Since spring has arrived, we have a lot more energy for each day tasks. We’re doing renovations in our apartments, rearranging the backyard, sometimes even going for a longer weekend trip to the Paris. But the most humans begin to exercising. They are going to the gym, practicing Yoga, having nice fun on the mini golf. When you do not have to many time for any stuff like that, but you still want to stay in shape, you need to begin to use a bicycle. But not regular one – so design your own bike!
