Product Information

Full details

The Sharp Electric Folding Bike is an ideal solution for urban commuters and city dwellers looking for a reliable, space-saving mode of transport. Its key benefits include a foldable frame for easy storage and a 250W motor that flattens hills and reduces commute fatigue. However, users should note that its 20-inch wheels are optimized for paved city streets rather than rugged off-road terrain, and the overall weight may be a consideration for those who need to carry it up multiple flights of stairs.

FAQs

How long does it take to charge the battery?

Typically, the 10Ah battery takes between 4 to 6 hours to reach a full charge from a standard wall outlet.

Can I ride this bike in the rain?

The bike is designed to be water-resistant for light rain, but it should not be submerged in deep puddles or used in heavy storms to protect the electronics.

How much does the bike weigh?

While the frame is durable, please refer to the technical specifications sheet for the exact weight as it includes the battery and motor components.

Do I need to pedal to make the bike move?

Yes, this model features pedal assistance, meaning the motor activates when you pedal to provide support.

Can I replace the tyres with off-road variants?

The frame is designed for 20-inch city tyres; while other tyres of the same size may fit, off-road tread may increase rolling resistance and reduce the range.

Is the height of the seat and handlebars adjustable?

Yes, both the seat post and handlebars feature quick-release mechanisms to accommodate different rider heights.

Troubleshooting

Motor assistance feels weak

Check the battery connection to the frame and ensure the battery is charged to at least 50% capacity.

Display does not turn on

Confirm the battery is correctly locked into the frame and the power button on the battery unit itself is active.

Brakes feel spongy or weak

Adjust the mechanical disc brake cable tension using the barrel adjuster located at the brake lever or at the caliper.

Pros and Cons

Pros

Foldable frame fits easily in small storage spaces
Removable battery design simplifies charging logistics
Five levels of pedal assistance offer high customization
Shimano 6-speed gears allow for versatile riding
Built-in lights improve safety during low-light commutes

Cons

20-inch tyres have limitations on rough or unpaved terrain
Heavy frame design can be cumbersome to carry
Mechanical disc brakes require periodic manual adjustment

Setup, Compatibility & Care

Before your first ride, ensure all quick-release levers—especially those for the frame hinge and handlebars—are fully locked and tensioned. The battery should be fully charged before the initial use for the best longevity. To maintain the bike, perform monthly checks on brake pad wear and cable tension, as mechanical disc brakes can loosen over time. Keep the chain lubricated and the tyre pressure between the recommended PSI levels to maximize the 60 km range. When folding, ensure the pedals are in a vertical position to prevent interference with the frame hinges.
