Best Indoor Bike Trainers Review

The best indoor bike trainers are an invaluable tool for serious cyclists going nowhere fast. But all jokes aside, for those unfamiliar, the indoor bike trainer is a piece of equipment which allows cyclists to ride fast while the bicycle remains stationary. Bike trainers, whether used for warming up before a race, or taken indoors when riding conditions are poor, this equipment is a must.

The explosion of all things smart in exercise equipment has come to indoor bike trainers as well, bringing along with it numerous training apps and online communities. The basic types of bike trainers include the direct drive trainer, which attaches to the rear dropouts and substitutes for the wheel using a cassette, while providing a direct connection to the resistance piece. Friction trainers utilize a small roller which goes up against the rear wheel and incorporates either magnetic or fluid resistance. Rollers are the simplest of the trainers and essentially perch the bike on top of three rollers. A smart trainer differs from the others in that it can communicate wirelessly with an app, device, or virtual world like Zwift.

With virtual training platforms like TrainerRoad and Zwift being such a prominent phenomenon, compatibility with the app of the user’s choice is probably as important as the other dimensions. Zwift is undoubtedly among the leaders of bike trainer fans, but for those seeking a machine just for race-day warm-ups, units such as the Feedback Sports Omnium Over-Drive Portable Trainer are out there. Not among our top five selections due to its lack of virtual connections, it’s among the market leaders for those seeking just that.

Qualitative issues to consider along with price include the resistance type, stability offered, and compatibility with online apps. Check below our review of the five best indoor bike trainers on the market today and get to burning tread.

Why Indoor Bike Trainers?

For cycling enthusiasts, the feel of their own ride can be quite addictive. Competitive riders need to keep their programming regular, and yet, Mother Nature can be quite uncooperative. The best bike trainers allow riders to train year-round in any climate simply by hooking their bicycle up to one indoors. And, instead of the relatively limited usage of a true indoor bike, these can help one get the best bang for their bicycling buck. Racers are often seen using them to warm up before the start.

The biggest questions for consumers often center around price, but keep in mind the growth in technology available by way of these units today. As one check the prices, which range between hundreds and thousands of dollars, they’ll also see a big difference in features. Just like bicycles themselves, shoppers for trainers can get as intense as they’d like here in this field.
