Minoura currently make two types of rollers and the MoZ is the lower-end model. With a roller width of 415mm (16in), they’re quite beginner friendly as you’ve got plenty of room for error if you swerve. Not that you really need it, as we found they give a stable ride.
Although the roller diameter of 80mm is small to provide extra resistance, this wasn’t enough to go really hard, but you can buy a magnetic resistance unit if you feel it’s not tough enough for your liking. We liked the three-way fold, as it makes them a little easier to store.
