Riding a bicycle can be "seemingly" monotonous, at least to the pedestrians next to it. If you want to show people how happy you are on the road, this is the best thing to do. As long as it is installed on the wheel, when YOU ride the LOVE horse around, it will show the words YOU set on your tire, such as "I LOVE YOU", "JUST FOR YOU" and other nine kinds of built-in information. If you have nothing to confess, then choose to show your speed now!
