It was raining in the morning so I didn't commute on my bike (I know, coward,
slacker)
However, at noon I noticed it was dry out so I took out the 40+ lb Worksman shop bike and rode 6 laps around our building (2 miles) at top speed.
if anyone here thinks they need a fancy road bike to get good exercise,
think again. That old cruiser gave me quite a workout! and I must have been going all of 10 miles per hour! gasp. no kidding.
and when the wind comes up, You REALLY feel it.
