Since spring has came, we have far more power for each day activities. We are doing overhauls in our houses, decorating the garden, sometimes even going for a longer weekend trip to the mountain. But the most people begin to exercising. They are going to the gym, practicing Pilates, having great time on the tennis court. When you don’t have to much time for any stuff like that, but you still like to get in shape, you should start to use a bicycle. But not regular one – you have to design your own bike!
