Tributary GRX 600 lets you see more, carry more, and experience more, all in less time and with fresher legs. The 6061-T6 aluminum frame and carbon fork are designed around our egravel geometry for a stable, comfortable riding position, even at higher ebike speeds on gnarly roads. With a Bosch Performance Line Speed mid-drive system and 625Wh battery, you’ll fear no route — take on long miles and steep climbs with gusto. Our Class 5™ VRS (vibration reduction system) and ample tire clearance cut the harshness of minimum-maintenance terrain. Rack and Three-Pack mounts let you customize cargo setups for day-ride or bikepacking loads. To top it all off, Shimano’s GRX 600 drivetrain is a proven performer in the gravel realm. See what’s possible with the pinnacle of electric gravel bikes.
