Quality and Durability

This Diamondback 910Sr Recumbent Bike is comparable in durability and quality to professional equipment that costs more. 

Its components are steel-crafted, ensuring a quiet and sturdy ride. The flywheel of this Diamondback 910Sr Recumbent Bike is solid steel.

However, it is still advised that you always wipe the recumbent exercise bike using a mild soap solution and then dry with a clean towel. Remember that perspiration can be corrosive if it accumulates a long time in the machine.

Workouts and Exercises

Compared to other cardio equipment, a recumbent bike like the Diamondback 910Sr offers a more comfortable exercise. This is because you’re sitting back in a semi-reclined angle that you feel the exercise is not intense but is effective.

Of course, you can perform easy cycling that requires an exertion level of 1 to 2 out of 10. You may also do a moderate effort of exerting 3-5 intensity. 

Should you prefer a hard pace pedaling in this Diamondback 910Sr Recumbent Bike, then focus to achieve an exertion level of 6-8 out of 10. You can alternate standing and sitting approximately every half an hour. The other option is to alternate the easy and hard pedaling.

These workouts are for all levels:

  • Efficient pedal stroke – strength and cardio for higher levels
  • Speed intervals – takes your heart rate to a different zone every three intervals
  • Cycle fartlek (continuous) – alternate between moderate to intense pedaling
  • 25-minute immediate intervals – a structured routine

Don’t forget to warm up at a comfortable pace before starting any of the above-mentioned workouts.

Who is it Best for?

This is best for avid outdoor cyclists who enjoy lower body resistance workouts. People who like to be comfortable in their workout sessions, regardless of how long or short the exercise is, will enjoy pedaling the Diamondback 910sr.

A recumbent bike may also be ideal for people who have a back problem that does not allow them to exercise that much. With Diamondback 910sr, they can burn calories like an upright bicycle would but without the risk of getting their back hurt or strained.

What Do People Say About it?


Williams shared on Amazon that he did his assembly of the product and it gave him a “feel” for the quality of the product. 

“Pedaling is smooth and quiet and transition between resistance levels works very well with no bumps or grinds.” He added that the back support is also very good.

Another Amazon user, who did not indicate her name, reviewed that the pros of the product are that it is quiet, has a large screen, and accommodates her 5’4” height that her husband’s frame.

The Diamondback 910sr’s phone or tablet holder, however, is a con to her. The construction is a “big risk” she’s “not willing to take,” sharing that there’s a possibility an expensive phone could shatter in pieces when it hits a wood floor during the workout.


Bob Carlson shared on YouTube that controls on Diamondback 910sr are “nicely laid out. You got things, like your heart rate, intervals, strength indicators.” When he began pedaling in the recumbent exercise bike, he said, “there are no bearing noises, no issues, nothing.

Stevie Richards also reviewed the recumbent exercise bike. He said while “the instructions were not that easy to understand,” he can adjust the back seat since he and his wife have different heights.

Pedals are really nice. I’m gonna say, it’s a nice magnetic resistance recumbent bike. Just as smooth as the ones that cost a lot of money,” he continued.

Bottomline: Should I Try It?
