Being Attitude for Gains (gym thread)

Anyone ever used one of these things?

Example 1 | Example 2

You put it on the rear tire of your bike to turn your bike into a stationary one, so you can exercise at home.

I like the idea of getting one of these over getting an entire separate exercise bike.

I guess the things I’m worried about are:

  1. How loud are these things?

  2. Do the resistance levels go high enough to actually give a decent workout?
