DD1 is almost 5, and asked to take her stabilisers off. She's not used a balance bike - we did get one for her 3rd birthday but it wasn't great, and she's not outdoorsy, so we never got round to buying a different one. She got a bike with stabilisers for her 4th birthday and now we're trying without.
I don't think the pedals can be taken off, sadly.
We're holding her, rather than the bike, as I've read that's best - but she just leans on whoever's holding so heavily that we're getting nowhere and it's frustrating for everyone.
So, please hit me with your best tips to get us going - any advice appreciated!
