- Niche Mobility unveiled the ADTS (Automatic Digital Transmission System), a pedal-by-wire prototype that replaces traditional gearing with a fully digital drivetrain
- Pedaling powers a generator inside the motor unit, which feeds electricity to a second motor driving the wheel — meaning pedaling does nothing if the system is off or the battery is dead
- Performance targets include approximately 120 Nm of torque, 80–90 km of range, and a 25 km/h assist cap for standard markets, with a 45 km/h speed pedelec version planned for the US
- The system continuously adjusts its digital "gear ratio" based on speed, cadence, and terrain, with riders choosing between modes like Easy, Flow, or Sweat in a set-it-and-forget-it experience
- The electronic architecture enables regenerative braking (active and passive when coasting downhill) plus a reverse mode — useful for backing heavy cargo e-bikes into parking spots
- Niche Mobility is targeting urban, trekking, and cargo e-bike segments, while Electrek flagged the key tradeoff: converting human power into electricity and back introduces efficiency losses versus a direct chain drive
Why it matters: For cargo and urban e-bike buyers who prioritize low maintenance and effortless riding over mechanical purity, the ADTS could remove gear-shifting complexity entirely — but the architecture means a dead battery renders the bike unrideable, and round-trip electrical conversion from pedal to wheel costs efficiency versus a direct chain drive.
