You only weigh 5 stone Bob!
Even at 16, I was about 6ft 2" and a good 12 stone. Tent and one week kit bag was like carrying a passenger.
Up hill the 2nd gear on a 3 gear was just OK. I seem to remember my friend Tony having more trouble with the 2 gear.
You are going to tell me that the ratios of 2nd gear are the same as 1st gear on the VS 2 speed???
I know that I got up Maldon hill at high revs in 2nd but Tony was in first gear and couldn't keep up. He was really screaming.
