The Best Spin Bikes Under $400 in 2021 (Reviews)

Finding the best spin bikes under $400 can be complicated. Most spin bikes are quite expensive, especially for home use.

Made from durable materials such as steel and featuring a heavy flywheel, these stationary bikes aren’t cheap to manufacture. But you can choose one of the spin bikes reviewed below to get in shape at home, on a budget.

The build quality of a spin bike makes most users choose these fitness machines over other similar exercise bikes.

Made with a durable frame and backed by a long warranty, these bikes have minimum electronics and are highly mechanical. This makes them stable and reliable for daily training.

What to look for when buying the best spin bikes under $400

Spin bikes come in all shapes and sizes, even when they cost up to $400. You might feel discouraged by the technical jargon used to describe their features, especially as a beginner. Here are a few things to consider when you’re after an inspired purchase.

Flywheel weight

The flywheel is the most important piece of a spin bike. Its weight is important. Lightweight flywheel supports easy pedalling, but they do not offer sufficient feedback with intensive cycling. Heavy flywheels require more force to get up to speed, but they can be similar to professional bikes with their feedback. Most cheap spin bikes are made with flywheels that weigh 30 and 45lbs.

Cage pedals

Cage pedals aren’t new to spin bikes. However, they aren’t offered on most spin bikes for home use. This is why most users should prioritize this feature as it improves both comfort and safety.

The comfort of the ride is improved when the foot moves together with the pedal. Cyclists shouldn’t lift the fit off the pedals during the workout.

Cage pedals also improve cycling safety. There are too many accidents where a foot or both feet slip off the pedals when the cyclists are standing up. To avoid such accidents, it’s best only to choose the best spin bikes with cage pedals. The good news is once the feet are fixed in the adjustable cage pedals, users can move along with the cycling session.

Digital monitors

A digital monitor is added to fitness machines to track and display workout progress. This is also the case with spin bikes, where digital monitors show multiple workout data. This includes the following parameters.


Studies show an average person can burn up to 300 calories cycling for 30 minutes. The 2021 best spin bikes estimate the calories cyclists burn during the workout. While the number is an estimation, it is still close enough so that you get a better understanding of your effort on your path to burn body fat.


The distance you cover on a spin bike is calculated based on the distance you would cover with a real bike out in the outdoors. It can be an indicator of performance where you know you need to cycle for several miles to reach a specific workout goal.


Time spent on the bike is also necessary. Most indoor cycling sessions at the gym last around an hour. This should also be the target workout duration for most home users as it offers the most calorie-burning benefits.

Heart rate

Not all spin bikes measure heart rate. But those that come with pulse sensors are ideal for people truly looking to improve health. A pulse sensor is typically added to the handlebars in common grip points. It measures your pulse, and you can interpret this to check your fitness progress. In time, your heart health should improve as you begin to build better cardiovascular endurance.
