The flywheel in an exercise bike is what creates resistance. You can choose the level of resistance to increase your workout intensity.

16 Levels
Resistance Type

The type of resistance shows what kind of flywheel is being used (if any), and its weight if the manufacturer provides it.


Type refers to the style of the ride: Recumbent bikes allow you to lay back, while Upright bikes are more like road bikes (lean forward).

Drive System

The bike's drive system is how your pedaling interacts with the rest of the bike (flywheel) to give you a good workout.

32. lb Flywheel

It's important to choose an exercise bike that will last, and the material of the frame determines how durable the bike is.

Anti-Flex Steel

The most important part for comfortability during your workout, the seat should be adjustable and have ample cushioning.


Pedals are the driving force for an exercise bike, and should be comfortable, adjustable, and easy to control without slipping.


Bike Programs allow you to complete a workout with changing speeds and inclines, without changing anything manually.

Heart Rate

Heart Rate programs allow you to track how many times your heart is beating per minute (bpm), and some control the workout for you.

Contact Sensor

Display refers to the screen you'll look at to monitor workouts. LED and LCD displays are similar to TV screens.

Max. Weight

Max. User Weight is the amount of weight, in pounds (lbs), that the bike can safely support, which can represent durability.

300 lbs

Accessory Tray

Diamondback 510IC Features

The Diamondback 510IC is a studio/spinning exercise bike which presents a different ride and feel compared to a recumbent exercise bike.

Spinning bikes are considered more aggressive with a chain drive system that offers moderate to difficult resistance for users preferring a more intense workout.

Spinning bikes are not considered as comfortable as recumbent bikes however the Diamondback 510IC has received praise for its sturdy frame and quiet operation from satisfied customers.

The Diamondback 510IC features a heavy duty 32 lb. flywheel which adds to the overall sturdiness of the exercise bike. The flywheel is one of the biggest we’ve seen on an exercise bike of any type.

The anti-flex steel frame is backed with a limited lifetime warranty and should remain durable under months or even years of aggressive use.

16 levels of resistance is more than adequate and is controlled via a computer system. LCD display provides workout essential data including calories burned, speed, RPMs and more.

The fore/aft seat and handlebars are both adjustable. Max user weight is 300 lbs. so the studio bike will accommodate most users.

The Diamondback 510IC does not offer many electronic features so you’ll need an external source for playing music or cooling off as the bike does not feature mp3 compatibility or built-in cooling fan.

The Diamondback 510IC is missing a few toys (no mp3 input, cooling fan) but overall it’s a good value for the price paid.

The studio/spinning design is a nice alternative to the more popular recumbent exercise bikes and thus fills a niche market.
