Dual purse pet cord / Pet care items

Bike ride with the lovely pet at the outdoors is a popular activity for the modern people in their leisure time.
So it is not rare seeing rider grips the pet cord with one hand and holds the bike handle with the other one,
which leads the drivers to the danger caused by any accident. The design concept is to set the cord to the seatpost of the bike, it is unnecessary the manual control of the rider, the length of the cord can adjust by itself,at the same time, just like the. way that we use a tape measure,there is a warning light, to remind the passers at night or other moments with poor visibility.
