A couple of years ago, in my spare time I trained as a Bikeability instructor, and also did various Cytech bike mechanic courses due to getting a bit disillusioned after 35 years in the financial services industry. Helping millionaires keep their millions is a bit soul destroying.......
Anyway, I've now formed a CIC to recycle unwanted bikes, run training courses and other more useful things. One week in so far and 14 bikes renovated. Definitely more rewarding from a human perspective.
