A Purpose-Built Way to Carry Heavy Security Chains on Bikes and Motorcycles

Purpose-built transport for serious security – on two wheels, motorised or human-powered

Pragmasis has introduced a new Chain Carry Case, designed specifically to make transporting heavy-duty security practical, tidy, and affordable across motorcycles and bicycles.

Developed in response to customer demand, the Pragmasis Chain Carry Case provides a dedicated solution for carrying Pragmasis chains and other security products on a motorcycle pillion seat as it acts just like a tailpack.

The Chain Carry Case also offers excellent versatility for bicycle use. Whether mounted to a front rack on a cargo bike or fixed securely to a rear cargo rack, the case is engineered to cope with the weight and awkward shape of serious security hardware, keeping your security neatly stored and accessible.

Designed for real-world use

Unlike general-purpose panniers or top bags, the Pragmasis Chain Carry Case is compact enough to carry heavy-duty security without being baggy when fitted. Heavy loads such as security chains are easily transported, thanks to double-stitched seams and strong mounting straps.

The bag can be fitted to a wide range of platforms, helping to prevent movement under braking or cornering—an important consideration when carrying high-mass items.

A practical option for cargo bikes

On bicycles, the bag is equally at home on front racks, cargo racks, or rear carriers. It is particularly well suited to compact cargo and utility bikes where secure load control is essential.

The Chain Carry Case also presents a compelling alternative for owners of Tern bikes. It can be mounted to Tern front racks or fitted to rear cargo racks, and the integrated straps make it possible to attach the bag directly to the rear frame system commonly known as the Clubhouse.

Crucially, the Pragmasis bag is smaller, lighter, and significantly more affordable than Tern’s WeatherTop Bag, making it an attractive option for riders who want a robust, no-nonsense carrying solution—particularly when the primary job is transporting security equipment rather than bulky cargo.

• Suitable for motorcycles (pillion seat mounting)
• Easily mounts to bicycle front racks, rear cargo racks, and cargo frames
• Compact form factor with high load stability
• Cost-effective alternative to larger, premium bicycle cargo bags
• Ideal for utility, cargo, and urban cycling use
• Supplied with a shoulder strap for additional portability
• Built for security, priced for everyday use

By focusing on function rather than excess volume, Pragmasis has delivered a carrying solution that complements its security range while remaining accessible in price. The Chain Carry Case is a practical addition for riders who rely on serious physical security and want a transport option that matches the robustness of the products inside.

The Pragmasis Chain Carry Case offers a simple proposition: secure transport for serious security—without unnecessary bulk or cost.
