The problem

Your backpack should ride with you.

A backpack gives you freedom off the bicycle. On a long ride, that same weight presses into your shoulders, back, and saddle position.

The transfer

Let the bicycle carry the weight.

The Backbone rises behind the saddle and supports the bottom of your backpack while you continue wearing it. The load moves off your body and onto the bicycle.

The freedom

Ride supported. Walk away ready.

No panniers to unpack and no bulky side load. When the ride ends, your backpack is already with you—exactly where it belongs.

The bicycle accessory that supports your backpack’s weight while you ride.

Your backpack should ride with you—not weigh you down.

The Backbone supports your backpack behind the rider, taking pressure off your shoulders while keeping your setup compact.

A better way to ride with a backpack.

Supports the Weight

Let the bicycle carry the load instead of your shoulders.

Installs Without Tools

Quick-release hardware makes setup simple and fast.

Compact Behind You

Keep luggage centered rather than extending from both sides.

The Backbone gives a backpack the support it always needed.
