iSinwheel U3 Foldable Electric Bike

Description

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, city travel, and weekend adventures. Its 36V 7.8Ah lithium battery provides a real-world range of 21–35 miles, with fast charging in just 2–3 hours, so you can get back on the road quickly.

Designed for comfort, the U3 features front suspension and a shock-absorbing saddle, helping to soften bumps and vibrations on uneven terrain. The 16×1.75" pneumatic tires offer reliable grip and smooth rolling, whether you’re riding bike lanes, park paths, or neighborhood roads.

The foldable frame and integrated carrying handle make the U3 extremely portable. It fits easily into car trunks, closets, office spaces, and public transport — perfect for flexible commuters or compact living spaces. Adjust the handlebar height for a personalised riding position, and switch between three riding modes: pure electric, pedal assist, or manual pedaling.

Safety and control come built-in. The U3 uses front and rear disc brakes for steady stopping power, along with front and rear LED lighting for visibility day or night. An easy-to-read LCD display keeps speed, battery level, and mode at your fingertips.

Whether you're riding to work, running errands, or exploring new paths, the U3 delivers a smooth, confident, and convenient riding experience — all in a lightweight, go-anywhere design.
