The Dutchie I was given had way too high gears for North Britain, let alone Kirk Brae.
Went to the Bike Station, got me a pair of MTB cranks and a 22-tooth chainring. Cut the gear stack in half. (I just invented 'gear stack'. Cool huh?)
Tested it on a run to the shops and over the football pitches. Seems dandy. Young ladies smiling/laughing at the old boy on the granny bike.
Chaincase don't fit no more but them's the brakes.
