My son loved his LA Sports" balance bike but now it's broken was looking for a slightly bigger one hopefully to tide him over. His last one had 12" wheels, weighed about 3kg and max saddle height 42.5cm. Am struggling to find one that can be higher but also lightweight. I like the rubber tyres as he has a tendency to go over stuff which could cause a puncture. Also are brakes a good idea or not? Thanks in advance.
