Add different bikes/riding styles to the availability screen

For example:

My main bike is my road bike, which I ride outdoors. But I also do a ride on my mtb every Sunday and a indoor ride every Tuesday or Wednesday. Not all workouts are great for every riding style. It isn’t great to do long workouts indoors and other way around some workouts do work great on a mtb. It would be nice to have a option to tell Join which types of bikes I own and select which bikes I would like to use for each day during the upcoming week (in the availability screen).
