I seriously underestimated those electric bikes! They're quite powerful and you can increase the power once you get the hang of it. And the track is challenging too! If you love motor bikes or just want to give it a try, you should definitely check this out. Perfect activity to do with a group of friends. Also, as it is situated underground, you can try this all year round!
This is truly a pleasant experience! It doesn't matter if you're a tourist who's looking for a more interesting city tour or a local who hasn't seen a new side of his/her hometown. Myself I found it really interesting and this is a perfect way to spend Halloween before continuing the festivities in the center!
