Since spring has arrived, we have much more power for everyday tasks. We’re doing overhauls in our apartments, decorating the backyard, sometimes even going for a short trip to the Paris. But the most humans start to exercising. They are going to the swimming pool, practicing Yoga, having great time on the mini golf. When you don’t have to much time for any tasks like that, but you still wish to get in shape, you should start to use a bicycle. But not regular one – so design your own bike!
