Ampere Alter — The Award-Winning Folding eBike That Goes Further

If you’re seeking freedom, convenience, and style, the Ampere Alter has it all. This low-step folding eBike is built for riders who are always on the go, with a fast and effortless folding mechanism that makes everyday travel simple — ideal for city journeys, weekend outings, or storing neatly in your car boot.

Power Meets Performance

Powered by a 50Nm motor and offering up to 60 miles of range, the Alter takes the strain out of hills, headwinds, and longer rides. The quick-release battery recharges swiftly, ensuring you're ready to roll whenever you need it.

Premium Components, Outstanding Comfort

Enjoy a smooth, confident ride thanks to Shimano gears, Zoom suspension forks, a clear LCD display, and sleek magnesium alloy wheels. Comfort, practicality, and modern styling come together to create an exceptional folding e-bike experience.

Why Choose Magnesium Alloy Wheels?

Magnesium alloy wheels provide a number of benefits for folding e-bikes. They are around 30% lighter than aluminium, improving acceleration, handling, and overall battery efficiency. Their excellent strength-to-weight ratio ensures durability for urban and light off-road riding. Advanced coatings offer strong corrosion resistance for reliable all-weather performance. The one-piece cast construction removes the need for spokes, reducing maintenance and maintaining perfect alignment, all while delivering a clean, modern aesthetic. Additionally, magnesium naturally absorbs vibrations, giving you a smoother and more comfortable ride across uneven terrain.

Optional Throttle Available

Want to make rides even more of a breeze? This bike can come with an optional throttle - just add the throttle to your cart here.

Please Note – under current UK law, Ampere bikes fitted with the throttle add-on option are illegal to use on public land. These are only to be used on private land with the landowner's permission.
