There will always be a debate between stationary bicycle trainers and rollers, one of which being their respective effectiveness. Many claim stationary trainers aren’t so because they do not simulate actual road conditions where one has to maintain the bike’s balance; the trainer basically keeps the bike in a permanent state of stability.
This debate is probably for another article, but for those unfamiliar with bike trainers, they are indoor cycling simulators that you would hook up your own bike with. Trainers are especially useful for anyone seeking to clock additional mileage, but is unable to do so due to circumstances like time constraints or wet weather. With indoor trainers, you’re able to schedule a ride at any time, cycling as long as you need to.
