I Need Your Help!

Myself and 3 friends have decided to embark on a challenge that we have talked about for many years.

It came about when I bought a full suspension MTB for a good few grand, and had a discussion with a work colleague who had just bought an equivalent (in his eyes) bike for about £120- full suspension MTB, that’s kind of where the similarity ended, but he was having none of it, and said how can my bike be worth best part of 30 times what his was.

This got me thinking, and hatched the plan. We each have to purchase a new, but very cheap, full suspension MTB from a legit source, and we are going to give it full throttle around Afan, doing Whites Level and the Wall initially. The desire is for the bike to break catastrophically before the end of the run.
We will be in full body armour and full face lids, due to the almost inevitable crashes due to component failure.

For me the best bit will be arriving in the Glyncorrwg carpark in my mates very cool sign written bike shop van, emerging in about a grands worth of clothing and lids each, then producing the Apollo, or Universals from the back and steaming off up the trail.

This is were I need the help, the cheapest adults dual suspension bike I can find is from Amazon at £89.99, is there anywhere else cheaper that isn’t some dubious internet deal from a shill company set up to part me from less than a ton yet supplying no bike.

I’ve checked Argos, Tesco Direct (they had a deal for £79.99 but I was too slow), Halfords and Amazon. Where else should I look?
