The 2016 Haibike sDuro Allmtn RC has been powerfully integrated with the yamaha crank drive system. Still exclusive to the Winora group (Haibike, Lapierre, Staiger, Raleigh), which makes this a pretty rare and significant drive. The yamaha signature crank drive powerfully provides 280% assistance, with a peak torque of 80nm. The innovative ' 0% cadence' ensures full output at the first stroke of the pedal, providing quite a reactive and enjoyable drive. It is also the only crank drive to offer a double chain-ring, providing you with more gears for adventure.
