The Good

20 workout programs and 16 resistance levels

The Diamondback Fitness 510Sr Recumbent Bike comes preloaded with a terrific selection of automated workout routines designed to simulate different types of cycling conditions and help you diversify your workouts. Preloaded routines include strength programs, interval programs, hill climb programs, and two so-called fat burn programs. There are also several programs designed to vary the resistance level based on changes in your heart rate, which the 510Sr bike monitors through contact sensors in the handlebars. You’re also free to control the pedal resistance using push-button controls on the console. With 16 levels of resistance available, it’s easy to fine-tune the difficulty to get the most out of your workout. Unlike some other exercise bikes on the market, the Diamondback Fitness 510Sr’s frictionless eddy current braking system responds immediately to resistance level changes without any noticeable lag or disengagement between levels.

Large, easy-to-read display

While a lot of recumbent bikes come with small, uninspiring digital displays, the Diamondback Fitness 510Sr is outfitted with a large display console holding a bright, back-lit LCD screen. As you work through your exercise routine, the display tracks a variety of vital statistics in real time, including your heart rate, your speed and distance traveled, your calorie count, and your elapsed exercise time. When you grip the contact sensors in the handlebars, you also get a real-time readout of your heart rate. What’s more, the display console also features integrated stereo speakers, an audio jack, and a media bay for your personal music device in addition to an adjustable fan.

Superb warranty

The Diamondback Fitness 510Sr also delivers a very solid warranty that rates among the best in the consumer exercise bike market. As the owner of a new Diamondback Fitness 510Sr bike, you get a lifetime warranty on both the frame and the frictionless eddy current braking system, a three-year warranty on electronic components and mechanical parts, and a one-year warranty on labor associated with warranty work. Wear items, such as seat cushions and pedal straps, are covered for 90 days. With this kind of thorough coverage on the frame and mechanical parts, you can be confident that your investment will be a part of your fitness routine for years to come.

Hassle-free shipping option

The Diamondback Fitness 510Sr Recumbent Bike weighs in at about 125 pounds. While the bike is not terribly difficult to assemble, requiring as many as two or three hours at the very most, the weight may be too much for some buyers to handle safely. If you’re worried about getting your new bike assembled properly and ready to use, Diamondback Fitness offers a special shipping plan just for you, known as the White Glove Delivery Service. Order this service to have your bike delivered to your home, placed in the room of your choice, and assembled and tested by professional movers. While the White Glove service is a little spendy at about $180, few other exercise bike companies offer such an option at all.

Adjustable non-stick seatback

Aside from the major features that come with this terrific exercise bike, many actual users point out how comfortable the adjustable seat is. In addition to a generously cushioned seat bottom, the seatback is made from comfortable, non-stick mesh material. While vinyl seatbacks promote sweaty, sticky conditions, the Diamondback Fitness 510Sr’s mesh seatback enables airflow to reach your back, helping to keep you cool. The seatback also features an up-down adjustment capability so people of all sizes can match the seatback to their height, a benefit only few exercise bike seats offer.

Step-through design for easy mounting

Recumbent bikes are often recommended by doctors and physical therapists to help people with injuries or reduced mobility issues to get low-impact exercise. The Diamondback Fitness 510Sr bike is built without a center step-over bar common to many recumbent bikes, making it a good option for people with reduced mobility. With a step-through design, you don’t have to lift your legs or make any awkward movements to get on the bike. Simply step through the open saddle, sit down, and get ready to pedal.

The Bad

Lacks workout journal software

The only major omission in the Diamondback Fitness 510Sr Recumbent Bike’s feature list is the capability to track workout statistics from day to day. While you get to see a handful of interesting real-time statistics for each individual workout — including speed and distance traveled, calories burned, and heart rate, among others — you have to manually log them in a notebook if you want track your performance over time. Some exercise bikes on the market, such as the Schwinn® 250 Recumbent Bike, for example, include on-board software designed to track your workouts automatically. While the Diamondback Fitness 510Sr is a fantastic bike, adding this kind of capability would complete its feature list and make it a true home-run choice.
