Luminous bicycle
This is a Luminous bicycle around many photoluminescent films by Pure Fix Cycles, a Californian brand called the kilo, and that's what most flighters want to look like, by leaving their bikes outside in the sun for a few hours during the day.
It can make the special material on the frame or the rim shine at night, which is not only eco-friendly, but also greatly improves the safety factor of users when riding at night, which is really good.
