We had a Hellion 20, the forks worked brilliantly and I sold it for pretty much the same price I bought it, maybe lost £20 on it. I may have been lucky with timing on a pretty brilliant bike that wasn’t produced in large numbers.
My daughter currently has a Kona Process 24, another brilliant kids bike with suspension that works. Following her down trails at places like BPW you can see the shock and forks doing their job at speed and generating grip on lots of sections I wouldn’t have thought a short travel bike could. It does remain to be seen how much I can sell the Process for, hard to tell as it’s very rare to see them for sale.
I’ve just bought her another bike for Christmas, I did look at the Vitus, but the Canyon Neuron Young Hero won me over on spec and value for money…
