I have my pub bike but now I have a child seat on it I need a decent stand so I can get the mini me in and out.
Is there a decent but light stand?
You mean like a kick stand? No idea, I always used to just lean the bike against a wall/fence/tree/thigh/etc. You'll only drop them once or twice 😀
Strong or light - pick one. If it's a pub bike with the added weight of a child seat (and child) on it, then does the weight of the stand really make much difference?
For loading up (whether children or cargo), I'd say go for a twin leg stand. Pletscher would be the most-trusted brand to look out for, and probably the lightest, but cheaper, heavier ones are also available. I just used a cheap steel one from Halfords when running a tandem with two childseats. Weighed a tonne, but wasn't noticeable once fitted.
