When spring has came, we have far more power for everyday tasks. We're doing renovations in our apartments, decorating the backyard, sometimes even going for a short trip to the Paris. But the most people start to exercising. They are going to the gym, practicing Yoga, having nice fun on the mini golf. If you do not have to much time for any stuff like that, but you still like to stay in shape, you could start to use a bicycle. But not regular one - so design your own bike!
