The Shuttle AMP'd Ride hardwires its SRAM GX Eagle Transmission directly into the Avinox drive system, cutting the standalone derailleur battery out of the equation entirely. That connection unlocks SmoothShift, which smooths out shifts under load and lets us shift while coasting instead of pedaling through the mechanism. If the main battery runs dry, a partitioned reserve keeps the derailleur alive so shifting never stops working mid-ride. What Our Gearhead(R) Experts Are Saying:"I felt the torque before I saw the grade. On a loose, sustained climb, the Avinox motor's 130 Nm just keeps feeding power to the rear wheel without any hesitation or surge, so I stay seated and spinning instead of hunting for traction."Heads up! We do our best to keep bike specs and images current, but occasional component changes can happen without warning, and sometimes the photos might not show the exact build you'll receive.
