Crossing streams is plain sailing too – with a drive unit that is well protected.

Recharging on the trailer: the batteries and other electronic devices are recharged with solar power while the eBikes are on the move.
Discussing the relative merits of eBikes and motorbikes with a Mongolian herdsman. A point that weighs heavily in favour of the eBike and solar power is that filling stations are not required.
The Bosch drive system provides badly needed power assistance. Some ascents would be impossible by muscle power alone with a heavily packed trailer.
Mountain stages of the Tour de Mongolia are a tough test for human and machine. If that’s how the terrain is, you just have to get off and push, and that’s when the push function comes in really handy.
The Kreidler cross bike is equipped with a Bosch Speed drive unit that provides pedal assistance up to a speed of 45 km/h. Without a trailer Ondra Veltrusky manages a sporting 15 km/h on steep ascents.
The on-board computer on the handlebar keeps Pedelec Adventures’ Susanne Brüsch up to date on key data of her day’s cycling: range, power assist mode, battery status, and speed are easy to read.
During the Tour de Mongolia the Bosch batteries were only charged once from a standard power socket. Solar power recharged the batteries throughout the remainder of the tour.
