Stout is our take on the modern commuter bicycle, giving you an outstanding riding experience, coupled with the support and comfort you expect from a ride-everywhere commuter. The unpretentious looks hold a versatile and strong nature beneath– a fast-going citybike that feels trustworthy in all situations.

Stout’s 9 gears, wide tyres, high handlebars and full mudguards make it a favourite amongst all types of commuters, as it can take on any riding situation you put it up against. Weighing only 17.2 kg, it’s light to carry up and down the stairs.

Purposeful
Equipped and always prepared

The wide tyres, full mudguards and comfortable riding position make Stout prepared for every occasion. You’ll always feel confident to take on any weather and road condition your commute puts you up against.

Electric assist
Smooth, intuitive and safe

The bike’s torque sensor constantly measures how hard you pedal and calculates the level of assist for the electric motor. The motor provides more assist the harder you pedal, and less assist the lighter you pedal. This puts you always in control of the bike and keeps your ride safe.

Battery and range
70 km on one charge

The average battery assisted range is 70 km, giving you peace of mind on all your rides. And even if you run out of juice, you simply keep on cycling. One hour of charging will give you 33 km of range, and it takes just 2.5 hours for a full charge.

Frequently asked questions
Where is the battery?

The battery is integrated into the down-tube of the frame. The frame and the battery are designed in such a way that every professional bike shop could remove the battery, and if needed, replace it with a new one in under one hour.

How to charge the battery?

The battery is charged with the charger, which comes with the bike. The process is similar to charging your laptop – you have to connect the bike with a standard wall power outlet.

Why do I need the mobile app?

You can use our mobile app to:

  • Navigate and track your rides
  • See your riding history
  • Adjust the motor settings
  • See your battery level
  • Use the app as a display

You can get the free Ampler Bikes app from Play Store (Android) and App Store (iOS). You can also change all the standard functions from the Power Button on your bike.

Which frame size should I get?

You can find your perfect frame size based on your height:
160 - 170 cm = Small frame
170 - 185 cm = Medium frame
185 - 200 cm (and above) = Large frame

The geometry of the bike is made according to the most ergonomic and optimal seating position.
If your height is right in the middle of two frame sizes (e.g. 185 cm) we recommend you taking the smaller frame.
