Hi Cbad & burton, thanks for having me.
I ride a Learsport (local company around here):

I ride a Norco mountain bike (circa 2000) when going the short way. It's got knobby tires, and it's too small for me but for some reason I'm still enjoying it.
I have a dream about getting a commuter bike that's big enough for me (6'6 and 115kgs) and has panniers, gear hubs, dynamo, the whole works. But they're pretty hard to find down here.
