Is he neutered? If he's not, this is the single most effective way of reducing this behaviour, which sounds to me like classic, frustrated, hormonal bunny behaviour!
Does he actually aggressively bite you or is it just nips? Nips can just be a way of the bunny communicating with you (more specifically bossing you around!) My bunny Tilly who is sadly now waiting for me at the bridge, used to nip us before she was spayed as a demand for a stroke or just to move us out of the way! Once spayed she completely stopped it and other destructive behaviours like digging and chewing our clothes. If hes nipping you when you pick him up its just his way of saying I want to be put down! I only pick my buns up when absolutely necessary, they come to me when they want some love.
So my advice is if u havent already, get him neutered. It will make for a much happier, even tempered bunny.
If he is neutered, he's obviously just a very feisty dominant boy (endearing but can be a pain!) The best thing to do is try not to react when he nips you as this is giving him the reaction he wants (hard when you've been bunny nipped I know!) and hope he eventually gives up on it. He might just be a digger aswell, as many are as this is a natural thing for them to do. Provide some safe things for him to dig at, like a box of shredded newspaper or soil. You dont want him chewing fabric too much as the fibres may upset his delicate digestive system.
I hope this helps you out abit.
Good luck!
