Kickstands

Post by E-HP » Jan 02 2021 2:50pm

My kickstand finally gave up and snapped in half. It's the chainstay mounted type that I prefer, since it doesn't interfere with the pedals when deployed. The weak point is that it's a two piece design meant to be adjustable, which introduces points of failure that wouldn't be an issue with a single piece design.

I see two designs among the limited choices, the first being what I've been using:
https://www.amazon.com/dp/B08LS482TN/re ... s9dHJ1ZQ==

And the other having an additional support arm, but seemingly thinner stand. It's still two piece, but possibly less prone to braking. I ordered one, not anticipating that it will be durable, but just to I have something.
https://www.amazon.com/dp/B07WDT7P4N/re ... NrPXRydWU=

I checked the build thread pics and based on that, it looks like only 20% or so of the bikes has kickstands. Sort of makes sense, since very few full suspension bikes accept one, but even the hard tails seem to be missing them. Anyway, curious to see if these are the only games in town for a chainstay mounted stand. Not looking for the centerstand type.

You say that, but using a sidestand on a bike that's much heavier than intended was what caused it to break. If you stand the bike straight up, the stand is much more capable of taking the weight.

A bike does stand fine when it is upside down, if it has a wide handlebar especially. That is what I do with mine, when I don’t just lay it down. It does draw a lot of attention but go figure, bike thieves seem to have absolutely no interest for a bike that is upside down, even if it is unlocked and has a helmet and gloves on the crank. :mrgreen:

If you find this too weird for you, look for Motocross or Enduro kickstands. I remember one that was clamping on the swing arm, that you should be able to adapt.
Make it fool-proof, and I will make a better fool.

With a bike upside down on its seat/handlebars I find with a read hub motor that it can be a hassle because there is no weight up front to hold the bike down and the bike tends to lift from the handle bars more easily. Easy to fix in the garage because you can shove a handle bar under a tire, or place something on the handle bar.

I've never been able to find a good kick stand. The BB style of kickstand: I've seen the 2 leg style (one to the left one to the right) but when riding both legs go to one side. Then theres the 2 leg style that stays on either side. I've had good luck with chain stay AND BB kickstand for top heavy ebikes with battery ontop of rear rack.

Ursus Jumbo is the best two-leg, center mounted kickstand around. It's rated for something like 175 pounds, and it opens to about 18 inches across.

That is how you know the weight distribution/geometry of your bike is wrong. Fit batteries more forward, and/or more batteries, to compensate the weight of the hub. Stretch the wheelbase, slacken the head angle, shorten the front suspension travel, tune your cockpit to the front...
There are many ways that can be used and combined to achieve proper balance, and it will make your bike a better ride.

Well at least shipping was fast. Even though this design looks less sturdy, the leg is actually one piece cast aluminum (or mystery metal), with no obvious points of failure. Cheap enough that if it fails, it's easy and fast to replace.

I failed to notice how janky your original kickstand was.

This is the industry standard rear kickstand in the USA, by Greenfield:

It costs about 20 clams and like other Greenfield stands, it just works.

If it's helpful, some years back I was given one that looked almost identical to those to use for DayGlo Avenger at one point...the bottom "adjustable" piece is plastic that fairly loosely fits over the cast "alloy" leg, and it wiggled a lot even when I first handled it, later breaking and having to be glued on to not just fall off while riding. The farther out it must be adjusted to, the more load is taken by the hollow plastic part and the sooner it breaks.


The cast mounting bracket that the leg pivots from has a metal (possibly steel) pin or screw (can't remember) that acts as the hinge pivot, but the stress isnt' placed directly thru the line of the pivot, it's kind of a twisting force and eventually broke one side off of the bracket, in a line with and thru the hole for the pin/screw.

The frame clamps never held properly, so I'd have to retighten it jsut about every ride.


I had a few similar types, including one like the one Chalo posted, which also broke at the pivot on the bracket, and none of them were very good or useful on anything other than regular lightweight pedal-only bikes (and not ones used with any kind of cargo).


