OKAI Ranger EB50 Electric Fat Tires Mountain Bike - Where Power Meets Endurance

OKAI Ranger Fat Tire Electric Mountain Bike | EB50

Go where pavement ends and the trail begins. The OKAI Ranger EB50 pairs a 750W BAFANG rear hub motor (1000W peak, 85Nm torque) with 26x4 inch fat tires and RST hydraulic suspension to handle dirt, gravel, sand, and snow with the same confidence it cruises city streets. A 705.6Wh Samsung-cell battery pushes range to 45 miles, and speeds top out at 28 mph — enough power to flatten hills and extend your riding radius well beyond the neighborhood.

The full-color integrated LCD touchscreen puts speed, battery, range, and assist level at your fingertips without fumbling with a phone mount. NFC key technology locks and unlocks the bike with a tap, while customizable ambience lighting turns heads after dark. The 6061 aerospace-grade aluminum frame keeps weight manageable without compromising the 330 lbs payload capacity, and the swappable battery design means you can charge off the bike or carry a spare for all-day adventures.
