My twins will be 6 at the end of next month and want bikes. Went to the bike shop today to see what size they need and they need 18inch bikes. The bike shop man said it's a bit of a job getting stabilisers on these size bikes and said not to bother as they should be able to ride without them soon enough. So i am just wondering what age your children were and whether you think it would be worth be getting stabilisers added? Thanks
