Zwift TT bike

At what point can you use the Zwift TT bike?

You can use it whenever you wish. When stopped click on the ‘Menu’ button in the bottom left and then ‘Customize’. You should be able to choose the Zwift TT bike from there.

The TT bikes are a little heavier and don’t allow for power-ups, nor drafting, however you’ll get a significant aero advantage.

I was wondering why I never got a power-up… why aren’t TT bikes allowed to get them?
