Silver Medal — iENA 2023, Nuremberg
The e-bike that charges itself.
SOLARIDE builds solar cells directly into the wheels. Ride it, park it, leave it in the sun — it keeps filling its own battery. Up to 50 km a day of range from daylight alone.

Technology
The wheel is the solar panel.
Every other e-bike waits at a wall socket. Ours generates while it stands, and while it moves. The panels sit inside the rim, where there is space nobody was using.
- 01
Solar cells inside the rim
Rigid panels are mounted in the open area between hub and rim on both wheels — surface that every bicycle already carries and nobody had used before.
- 02
Charges while you ride
Generated power feeds the 36 V pack directly through the controller. No cable, no dock, no stopping to plug in at the end of a trip.
- 03
Summer and winter
The cells work on diffuse daylight, not only direct sun, so the bike keeps topping itself up on overcast days and through the cold months.
- 04
Built for real roads
The panel assembly is engineered to take vibration, impact and weather — the loads a bicycle wheel actually meets, not laboratory conditions.
- 05
Folds in seconds
A 26-inch folding frame with full suspension. It goes in a car boot, up a staircase, and under a desk without asking for a garage.
- 06
Protected in Germany
The solar wheel is a registered German utility model, Gebrauchsmuster No. 20 2023 002 003, filed in September 2023 and entered on the register in July 2024.
