Best Bike Trainers For 2021 – New Models With Resistance Roller!

Bike trainer help avid cyclists train for races, get some exercise in the comfort of their own homes during inclement weather and make it possible to get a great workout without leaving the house. Bike trainer should have sturdy construction, great warranties for factory workmanship and a great standing within the industry.

Best Bike Trainers

Bike trainers work by elevating the rear wheel of your bike while maintaining its balance. This allows the rear wheel to spin freely when you pedal, but the front wheel remains stationary. You can shift gears, pedal as fast as you want and get a good workout without leaving the house.

Add some enjoyment to this routine by purchasing special videos that take you on scenic tours along a bike path. That way, you can shift gears going up or down hill by following any directions given within the video. Before you know it, you have a 30-minute workout under your belt and all you did was ride your bike in your house for a little bit.

Things to Consider Before Buying Bike Trainer

You have several factors to consider when you purchase the best bike trainer on the market today. These things should all lend to how the trainer works with your bicycle at home.

1. Construction

Obviously, you want a bike trainer made of sturdy materials so it can stand up to regular usage. Aluminum bike trainers are lighter in weight than steel varieties while maintaining structural integrity. However, both aluminum and steel alloys are the best materials for these devices. Metal should be sturdy, free of sharp edges and it should anchor the rear axle fairly well.

A bike trainer isn’t lightweight. These devices weigh around 20 pounds, so expect to get a sturdy item when you receive your shipment from Amazon.

2. Resistance Roller

The resistance roller should spin freely as the rear wheel moves. The roller is the part of the bike trainer that contacts the rear wheel of your bicycle. The roller should make you feel as if you are pedaling your bicycle normally at first. A good bike trainer allow you to adjust the tension of the resistance roller on the fly.

Some bike trainers contain resistance roller controls that you operate from the handlebars. This makes it very easy to simulate terrain, although that’s why you have gear shifting on your bike. Resistance rollers should produce normal wear on your tires rather than creating extra wear.

3. Three Varieties

There are three main varieties of bike trainers on the market. The least expensive of these is a wind trainer, which uses the roller to turn fan blades in order to create wind resistance. Wind trainers are loud due to the moving fan blades. Magnetic trainers, or mag trainers, use magnets to operate an eddy current brake. This brake controls the resistance roller precisely.

These trainers may have handlebar controls, and they are in the middle range in terms of price. Fluid trainers are the most expensive and quietest of the bike trainers. Liquid-filled chambers create resistance in the rollers.

4. Steel Skewers

Most new bike trainers come with steel skewers. Steel skewers let your bike fit more securely in the clamp. This reduces possible accidents or injuries in case your bike slips off of the trainer. Steel skewers also help lessen the forces that may make the bike trainer wear out faster.

You may have to change out the skewer on your rear axle at first, but once you get the hang of it there shouldn’t be many problems.

5. Easy Assembly

Bike trainers are need to assemble easily. If possible, look over the instruction manual online before ordering a bike trainer so you can see how it fits together. Most bike trainers come with instructions that are easy to follow. The best ones have paper manuals and how-to videos you can find online.

Even though bike trainers are somewhat heavy, once you assemble one they basically fit in a compact space. Set your bike trainer in the corner of a room or within your garage. If you have a little bit of space, the assembled bike trainer fits in it.

Now that you know what to look for in a bike trainer, let’s get into reviews of the five best bike trainers on the market today.
