Looks nice but falls apart

Bike rides nice and feels good but will fall apart on you after a few months, do not ride on anything other than completely smooth pavement or it will shake it brakes and derailleur loose

Great beginners platform

Is not "plug and play fender" compatible but DOES have standard fender and rack mounts. This does NOT have the plug and play holes w/ set screw on higher level Specialized bikes. Terrible micro-shift components. Otherwise good starter bike.

Lovely bike and easy to set up. However, I had to pop into a local cycling shop and ask them to modify the gears on my first ride as they kept slipping. Now it’s lovely and smooth

My Dad has macular degeneration

My Dad has macular degeneration and has absolutely no central vision. He can only see with his peripheral vision. As I ride my specialized bike next to him, he gets to ride a bike once again and he is amazed by the feel, the ease and the joy of riding that beautiful bike. We defy the odds daily and specialized has helped my Dad regain independence and awesomeness again and again. Great bike!!
