There is a saying that "men are usually boldest before the fall." It looks to me like you already have a pretty bike friendly working environment. Don't push it or you may have more time to ride your bike than you had planned, if you know what i mean.

Some companies tend to look at some employees that have been around a long time as dead wood that may need pruning. Don't count your 20 years as more important than they might be. Sure you think it is a big deal but do they?
