The XPeak2 is a newly upgraded version of the trail-ready, all-terrain eBike. Tested to the most aggressive safety standards for off-road eBikes (eMTB), and named by Men's Health as a "Best of Sweat" winner in the 2025 Tech Awards, the XPeak2 now comes standard with an industry-leading torque sensor that provides an exceptional riding experience with intuitive and controlled power delivery at each pedal stroke. Combined with the 750-watt Stealth M24 motor (1310 Peak) for a powerful yet hushed motor experience, the XPeak2 delivers the muscle and speed to take on any terrain as a Class 1, 2, or 3 eBike. Additional upgrades include a newly designed hydroformed frame, a larger 203mm front disc brake rotor for maximum stopping power, an integrated color display, lock-on grips, and an 8-speed Shimano drivetrain.

This is a great E-Bike. Very good acceleration. Fun and powerful. It folds easily and was easy to assemble using just a 3 minute video. I'm very satisfied and highly recommend.
