How to use a stirrup pump on kids bikes - no space for chuck? My last bike experience was about 56 years ago. I now want to inflate the tyres of my grandchildren's bikes. I have a steel stirrup pump (floor pump) with presta and schrader orifices in the chuck. I'm in the UK, where everything seems to be schrader. I'm assuming the schrader orifice is the hole without a poppet.

Problem:  the chuck is too big to enable the lever to be extended when connecting to the valve on the wheel. (For an adult bike, the lever in the neutral position would be at right-angles to the valve. In the working position, it would be inline with the valve.) 

Question:  I read about "flexible extenders" in relation to kids' bikes. (In the old days, this thing lived inside the handle of a straight pump.) I'm wondering if a schrader flexible extender would do job? For example:

If the above monster link fails, this link might work:

If the answer to my question is "yes", do I simply push the left-hand end shown in the link into the schrader hole in the chuck, and extend the lever?
Sadly no - that short hose would have been used on an old-school frame pump, and yes, it would have been stored in the handle.  The host/pump thread is not the same size or pitch as a schrader.



The threads are not opposites, so that hose won't go into a schrader chuck.

Compare the end with these adapters - see how the brassy one looks like another schrader valve, and the topeak one looks larger?







Your other option is to simply lean the valve stem over a bit, and see if that gives you room to flip the lever.  The valve stem may tear off, more likely if its an old tube.   

Or since its the same as a car tyre, take the bike down to the local service station and use their air bowser to fill the tyre.  Not sure about your location but here most fuel station air pumps would fit fine on any little wheel's valve stem.
