Here are some possibilities: Won the lottery. Decided he hates bikes. Scared of petrol. Got a pet dog, turns out he's allergic to dogs, went to allergy clinic, met this lovely lady called Doris who is also allergic to German shorthaired pointers, got married, moved to Isreal. Now plays FIFA 2017 as a professional. Realized he was meant to be born a woman and is now called Sharon and sells Apriliias instead as they're girls' bikes. Scared of dragons so had to move away from Wales. Caught Ebola, recovering well. Sasquatch got him. Stole a supperleggera and rode off into the rain.
