Since spring has came, we have far more energy for each day activities. We are doing overhauls in our houses, rearranging the backyard, sometimes also going for a longer weekend trip to the mountain. But the most people begin to exercising. They're going to the gym, practicing Yoga, having nice fun on the mini golf. When you do not have to many time for any tasks like that, and you still wish to stay in shape, you could start to use a bicycle. But not regular one - you have to design your own bike!
