The isinwheel U8 Ultra Electric Bike is the top-tier model in the U8 series, built for riders who want maximum power, long-distance capability, and all-terrain performance. Whether you’re commuting, cruising, or tackling rough trails, this e-bike is designed to handle it all with ease.
Equipped with a 1500W peak motor, the U8 Ultra delivers strong acceleration and can reach speeds of up to 28 MPH (Class 3), making it ideal for both urban roads and off-road adventures.

Built for rugged performance, the bike features 26” x 4” fat tires that provide excellent traction and stability across sand, snow, gravel, and uneven terrain. Paired with a front suspension system, it ensures a smooth and controlled ride even on bumpy paths.
The step-thru aluminum alloy frame makes mounting easy while maintaining durability and strength. A Shimano 7-speed gear system allows seamless gear shifting, and multiple riding modes—pedal, pedal-assist (5 levels), and throttle—give you complete control over your riding style.
Designed with safety and convenience in mind, the U8 Ultra includes an advanced BMS 2.0 battery management system, IP65 water resistance, and a removable battery for easy charging. With a maximum load capacity of 330 lbs, it’s built to support a wide range of riders and riding needs.
