Versatile. Urban. Unconditional.
Ampler Stellar is a unisex commuter e-bike. Stellar offers you the comfort and flexibility of a lightweight city bike, and the smooth and powerful motor support of a smart electric bike. Regardless of whether you have to quickly cycle from A to B, overcome hills on your route, or carry heavy bags on your bike, Stellar is your faithful companion at all times.
Trustworthy electric commuter bike
Stellar e-bike is designed for use in all conditions. The step-through frame, wide tyres, 10 gears, mudguards and comfortable saddle make Ampler Stellar a perfect all-round urban bike for city commuters. It is built to last for ages and designed to handle both fast commutes in city traffic as well as slow weekend cruises on unpaved roads. Weighing only 17.2 kg, Stellar is also easy to lift up and carry if needed.
Equipped with everything you need for city commuting
Every part on the Stellar e-bike is handpicked for quality. The rear carrier creates enough space to carry everything from grocery bags to laptops and child seats. The bright integrated light set illuminates your way in the dark, the hydraulic disc brakes keep you safe in city traffic and the puncture-protected tyres from Continental let you cycle worry-free even on the roughest roads. The resulting bike is a versatile men’s and ladies’ electric bike that you can always rely on.
