What do you want from your turbo trainer? If you are planning on using it to warm up before a time trail event, you’re going to need it to be portable. It’s important to consider how space efficient the turbo trainer is, and whether it can fold up flat. The Minoura B60 Remote Trainer is a good entry-level product that folds up nicely.
But most people will want their trainer to sit in the garage or spare room, and therefore sturdiness is preferable to portability. You want the frame of the trainer, usually made of steel, to be as stable as possible with a wide frame stance. After all, you’re going to be doing some high-intensity stints and you’ll need your trainer to be able to deal with your weight and breath-taking power!
