Meet the Ace — P-51’s New Class 2 E-Bike

10 pounds lighter, the Ace is P-51's latest evolution in electric rides. Designed by the same crew that started with custom Sur Rons, the Ace delivers a street-legal, Class 2 experience without sacrificing a quality ride. Cruise at 20 MPH or unlock it to reach top speeds of 28–32 MPH. With dialed-in handling and a lighter frame, the Ace is made for riders who want performance, agility, and everyday versatility—all in one sleek package.

  • 750 WATT MOTOR

    Tuned specifically to the P-51's riding style, the power unit delivers 750W nominally and a 1800W peak power. The team custom-tuned this motor for maximum performance, using stainless steel gears ensuring reliability and exceptional torque.

  • STREET LEGAL

    Fully compliant with Class 2 regulations and officially classified as a bicycle, the P-51 Class 2 E-Bike lets you ride on bike paths and streets without worry.

  • SMOOTH SUSPENSION

    The suspension feels just like your favorite e-Moto, giving you that smooth, controlled ride you love. With fully adjustable front and rear suspension, you can dial in the perfect setup for any terrain—comfort and performance, all in one.
