The Heavy Duty AX4 Rear Bike Rack – Black features aircraft-grade aluminium construction, a 4th vertical spur to keep bags clear of tyres, and a corrosion-resistant anodised finish.

The Heavy Duty AX4 Rear Bike Rack with 4 Vertical Spurs – Black is built for cyclists who demand maximum strength, stability, and reliability for heavy-duty touring and everyday hauling. Crafted from aircraft-quality aluminium, this rack is engineered to withstand the toughest riding conditions while keeping weight to a minimum.
Its standout feature is the 4th vertical spur, a smart design element that keeps larger pannier bags away from the rear tyre. This prevents rubbing or interference, ensuring a smoother, safer ride even when carrying bulky loads.
The tough anodised finish offers excellent corrosion resistance, protecting the rack from rust and wear caused by wet or muddy conditions. This makes it a long-lasting investment for riders who cycle year-round in all weather.
With a maximum load capacity of 27 kg, the AX4 is ideal for carrying camping gear, groceries, work equipment, or touring essentials. Despite its strength, the rack remains lightweight at just 0.854 kg, so it won’t slow you down on climbs or long rides.
The AX4 is compatible with 26″ mountain bikes and 700c trekking bikes that do not have disc brakes, making it a versatile choice for a wide range of setups. Installation is quick and straightforward, so you can get on the road without fuss.
At Blue Door Bicycles, we believe in providing cycling solutions that combine robust engineering, practical features, and long-term durability. The Heavy Duty AX4 Rear Bike Rack is a perfect example — a rack that’s as dependable on a cross-country tour as it is on a daily commute.
Upgrade your carrying capacity with the Heavy Duty AX4 Rear Bike Rack with 4 Vertical Spurs – Black and enjoy the perfect blend of strength, stability, and lightweight performance — every ride, every time, with Blue Door Bicycles.

Bikes Delivery Information
Bike & Ride – The Premier Option for You
Blue Door Bicycle is proud to be one of the few online bike retailers in the UK offering a delivery service that guarantees your bike arrives fully assembled and ready to ride. Our premier delivery option, ‘Bike & Ride,’ is available for just £70 per bike and ensures that your biking experience starts effortlessly and smoothly.
With ‘Bike & Ride,’ your new bike will arrive in a specially designed bike box with minimal packaging, ensuring protection during transit while reducing environmental impact. Included are all the necessary tools, so you can start riding within minutes of delivery. Our commitment to sustainability means we avoid using foam, bubble wrap, and zip-ties, opting instead for eco-friendly packaging. We encourage you to recycle any materials where possible, contributing to a greener planet and giving you the added satisfaction of making an environmentally responsible choice.
Bike & Ride for Standard Bikes
For standard bikes, our ‘Bike & Ride’ service ensures that each bike undergoes meticulous assembly and rigorous quality checks by our expert bike builders. This attention to detail guarantees that your bike meets the highest standards of safety and performance. To facilitate this thorough process, bicycles are not eligible for next-day delivery, ensuring each bike is perfectly prepared for you.
Bike & Ride for E-Bikes
Due to the additional weight and unique handling needs of electric bikes, we cannot ship them fully assembled. Instead, our expert mechanics will assemble, configure, and thoroughly inspect your electric bike before repacking it in its original box. This process requires the removal of the front wheel, handlebars, pedals, and seat-post, which you will need to reinstall upon delivery. We provide detailed instructions and all necessary tools to help you complete the assembly quickly and effortlessly.
Experience the unmatched convenience and quality of ‘Bike & Ride’ by purchasing your bike from our online shop. With Blue Door Bicycle, you’re choosing a service that prioritises your riding experience, environmental responsibility, and exceptional quality from the moment you receive your bike.
