The 910SR is one of the recumbent exercise bike models released by DiamondBack Fitness in 2014. Although it’s a rather old exercise bike compared to other models, it’s still available as it is a high-quality trainer and so far it has benefited from a consistently positive feedback from users all over the U.S.

The Diamondback Fitness 910SR it shares many similarities with the 510SR model, but has a sturdier frame, offers more levels of resistance and more workout programs. Even though it is a heavy-duty exercise bike, it’s not advertised or sold as a commercial model and only comes with a residential warranty.

Frame construction

The Diamondback Fitness 910SR has a frame with a step-through design which results in an easy access to the seat and pedals; this can be an important feature for users with disabilities. As we’ve mentioned above, it has a heavy-duty construction similar to the gym-grade bikes. Its frame is made of steel tubing but does also integrate several ABS material parts, such as the covers of the flywheel, the covers of the rear seat frame, and several other small covers.

The bike’s frame is considerably heavy. When fully assembled, it weighs approx. 130 lbs (58.9 kg). This weight is reflected in its overall stability. You can be sure that the bike won’t wobble or move when you exercise. Plus, both its bases are equipped with adjustable stabilizers. They have large rubber caps which improve the unit’s grip onto the floor.

Despite the bike’s weight, its transport isn’t too difficult once it is assembled. Its front base integrates a large roller which facilitates its relocation. Therefore, by lifting the trainer by its rear base and using the transport wheel, you won’t need to handle more than 45 lbs.

Like most recumbent bikes within this feature and price range, the Diamondback 910SR is a fairly large unit. With the frame fully assembled, its footprint is 63″L x 23″W (163 x 58 cm). However, it is recommended to allow at least two feet of clearance all around it for safe operation and ease of access. The unit’s highest point is approx. 50″ (127 cm) above floor level; it’s given by the top part of the console.

The bike’s frame is double-coated with a rust-resistant and abrasion-resistant paint finish. The color used is gray, this being the only version available for this exercise bike.

Seat & handlebars

The Diamondback 910SR features an adjustable seat. It is attached to a metallic rail which has several adjustment positions. Its front to back adjustment span can accommodate users between 5’0″ and 6’5″ (153 – 196 cm). Its adjustment is done with ease via the lever on the right side.

The seat has a durable vinyl upholstery. Its surface is contoured and it integrates a thick layer of foam padding for optimal comfort. It is 16″ (40 cm) at its widest point and 11″ (28 cm) deep. It’s also durable enough to support users up to 325 lbs (147.4 kg).

The backrest is also adjustable; its backbone has 6 adjustment positions. Therefore, you can place it at the most comfortable height for you. The backrest features a mesh structure which not only that adapts well to the shape of your back, it also promotes a maximum airflow reducing overheating.

The bike is equipped with two sets of handlebars, one attached to the seat assembly and one attached to the console mast. The seat’s handlebars integrate EKG sensors; by holding them tight as you pedal, the console can monitor your heart rate. Both sets of handlebars have a layer of rubber foam material in order to provide a comfortable and secure grip.

Resistance & drive

The Diamondback 910SR features a motorized magnetic resistance system. Its main elements are a small internal servo motor and a magnetic brake device. The resistance can only be adjusted from the console and the bike requires being connected to a power source via a power adapter (which is included). By selecting a certain resistance level from the console, the motor will move the brake mechanism closer or farther from the flywheel, this way increasing or decreasing the intensity of the internal magnetic field, and respectively adjusting the resistance that the pedals meet.

The bike’s resistance system offers 32 distinct tension levels. The first levels generate little resistance; basically, the only resistance that you’ll get for the first level is the flywheel’s weight alone. Conversely, the 32nd level of resistance simulates a steep climb, giving you the possibility to train on a more intense level. Also, it’s important to mention here that certain preset programs auto-adjust the bike’s resistance.

