I commuted for about 5 years, increasing my ‘loop’ as I got fitter, and was on 250km weekly commute. No special bike, an old Raleigh club, with 23mm Gatorskins( fun in the snow),with bottom bracket dynamo, then a Pearson Audax bike, with a hub dynamo. Loved every mile, I dids, never a chore. It was my warm up , and unwind from the job, I got work, got changed, strong coffee, and I was buzzing all day. If I ever drove in, I was asleep by lunchtime. Hub gears suck power , don’t they?
