$5,499.00

Is S6DA C GRX 820 the best bikepacking ebike? We think so. Its Bosch Performance Line Speed drive system and 625Wh battery give you the freedom to take the scenic route more often and cover more ground between sunup and sundown. And the carbon frame with our Class 5 VRS™ design soaks up road vibrations to keep you comfortable during those long days in the saddle. Carry anything from your camping gear to your #CoffeeOutside kit with Tributary’s frame and fork cargo mounts. Shift and brake smoothly with Shimano’s GRX 820 components, designed for rugged gravel road use. If you’re on the hunt for a bikepacking ebike — or just curious about the possibilities — S6DA should be on your packing list.
