The Diamondback 510sr Recumbent Bike is designed to suit a variety of different users. No matter what your fitness level or goals may be, you’ll grow to love this machine. It’s comfortable, ergonomically designed, and can be customized to your body type and personal preferences.

Our Dislikes

While Diamondback 510sr reviews remain largely positive, there are a couple of things that users should take into consideration.

  • Although the bike comes with a set of instructions, users may find setup to be rather time-consuming. If you’re setting up yourself, you may need to dedicate up to 2-3 hours to the process. However, if you have another person to help you, the two of you will find setting up much easier and faster when working as a team rather than on your own.

  • Another challenge that you may encounter while using this bike is adjusting the seat. Although the seat may be adjusted to suit your height, doing so may require a bit of strength. There’s a small knob that must be unscrewed, and it may be quite tight after previous adjustments. This tight fit, however, will ensure that the Diamondback 510sr remains strong and sturdy throughout operation. This machine does its duties and will last you a long time.

Our Verdict

Investing in a recumbent bike may be a great way to get the entire family to work out. For those who are easing into exercising or are suffering from mobility issues, the Diamondback 510sr will give you the right support and positioning to get a workout that is low-impact and easy on joints. For fitness fanatics who are looking to push beyond their limits, the machine has 16 levels of resistance and 20 different pre-set programs that are sure to keep you satisfied.

The additional features, including the LCD display that allows you to monitor your progress, cooling fans, and speaker system will help make your workout as enjoyable as possible. The magnetic resistance will ensure smooth and quiet motion while pedaling.

While the setup may be time-consuming and adjusting the seat will require a bit of strength and effort, the Diamondback 510sr will be well worth your money. It’s strong and sturdy and will continue to operate well after prolonged use, lasting you a long time. Also check out Best Recumbent Exercise Bike Reviews 2018.
