Battery and range
The manufacturer quotes a maximum range of 100 km for the documented configuration. Documented range conditions (distances in km unless stated otherwise): Manufacturer specification range 75-100 km; load, temperature and terrain not published. This is a manufacturer claim, not an ortlux road test. Assistance level, rider and luggage weight, hills, temperature and tyre pressure affect actual range.
Fit, storage and use
- The manufacturer lists a rider-height range of 165-198 cm. Compare the frame and saddle dimensions with your fit before ordering.
- The stated vehicle weight is 26.5 kg. Consider stairs and lifting requirements, and check the weight basis below.
- For storage, compare the folded dimensions of 108*45*77 cm with your available space.
- Check the exact regional configuration and the rules for your intended route. A published maximum speed does not establish permission to use public roads.
