Angular Velocity - More!!!

Hi guys!
THis one seems really simple, but i just cant seem to find an equation to help. I know the front tyre of a bike is clamped and the back is placed on a roller and the pedals are turned such that if the bike had been free it would have been going at 8.3 ms^-1. The outside diameter of each tyre is 0.66m

I need to find that angular velocity of the rear wheel somehow! I know v=rw, but cant seem to work it out!

Thanks all physics boffs.

why isnt it just ω=vr\omega = \frac{v}{r}

= 8.3 / 0.33 = 25.2 rad/s ?

is that wrong?
No, that's right! Often the questions are a lot simpler than they seem.
