Versatile Riding Modes: Power When You Need It
The isinwheel U3 gives you multiple ways to ride with its flexible power system. The 250W brushless motor integrates directly into the wheel, delivering smooth acceleration and reliable power.
You can choose between full electric mode using just the throttle, three levels of pedal assist that add power as you pedal, or regular bike mode when you want to exercise or your battery runs low.
The throttle lets you adjust speeds between 6 mph, 9 mph, 15.5 mph, and 18.6 mph (10 kph, 15 kph, 25 kph, and 30 kph), giving you control over your ride. The motor performs well on hills and against headwinds, helping you maintain speed without getting tired.




Go Further, Charge Faster

Suspension Where It Matters: Comfort on Any Road
Riding the isinwheel U3 feels good even on rough roads thanks to its thoughtful suspension system. The front fork absorbs the initial impact of bumps and potholes, while the shock-absorbing seat further reduces vibrations that reach your body.
The 16” × 1.75” pneumatic tyres provide a good grip on various surfaces while maintaining efficiency. The adjustable handlebar height lets you find the perfect riding position for your body, reducing strain on your back, shoulders, and wrists during longer rides.
The breathable ergonomic sport cushion seat adds comfort for your sit bones, making longer rides much more enjoyable. Together, these features create a smoother, more comfortable ride than you'd expect from a compact folding bike. Isinwheel Ultra Rider, at 51.4 lbs (23.3 kg), is lighter than many e-bikes, making it possible to carry short distances when folded.




Safety First, Confidence Always
The Zoom hydraulic disc brakes with 160 mm rotors on both front and rear wheels provide powerful, consistent stopping power. The bright 111-lumen LED headlight illuminates your path in low light, while the taillight makes you visible to others from behind.
The LCD display is clear and easy to read even in bright sunlight, showing your current speed, battery level, and assist mode without distraction. Meanwhile, the adjustable seat height accommodates riders from 5'1” to 6'1” (155-180 cm), ensuring proper leg extension.
