Yes, it is.

What is the flywheel weight of the 510Sr?

It weighs 14 lbs. However, the 510Sr is engineered to use frictionless magnetic resistance that is electronically controlled. Therefore, the flywheel weight isn't as important as it is on bikes without magnetic resistance.

Always wipe down the unit with a mild soap solution followed by a thorough drying with a clean towel.

Verified Review for 510Sr Recumbent Exercise Bike

It is just the thing we needed for my elderly mother to get some exercise at home. We especially liked the adjustable horizontal bars in front of display (do not block) for support when getting on and off. Ordering was easy. Directions to put together easy to follow, though needed a couple of modifications to a couple of order of operations. Helpful to have a moving dolly available to get from truck to final location. Very pleased with product

Yes, I recommend this product.

Great bike

I've had this bike for 18 months. My wife and I use it a combined 6-7 times per week. It's an excellent bike, the work-outs are comparable to the ones we had/have at our gym but at our house. Very reliable, really thrilled we purchased it. It saves us a ton of time when we are trying to get week-day AM work-outs in before getting to work as it's impossible to juggle that with work and kids, etc. I highly recommend it. Pros: Sturdy, reliable, commercial quality

Yes, I recommend this product.

great bike

Highly recommend, had great experience with first Diamondback, 14 years and gave it to charity, this bike is even better, very solid, like pro machine. Pros: had a Daimondback upright for 14 years, used it almost every day, this recumbent is even better, very solid, like a professional machine. Easy to use, preprogram profiles/workouts.

Yes, I recommend this product.
