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. Meets UL 2849, and UL 2271 certification
