I have returned to Internally geared hubs for my daily ride,
big advantage in being able to select a gear ratio change when stopped , and moving slowly.
A chain guard will separate the dirt on the chain and your trousers..
New designs add to the range of ratios from traditional 3, and 5 to 7 and 8 speed ..
most recent purchase for me was a folding bike , It sits in a corner of the room Folded up.
taking up little space .. where the big wheel non folders are taking up a significant amount.
