I’ve got a spherovelo. 18 month old had it for a while now, she loves being pushed about on it, she loves standing behind it and pushing it about, but she struggles to actually move it along by herself when sitting on it, it always tips forward. She’s slowly getting better. She knows when I take the stabilisers out of it though and she doesn’t like it!!
It’s ok, I definitely wouldn’t pay full price for one, think I paid about £35 from EBay. Haven’t got anything to compare it to as an alternative. I’d like to see her on a proper balance bike asap really.
