Stamina Mini Trainer Bike with Smooth Pedal System, Blue

I am a healthy, active, 5 foot tall, 110 pound, 71 year-old Grandmother who purchased the Stamina Mini Exercise Bike to meet my need for exercise in the winter, when daily walking out of doors in my climate is unsafe. It has exceeded my expectations. I am able to do sustained 30-minute pedaling sessions at 115 revolutions per minute. It was easy to assemble. Other reviewers have mentioned a problem with pedals falling off with use. I have not had this problem - I check for tightness after every couple of uses and there has been no loosening of the pedal connections. Others have mentioned that it 'creeps' away from them on the floor with use. I use it on a stationery mat and it stays put. I would recommend this product.
