We’ve created a video guide for you to see how the bike will be assembled out of the box, watch it here on YouTube:

We ship the bike together with an assembly guide and the tools you need for setting the bike up. If you want to read about the setup beforehand, and generally learn more about your bike, have a look at the manual here.

The power button is the control hub for your Ampler e-bike. With the power button, you can:

• Turn the bike ON and OFF — A quick press on the button turns the bike on/off.   
• Turn the lights ON and OFF — When the bike is on, holding the button down for 1-2 seconds turns the lights on/off
  
• Switch between the different assist modes — When the bike is on, holding the button down for 3-4 seconds will switch the assist modes.
  
• See how much battery you have left
  
  

You can turn the bike ON and OFF from the power button — a quick press on the button turns the bike on/off. 

The right tyre pressure guarantees low rolling resistance and also better response between the torque sensor and the motor, and has a significant impact on preventing punctures.

Depending on your body weight and desire for comfort, you can vary somewhat, but bear in mind:

• Underinflated tyres can cause the motor assist to cut out or the ride to feel heavier – and significantly increase the risk of punctures due to so-called “snakebites”.
• The maximum tyre pressure is defined by the tyre manufacturer. In general, the information on the sidewall of the tyre is the maximum value and should not be exceeded.
• The graph shows in the green area a suggestion between comfort (lower tyre pressure) and speed (higher tyre pressure).
• You should not stay in the lower red area. Beyond the green area the driving feeling becomes considerably “stiffer”.

The graph below shows a suggestion between comfort and speed. You should check the tyre pressure before every ride or at least once a week. We recommend buying a floor pump with a pressure gauge which clearly shows the tyre pressure. The graph of course only applies to the tyres we equip our bikes with ex works.

Charging your e-bike battery is very easy — simply use the charger that comes with your Ampler bike. Your Ampler has a magnetic plug for connection to the charger. You only need to connect the cable to a standard socket (110–240 V AC).

You can turn the lights on either by pressing the power button on the bike for 1 second or by using the Ampler mobile app.

The frame number starts with ‘AMP’ and is engraved on the right side of the bike on the chainstay, next to the rear dropout. You can also find it on your bike passport.

A Software restart clears up your bikes memory and starts it fresh.

To reset your bike:

1. Hold down the power button for at least 10 seconds (20 seconds if you have a model before 2017) until the LED light turns off along with the bike
2. Turn on the bike on again from the power button or let a charge a while, if the battery has run out
3. Check the connection via your app and see if everything works as it should
