if your not going to be going down hill off road going 40mph over jumps ect it will be fine just for riding round town ect
it wont snap in half as soon as you sit on it but you will find 120kg is the limit on most bikes same with office chairs ect.
plus you will loose waight fast i can live on takeaways and cider and still stay the same size
also note the frame has 5 year warranty, they dont know how fat you are if you did brake it so warranty wont be a problem if it even happens.
the wheels would fold in half b4 the frame broke.
