PS1 Advance (Carbon Frame)

$ 2,499.00

Sleek. Stylish. Smart.

The new BESV PS1 Advance pedal-assisted electric bicycle is all of these things, and more. Extremely lightweight, the Panther is the perfect choice for urban riders, with our advanced proprietary Algorhythm power drive system ensuring the smoothest of rides, for daily commutes and fun rides around town.

Advanced Frames Crafted with an Artist's Touch

The PS1 Advance carbon frame employs more than 10 layers of carbon fiber, delivering a lighter but stiffer frame. Completely handmade and constructed in one piece, the PS1’s carbon frame not only meets EN14764 testing certification, but at a total weight of only 38.5 pounds, it is the lightest commuter e-bike in the world today!

Power Your Ride the Smart Way

Smart Mode calculates the level of assistance you need for optimal ride comfort, taking into account both riding conditions and your pedaling power, and intelligently adjusts the power while you ride.

A New Breed of Power

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

A Powerful Motor for Full-Throttle Performance

The PS1 Advance uses a leading gear set motor. This type of motor is smaller, with the gear set located on the inside. Although it is lighter, the PS1’s motor has been specifically designed to deliver robust power, with less than 20 percent of the power lost during use. In addition, the PS1 Advance has one of the quietest motors in the e-bike industry.

Charge Up Your Ride with an Advanced Battery

The PS1 Advance features a premium Sony® battery. Highly dependable and long-lasting, the PS1’s battery delivers as much as 40 miles of power-assistance on a full 4-hour charge.

A Revolutionary Independent Saddle Design

The PS1 Advance’s carbon-fiber frame and independent saddle design transforms traditional triangle-shaped bike design and supports up to 220 pounds.
