Description
iSinwheel U3
The iSinwheel U3 is built for riders who want convenience, comfort, and power in a compact folding design. Featuring a 500W brushless motor, the U3 delivers smooth acceleration and a top speed of up to 18.6 mph, making it ideal for daily commutes and city travel.
Compact & Rapid Charging
Its 36V 7.8Ah lithium battery provides a real-world range of 21–35 miles, but the standout feature is the efficiency—with fast charging in just 2–3 hours, you can get back on the road quicker than almost any other E-bike in its class.
Enhanced Ride Comfort
Designed to soften the journey, the U3 features front suspension and a shock-absorbing saddle to handle bumps and vibrations. The 16×1.75" pneumatic tires offer reliable grip and smooth rolling, whether you’re navigating bike lanes, park paths, or neighbourhood roads.
Go-Anywhere Portability
The foldable frame and integrated carrying handle make the U3 extremely portable. It fits easily into car trunks, office spaces, and public transport. With an adjustable handlebar height, you can find your perfect riding position and switch between three modes: pure electric, pedal assist, or manual pedalling.
Safety & Control
Safety comes built-in with front and rear disc brakes for steady stopping power. The U3 is also equipped with front and rear LED lighting for total visibility, while the easy-to-read LCD display keeps your speed, battery level, and mode right at your fingertips.
