Islabikes are OK but not amazing.
Depends what you want.
If you want bragging rights, and the ability to say, “Well, we took our little darling’s cycling seriously, I mean, who wouldn’t? Of course we got an Islabike. They’re just so much better, aren’t they?”
If you want a great kids bike and don’t care about the bragging rights, get a Ridgeback. They’re ace!
(Disclaimer – Little Miss CFH is currently shredding the gnat on a Specialized Hotwalk. Preferred it to the Ridgeback Zoom as it’s lighter (for carrying home!) and doesn’t have a brake, which I find speeds up speed and spatial awareness)
