What type of kickstand do I need? (Screw ‘up’ centre mount)

[AllRides]

Centre kickstand mounting

I have a Raleigh Motus Tour with Crossbar which means I have a centre mounted one-leg kickstand. I want to go to a double leg for kid-carrying/stability reasons but all the kickstands I can find mount ‘down’ - that is to say that the bolt goes from the top in to the kickstand itself.

But the current kickstand (see very muddy image) bolts up in to the frame.

Can anyone clear up my confusion? Is there a different type of kickstand I need to look for? I can’t find anything that works in this configuration.

Thanks!

I would say your configuration in the photo is somewhat less common.
What does your current upward facing bolt screw into? - a plate (part of the stand) that sits on top of the chainstays, or does it thread into a plate that is part of the bike frame? I would have said it is likely to be the 1st option, and unlikley ot be the 2nd option.

If the bolt screws into a plate that is part of the stand, you mount a twin leg stand in the same manner as your existing stand, but the bolt faces down and screws into the stand under the chainstays,
If the frame was threaded, then you could screw a bolt from above through the frame plate and make it tight, put the stand underneath and secure it with a nut on the bottom of the bolt. A Pletcher stand won't let you do this, as the bolt hole is closed at one end. Another make (Hebie) will allow you to do this, but when the stand is up, on some bikes the legs foul the lower part of the chain.

I have a twin leg stand (Pletcher), I don't use it as much as I thought I would. If there is something to lean the bike against I do that, because when I use the twin leg stand, the steering flops round.

This part of the bike gets lots of water/salt (in winter) thrown at it, the stand is likely to be aluminium with a steel bolt. Grease the threads well to prevent to bolt corroding up solid.

A couple of examples (other examples on the SJS website)

The Plecher stand finish (polished) corrodes remarkably quickly in the presence of road salt (and becomes a sort of matt grey).

I have seen a few bikes with 'bolt up' mountings and it is easy enough to convert a single leg stand or the frame to the more usual 'bolt down' style or even a 'through-bolt' style by drilling the threads out of one piece. Twin legged stands are trickier. However, conversion might not be required here, because I think your stand is actually 'bolt down'; that is what your photo looks like to me, anyway, Possibly the bolt head is a style you are not familiar with; in any event a photo from above should clinch it.

[AllRides]

Thanks for the replies. @brucey I have attached a picture from above but it doesn’t help because the frame is sort of ‘sculpted’ (annoyingly, it just makes the bike look bloated in my view).

If there's a manufacturer label on the current kickstand you could search for them and see if they do double leg version. The Pletcher snd Massload stands all seem to be a top down bolt design with the bolt screwing into a large threaded enclosed chunk of aluminium. That bottom-up bolt design looks to be rather bespoke.

I have one of those Swiss made stands too, took me three attempts to remove just the right amount from the legs to get almost four points of contact with the ground, that should stop the floppiness.

I may be able to help with floppiness in other areas too, feel free to contact me via pm for more advice.

Centre kickstand mounting

I have a Raleigh Motus Tour with Crossbar which means I have a centre mounted one-leg kickstand. I want to go to a double leg for kid-carrying/stability.............

In a previous thread you mentioned carrying a 7 year old in a rear seat.
I think thats a bad idea for all sorts of reasons, as did several responders to the thread.
Any bicycle stand won't safely support a 7 year old in a rear seat while you get on the bike.
Your photos appear to show an alloy frame, immediately adjacent to the kickstand plate there is a hole in the chainstay for an internal brake pipe; I think thats a failure just waiting to happen.

Thanks. I’m interested in the Alloy point - what makes it so susceptible? The bike and stand I have been looking at are rated >80kg which should be more than enough I thought?

[531colin]

Alloy is generally considered to be “not good with fatigue” ; and fatigue cracks start not in the middle of a straight tube, but at “stress raisers” such as welds and interruptions in the tube…. But several forum members have much more experience of this stuff than me.
What does “rated<80kg “mean?
Bikes are often rated 100kg …that’s the rider, the bike and any luggage; most of the weight being the rider whose weight is distributed between saddle and pedals.

[AllRides]

Rated >80kg meaning that the items are both rated to take above 80kg. I don’t intend to sit on the bike on the stand of course but the stands I have been looking at have stated being able to take 80kg+

Hopefully that’s clearer! Thanks.

[531colin]

My guess for the stand is it means the stand will take a static vertical load of >80kg. But not a moving or non-vertical load.
But for the bike I have no idea. Adult riders will usually be over 80kg. I can’t believe it’s rated for 80kg of luggage or the stand mount will support a load of 80kg.

I really appreciate you taking the time to respond but I’m struggling to understand how the load of the stand is relates to my question about fitting? Clearly I the stand will only be used when not moving….

I thought that was probably about a child in a seat, as upthread...

............... I’m struggling to understand how the load of the stand is relates to my question about fitting? ............

Well, you ask very specific questions....
What bike seat for a 7 year old?
What stand for my Motus?

The question I'm answering is ..........."Is it a good idea to put a 7 year old in a bike seat on the back of a Raleigh Motus?"
.....the answer is "no"
.....because with the weight of a 7 year old out over the back wheel, the handling will be so awful you won't ride it
....because the bike isn't constructed to take the weight of a 7 year old in a bike seat
....because no bike stand will support a child in a bike seat

...........how the hell would I know? well, this is me and my kids, I think that was the day our (now) King Charles III married Diana; it was declared a public holiday.
