descents. The bottom bracket height has been lowered by 9mm from the previous version, which improves stability further. The 77˚ seat angle provides excellent pedaling efficiency, making it a standout choice for technical climbs and fast descents.
Traction is crucial for faster times, and the updated APS Suspension System delivers. With next-level kinematics and best-in-class suspension performance, small bump sensitivity is significantly improved, giving you the edge on rough and loose climbs. The decreasing anti-squat curve further enhances traction and control.
BMC has also considered practical details with the Fourstroke. Two 21oz bottles can fit on the top side of the downtube, one of which can be used for a range extender if needed. A bump stop is included to prevent the fork from damaging the frame. Fully-guided cable routing ensures smooth and reliable operation, going through the front triangle, lower link, and rear triangle to the brake caliper or derailleur.
Ideal for those who spend long days in the mountains and seek to push their limits, the BMC Fourstroke AMP LT TWO is designed for riders who demand the utmost from their short travel bike. Ready for adventure, it promises to deliver exceptional performance on every ride.