The only one I ever got (that I didn't make myself) that worked and didnt' break was a two-leg like an upside-down U with little feet/bars sticking out from the bottom of the U legs. (though likely most of the fixed two-leg types would've worked ok)

Yup, I can see the plastic foot as being the weak(est) point. I may have some tubing lying around that I can use to make a permanent foot from. I can epoxy it in place or use set screws, or both. As it is, the chainstay seems low enough that the plastic foot doesn't need to be extended much, and have the bike pretty upright (a lot more upright that the old kickstand). The extension/support arms appears to work, compared to the old one that only relied on clamping to the chainstay. I think if I locktite the bolts it might hold them. I'll do that for now, and use the plastic foot until it fails.

Welding would be ideal but not many home gamers have a personal welder to use, maybe ask your friends, or hit up one of those DIY mechanic garages as they always have welders to use.

I don't think epoxy would work well alone.

I would try to think of something that can wrap around the metal part stub of the kickstand but yet still give you the length you need, almost like any sort of pipe. Hit up your Homeless Despot store and see whats available in the aisles. Pack that metal epoxy in there and throw on some fasteners.

Galvanized Pipe would be heavy but strong. 1/2" seems all they have in shorter ID sizes, might be to big for the stub.

Well looky look, I see Homeless Despot's got 1/4" galvanized. Thats the ticket, if it fits!

I lengthened a kickstand leg with a left over scrap of copper water supply pipe. Its inside diameter was a good fit with the leg's tapered outside diameter.

Yeah I looked at that $80 Ursus Jumbo kick stand and it does look very strong indeed.

Some of the cross country riders have mentioned how they love the collapsable stick (tent pole) method of a kickstand when they are loaded up.

Yeah I do it that way to change a tire as I was getting lots with rear hub, but I dont get any flats any more still using bicycle components with a fork hub motor. There is still a problem, the 26x3.50 Chicane Vee rear tire doesnt look beefy or strong, had a hairline tube flat weeks ago I patched.
I still want to go motorcycle tires which are mostly out of stock (on the online motorcycle catagloge websites) for the longest time and its hard to find the size, width and tread I want. I can find used rims easy, and new hd (3mm) and uhd (4mm) tubes are plentiful.

My new conversion bike has a really good kickstand, with its own mounting plate right next to the chain stay cross member.

When I got the bike and subsequently had the hairline hole in the tube I had to take the rear wheel off. When I did so I noticed something fell onto the ground and never paid much attention to it. I later learned the previous owner had shoved a cut off bolt into the slot to lift the rear wheel up so the 160 disk wouldnt hit the no name caliper. Not only that, the rear hub is much shorter then the rear dropout by 20-25mm. Rear dropout is 180mm, I couldnt measure the rear laced hub and most bicycle stores are of course out of stock. It shifts just fine except for the granny gear, brakes just fine. 21 x 3.00 is the goal with uhd tubes.

So far the cheap $18 kickstand is holding up pretty well, even with the cheap plastic foot. I think it's mainly because of the extension piece that keeps the stand from twisting on the chainstay, and leaning over too far. I figure at 5 months of use, it's close to getting my money's worth out of it. :wink:

When that wears down try a rubber crutch tip (you can get them in various inside diameters).

Good idea.

Along those lines, adapting one of these might conform with the terrain better, and probably even works in sand too. Might be overkill.

On pedal forward bikes I've had good results with a center stand that retracts both legs to the side away from the chain.

I like that one. I need to see if it will work with my frame.

How is it off road or on uneven terrain, and does it clear the cranks when you spin them backwards when the stand is deployed?

Yeah it clears, the one leg rubs up on the other to it wears over time and the paint rubs off a tad.
Not sure what the tire width limit would be but I've had 2.20 clear just fine. You have a bit of wiggle room by rotating the kickstand.

Yeah I use a similar one and it works great for mountain bike trails. It doesn’t bounce around at all. And it’s super sturdy for heavy E bikes

Why not use two kickstands, one at the crank and one at the rear axle?
