This ring frame lock offers a convenient and permanent security solution that stays attached to the bicycle at all times. Finished in a classic black, it mounts directly to the rear stays of the bike frame. When engaged, the steel bolt passes through the spokes of the rear wheel, effectively immobilizing the bicycle and preventing it from being ridden away.

The integrated design means there is no need to carry a heavy chain or u-lock for quick stops. It is particularly popular for urban commuting and short errands where a fast and simple locking mechanism is required. The mounting bracket is designed for a secure fit, ensuring the lock does not interfere with the normal operation of the bicycle while riding.

Constructed with durability in mind, the housing is built to resist the elements and daily wear. This type of lock serves as an excellent primary security measure in low-risk areas or as a secondary lock to supplement a cable or u-lock in busier locations. Its unobtrusive profile and ease of use make it a practical addition to any city bike.
