I don't like to eat meals that late. In fact nothing after 8 30 except either a protein shake or some cottage cheese right before bed ... and I'm usually asleep around midnight. Have you tried "halving" the meal? That is, have dinner prepared, eat half of it, go on your ride and eat the other half when you get back?
Also, is weight/metabolism an issue for you? If so then I'd really try and cut out eating that late, if not it's probably not a big deal. Either way you want that last meal to be as low in carbs/fat as possible.
... That all sounds really disjointed but hopefully it makes sense to someone else
