Yes, I'm afraid that's what I thought too, but it looks like Bosch take a walled-garden approach. Their app will give me all the data from the bike, but will not connect to a heart rate monitor, which is flat-out stupid in my opinion. I really hate it when manufacturers en****tify their products to force you to use their solutions, and then do not offer a workable solution. Ho-hum, first-world problems I guess.
