We didn’t send anyone to this year’s Sea Otter, but writers from our sister site Mtnbikeriders.com went and covered a lot of goodies in the mountain-biking world. One of the items our pal Art spotted was Koala Bottle — a magnetic bottle/cage system for bicycles:
Here’s a bit straight from the manufacturer’s website:
Koala Bottle is The Magnetic Bottle (TM) that attaches to your bicycle, tethers to your aero bars and much more.
Koala Bottle is designed for safety and ease of use! The magnetic ring on the bottle provides 360° of contact and is designed so that you can easily drop the bottle into the cage when you are finished drinking. When you hear the ring click and engage the magnets you know that the bottle is firmly attached.
A magnetic bottle, you say? Why, didn’t another company try this a while back? And probably a couple before that? Yes…the concept has been tried before, and while the idea has its merits, most of the previous incarnations were hamstrung by proprietary bottles or other glaring problems. Not so with Koala Bottle — they really seem to have this thing figured out!
First off is Koala’s choice of bottle — the industry-standard Specialized BPA-free bottles with a soft, high-flow valve. They are branded with the Koala logo. No proprietary bottles here — so if you lose it or the bottle becomes uncleanably funky, you can toss it and replace easily (more on that in a bit).
Second is the cage itself — it’s of a fairly minimalist design, with stubby arms to help support the bottle. Up near the top of the cage are two very strong magnets that cling to the steel ring around the bottle itself when the bottle is inserted/dropped into the cage. Koala thoughtfully molded the cage with holes and long slots (and even provides longer-than-usual mounting screws) to fit almost any bike with brazed-on waterbottle mounting points. You can see the magnets and the mounting options in this photo:
Back to the bottles for a bit — the secret is the steel ring that fits around the neck of the bottle.
Koala sells replacement rings or complete bottles…or you can install the original one onto any standard Specialized bottle by following these quick steps:
Pretty slick, eh? Those Specialized bottles are everywhere, too — many bike shops and companies who have their own branded waterbottles start with Specialized “blanks”.
For those of you who might be concerned with the retention aspects of the magnetic cage, fear not. I filled up a bottle and rode my mountain bike up and down local stairways, curbs, deeply potholed streets and other urban hazards. The bottle never once shook loose. In fact, the magnets in the cage are so strong that an empty bottle is a bit of a struggle to remove from the cage! When it’s time to replace the bottle in the cage, you don’t even really have to line it up…just get it in the vicinity of the cage and let those powerful magnetic fields do their thing. Snap! This is definitely a benefit when you’re sipping in traffic on your commute; the last thing you want to do is fuss with your bottle.
Why would someone choose such a bottle system? It doesn’t really save weight; the cage comes in somewhere around 55 grams, which is a bit heavier than other plastic cages and similar in weight to typical aluminum/steel cages. Where this system shines is on bikes with limited clearances, like on small frame sizes. Since the bottle can come out of the cage sideways, no clearance above the bottle is needed. This also shines in the offroad world, when frame triangles on suspended frames are too tiny for traditional waterbottles and cage systems.
The Koala bottle is designed and manufactured right here in the U.S., and sells for $27.99 (21 oz size) or two dollars more for the 24 oz. size. Not a bad deal at all. This system definitely has a home on a couple of my bikes — I am sold on the concept!
