Here is my newest addition to the commuter stable:
The 56cm Windsor Oxford from Bikes Direct
I bought my other two bikes at local shops, but had difficulty finding a basic 3 speed bike with a large frame. Most shops around here have cruiser style 3 speed bikes, and wanted to steer me toward derailleur bikes (which I already have two of). The shops that had commuter style 3 speeds didn't have one in stock that would fit my 6' 1" body. I ordered the bike on Tuesday morning, and received it by Thursday afternoon.
The assembly was simple enough. I added a Cascadia mud flap ($5 from Planet Bike), Ibera PakRak rear rack, lights and computer, and water bottle cage. I ordered a set of MKS Touring pedals from Amazon to replace the plastic ones that came with the bike. I switched out the OEM Kenda tires for some Kenda Kwest 700x35c tires. The OEM tires are identical to ones that came on my old hybrid, and they were flat magnets. The Kwests are still cheap tires, but they roll much faster and have far less tread than the OEM ones. They also seem to pick up less flat causing debris. I will have to save up for some Schwalbe Marathon Supreme tires, as they are not in the budget right now.
My main commuter bike up to this point has been my road bike, a Specialized Allez Steel Double:
The 3 speed isn't quite as fast as the road bike, but the 3 speed has a great ride. The bike came with a 44t chainring and a 22t rear cog, which makes the first gear really low. I ordered a 20t cog to put on it, as I've ridden a 3 speed with the 44/20t combo and liked its gear range.
