Speed please

Hello all. I’ve literally just connected my new zwift hub one and everything seems ok expect that even when I pedal like crazy, I only seem to be going at a top speed of 10-12kph with literally everyone overtaking me. Any ideas as to what I need to do apart getting fit?

It sounds like you don’t have a Click or Play controller paired, OR if you do have it paired, the virtual shifting setting is not enabled.
