Cage-less Koala Bottle sticks to the bike using magnets

The standard bicycle water-bottle-and-cage system is pretty tried and trusted. That said, at one time or another, just about every cyclist has dropped their bottle on the road when they didn’t put it back in the cage properly ... or perhaps they’ve even wiped out, because they were distracted by trying to remove or replace the bottle. That’s why Anthony Goldman created the Koala Bottle system, which uses magnets to keep the bottle attached to the bike.

The system consists of a normal-looking water bottle with a metallic ring around its neck, and a polycarbonate bike-mounted cradle with two integrated curved magnets at the top. When the bottle is held close enough to the cradle, the ring is drawn to the magnets, causing the bottle to suck into place against the cradle with a satisfying “click.”

Because the cradle is completely open along the top, users can simply reach straight down to remove or replace the bottle, instead of having to first slide it out of a cage.

As noted in a report on BikeRadar, Goldman isn’t the first person to put magnets to such a use. Vincero also makes a magnetic water bottle system, although it requires the use of a specific bottle, which must be replaced in a specific orientation in order for the magnet to engage. Anthony’s system uses ordinary plastic bike bottles – the rings can even be purchased on their own, and applied to existing Specialized bottles. Additionally, the ring has no one side that has to be lined up with the magnets.

As can be seen in the promotional video below, Goldman invented the system when he was in hospital, being treated for a serious cardiac problem. “I knew that I had to do something with my life, and I got tired of having good ideas and not following through,” he said.

The Koala Bottle system is available via the company website, priced at US$27 for a 21-ounce (621 ml) bottle, and $29 for a 24-ouncer (710 ml). The bottle rings can be purchased for $8 a pair.

Another interesting alternative to sliding a bottle in and out of a cage – besides using a hydration pack – is the the BlueDesert H2Bike. It’s a handlebar-mounted drinking hose that’s attached to a regular cage-mounted bottle.

I am going to guess that it is a little heavier but if you have a problem with getting your bottle in and out of the holder it might be well worth it.


What is that thing in the picture, which holds the bottle? It looks like a cage to me. I can't see why this is much of an improvement. It probably cost more than the normal cage.


yeah i don;t really get it if it is such a problem to get the bottle in a normal cage, why is this easier?

you still have to get it in a very specific spot, so the magnets can catch it why is that easier than hitting the opening of a regular cage?



this would be really good for the behind the seat cages, but in my experience they do not hold bottles on bumpy roads. I would be curious to see how they handle bumpy roads and if hte magnets actually keep the bottles in place through the bouncing. As for downtube type application? Don't really see a benefit over a regular cage. Just sayin..

Looks fine until you try to stick it to the light aluminum or carbon fiber bikes.

It is not a cage it is a a cradle.

The magnets guide the bottle into the cradle giving you tactile feedback over a much large area when trying to put it back.

The cradle is mechanically attached to the frame.
