>>1992580>building a nice diy bike stand?Does 'nice' mean 'looks good' or 'works'?
I'm gonna assume you think something like a Park stand is too expensive for what it is. There's two cheap ideas that I've seen, that I think are reasonable.
1st, if you have an exposed rafter (garage, porch, basement, etc), you can just use a piece of string. Either loop the string over, or use an eye bolt, etc. One at the saddle, one at the handlebars.
I think most people dislike this, because it's not absolutely fixed/your bike can swing a bit. Kind of the formal version of hooking the nose of your saddle over a tree branch.
2nd really cheap way is to make a tubing block, like what you'd use to hold tubes when building a frame. Tends to be some kind of hardwood, where you bore out the correct size hole (holesaw, auger, forstner bit), then saw the block in half & put a 'hinge' on it, usually a bit of leather. Then you clamp this block to/in something.
It's low-tech, but assumes you have some round tube on your bike (seatpost?) to put it on. Not my pic.
I used to ride with a guy, he had one of those basement screw jack pillars, and he made a block to fit the pillar, one to fit his seatpost, and used two wood clamps. There's a bit more to it, but you get the idea. He was 6'3", and the ergonomics were surprisingly good.
