pumperlock / Combined pump and lock


The most common accessories to the bike are the lock, light, and the inflating pump. Most locks are heavy or hard to carry around. This design not only makes the usage more easier, but also serves as a inflating pump to save the biker the trouble of carrying an additional one.When the bike is on the move, the lock will be fixed on the frame, without the need to take it off.When locking the car, all you need to do is turn the lock bar 90 degrees, and place it horizontally between the wheel and the frame.The lock bar can be used as an inflating pump once taken apart.
