ABC Bottle Cage for Ebikes Standalone: The BEST Water Bottle Cage for Ebikes

We like to call this the best water bottle cage ever invented. Where the ABC Cage really shines is the adjustable fit: it holds bottles from 2 1/4" to 4 3/4" wide, so you can use the water or sports bottle you already own instead of buying a special size. An easy turn dial locks in a snug, rattle-free fit.

Why riders love the ABC Cage

• Fits almost any bottle. Adjustable from 2 1/4" to 4 3/4" wide, from slim water bottles to large sports and insulated bottles.
• Use what you own. No proprietary bottle required.
• Secure, rattle-free hold. Turn-dial tension keeps your bottle put over rough terrain.
• Standard bottle-boss mount. Bolts to any frame with standard cage bosses.

Riding an ebike with tight battery or frame clearance? Our side-loading Sidewinder cage is our top pick for ebikes, loading from the side where a standard cage will not clear. The ABC Cage also comes in a handlebar mount and an 18" strap mount for frames without bosses.

How to choose the right bottle cage for your ebike

Ebikes make bottle mounting harder than regular bikes do, usually for one of three reasons. Here is how to work out which cage you actually need:

• Start with your bottle, not your bike. Measure the widest part of the bottle you already own. The ABC Cage adjusts from 2 1/4" to 4 3/4" wide, which covers everything from a slim road bottle to a wide insulated tumbler. If your bottle falls in that range, you do not need to buy a new one.
• Check your frame clearance. This is the big one on ebikes. Battery packs, downtube shapes, and step-thru frames often leave too little room to lift a bottle straight up and out of a standard cage. If you cannot clear it from the top, our side-loading Sidewinder cage is the answer, and it is our top pick for ebikes specifically.
• No bottle bosses on your frame? Plenty of ebikes ship without threaded cage mounts. The 18" strap mount version attaches without any bosses, and the handlebar mount moves the bottle up to the bars entirely.
• Riding rough surfaces? Tension matters more than it sounds. The turn dial lets you snug the cage down to the exact bottle you are running, which is what keeps it from rattling loose on gravel and broken pavement.

Ebike water bottle cage FAQ

What size bottles does the ABC Cage fit?

It adjusts to hold bottles from 2 1/4" to 4 3/4" wide, which covers standard water bottles, larger sports bottles, and most insulated bottles. Measure the widest point of your bottle and check it against that range.

Will it fit my ebike if the frame has no bottle mounts?

Not this version, which bolts to standard cage bosses. For a frame without bosses, use the 18" strap mount version or the handlebar mount instead.

My battery is in the way and I cannot lift a bottle out. What do I do?

That is the most common ebike bottle problem, and it is exactly what the side-loading Sidewinder cage solves. It loads from the side rather than the top, so tight downtube and step-thru clearances stop mattering.

Will my bottle rattle loose on rough roads?

The turn dial sets the tension to your specific bottle, so you get a snug hold rather than the loose fit you get when a fixed-width cage is oversized for the bottle in it.

Do I have to buy a special bottle to use it?

No, and that is the point of the adjustable design. Use the water or sports bottle you already own, as long as it falls in the 2 1/4" to 4 3/4" range.

Does it fit regular bikes too?

Yes. It bolts to any frame with standard bottle cage bosses, ebike or not.
