About Bike Trainers

A bike trainer is a device that clamps onto the rear wheel of a traditional bicycle and adds resistance, so you can practice riding in place.

Indoor bike trainers are a great way to stay in shape when you can't get out on the road or trail. Whether you're dreaming of nicer weather to ride outside, or just looking for ways to get fit at home, REI has a selection of bike trainers that will meet your needs.

Types of Bike Trainers

Bike trainers are categorized by the type of resistance they use and features they offer.

  • Wind: By powering a fan, these trainers use air to generate resistance. They're typically the least expensive but often the noisiest.
  • Magnetic: A magnetic flywheel provides resistance to your pedaling. They're relatively quiet, but some require you to stop to adjust the difficulty level.
  • Fluid: The trainer is filled with a liquid substance (often silicon) that increases difficulty the harder you pedal. They feel more like riding on the road but are often more expensive than wind or magnetic trainers.
  • Rollers: The most realistic type of trainer, your bike balances on a set of rolling cylinders. However, you must balance yourself and you might fall several times while learning how to use them.
  • Flywheel: These trainers offer more feedback and higher end features. They're great for those who really want to dial in their training regiment, but they're expensive and heavy.
  • Interactive trainers: These all-in-one trainers feature tons of data that will connect with your phone or computer. They often feature screens or apps that give a more immersive experience.

Choosing which bike trainer to buy will depend on how often you plan to use it, how close you want to mimic road riding and how much you're willing to spend.

You may want to outfit your trainer with accessories like a front tire block, sweat mat or a tire designed for training. Also check for compatibility with devices via ANT or Bluetooth, and add-ons like cadence monitors or fans.
