I have started cycling more and am currently tracking my speed with my phone. The only stats I’m really interested in are speed and heart rate, so I’m considering getting a heart rate band and getting a phone holder for my bike so I can see my speed and heart rate while cycling. Is this a good idea or would a bike computer be a much better option? The expensive ones are just way to expensive and the cheap ones seems like kind of the same as using a phone
