It's a total of a mile and a half to two miles a day depending on which train station (different stations have different express trains and my start time may vary on different days). I might make it 2.5 miles if I decide to visit the library after work since the library is only a couple blocks from the A.H. train station and I've clocked it at 1.25 miles from home, although it doesn't seem like a quarter of a mile from the train station which I've clocked at about a mile. I must have an error somewhere.
The design of the bike is such that it's virtually impossible to hit my knees on the handlebars. It's just that despite the seat being all the way up I can't extend my knee all the way and it feels like I'm bending a bit far. The new bike is far more comfortable for my height too.
Thanks for the advice.
