We don’t offer an additional battery pack or range extender. We have looked at what the market offers and came to the conclusion that such extenders, compared to the high costs and weight, do not offer much more added value or even capacity.
Please note that our bikes ride like normal bicycles even when the battery has run out or the motor is switched off. Our focus is on producing urban e-bikes for commuting and smaller tours, and with a capacity of 336 Wh, our battery already offers a good range while keeping the bicycle weight low.
