Mobile – whatever your age

Physically active but with a flexible electrical assist — particularly when travelling uphill. The Bio‑Hybrid DUO brings seniors the comforts of an electric bike, but it comes with other benefits too: there’s no risk of toppling over thanks to the enhanced driving stability afforded by four wheels, with ergonomically low entry, and comfortable seating for two people. Mobility for two well into older age.
