Built-in anti-theft protection for when the bike is parked, the R525 is engineered to do more than power your bike — it delivers dependable performance that gets you to your destination with confidence and peace of mind, and keeps your bike secure once you arrive.
The R525 combines built-in anti-theft protection and patented anti-lock safety technology directly within the hub motor. Anti theft protection : When the bike is parked and "Locked" (via an app or display), the controller can short the motor phases. This creates extreme electromagnetic resistance. Patented Anti-Lock Technology : Even in the event of a system error or incorrect command, the R525 ensures the wheel never locks up unexpectedly when riding.
A reinforced stator and rotor architecture provides stronger torque-bearing capability than typical 250W/350W hub motors, improving hill-climbing performance and durability under heavy loads. Combined with IPX6 protection, the R525 is engineered for reliable performance in intensive daily use, from urban commuting to demanding utility and delivery applications.
Designed with compatibility at its core, the R525 can be controlled by a wide range of smart e-bike controllers. This enables seamless integration into modern connected e-bike ecosystems and fleet management.
