EKX X21 | Off-Road Electric Bike

The EKX X21 Off-Road Electric Bike is a full-suspension fat-tire e-bike built for riders who want to leave the pavement behind without leaving comfort behind. A twin 1000W (2000W peak) 48V brushless rear-hub motor system delivers confident power up steep climbs and across loose terrain, while grippy 20" x 4.0" Kenda fat tires and front-and-rear suspension keep you planted through ruts, gravel, and trail. With a range of up to 90 km (56 miles) on a single motor — and up to 150 km (93 miles) in pedal-assist — the X21 is equally at home on a daily commute or a weekend backcountry adventure.

Five levels of pedal assist and a bright, easy-read color LCD display let you dial in exactly how much help you want, while hydraulic disc brakes and a dual leather seat make long rides safe and comfortable. A 180 kg (396 lb) weight capacity and aluminum-alloy frame mean it's ready for riders of nearly any size.
