Pedaling through sand and mud is usually a sufferfest. Not so on XTerrain’s new ultra-fat fat bike.
Dubbed the Xterrain500, this supersized, 70-pound whip uses a 10-inch ATV tire up front for maximum float (about double the size of most fat-bike tires), and a 500-watt electric motor to move all that rubber. The bike also comes with a standard 4.5-inch tire. The custom RockShock fork is adjustable to fit both sizes.
The bike has a top speed of 20 miles per hour and can travel about 20 miles per charge.
