Building/buying my niece a bike

I'd avoid a coil spring fork on a kids bike. They add weight, will stop working and don't work great to begin with.

This looks ace. Air sprung, hydro disks. Looks rad. http://www.cyclelane.co.uk/m5b138s10p11714/ORBEA-MX-24-Trail-2018/RS_GB/51203

Or, without the fork is very nice too and a touch cheaper.

Just bought my eldest the 20 inch version with rim brakes for xmas. She's mega excited for a "gears bike". In hoping it's the end of me pulling her up hills.
