Steamer Pmax
The Steamer Pmax is the perfect companion for unforgettable trail adventures. High-speed descents with tricky passages and fast-paced trail climbs are its core disciplines. But even in moderate terrain, the plush suspension setup spoils you with plenty of comfort and safety. The Bosch drive unit with up to 1,125 Wh provides the necessary propulsion – enough power for several mountain peaks in a row!







Details
Simply get on and conquer multiple summits on one tour! For ambitious trail bikers who like to benefit from electric support, there is no way around the Steamer Pmax. Thanks to its enduro capabilities, it doesn't shy away from even the most challenging trails. Riders can conserve valuable energy by relying on the support of the latest-version Bosch Performance Line CX. The drive unit is housed in the sturdy aluminium frame, which offers reliable, robust protection against damage from external influences.
The model is available either with 29-inch wheels or as a Mullet version with a 27.5-inch rear wheel and a 29-inch front wheel. As with the wheels, there are also two colour options to choose from.
Features
The geometry of the Steamer Pmax can be adapted to the respective wheel size by means of a Flip Chip. Riders can select between a suspension travel of 150 mm and 170 mm.
The low-positioned seat and top tube and the long Vario posts offer maximum freedom of movement. Behind the seat tube, there’s enough space in the Storage Box for a spare inner tube, tools and more.
Thanks to the Double Bearing technology at the main bearing points, the bike boasts increased stiffness and durability.
A 220 mm diameter disc brake can be mounted on the rear wheel.

Technology
Thanks to Advanced Internal Cable Routing, all cables are routed internally through the frame, which gives the bike a clean look and protects the cables. For more stiffness at the main bearing, Double Bearing technology is used. Another core element is the hydroformed aluminium frame, in which the battery is beautifully and safely housed. The Rock Guard made of impact-resistant ABS plastic protects the drive unit from damage caused by rocks and dirt.
