The Riese & Muller Range Extender is a Bosch PowerMore 250Wh additional battery which supplements the power of the standard supplied battery. It provides even greater range and flexibility. Only as big as a drinking bottle and weighing just 1.6kg, it can be stowed away in a backpack or bike bag. And should you spontaneously decide to go on a longer trip, then just attach the energy reserve and continue riding for approximately another 50km without the need to stop and charge.

Only available for Riese & Muller electric bikes with this option configured at factory. Contact us if you want to discuss after-market options.
