This may or may not be useful for someone so thought i'll post it.
I just got my oldest daughter a Beinn 20 large (which is awesome btw) and now want to upgrade my youngest daughters bike to an Isla too. Both started out on a FirstBike and then moved on to a the Puky Z2 (both bought for my oldest). The FirstBike is a great balance bike and was well worth it's money although not so sure about the Z2. The Puky feel very heavy and both girls have been struggling with even the slightest inclines. Anyway, it is time to upgrade the passed down Puky but i couldn't make up my mind between a Cnoc 14 and 16 so decided to mock up a visual comparison. It's probably not 100% accurate but should be pretty close (based on saddle and wheel size).
Hope it's of use to someone..
