What makes a good floor pump? There are so many options, mainly because of the own-brand alternatives. So how do I choose a good floor pump? What should I look for?
I'd say it must have a good sturdy build and should be stable.

It must have a good pressure control and display; it should have a proper pressure range.

It should have a good connector with detachable/replacable plugs.

It should have a long hose, so you're not too close to the bike and make full control strokes on it.
