Today, bitlock, a bicycle Bluetooth smart lock, was launched on KickStarter with a funding target of US $120000. Bitlock will completely liberate users from the key, and can control the trivial opening and closing only by the application on the smart phone. Bitlock retails at $140, but KickStarter donors can enjoy a $79 discount. There is no difference in the appearance between bitlock and the bicycle U-lock we usually contact. The Bluetooth in bitlock will automatically detect the corresponding mobile phone application. If the owner is close to the bicycle, bitlock will automatically unlock, and the owner only needs to press one setting in bitlock The car can be unlocked with a small button on. The owner does not even need to take out his mobile phone to do any operation. The process of locking the car is the same as unlocking. Of course, the owner can manually open or close the lock in the application.
