My light is broken or works poorly

Last updated on 28 Oct, 2025

When it's dark outside the lights are used frequently and the batteries may run out. The bike comes with functioning batteries, but if they run out it's up to you to replace them. Here is how you replace lights or batteries:

1. The rear light runs on 2 AAA batteries and the front light on 3 AAA batteries. The rear one you open by folding out the above transparent plastic component. The front one you unscrew with a Phillips screwdriver from below.

2. You can always stop by the shop and we can quickly replace the lights or batteries if needed. We charge 7 kr for a AAA battery in our store.
