Description
The complete courier setup
Bigger days.
Better supported.
Deliveries, longer rides, and a backpack that has a job to do. The Pro pairs Backbone 8.3 with the wider V Platform and Black-BONE cable-and-winch system for heavier loads.
Your backpack stays on you. The support beneath it lets the bicycle carry the load.

Included with Pro
A complete setup. A personal touch.
V Platform
A broader support surface for messenger bags and large backpacks. Included in place of the rectangular platform.
Cable-and-winch support
The Black-BONE system adds support for heavier loads and increases the Backbone’s carrying capacity.
Personalized setup review
Complimentary help getting your bike, backpack, platform position, and cable setup working together.
Room for your bag. Less bulk to pack.
A wider platform.
An easy getaway.
The padded V top quick-releases from its shaft. Separate the two pieces to make the platform easier to stow between rides.
Release the top, lift it off the shaft, and stow the pieces together. Reattach securely before riding.

Black-BONE included
Extra support for the heavier days.
The cable-and-winch system is what separates Pro from the $95 Standard V package. It reinforces the support for heavier loads while you keep the wider platform underneath your bag.
Pro brings the components together for $120, with a personalized setup review included. Already have a Backbone? Add the Black-BONE accessory for $25.
Your Pro setup review
Get it dialed in with us.
After your Pro arrives, contact Support with your order number and photos of your bike and backpack setup. We’ll help you review platform position and the cable-and-winch setup, and point you to the relevant installation guidance.
Included with your Pro purchase at no extra charge. Follow the installation guide and all safety checks before riding; a photo review does not replace those checks.
The reflective Backbone decal
Catches the light.
A subtle detail by day. A bright accent when light hits it after dark. The Backbone lettering is reflective.
Reflective, not self-illuminating. Keep using appropriate bicycle lights and reflectors.

A real problem.
Thousands of miles to solve it.
BikeBackbone began during founder Adam Keen’s long-distance bicycle journey from the Chicago area toward Panama. A heavy hiking backpack created the problem; prototypes built along the route became the product.
