Features:

12 Programs

The 5101c is a rarity in terms of spin bikes because it provides you with 12-built in workout programs. This allows you to use it to achieve every type of workout you want, from hills to mountains and all sorts of terrain in between. You also get four heart rate programs.

Quiet Operation

The Diamondback 5101c makes use of magnetic drives to power the bike. One result of this is that you get a whisper-quiet operation. That’s great if you’re exercising in your lounge room while others are watching TV.

Heavy Duty Frame

The 5101c is made from solid steel. This makes it rugged enough to handle a 300-pound maximum user weight. It is durable enough to last for many years. The bike weighs 126 pounds and will not wobble from side to side, even when you’re spinning at full intensity.

16 Resistance Levels

You get 16 levels of smooth, adjustable resistance on the 5101c. You don’t get any of the jerkiness that is common with lesser models so that the transition between resistance levels is very natural. Once you get to level eight, the resistance starts to get quite challenging, so there is plenty of range here to challenge even the fittest person.

Customization

The 5101c provides full rider customization by way of handlebar and seat adjustability. Both can be adjusted fore and aft as well up and down. In fact, this bike can be used by people with heights of between 5’2” and 6’5”.

Pedals

A secure foothold is important when you’re exercising on a spin bike. The 5101c has you covered with tie clips to ensure that feet are kept solidly in place. However, these pedals will not take spinning shoes or cleats.

Storage

The 5101c can be easily stored away when not in use. It comes with two wheels at the front of the bike. This allows you to tilt the bike forward to move it. You can move it just as easily on carpet as you can on other surfaces.

What’s Not So Good

The Diamondback 5101c requires electric power to operate. That limits its positioning to proximity to a power outlet. The handlebar adjustment is a bit of a hassle, requiring you to undo four bolts. The heart rate monitor is not that reliable. In addition, the seat on this bike is not very comfortable. The console is also quite rudimentary.

Diamondback 5101c Summary

The Diamondback 5101c will provide you with a solid workout, whether you’re after a spin or a conventional cycle session. Its 12 inbuilt programs and 16 levels of resistance deliver plenty of training options. This is an attractively priced spin bike that delivers magnetic resistance, belt drive, heart rate console, and workout programs.

Diamondback 9101c Overview

Features

Self-Generating Power

Unlike the 5101c, the 9101c model does not require a power plug to operate. The console is powered by your calorie-burning energy expenditure. That allows you to use the bike anywhere. However, you will need to plug the bike into a power outlet after first assembling it in order to charge the components. Going forward, you will have to recharge it about once per month.

Wireless Heart Rate Monitor

You get pulse rate monitoring via a wireless heart rate tracker. This is more reliable and convenient than the handheld version that you get on the 5101c. While the bike is fitted for Polar heart rate wireless monitoring, it does not come with a wireless heart strap which must be purchased separately.

40 Pound Flywheel

The 40-pound flywheel on the 9101c delivers a very smooth roll and a smooth ride that simulates a road biking experience. The higher flywheel weight provides you with greater momentum and allows you to recreate the high rpm training techniques that you would find in a spin class.

12 Workout Programs

The dozen workout programs that you get with the 9101c are the same as on the 5101c. That means that you can select between eight customized fitness programs and four heart rate programs.

32 Resistance Levels

With a huge 32 resistance levels, you are able to select more precise settings that are great for progressive resistance workouts. The transition between resistance levels is impressively smooth and natural. The built-in heart rate receiver automatically controls the level of resistance based on your training goals.

Extra Features

The 9101c comes with a built-in water bottle cage and storage department. You also get heavy-duty pedal cranks, multi-position handlebars and custom graphics on the control monitor.

What’s Not So Good

As we’ve already discovered, the 9101c operates from user-generated power. This includes the console power. However, your console information will be lost as soon as you stop pedaling. A number of reviewers have also found the console and heart rate monitor to be unreliable.

Comparing the Two

The Diamondback 5101c and 9101c are both impressive home use spin bikes, with the latter being a beefed-up version of the former. Both bikes provide you with whisper-quiet performance, a high level of adjustability, multi-position handlebars and 12 workout programs.

The two big differences between these two bikes are:

  • the 9101c has a 40-pound flywheel compared to a 32 pounder on the 5101c
  • the 9101c is self-powered whereas the 5101c runs of electricity

With 32 resistance levels, the 9101c also provides you with double the intensity adjustments of the 5101c. This provides you with a lot more precision in adjusting your resistance. It also caters more to the higher intensity requirements of experienced exercisers.

The 9101c also provides you with a more sophisticated and reliable way to monitor your heart rate.

Warranty

The Diamondback 5101c comes with Diamondback’s standard warranty of 3 years on parts and 1 year on labor. However, you have the option of beefing up your warranty cover at an additional cost of $159.99. This provides the following coverage:

  • Parts and labor coverage for 5 years
  • Power surge coverage
  • Mechanical and electric coverage
  • Convenient, hassle-free service
  • Deal directly with Diamondback Fitness, not a third party
  • No deductibles on covered claims
  • Professional on-site repairs

When you purchase the Diamondback 9101c you get Diamondback’s Lifetime Gym Quality Warranty. This gives you a lifetime warranty on the frame and brakes.

Final Thoughts

The Diamondback 5101c is a great all-round bike that provides you with a quality spin workout as well as a dozen in-built programs. This is a solid bike that looks great, provides a smooth, natural pedal motion and is competitively priced. For a more high-end version of a home spin cycle, the Diamondback 9101c gives you an even smoother ride and greater resistance potential thanks to its 40-pound flywheel, gym-quality construction, and self- generating power.
