Tributary Apex Eagle SUS makes backcountry odysseys more accessible than ever. Our egravel geometry puts you in a stable, comfortable riding position on the 6061-T6 aluminum frame. A 120mm suspension fork and our Class 5™ VRS (vibration reduction system) devour rocks, ruts, and washboard roads. Bosch’s Performance Line Speed mid-drive system and 625Wh battery help you expand your range of operations — explore every spur, see what’s at the top of that silly-steep climb, and venture miles farther than usual in less time. Rack and Three-Pack mounts let you load up without feeling the weight penalty (be the hero who brings the cast-iron to the overnighter). SRAM’s Apex Eagle drivetrain grants you a wide-range 12-speed cassette and the joy of perfect, effortless shifts every time. Tributary Apex Eagle will show you what adventure ebikes are capable of, so you’d better start plotting.
