I’ve got a bike bag, so to be safe, I could buy an old second hand bike from the bike guy at my local market.
Pay the airline an extra £90 for the bike bag both ways.
Give the old bike to charity in Toronto, by a new bike, ride it round the single track around Don Valley in Toronto for a week (going to be there for 3 weeks).
Bring it home and still save a couple of hundred quid, jobs a good’un, I hope!!
