~5 minutes cycling vs ~5 minutes on the motorcycle, give or take - a bit longer on the motorbike to get it out of the garage and moto parking is on the far side of the building, so parked-to-office takes longer. Or 10 minutes walking. Car parking would be similar to moto parking, but I don't have a car. In either case, spots are all gone unless you show up early.

Not sure the math works out when the commute distance is under one mile, but if your commute is that short you don't need a ratio to know that biking makes sense!
