    Purchased the Proform 400, but when delivered to my surprise it was the Proform 500 an upgrade for whatever reason. The only difference that I could find is the 500 has a tablet holder on the handlebars. This is a very well-made spinner bike, it came with a 6mos. IFIT subscription, easy to assemble and yes the seat is narrow but thats the standard seat on the 10-15 speed racing bike. To correct the seat problem, you can purchase an inexpensive wide seat pad cover thatll fit.
