Send your rides to new heights with a full-assist e-MTB built to rip down the trails less travelled – Rail+.
This long-travel, high-powered electric enduro mountain bike packs in a massive boost, so you can tackle far-off adventures that wait just beyond the limit of what you used to think was possible.
Burly trails riddled with roots and boulder fields? The Rail+ gobbles them up with 160/160 mm of trail-smoothing travel. Ripping into the weekend with a peak-to-peak that stretches far beyond where leg days can carry you? With 85 Nm of torque and a massive 800 Wh battery, the Rail+ is built to take you there.
The new PowerTube battery from Bosch packs 800 Wh of support into the Rail+ for exploring beyond the beyond. Want to save more weight for more nimble handling? The Rail+ is also compatible with the smaller 600 Wh battery.
