Until now, the name of the Haibike bike described which motor was installed: The Xduro had Bosch units, the Sduro Yamaha units. For the new season, the Schweinfurt-based company is pursuing a new philosophy: the Xduro has a modern, stretched geometry for sporty use, while the Sduro remains more conservative and comfortable. Both motors are used in both models.
Used here Haibike the new and patent-pending "Modular Rail System" (MRS for short). This allows, in addition to the internal Bosch Powertube batteryto use an external battery. This results in a total battery capacity of 1000 Wh (or 1 kWh). Unfortunately, the range extender is only available for hardtails because the external battery collides with the shock on fullys.
All Xduros with internal Powertube battery are new developments: No frame has been taken over. Haibike still uses the current kit for frame parts such as the interface and rear triangle, but the down tube (continuous casting-hydroforming hybrid), top tube (hydroforming) and head tube are both newly designed and proportioned.
Haibike has also completely revised the geometries and adapted the Xduro fullys with Bosch Powertube to the Xduro fullys with Yamaha PW-X (formerly SDURO EVO): All fullys now have a seat angle of 75 degrees. The developers have also flattened the head angle, lowered the bottom bracket and increased the length of the top tube. This new geometry should ensure a smoother ride and a more stretched riding position than before.
The Yamaha PW-E motor sits between the old PW and the current PW-X. It is designed to support up to 110 revolutions per minute and deliver 70 Nm. The 3.5-kilo unit can be recognised by the red lettering.
