Since spring has came, we have much more power for each day activities. We are doing renovations in our houses, decorating the backyard, sometimes also going for a longer weekend trip to the Paris. But the most people begin to exercising. They're going to the swimming pool, practicing Yoga, having nice fun on the mini golf. When you don't have to many time for any tasks like that, and you still want to get in shape, you should start to use a bicycle. But not regular one - so design your own bike!
