A coworker commented that I have an incredibly heavy bicycle, probably over 30 lbs. It's a bit like a tank, with a steel frame, an IGH, drum brakes, fenders, rack, kickstand, etc. It's not unpleasant to ride, I lowered the gearing and it's a nice ride overall. But that conversation got me wondering whether or not my bicycle is absurdly heavy (and maybe if I should go lighter somewhere down the road) and how much of an impact does the weight of your bike have on your commute. Thoughts?
