I've used this forum as a tool for the past month or so as I researched buying a commuter bike. I finally found one I liked on Craigslist at a good price. It's a Novara Buzz. The previous owner commuted 6 miles each way through downtown from the M streets and upgraded a few parts. Mainly:
Nexus 7 speed internal hub
Schwalbe Marathon Plus tires 26"
I'm buying some accessories soon that this forum helped me pick out:
Planet Bike Blaze 2 Watt
clipless soon (SPD?) the pedals are just platform!
I haven't ridden a bike in 3-4 years but I'm in average shape for my age (22). I just returned from a 12 mile refresher that took me a third of the way down my commute and back. My final commute will be 18 miles each way down the white rock lake trail and back. It will be gorgeous at 6AM and hot at 4PM but I'm hoping I can commit to it as now I have the resources.
I'll be moving in September to Plano so if I really enjoy this whole bike commute thing I will probably upgrade my ride to a speedy road setup as my commute will then be 25 miles each way on 100% road.
Anyway, I enjoy posting and will continue reading.
