JACK is a universal-fit front bicycle rack that securely straps to almost any bike, offering a straightforward solution to carrying your things with you while you ride.  A ‘Rack of all Trades’, JACK fits to your bike with a tool-free strap system, requiring no special bicycle frame or fork, no specialist equipment and no bike maintenance skills.


Where does Jack the Bike Rack come from? We’re a bike component and accessories startup founded by a group of bike lovers and adventurers with years of industry experience. Dedicated to simplifying an arena plagued by daunting tools and over-engineered accessories; We’re on a mission to create versatile, thoughtfully produced, easy-to-use accessories that anyone can install and enjoy.

Human solutions for humans who ride bikes!

There aren’t any international standards that apply to JACK, but that hasn’t stopped us testing JACK to destruction: We’ve taken JACK on rough roads and singletrack with extremely heavy loads. We’ve also put JACK through his paces in the lab, with our own tests that we’ve created based on JACKs extreme use-cases.

We spent a full year searching for the right factory, to make sure the we can get JACK to you reliably and at the best quality. And we found a brilliant factory partner, with years of experience building and shipping high quality bike racks.

It’s not easy to create a totally new supply chain, but we decided to do it ourselves, with no agents or middle men, so we understand everything thats going on ‘behind the scenes’.

Long-lasting design

We’ve designed JACK with no mechanical fixings and few failure points. And anything that does suffer from general wear and tear is easily replaceable. Designing JACK in this way (design for disassembly) means that JACK and his parts are also cheaper to produce for you!

Reusability and recyclability

JACK is designed for disassembly, therefore at the end of his life, or after any wear and tear gets too great, it’s easy to make sure any waste can be easily separated into the correct waste stream. We’re smart like that 😉

Why does JACK exist?

JACK is a response to over-engineering and over-integration in the bike industry on the whole, but now it’s starting to creep into the adventure biking and utility bike scene! We want everyone, not just bike geeks, to be able to make the most out of their bike, whether they’re bike packing or commuting. JACK has been created for that very reason.

How much can JACK carry?

JACK has been designed, lab and real world tested to carry a maximum of 5kg. However, at your own risk, and depending on your terrain (smoother road surface = more weight possible) you can load him up with more. BUT your handling will become significantly negatively affected so we don’t recommend anything above 5kg. With regard to size, the sky is the limit. But please, ride and load up safely.

How do I fit JACK to my bike?

Can I fit JACK to carbon bars and stems?

Yes, you can. In fact, it’s better than any clamping (Other structured handlebar gear haulers) or strapping (Handlebar bags) systems you might use instead, due to its rigid, minimal rub design. There are also no bolts to over tighten and crush your bars. There may be a little rubbing between the spacers and the side of the stem faceplate, but this will be dependent on the stem faceplate shape. Also, if your carbon bars have protruding or poorly applied decals, they may get damaged too.

Does JACK pass all the relevant safety tests?

There is no current international or national standard or standard test for a product like JACK. However, we are using the International standard ISO/BS/EU 11423-2016 as a baseline to conduct our own tests that we feel are most relevant. It’s important to make sure JACK is not just smart, but also totally safe (when attached and used as we instruct/advise).

Is JACK compatible with my bike?

JACK is compatible with almost any bike that has either a 31.8mm or 25.4mm handlebar stem clamping area (90% of the old and new bicycles made). Definitely more than any other front bike rack we know of. However, there are also certain spacing requirements. If you’re still not sure, send us a picture of your set up via email (max@bikepackshop.com) to help us advise you.

What happens if JACK breaks? Will it break?

In the extraordinary case this happens, firstly, send us a picture of how you broke it. It will be an achievement! Secondly, we will hold replacements for every part. The price will be fair for them, and they are very easily replaced. If the straps break while you’re in the middle of nowhere, you can use any straps, wire, cloth, whatever to replace them, and still get back to civilization. We’ve designed JACK to be easily retrofittable with whatever you have lying around.

What’s in the box?

JACK (the rack) with removable fabric base. Two 31.8mm handlebar shims. Two 25.4mm handlebar shims. Two taper shims for the 25.4 handlebars shims. Four (different) stem load straps. One adjustable steerer retention strap. Two 1.2m bungee straps with snakehead buckles and carabiners. Instruction manual.

How much does JACK weigh?

With all straps and spacers on JACK, it comes in at 700g.

What Handlebar Sizes does JACK fit?

JACK will fit all the most common handlebar sizes. The measurements below refer to the stem clamping area, as this is where JACK mounts. 31.8mm 25.4mm 22.2mm + 25.4mm that sharply tapers down to 22.2mm JACK doesn’t fit 35mm handlebars as accommodating this size of bar would compromise JACK’s fitment onto 22.2mm handlebars, which is a bar size that are fitted to bikes that we feel have much more to benefit from JACK. We are sorry that our current design doesn’t accommodate 35mm bars, however!

Jack the Rack has been hot in the press!

“Jack the bike rack is ingenious. The nearly universal fit is going to be a gamechanger for people who are basket-curious or battle with their front tire rubbing their handlebar bag and don’t have any mounting points to use a more traditional front rack. It’s clear that the team at WholeGrain Cycles has put a lot of time and energy into the design of Jack, and the final product is functional and competitively priced.” – Bikepacking.com

“Bikepacking bags are great and all but nothing beats a rigid support system when it comes to traveling, touring, and camping by bike. The problem is, not all road or gravel bikes have rack support bosses on their carbon forks. Jack the Bike Rack clamps to your bars and can be fitted to just about any bike without any frame or fork modification.“ – The Radavist
