LifeSpan Ampera Power-Generating Under Desk Bike

A desk bike that charges your phone while you pedal

The Ampera turns your own pedalling into power. At a casual 60 rpm it generates up to 65 watts, enough to charge a laptop or phone through the USB-C port, and there is a 15W wireless charging pad under the seat for your phone or earbuds. Pedal for an hour and you burn around 500 calories while topping up your devices.

It is built to a genuinely high standard: a near-silent belt drive at around 50 dB, a thick high-density seat, one-finger pneumatic height adjustment for users from 5 foot to 6 foot 5, an app-controlled RGB ring light, and a frame made from over 30 percent recycled materials. App-adjustable resistance and a lifetime frame and motor warranty.

Common questions

Does it really charge devices? Yes, up to 65 watts via USB-C plus a 15W wireless pad under the seat, powered entirely by your pedalling.

Is it quiet? Very. The belt drive keeps it to around 50 dB, about the level of a quiet conversation.
