Mike Nelsonwrote a review of CycleOps The Silencer Direct Drive Mag Trainer on December 24, 2014
Familiarity: I've used it several times
This seems to be the main question about this unit, and with good reason! It is called the Silencer after all. So I'll get right to the point. It isn't as silent as owl wings or falling leaves, but it is quitter than any other indoor trainer I have used. It is quite enough that I can ride it while the kids watch cartoons in the same room without having to crank the volume on the TV. It is quiet enough that I can ride it while other people sleep in the house. It is quieter than the dishwasher. I attribute this to the magnetic resistance unit, and to the direct drive. A lot of the noise on tire-driven units comes from the howl of the tire as is spins against the trainer.
There are other things to like about the silencer as well. This is a big, heavy piece of equipment, with most of the mass in a wide and solid base. It also does not require a riser block. Tthe front tire sits on the floor. No acrobatics are required to get on and off. Sitting on a bike in the silencer feels much more stable than other trainers, practically comparable to a stationary bike. Other trainers I've used have a bit of a tippy feel. The flipside of all this stability is portability of course. This probably is not the ideal trainer to take to the races for warming up.
