The 48 V SyncDrive Pro 4 system delivers sustained 120 Nm support and 850 W peak power for steep, technical climbs. Zero-cadence torque-based response engages in just 0.28 seconds, giving you immediate support to restart and maintain momentum from low-speed situations. Synchronized Power Matrix reads rider and bike inputs to deliver support that feels connected and intuitive, while Traction Control detects rear-wheel slip and refines motor support to help you regain grip when climbs get steep and loose.

The EnergyPak Smart 560X packs 560 Wh of full-power capacity into a compact 2.6 kg battery, with a lifespan of up to 2,300 cycles for long-term reliability. Its high-density 352 Wh/L design allows the battery to integrate cleanly into the frame, helping the bike feel easier to move, quicker to respond, and more natural underneath you when the trail gets tight or technical. Add the compatible 280 Wh EnergyPak Plus range extender for up to 840 Wh total capacity—so you can go light or go long.

Full Maestro suspension kinematics are preserved through a custom motor housing, keeping the rear wheel active for pedaling stability, traction, and control over rough terrain. With 150mm rear travel, a 160mm fork, MX wheels, a 3-position flip chip, and a 20.0 kg complete bike weight, the chassis stays composed and easier to place through technical climbs, tight corners, and demanding descents. To handle the added forces of full-power riding, TRX and TRA HD WheelSystems use high-torque titanium ratchet hubs that are 20% stronger in fatigue testing and the 300 Nm-rated high-torque KMC chain delivers 35% greater pin strength versus leading benchmark 12-speed chains.