The bike is equipped with a 32 lbs (14.5 kg) flywheel, which is fairly heavy for a recumbent bike. It generates quite a bit of inertia and it’s bi-directional. In other words, you can pedal in reverse if you want, and the console will continue to measure your workout stats; however, the bike doesn’t allow you to coast.

Like most other magnetic exercise bikes, the 910SR features a belt drive system. Therefore, the pedaling motion is extremely smooth and almost silent. It also doesn’t require lubrication as a chain drive.

The crankset is an extremely durable 3-piece part. It features heavy-duty steel arms with a chrome finish. It could probably withstand the user in a standing up pedaling routine, but this type of exercise is not recommended; the bike is meant for seated workouts only.

The pedals are made of a durable ABS material. They’re weighted so they always turn face-up when your feet aren’t on them. They are equipped with adjustable straps so you can perfectly secure your feet on them. They don’t have SPD clips but they do have standard threads of 9/16 so you can easily find replacements for them.


Although the bike’s console offers a pretty impressive range of workout programs, it doesn’t connect online. In other words, it’s not compatible with iFit or other online applications. It features a large LCD display with blue LED backlight and large digits for enhanced readability. It’s divided into several sections so you can see most of the workout stats at once. The top four panels show the level of resistance, total time, segment time, and watts, while the bottom section scrolls between distance, calories, RPM, and speed. The middle section indicates your heart rate and the program matrix.

Distance and speed can be set up in both standard and metric units. The unit can measure your heart rate through the sensors integrated into the seat handlebars. However, it’s also telemetric; this means it is compatible with various Polar HR chest strap transmitters. An HR strap is not included, though.

The console unit offers 32 workout programs in total. There are 6 Interval programs, 6 Hill Climb programs, 6 Strength programs, 3 Fat Burn programs, 5 Random programs, 5K & 10K programs. Each program category has its own key on the left of the console. Along with these, there is also a Fitness Test program and a set of Heart Rate programs. The Fitness Test evaluates your fitness level at the end of your workout based on your pulse rate. The Heart Rate programs depend on a selected HR interval and adjust the unit’s resistance to allow you to remain within that selected HR interval. Of course, there is also the Manual mode which gives you the possibility to adjust the resistance as you pedal, without the need to preset anything.

The console has two user profiles. Each user can input their personal data such as age and weight, as well as the workout time and resistance level.

Along with the workout programs and all the other related fitness features, the console also offers several amenities. Among them, we can count a stereo sound system, a cooling fan, a USB charging port, a docking bay for your tablet, and a magazine or book holder.

The sound system consists of two small speakers placed on the two bottom corners of the console. Its audio jack input is compatible with most MP3 players, tablets or smartphones. However, the unit doesn’t have volume controls so you will have to adjust the volume from your device.

The cooling fan is also placed at the bottom of the unit, between the two speakers. It has an adjustable fan louver which allows you to adjust the angle of the airflow. It has three settings, low, high and smart. The smart mode gradually intensifies the airflow depending on how fast you pedal.

The top docking bay for a tablet or phone has the two ports, audio and USB. The USB port is only for charging your phone or tablet as you exercise; it doesn’t allow you to copy your workout data in order to transfer it to an online fitness app account.

The bottom section of the console is equipped with a magazine or book holder. It can be folded/unfolded up. And finally, the whole console assembly can be tilted by several degrees in order to provide the best angle depending on your height.

Assembly & Maintenance

The base frame of the Diamondback Fitness 910SR comes pre-assembled. In other words, the drive and resistance elements are already attached to the frame. The seat’s adjustment rail is also in its place, so you will only have to attach the bike’s two base stabilizers, the console mast, the console, the seat, the handlebars and the pedals. This may take more than an hour. However, the manual offers very clear assembly instructions and schematics, while all the tools necessary for the assembly are included.

Maintenance doesn’t require much. All you have to do is wipe the perspiration that may fall on the bike with a piece of cloth, keep liquids away from the console, and periodically inspect the bike for loose bolts and parts.
