Vivien Dettwiler – A Solar Cabin Bike You Can Sleep In

Vivien Olivier Dettwiler lives in the Tafeljura south of Basel and works on electromobility projects. “Efficiency and sufficiency are always my top priority.”

His prototype is a solar-powered pedal-electric cabin bike for daily commuting and long trips in all weather. A wide sliding door can stay open or closed while riding. With the seat folded down, the inside space of about 1.9 × 0.5 m becomes a bed, for sleeping overnight while the vehicle charges.

A Shengyi geared front hub motor, a 2.5 kWh 52 V battery of 21700 cells, 160 Wp of SunPower cells on the cabin and 640 Wp more stored in the trunk for stops. Weight: 61 kg. He rode it on The Sun Trip 2024 to the Sahara.
