Edit last post – inside leg seemed out so we’ve done it again (properly!) – 67.5 cm which is more like it. So small 26 size then.
That makes a huge difference 😀
You’re pushing a XS adult frame …
Weeksy posted his lads just got a Whyte T403 (in fact we rode with them the day he got it)
would he be able to ride up a steep grassy hill with lumps and bumps and molehills on it?
Front sus won’t make much difference going up … (depending on the lumps) …. it can be a big help on stuff with roots/rocks on a trial though where it helps to just keep moving (but so are bigger wheels) but on an out and out climb it is more hinderance than help and that’s where you’d usually lock the suspension and it’s just extra weight. This is then dependent on the suspension actually working with a kids weight … which most (nearly all) are simply not designed to do…
After learning to ride that is.
I think you just need somewhere other than a lumpy field to learn….
My 7 yr old can “ride” my adult medium round a car park or over a flat field…. (but no way would he ride down a lumpy field except by luck)
Anyway … why not try a weekend hire ??? You could go to Grizedale or Kielder for example….
