What size bike for dd11? Help, quick!

[Howmanysleepstilchristmas]

Dd11 would like a bike for Christmas. She’s about 4’11”. I’ve got a Littlewoods code, which expires Friday so no time to take her to try bikes as she’s at her dad’s. What size do I get? Which bike? Adult or kids? No idea where to start... help please!

The halfords site tells you which wheel size you need for which height.

So is the rest of the bike a pretty standard size then? Will have a look...

Have text XH to ask him to measure her!
