I bought a track pump from Aldi for £4.99. It worked fine for a few weeks, then the hollow tube that contains the plunger came free from the base. It had been hot-melt glued in. I briefly considered taking it back for a refund, then even more briefly considered getting out my hot-melt glue gun to fix it. Then I came to my senses and bought a Topeak Joe Blow track pump for £20.99, delivered from CRC. That was four years ago and it is still working flawlessly.
There is quite a lot less to go wrong with a maintenance stand than a pump though. Personally I am yet to see a workstand that can’t handle an ebike, despite it being one of the most asked questions here; sure some of the fixtures and fittings (like the jaws) can be of better or worse quality, but they all seem overbuilt enough that a 25kg load is well within their capacity.
I didn't see it as a matter of "there is less to go wrong". (In fact there are probably fewer parts in a track pump, but that was not my point). I was pointing at the design of how it is made and the quality of manufacture for something that is built down to a very cheap price rather than to a "fit for purpose" spec that happened to be on sale.
I bought a similar cheap one and the only issue with it is the middle clamp that enables the height to be adjusted does not grip particularly well...but easily fixed. I use it at the same height each time so I drilled through the 2 upright sections and put a 10mm bolt through...no nut so if I want to adjust it lower I can just pull the bolt out.
Just make sure the clamp is clean if you're clamping it onto a dropper seat post. I put a micro fibre cloth in the clamp too. Just to protect the sanctions from scratches. Plus an ebike is a lot heavier to hold on the seat post. I prefer it the way dave has it. Just don't clamp it up to hard
