Dj / free ride for big fella

[Awakener]

Hi all

 

So a month ago I got my son a trek jack 2 DJ. He loves it and I must admit I got hooked on the idea of hitting the pump tracks and free ride trails with him. Now I am 195cm and clocking on 123kg.

 

I am a complete newbie to mountain biking so need some advice on what would suite me. What I have so far is that it should be hard tail, was recommended I use a GIANT frame and stick to 27.5 or 650b for DJ and free ride.

 

Any guidence or recommends would be greatly appriciated. Also I don't own Google so not looking to spend a mint to see if this is a hobby I would like to pursue.

 

Was given the name of Robert Frost who can help with the wheel setup up buy that's about all the knowledge I know ha ha.

 

Thanks all in advance.
