What material, and how does decals, grips, bar tape, saddle etc look? A steel frame will be pretty much unconcerned up to the point of basically getting the paint scorched off. Aluminium frames sometimes undergo extensive heat treatments after manufacturing and may soften enough to change significantly even with the paint left in place. Even CF is routinely cured at elevated temperatures, and may well survive more than imagined.
If there's a decent insurance clause on the garage, I might try to get the bike replaced through that, just for peace of mind. If it isn't, I'd probably ride any bike not showing any discoloration/deformation of plastic or rubber parts, but YMMV.
