Kid’s new bike day

My daughter’s Vitus has 7 speed Microshift on it rather than Shimano. Works ok – but she only just showing interest in changing gear do I’ll probably know better in the next month if she can reach both.

I think the hub isn’t a standard freehub setup – I think it’s a screw on freewheel.

Son1 (aged 6.5) has a Vitus 20+ with microshift 7, he spends most of his time in the easiest gear as we have hills all around us. he gets on ok with it but has to think about his gear changes.
