Evil bike..?

[Popoki_Nui]

I think i'd have a good fiddle with the saddle if i were you...not sure what else to offer, except that my bike too is evil. In a slightly different manner though...it did this to me last week.

Ouch! What happened??

edit: I have indeed adjusted the saddle (and replaced the one in the pic). For some reason, the bike just does not want to roll)
