Magical Crank Arms / Lock

Magical Crank Arms
Magical Crank Arms

The bike has a special design. Its crank arms, stand and lock are united. When parking it, you just kick one pole of the two pedals with one of your feet until the two crank arms are both pointing downward, then stamp the two pedals down, making the bike stand on the ground steadily, and at last lock it with a red key just as the picture shows. So you see such a kind of bike can be produced with fewer materials. By the way, what matters is that there is less chance to be stolen.
