Which exercise would be best bang?
 

Hi. I am looking to buy a preowned exercise bike. I found 3 in the area, all selling within $200 range. Not sure which one would be best. I would use it primarily for HIIT cardio.

- ProForm TDF 1.0 ($150)

- Sole SB700 ($180)

- Life Fitness CLSC Integrity ($200)

Proform is the most fancy, not sure if I'd really use the smart features. The flywheel is 20lbs and it has SMR (magnetic resistance)

Sole is a solid spin bike without any bells and whistles. The flywheel is 48lbs and it has felt pad resistance, although high quality.

Life Fitness is a commercial bike. It has the most features, its the smallest, has magnetic resistance but it does not list the flywheel weight. It is self powered so no AC cord is required. Although it is surely high quality as the weight capacity is 400lbs.

Which of these would you recommend?

Im not familiar with any of them, but can you try out each one and see which one feels best to you?

Well all of these are not good to be used with apps like Zwift. If you really want to use them doubt they would keep your attention for long
