20 Inch Bike Kickstand for Kids Bikes and BMX
The 11.0 in Kickaroo leg, the longest of the five. Painted steel body, rubber foot, one bolt through the rear chainstay. Read the BMX section before you order.
Description
This is the longest leg Kickaroo makes. The 20 inch version measures 11.0 in (28 cm) from the mounting plate to the tip of the rubber foot and weighs 5.6 oz (159 g), which puts it 1.0 in longer than the 18 inch stand and 3.7 in longer than the shortest one in the range.
Everything above the leg is shared with the other four sizes. The plate is painted steel, 3 mm thick, measuring 0.98 x 1.65 in (2.5 x 4.2 cm), with a single mounting hole of 0.41 in (10.5 mm) that accepts a standard kickstand bolt of 0.31 to 0.39 in (8.0 to 10.0 mm). It is a side mount, which means the plate sits flat against the rear chainstay and the leg swings down on the left of the bike. The foot is rubber.
At 20 inches the bike is no longer a toy in the way a 12 inch bike is. It is heavier, it often has hand brakes and a real drivetrain, and it goes on longer trips where it gets parked away from home. That is the case this length exists for. It is also the length where the fit question gets more interesting, because 20 inch frames vary far more than 12 inch frames do, and BMX frames sit in a category of their own.
One practical note before the bike is on the bench: the stand ships without a bolt. Two separate buyers have reported it, and one of them wrote that his package was simply missing the screws to fix it. A standard kickstand bolt passes through the 10.5 mm hole, so the missing part is cheap and easy to find, but it is not in the bag.

Check your BMX frame for a mounting point before you order
This is the honest version of the BMX answer, and it is the reason this section sits above the sales copy instead of below it. A side-mount kickstand is not a universal part. It needs two things from the frame, and a bike that lacks either one cannot take it no matter how long the leg is.
The first requirement is a flat landing. The plate is 3 mm of steel measuring 0.98 x 1.65 in, and it has to sit flush against something. On a typical kids bike that surface is the short bridge or the flattened section of chainstay just behind the bottom bracket. On a round-tube BMX frame there may be nothing flat there at all.
The second requirement is a hole. The plate carries one mounting hole of 0.41 in (10.5 mm) and the bolt has to pass through the frame or into a threaded tab. If the chainstays are sealed round tubes with no tab and no hole, there is no way to attach this stand without drilling a frame, which is not something we will tell you to do.

The two minute check
- Turn the bike upside down, or lift the rear end onto a stand, so you can see the area right behind the bottom bracket shell.
- Look for a flat tab with a threaded hole, or a flat plate bridging the two chainstays with a hole through it. Either one is a mounting point.
- If a previous owner removed a kickstand, the empty threaded hole will still be there. That counts.
- If you see two round tubes, nothing flat between them and no hole anywhere, this stand has nothing to bolt to. Stop there rather than ordering and hoping.
There is a second thing worth saying plainly. Riders who use a BMX for jumps and park sessions generally remove kickstands because a leg that unfolds mid-air is a hazard and because every ounce counts on that kind of bike. This stand is built for a 20 inch bike that gets ridden to school and parked outside it, not for a bike that spends its afternoons on a quarter pipe. If your child rides both ways on the same frame, that is a judgment call you make rather than one we can make for you.
Bikes with knobby tires and suspension forks raise their own set of clearance questions, which we work through in the mountain bike kickstand guide.
The trap at 20 inches: the longest stand is not automatically yours
That buyer wrote up what he did, and it is the single most useful account in our feedback on this size.
Got the 18 inch kickstand for a 20 inch kid's mountain bike and it worked fine, since some reviews said it was too long. Sizing is tricky to gauge but I knew 20 inch would be too long. I had to install it on the inner part of the seat stay since there was a protruding metal bump that prevented me from installing on the outer part, which would have been preferred. In any case, I got it to work.— Verified buyer, 18 in stand on a 20 in bike
Two lessons sit inside that paragraph. The first is that wheel size is a starting point rather than an answer, because the height of the mounting point above the ground is what actually decides the length you need, and that varies with tire depth, frame geometry and how the chainstay is angled. The second is that the exact spot on the frame is negotiable. He could not use the outer face because of a metal bump, so he moved to the inner face and got a flush landing there.
| Wheel size | Stand length | Weight |
|---|---|---|
| 12 in | 7.3 in (18.5 cm) | 4.9 oz (139 g) |
| 14 in | 8.1 in (20.5 cm) | 5.1 oz (144 g) |
| 16 in | 8.9 in (22.5 cm) | 5.2 oz (146 g) |
| 18 in | 10.0 in (25.5 cm) | 5.5 oz (155 g) |
| 20 in (this page) | 11.0 in (28 cm) | 5.6 oz (159 g) |
Take the measurement before you choose. Stand the bike upright with both tires at their marked pressure, find the flat spot behind the crank where the plate will sit, and measure straight down to the floor. Then read that figure against the table. The 18 inch stand at 10.0 in and the 20 inch stand at 11.0 in are only an inch apart, and on a 20 inch frame that inch is the whole decision.

