It’s a heavy-duty exercise bike designed for spin workouts. It’s equipped with a magnetic resistance system, offers several workout programs, and excels in ergonomics.

The Diamondback Fitness 510Ic exercise bike features a high-tensile steel frame, protected by industrial-grade powder paint coating, highly resistant to corrosion. Plus, the belt, crank, and a part of the base frame are covered by durable ABS guards. It’s a one-piece, triangular frame, with precisi0n-welded joints for maximum sturdiness. It combines ovalized and rectangular tubes in its construction for improved aesthetics.
The bases of the frame feature leveling, rubber feet, to ensure maximum stability even during heavy spinning sessions. Also, the front base has silicone wheels, to ease the relocation and handling of the bike when fully assembled.
Overall, the bike isn’t extremely bulky. It actually has a floor footprint of 23″W x 42″L, and can fit pretty well even into a small room. It is however pretty heavy. At 104 lbs (~47 kg), you might require someone’s help if the bike requires to be carried up a set of stairs. Its weight is pretty important though, as it adds stability.
Seat and handlebars
The Diamondback Fitness 510Ic indoor cycle includes a saddle designed for superior comfort. It’s top features a thick layer of polyurethane for improved cushioning. It has two suspension springs at the rear so it can adapt better to the movement of the user during seated workouts. It also has a median cutout for improved breathability.
It’s important to mention that the saddle has a standard collar-based connection system. Therefore, if you will ever need to replace it, compatible options are widely available.
The bike’s seat is four-way adjustable (up, down, front, back). Its front-to-back slider is slightly inclined, in order to provide better positioning for taller users. The upright post offers multiple adjustment positions. So, this being said, the bike can accommodate users up to 6’5″ (196 cm) with no problem. It’s rated for a weight capacity of 300 lbs (136 kg), which applies to the seat as well.
The handlebar offers four-way adjustability just like the seat. Its upright post offers several adjustment positions while the front-to-back slider adds several inches of adjustment.
The handlebar features a multi-grip design. It integrates two, long side grips and two long aero bars. The lower grips are equipped with pulse sensors and the included console can monitor your heart rate if you hold on to them. Also, the whole handlebar assembly is covered by a layer of rubber foam material to provide a more comfortable and secure grip.
Drive and resistance
The Diamondback 510Ic features a servo motor-assisted magnetic tension system, similar up to a point to the resistance system of the NordicTrack Commercial Studio Cycle S15i. This means the resistance elements do not touch, so there’s no friction or wear-and-tear, while the pedaling motion is very smooth and quiet. The resistance is electric current generated; the bike offers 16 levels of resistance, adjustable exclusively via the bike’s console. You can use the bike without any resistance setting, or in other words, without using the console, and in this case, the resistance is pretty similar to riding a road bike on a straight road. On the highest resistance setting, however, pedaling is rather difficult simulating a steep climb.
The resistance system is enclosed within the drive system’s case. The large, wool-felt brake pad visible on the outside on top of the flywheel is just the bike’s emergency brake. So, do not mistake it for the bike’s main resistance system. This emergency brake is actually an important feature, though. The flywheel doesn’t automatically stop when you want to stop pedaling, especially in case you’re on a lower resistance setting. If your legs are strapped onto the pedals, they will follow with the pedaling motion for a few more spins. Evidently, in this case, the flywheel requires to be stopped.
This Diamondback exercise bike features an extremely solid, steel-made crank assembly. The crank arms are solid enough to support a 300 lbs (136 kg) user pedaling while standing up. In fact, it’s designed to support any spin workout. In other bikes, standing up while pedaling may feel awkward. The crank arms are finished with aluminum pedals, with toe-cages and straps. Pedals do not have cleats for spin shoes, but they do have standard threads. So, in case you want pedals with clips, you should easily find several models to fit.
Last but not least, this indoor exercise bike is belt-driven, featuring a 5PK1320mm, heavy-duty rubber belt. This means that the bike doesn’t require lubrication or any maintenance whatsoever when it comes to its drive system. It features a 31 lbs flywheel for consistent momentum. The flywheel is also perimeter-weighted, to provide a smooth motion, reducing the stairmaster feel, especially when pedaling on high resistance settings. In case you’re wondering, you can pedal in reverse but with the same resistance as you would pedal forward. Also, you cannot coast on this bike.
The console included with the Diamondback Fitness 510Ic indoor cycling bike offers quite an impressive range of features compared to the average exercise meter. To begin with, it has an LCD display with LED backlight for improved readability. The display is divided into several sub-sections, in order to show multiple workout metrics at once so you won’t have to use a scan mode to rotate them. It tracks time, speed, distance, RPM, watts, calories, and pulse. Speed and distance are shown in English units (MPH and miles); there is no setting for metric units.
The unit is not telemetric and does not have Bluetooth connectivity. Therefore, it cannot communicate with wireless HR chest belts or armbands. So, in order to benefit from a pulse reading, you will have to hold on to the sensors integrated into the handlebar.
The console does not have online connectivity and is not compatible with any fitness apps. However, it has its own program database to keep you motivated. It offers 14 workout programs. These are 1 Manual, 8 Preset, 1 User, and 4 Heart Rate programs. The manual program gives you the possibility to adjust the resistance as you like during your workout, as well as select goals for time, distance, calories, and pulse. The Preset workouts offer various workout settings; the top display shows the profiles of each program when selected. Needless to say, during a preset program, the bike will auto-adjust the resistance.
The user program allows you to create and save your own custom workout profile. And finally, the four Heart Rate programs include three preset ones for 55%, 70%, and 90% HRC, while the 4th gives you the possibility to select a custom HRC.
The console also makes available a Fitness Test or a Recovery function. This function measures the amount of time taken by your heart rate to return to normal after the workout, and based on the result, it will give you a fitness rating between F1 – excellent, and F6 – very poor.
Since the bike is motorized, the resistance can only be adjusted from the console, by using the Up/Down arrow keys. Also, the console does not require batteries. The bike comes with an adapter and the unit will draw power from the source you connect it to. The adapter connector is at the rear of the bike. And in case you’re wondering, its specs are 9V DC 500mA.
Assembly and Maintenance
The drive and resistance system of the bike come already assembled, closed within the plastic case, and attached to the frame. Therefore the assembly part only requires the attaching of the bikes bases, seat, and handlebars along with their posts, pedals, and the console. The whole task should take 30-45 min. Tools for assembly are supplied with the box, along with the manual.
For maintenance, the bike doesn’t require much. You basically have to keep the frame clean, wipe the sweat that might drop on it if it’s the case, re-tighten the bolts from time to time and that’s about it.
