TORQUE SENSING PEDAL ASSIST
World class torque sensing pedal assist - because an electric bike is only as good as it’s power distribution.
Precision torque sensing performance at 104 cadence pulses per revolution; 1,000 torque samples per second.
Sunny Day’s incredibly smooth torque sensor knows how hard you’re pedaling down to the microsecond and matches it with proportionate power.
Custom drop out design delivers whisper smooth assist at any level.
POWERFUL 500W MOTOR
BAFANG 48V 500W electric motor purpose built for speed and power. Enjoy the quiet and consistent power distribution at any speed.
