Diamondback Fitness 510ic console

Take the guess work out of your workout and say goodbye to the days of wondering where you stand in your fitness journey. The Diamondback 510ic has a high contrast LCD screen that allows you to track everything you need to know about your workout. You’ll be able to review your ride profile, heart rate, cadence, speed, distance traveled and elapsed time.

A bit part of your health is related to your heart rate so you can ride easy knowing that your ticker will be taken care of. Included in the design of the Diamondback 510ic exercise bike are contact heart rate sensors that let you track your heart as you cycle your way through the 4 heart rate controlled programs. 

Build quality

If a well constructed exercise bike is what you’re after, look no further than the Diamondback 510ic. It has a high-tensile steel frame that is coated using an industrial-grade powder paint to keep it safe from corrosion. The Diamondback 510ic indoor cycle also features high-quality multi-position handlebars that are covered by a soft foam covering for your comfort and convenience.

Everything about the Diamondback 510ic indoor cycle bike has been built with your ease in mind from its built-in bottle holder to its magnetic resistance. Thanks to its superior usage of materials, cleaning and maintaining the 510ic is a simple case of wiping it down with a soapy solution before drying it with a clean towel. 

Flywheel weight

The Diamondback 510ic’s flywheel weighs a whopping 32lbs to help create the momentum and feelings associated with riding out on the road. This is a really great feature as it is able to provide a more fluid cycling motion as opposed to a jerky unstable one which could even lead to injury.

Ease of assembly

If you’re worried about spending hours upon hours assembling your new fitness bike, don’t be. The 510ic comes with a comprehensive instruction guide found in the Diamondback owner’s manual that details the exact step by step process that you need to follow. So read carefully and follow the instructions & you’ll be in for a smooth assembly.

Here’s an overview of the assembly process:

  1. Unpack it and remove the tubing. You can throw this tubing away as it is only used to prevent damage from occurring during the delivery process.
  2. Go through the contents of the box and make sure that all parts are accounted for.
    Align the front stabilizer to the front frame’s receiver and loosely install it. Once you’ve installed your bolts and washers you must tighten the overall installation. Follow this same process to install the rear stabilizer too.
  3. Install saddle onto seat post and tighten it. You can do this using the included wrench.
  4. Install the left pedal by threading it by hand onto the left crank. Be sure to use a counterclockwise rotation and then tighten it. Repeat this process to install the right pedal but rotate it clockwise instead of counterclockwise.
  5. Install handlebars. This is simple as all you need to do is slide the bracket up under the handlebar mast before feeding the heart rate console wire through it. Position the handlebars in whichever of the three possible positions is most preferable to you.
  6. Now move onto your wiring (again, the step by step instructions are included) so if you aren’t comfortable with wiring you’ll need to make sure that someone who is can help you with this step.
  7. Install water bottle holder using the two bottle holder assembly screws.
  8. Do your endcap fixing. 

Once you’ve followed the outlined steps, you’ll need to position the unit exactly how you’d like it and level it by rotating its four leveling feet found in the stabilizer bars. Next, make your final up and down handlebar adjustments & fore aft adjustments on the seat.

Finally, plug it in and let it charge before taking it for a spin! 

Weight limit

Don’t worry about the Diamondback Fitness 510ic being able to support your weight because it has a 300 lbs maximum weight capacity. This is enough to accommodate most people and their cycling gear. In addition to the weight requirements, the 510ic has been specifically designed with those who measure between 5’3” and 6’5” in mind.

Number of Workout Programs / Levels of Resistance

Diamondback Fitness 510ic workouts

The 510ic boasts a total of 12 workout programs. 8 preset and 4 heart rate controlled resistance levels put you in total control. You can also take advantage of manual as well as custom programs. In terms of resistance, you have 16 resistance levels to workout as intensely or lightly as you’d like.


With the 510ic, you can adjust its seat height, fore aft positioning as well as the height and fore aft positioning of the soft foam-covered handlebars. While it IS easy to adjust and can be easily adjusted to cater to those who have heights of between 5’2” to 6’5”, it’s not adjustable enough to cater to multiple users. If you’re looking for an indoor cycle machine with high levels of adjustability, you’d be well served by looking towards the Diamondback Fitness 910ic instead.

On top of its physical adjustment capabilities the load level can be adjusted in all of its modes being manual, beginner, advance sporty and cardio. In addition to these modes, its watt level can also be adjusted in watt mode. 

Dimensions and Amount of Space Needed for It in Your Home

The 510ic arrives in a 42” L x 15” W x 35” H package, but you’ll need a little more space than that to set this bad boy up for success. Its assembled dimensions are 45” L x 15” W x 35” H so you’ll need to keep it in a space big enough to accommodate its size.

This space also needs to be well ventilated, indoors, feature a solid surface and big enough to meet the bike’s minimum clearance requirements of 24” at its front & sides as well as 12” at its rear. Also bear in mind that the bike does have a steel frame and weighs 104 lbs so you may want to avoid putting it in an area that requires you to carry it up stairs. 


If you’re worried that the 510ic won’t be able to withstand rigorous use, place those concerns aside and find comfort in its limited lifetime warranty. This limit lifetime warranty applies to its brakes and its frame including any welding, workmanship or material defects. Note that the machine has an expected lifespan of 5 years although many report it lasting much longer than that.

In addition, its wear items have a 90 days warranty, its labor falls under a 1 year warranty and its parts & electronic components are covered by a warranty of 3 years. You’ll need to provide proof of purchase in order to be eligible for immediate coverage otherwise the coverage period is only effective from the date of 6 months after its manufacture date. 

What Others are Saying

All in all, the Diamondback 510ic indoor cycle machine has a reputation for being a great piece of exercise equipment produced by a great company. Its customer reviews often indicate that the vast majority of customers are thrilled with the machine and praise it for its user-friendliness, inexpensive price & solid build.

In terms of complaints, there aren’t many. A few users are disappointed by its lack of internet connectivity and a handful of people have stated that the standard seat isn’t as comfortable as it could be. 

Who is the Diamondback 510ic Best For?

The Diamondback 510ic is best for a single user as it doesn’t have the highest level of adjustability unlike other Diamondback units like the 910ic. In addition, because of its 300 lbs weight capacity and height requirements, only people who meet the user requirements should use it. 

Other than those restrictions, this exercise bike is suitable for anyone and is a great option for those who are interested in weight loss, everyday strength training & cardiovascular workout routines.
