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?
