You get a lot of bang for your buck with this exercise bike. The screen mirroring works great and the huge monitor & speakers is a great touch. I can easily crank out about 8 miles or so per 20 min session, & more on a 30 min session. I bought an annual subscription to the Yesoul Fitness app, and normally just run open world 20 & 30 min courses. This bike does work with other apps just fine, but I prefer the Yesoul Fitness app, or just watch You tube videos while riding. I have stuck with it every day, and getting my miles in before breakfast every day has worked out well, and I feel better for it. This bike is built well, it is quiet, and everything works well as advertised. I especially like the magnetic resistance. I'm very pleased with this bike, and when compared to much more expensive models, it's a smart purchase in my opinion.
