The fact that the reacha can be dismantled is a central feature of our device. That was the main reason to manufacture the reacha in this way and is a main reason for the purchase for many of our customers.The two side parts of the main frame with the wheel mounts are firmly bolted and can only be opened with a special tool.By routing a long cable lock through these frame parts and the wheels, which then connects to the bike or a tree/post, you can protect the reacha from casual thieves. Unfortunately, you will never be able to protect yourself from professionals who approach with bolt cutters, delivery vans or other heavy equipment.
