I have 2 very very good condition hot rock 14″ in the pink/purple colour for sale. Was going to put them on eBay but would take £60 each if interested. Just to counter the arguments above the 16″ may be the similar height but it is much more stretched out/longer. My daughter has taken 6 months to get to an acceptable size to ride the 16″ and even then it borderline and she can’t do half the things on it she cannon the 14″ which is why we were keeping both.
Sadly my son wants a bmx so after buying 5 hot rocks over the years it is stopping now.
At £60 you could use it for 6mths plus then sell for not much less
