I have purchased about five different types of these motorized pedal exercisers and the majority of them fall apart within a month or two of use. But I generally do around twenty miles each day with them. They all only will run for thirty minutes at a time and no longer. I run mine at the highest speed which will get me around 3.360 steps every thirty minutes which averages out to about a mile and a half based on the 2,000 steps per mile.
