In April days are getting warmer and spring may be felt up in the air. Humans are very frequently leave their apartments just to be outdoors. They are doing some exercises like running or pilates on the balcony. Different ones are planning to choose a bicykle as their primary mode of transportation. Do you wish to be one of them but you do not have your own vehicle? Not a big deal, there are plenty of places where you could buy one in reasonable price, like at the internet or local shop. Also, you could design your own bike.
