"How do you carry small items?"

A basket isn't my style, and a bag isn't big enough. But I don't need a heavy-duty rack either.

"JACK THE BIKE RACK" is an incredibly smart solution to that "in-between" problem of daily life and riding.

It's a new concept front rack that strikes the perfect balance between the ease of tool-free attachment/detachment and the load-carrying capacity of a rack.

A new rack mechanism that can be installed without tools

A structure that allows "use only when needed"

It's secured at three points: a hook on the handlebars, a strap under the stem, and tension applied at the steerer tube.

While it may take a little getting used to adjusting the length and handling initially, once set up, attachment and detachment are smooth.

Unlike traditional bolt-on racks, its biggest feature is that it's designed to be removed.

"Just right" carrying capacity, neither a bag nor a basket

Flexible "rack-style loading"

The charm of a rack is that you can carry items regardless of their size or shape, as there's no need to fit them into a specific container.

With bungee cords or straps, you can secure boxes, bags, or anything else as is.

Items that won't fit in a bag can be carried, and it doesn't have the fixed appearance of a basket.

This "intermediate freedom" creates a just-right usability for daily use.

Just the right strength and practicality you'll understand when you use it

Designed with "ease of use" prioritized over rigidity

Compared to bolt-on racks, the rigidity is more moderate, but in return, it's overwhelmingly lighter and easier to handle.

It's designed for natural use, where you attach it only when needed and remove it when not in use.

It offers a degree of freedom not found in traditional racks, such as using it across multiple bikes or for different purposes.
