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 75 miles range, 20×3" tires — compact and powerful for daily commutes.
U8 Pro: 1000W peak power, extended 105 miles range, 20×3" tires — same size with a larger battery for longer rides.
U8 Plus: 1500W peak power, up to 75 miles range, 26×4" fat tires — bigger wheels and stronger motor for off-road versatility.
U8 Ultra: 1500W peak power, extended 105 miles 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.
Is the U8 Series a Class 3 eBike?
Yes, all U8 Series models are Class 3 eBikes, capable of reaching up to 28 mph with pedal assist. You can also use the throttle for effortless riding when you need a break from pedaling.
What makes the U8 different from other commuting e-bikes?
The isinwheel U8 combines city comfort with off-road capability. With wider 20”×3” tires, it delivers extra stability and grip on all kinds of roads. The 1000W motor provides strong acceleration and supports speeds up to 28 MPH, while the Step-Thru frame makes it easy to hop on and off — especially for riders of different heights or for women.
Can I ride the U8 Series off-road?
Yes! Especially the U8 Plus and U8 Ultra, which feature 26×4" fat tires and a 1500W motor — perfect for trails, sand, or snow. The smaller 20×3" models (U8 & U8 Pro) perform best on city streets and light gravel paths.
Does the U8 Series support pedal assist?
Yes. All models feature 5 levels of pedal assist and a twist throttle, so you can choose between full-electric, pedal assist, or manual riding depending on your preference
Is the battery removable?
Yes, the lithium battery is fully removable, so you can charge it on or off the bike for convenience and security.
Does the U8 Series electric bike have a USB port for charging phones?
Yes, the U8 Series E-bike has a USB charging port on the battery. You can charge your phone at any time when you need.
How to get spare parts or after-sales service?

What is the suitable rider height and weight limit?
- U8 & U8 Pro: Best suited for riders between 5'4"–6'2". The bike weighs about 67 lbs and supports a maximum load of 330 lbs.
U8 Plus & U8 Ultra: Designed for taller riders between 5'9"–6'6". The bike weighs about 85 lbs and also supports up to 330 lbs.
Each model comes with an adjustable seat height, allowing riders to find their most comfortable position for commuting or long-distance rides.
Can I ride in the rain or on wet roads?
Yes, light rain is fine. Avoid deep puddles and ensure battery and connectors remain dry to prevent damage.
