ECOTRIC Bison 1000W Fat Tire Ebike — Dual Suspension, 37-Mile Range
$999.00

Conquer Sand, Mud, Snow, and Everything Between

Wild, strong, and tough — the ECOTRIC Bison earns its name. This vetted fat-tire ebike pairs a 1000W brushless motor with dual suspension (Mozo hydraulic front fork plus mid-mounted shock) to absorb whatever the trail throws at you. The 48V 17.6AH lithium battery delivers up to 37 miles of range on a single charge, while 26 x 4.8-inch tires grip sand, mud, snow, and tarmac alike. Backed by Shimano 7-speed gearing and hydraulic disc brakes on both wheels, it's a serious investment in off-road capability — the kind of craftsmanship we'd park in our own garage.
