I was looking for a decent exercise bike which was well built, quiet and cheap and so i bought the Reebok Z7 exercise bike. Admittedly i did not construct the bike myself but i have it on good authority (my partner) that it took less than 30 minutes. It is sturdy and seems well built, the seat was abit uncomfortable at first but i think it just takes abit of getting used to. The bike is reasonably quiet when used which was a must for me as i wanted to watch tv whilst i exercise. The display buttons are big and chunky which is great but they do feel abit cheap. You can found out your heartrate, calories burned pretty much anything you'd expect as standard for a exercise bike but i was abit disappointed that there doesn't seem to be any actual programs you can select. Overall a decent bike for anybody who just wants a basic keep fit bike they can jump onto and use for 20 minutes a night or so. I bought this bike from Sweatband (through Amazon) and must say delivery was very quick and there were no problems whatsover.
