A technically simple and highly securing bike lock device consists of a flipping piece. The flipping piece is supported by a key that is inserted within it and pushed up for locking. The reason why it is a smart device is the fact that it securely withholds the mountain bike onto a vehicle.
There is a highly powerful back lock as well. It sustains the bike onto its vehicle and comes in handy in case the front lock fails. With this bike lock device, it gets extremely convenient to tag along with mountain bikes up the hill with the help of any vehicle.
