I'd go for it, you'll be fine I would think. Haibike may take issue with any warranty claims if push comes to shove and they flat out ask you what you weigh but that's unlikely. As far as the bike collapsing under you, aint gonna happen. Provided you're not dropping 20' to flat on a daily basis. Just bear in mind you can wreck any frame or component if you try hard enough, no matter the perceived rating. You could always consider a more premium model if budget allows, that should have plusher or maybe longer suspension but just remember, the more you ride the closer you'll get to that 265lb limit and it wont take long.
