Awesome! You found bike polo and our little forum. Here are some useful links and resources which should make it easier for you, to start with your new passion!
First, you’ll need a place to play. Check out this list of all european clubs. This is probably out of date already - so if you can’t find a club near you, it’s worth it to keep asking around!
Next, you’ll need some equipment. Usually, we polo people are nice and let you use our equipment for the first few times. But eventually, you’ll want your own gear. Check out the Marketplace to find second hand gear and this list of Polo Brands for new gear.
