Ok, so before I get into it I'll be totally honest. Most of my riding over the past few years has been commuting on upright bicycles. I have gone on a few longer (more than 100 miles) trips, but they were on my road bike and were pretty painful after mile marker 40 or so. Now I have a V2K conversion setup like a road bike. Over the past few days I've learned how to ride in a straight line, negotiate tight turns, and (most recently) start by pedaling. Last Sunday I decided to go for a ride around town. I noticed two things immediately. First looking around while riding is way more fun if you're not craning your neck. Second, plant your back against the seat and these things move ! By the time my knees started to ache a bit (fit is good, maybe the cranks are too long or I'm just not in shape yet) I had cycled more than 20 miles in an hour and 10 minutes. I had to double check that distance with Google maps when I got home. I know that's not a record-setting pace, but for this Mega-Clyde to have accomplished that with only a twinge of knee pain is remarkable, trust me. So add mine to the list of converts and testimonials. I'm convinced. Now I just need to gain the confidence needed to tackle the high rise bridges to test their climbing ability. I've heard that it's passable.
