In my altogether insufficiently humble opinion, the only way you could have too much bike is if it were the type with a motor. In that case "Too Much Bike" would mean that the power of the bike is too much for your weight/handeling skills - which is dangerous.
"Too much bicycle" is a different matter, and not a matter for worry.
The real question is, as I have often said before, is: Does the bike make you smile? If so, it's right for you. In the end, what else really matters?
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
