FAQs
What are the differences between the U8 Series models?
The U8 Series includes four models — U8, U8 Pro, U8 Plus, and U8 Ultra — each designed for different riding needs.
U8: 1000W peak power, up to 120 km range, 20×3" tires — compact and powerful for daily commutes.
U8 Pro: 1000W peak power, extended 168 km range, 20×3" tires — same size with a larger battery for longer rides.
U8 Plus: 1500W peak power, up to 120 km range, 26×4" fat tires — bigger wheels and stronger motor for off-road versatility.
U8 Ultra: 1500W peak power, extended 168 km range, 26×4" fat tires — the top-tier model for maximum power and endurance.
Each model offers the same isinwheel quality and comfort but varies in power, range, and tire size to fit different riding styles.

The IP65 waterproof rating allows you to ride confidently in various weather conditions.
