Reading your post below, a thought 🤔.
Brought on by the fact our car, neither a jag, citroen or mustang (ok, it is a japanese thingy but forget what) has lots of warning lights flashing, quite festive for the time of year, but the garage cannot look at them for 3 weeks.

When will a cycle manufacturer start installing warning lights for malfunctioning parts? Imagine the fun of flashing handlebar lights and the tales to tell in the pub after a ride.
