Back when the app was ~$19/month it allowed you to use multiple users ( unlimited I believe). When they reduced the price to $12.99/month it became limited to one user at a time. From what I've heard, they give this out as a complimentary thing while you're waiting for your bike and it only works with one profile. Once you get your bike and are paying $39/month you'll then be able to add multiple profiles for everyone in your household.
