I have two bikes. a 1988 Schwinn LeTour and a 2008 Trek Navigator I set up to commute. I love my Trek "Comfort" bike. I'm riding trails on the weekends and doing things I didn't imagine when I started two months ago. I've lose some weight, feel better than I have in years and gone from filling up my car once a week to once a month.
But I want to get up to group rides 40 to 50 miles and I need to go faster. I have tried using the old Schwinn but the seat height is higher than the handle bars and I'm really uncomfortable. Will that get better? I'm 66 years old, 6'4" and 265lbs. Should I be looking for something more upright than a road bike?
