Description

The all-mountain steed is here to deliver fun on every trail.
The Regulator SX is our all-mountain eMTB designed to provide a nimble and responsive ride. No trail is too tame or too gnarly for the dedicated mixed-wheel platform with 150mm rear and 160mm front travel and geometry that promotes agility and playfulness. The Regulator SX will be the choice for riders looking for a chassis that excels in a variety of terrain with the added assistance of a Bosch SX drive unit delivering 55nm of torque from a 400wh battery. Coupled with our SBG geometry, you have an eMTB experience close to that of non-assisted bikes. This combination provides the best range-to-weight ratio for those who value lighter ride characteristics, giving you the best of both worlds with one of the most reliable and intuitive motor systems available on the market. For those looking for extra range, the Bosch range extender will take you up to 650wh for all day adventures.
