We’re a genuine, authorised retailer for selected brands, with our own Nuneaton repairs workshop.
Buying iSinwheel online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.

Compact U1 commuter e-bike | Different model from the EB1S APP variant | Manufacturer-stated range up to 28 miles
The isinwheel U1 Mini Folding Electric Bike combines compact convenience, practical functionality and responsive electric assistance. Featuring a 36V 7.8Ah lithium-ion battery, 14” pneumatic tyres, central spring suspension and a space-saving folding frame, the U1 is designed for everyday commuting, short urban journeys and convenient travel, offering an adaptable solution for riders seeking a compact electric bike.
Smooth & Responsive Electric Assistance
The U1 features an electric hub motor designed to provide responsive assistance for everyday commuting and moderate inclines. Adjustable riding modes allow riders to tailor their cycling experience, delivering convenient electric support for navigating urban streets and suitable cycling routes.
Compact & Convenient Folding Design
Built around a durable aluminium alloy frame, the U1 features a practical folding design that makes storage and transportation more convenient. Its compact 14” wheels and space-efficient construction make it particularly suitable for smaller homes, limited storage areas and transportation in a car boot.
Efficient 36V Lithium-Ion Battery
Powered by a 36V 7.8Ah (280.8Wh) lithium-ion battery, the U1 offers a manufacturer-advertised riding range of up to 28 miles under optimal conditions. Its integrated battery system supports everyday commuting and recreational cycling, with a typical charging time of approximately 3–4 hours.
Comfortable Suspension & Reliable Braking
Equipped with central spring suspension and 14” pneumatic tyres, the U1 helps reduce the impact of bumps and uneven surfaces for improved everyday riding comfort. Front and rear mechanical disc brakes provide controlled stopping performance, giving riders greater confidence when navigating urban environments.
Practical Technology & Everyday Versatility
The U1 features an easy-to-read LCD display, providing essential riding information including speed, battery level and assistance settings. Integrated lighting enhances visibility, while its adjustable seating and compact frame make it a convenient choice for local travel, commuting and relaxed leisure rides.
UK Road Use Compliance
Before riding the U1 on UK public roads or cycle paths, confirm that the exact supplied motor rating, assistance cut-off speed and throttle configuration comply with UK EAPC regulations.