Fit is the recurring theme across every length we sell, which is why the sizing page exists as its own guide. If your measurement lands between two sizes, read what size kickstand for a kids bike before you order, and see adjustable versus fixed bike kickstands if you would rather have a leg you can reset later.
Bolting the 11.0 in leg onto a 20 inch frame
A 20 inch frame gives you more room to work than a 12 inch one, which makes this the easiest length in the range to fit. Use that room. Try the plate on the outer face of the chainstay first, since that is the position that keeps the leg clear of the drivetrain, and move to the inner face only if a weld, a cable guide or a molded bump gets in the way, exactly as the buyer above described.
Angle matters more here than on a small bike. A longer leg on a taller frame means the bike carries more weight further out from its own center line when it is parked. Set the leg so the bike leans a little rather than standing almost vertical, and test it on a slight slope in the direction the bike will actually be parked, which for most families is a driveway.
Add a drop of thread locker on the bolt while you are there. A 20 inch bike gets kicked onto its stand hard and often, and one bolt takes all of that twist. Check it after the first week, then whenever you check tire pressure.
The full sequence, with the clearance checks written out in order, is in how to install a bike kickstand. If you are still weighing up whether the part earns its place on a bigger kids bike, do kids bikes need kickstands makes the case in full.

Where it falls short
Three things show up often enough in feedback to belong on the page rather than in a support email. The stand arrives without a bolt. The return spring does not always carry the leg all the way back up on its own, and one buyer of this exact length said he helps it into position with his foot. And the rubber sleeve on the foot can work loose over time, which one buyer solved with glue and described as a non-issue afterward.
The fixed length is the fourth thing, and it is the one that costs money rather than patience. There is no adjustment once the stand is bolted on, so the measurement you take before ordering is the whole game. Everything else on this list is something you settle at the workbench.
What buyers of this length report
"The footrest attaches without issues, the children's bike does not fall."
— Anna A., verified buyer, 20 in
"Although it doesn't have a strong spring that folds it all the way once you remove it, you have to help it with your foot to get it into position. Otherwise it's fine, normal. For me, a 20-inch wheel was the only option."
— Verified buyer, 20 in
"Arrived safely on December 8, 2025. Too bad it's missing the screws or bolts to fix it."

Questions people ask about the 20 inch stand
Will this kickstand fit a BMX?
Only if the frame has somewhere to bolt it. Plenty of BMX frames are built with no kickstand tab, no flat plate between the chainstays and no threaded hole, and riders often strip a kickstand off rather than add one. Turn the bike over and look behind the bottom bracket before you order.
Does a 20 inch bike always need the 20 inch stand?
No. One buyer deliberately chose the 18 inch length for a 20 inch kids mountain bike after reading that the longest stand can sit too long, and it worked on his frame. Measure from your mounting point to the ground rather than ordering by the number printed on the tire.
Does the 20 inch kickstand come with a bolt?
No. The stand arrives on its own and two separate buyers have flagged it, one of them noting that his package was simply missing the screws to fix it. The plate has a single 0.41 in (10.5 mm) hole and a standard kickstand bolt passes through it, so source the bolt before you start.
Does the leg fold back up on its own?
Usually, but not always. One buyer of the 20 inch length reported that the spring on his unit did not carry the leg all the way back and that he had to help it up with his foot. The stand still parked his bike normally. It is a nudge with a shoe, not a repair.
What if my 20 inch frame has no flat spot on the chainstay?
Then this stand has nothing to bolt against, and no amount of length will fix that. A side-mount plate needs a flat surface and a hole. If your frame has neither, a rear-axle mount stand is the style you need, and that is a different product from the one we sell here.
