Stellar is an e-bike build to fit your life, not the other way around. Electric motor support and 9 gears take the strain out of commuting, daily errands and weekend tours. Puncture-protected tyres keep you safely on the road in all conditions.
Stellar makes everyday life more convenient by unchaining you from the traffic gridlock. It gives you extra power and the option to carry everything you need during your ride – from pannier bags to groceries and a child seat. 
Simple to use
Stellar is light to lift and simple to use – press the power button, start pedalling and simply ride. When you ride up a hill, the bike automatically gives you extra support so you don’t have to change modes while riding.

Powerful integrated lights

Stellar comes with bright, fully StVZO approved front and rear lights, so you will always stay visible. You also never have to worry about forgetting the lights home or about them getting stolen.

Strong disc brakes

Stellar has Shimano hydraulic disc brakes that are designed for high braking power, reliability and easy maintenance.

Puncture-protected tyres

City streets often have broken bottles and sharp stones that create punctures and flat tyres. To remove that worry, Stellar comes with lightweight Continental puncture-protected tyres.

Mobile app connectivity

You have a window into your bike via Ampler mobile app, where you can customise the motor assist settings, track your rides, navigate with built-in maps, and receive over-the-air updates.
