A New Breed of Power.

Fine-tuned by our team of software experts, our Algorhythm software calculates the power needed by the drive system and delivers optimal performance as required.

A Powerful Motor for Robust Performance.

The PSA1 uses a small leading gear set motor, which has the gear set located on the inside. Even though it is light in weight, the PSA1’s motor has been specially designed to deliver robust power, with less than 20 percent of the power lost during use. It is also one of the quietest motors in the e-bike industry.

Advanced Removable Battery.

The PSA1’s highly dependable and long-lasting LG battery delivers as much as 95 kilometers of power-assistance on a full 6-hour charge. The removable battery makes charging especially easy and convenient, anytime and anywhere.

Maximum riding distance is measured by 75kg weight rider, with mode 1 assistance power, 60RPM pedal cadence and 25km/h constant speed on paved road. The distance may be different depends on rider weight, derailleur select, speed, cadence, battery status, tire pressure, road and weather condition.

A Revolutionary Independent Saddle Design.

The PSA1’s aluminum frame and independent saddle design transforms the traditional triangle-shaped bike design and supports up to 120 kilograms.
