OP, welcome to the New Forest…..no really, I mean you are welcome to it, take it, it’s yours, no problem….
In all seriousness, if you haven’t got a lightweight xc bike, hard tail, rigid or CX bike, you will do after you have lived here for a bit – you can get some serious mileage in, improve your cardio fitness, but you won’t shredding the gnarr anytime soon. If you want a bit more gravity, head to Dorset (puddle town woods, uk bike park or the purbecks)….
