The AtranVeloSystem is a patented, minimalistic system for the secure attachment of accessories to your bike. It includes a wide range of high-quality bags, baskets, and boxes for different occasions. All accessories are modular and compatible with both front and rear carriers and a latch allows you to intuitively change carriers and accessories with ease.

To attach any bag or basket, simply slide the hook into the small bridge on the carrier.

Push it down til you hear a click.

To remove, simply pull the latch upwards and lift it off.

Functional, Secure, Elegant, and Simple.

Many of our AVS accessories come with a lock and a key.


AVS+ is a reinforced and improved version of the AVS system that seamlessly integrates with all existing AVS accessories. A range of child seats are already on the market, and heavy duty accessories will soon be available, supporting up to 35 kg. This provides flexibility for heavier loads, touring, commuting, or running errands. The robust AVS+ adaptor has a reinforced hook with aluminium for maximum strength and security to the system.

To attach the child seat, slide the hook into the front AVS bridge on the carrier.

When the green color is shown, the accessory cannot be pushed down on the AVS adapter.

Pull out the small security lever to open up the latch. The security latch is now showing a red color.

Pull up the handle and push down until you hear a click (or feel a firm resistance). Then release the handle. Now the child seat is firmly fixed to the carrier, and the security lever shows a green color on the latch.

Lock the child seat with the key to reduce the risk of theft.

The child seat is now securely attached to the carrier and can’t be removed.

Unlock the AVS adapter with the key.

Pull out the security latch.

Then simply pull the handle upwards and slide off the hook from the front AVS bridge.

Now the child seat is loose and can be removed.

The unique feature of TIPLE-X is that you can hang two side panniers/ baskets, plus a stylish accessorie on top at the same time. The luggage will stay firm while riding due to its unique construction. TRIPLE-X takes full advantage of our modular accessories and allows you to easily attach, match, mix, and switch bike accessories more freely.

To attach the TRIPLE-X adaptor, slide the hook into the AVS bridge on the carrier.

Push down until you hear a click. Now the TRIPLE-X adaptor is firmly fixed to the carrier.

Lock the TRIPLE-X adaptor to reduce the risk of theft.

Now the TRIPLE-X adaptor is securely attached to the carrier and can’t be removed.

Side bags and side baskets are easily mounted on the TRIPLE-X by allowing the back rail of the side basket/side bag in its outermost (in the direction of travel) rectangular opening to meet the TRIPLE-X hooks at an approximately 45-degree angle.

When the top end of the TRIPLE-X hook meets the opening on the back rail, you simply slide the side bag/side basket down and towards the side of the carrier.

If desired, the side bag and/or the side basket can also be attached at the bottom to the bike by using the supplied velcro straps.

Add a top bag or a stylish basket to your bike. To put on the top accessory, redo steps one and two.

You are now ready for the ride!

TRIPLE-X is available as an adaptor that is easy to attach and detach from an AVS-carrier, as a stand-alone carrier, and as a unit designed to be installed directly onto your carrier.
