The new Big Sur U's 750W motor delivers powerful performance with reduced noise and improved energy efficiency, giving you more range and a smoother ride. A high-precision torque sensor instantly reads your pedaling input and adjusts motor output in real time, providing seamless, natural assistance that feels perfectly in sync with every ride. Built like a tank for long-term reliability, this system responds immediately to your effort for confident, intuitive control.

When it’s time to slow down, 203mm hydraulic disc brakes deliver strong, consistent stopping power, keeping you in control on steep descents and in wet or challenging conditions.

Plus, it includes a rear seat—perfect for bringing along your best friend to the party!
