All the bikes should have one installed from factory. But greed is a powerful desire. among big corporations.

This case is nice a thick on the back. The device fits snuggly into the case. The flip cover is very secure when closed as the magnetic clips are very strong. My daughter loves the color. We've only just received it, but it seems to be a quality case thus far.

Always looking for alternative ways to get a good workout in and this is a great way to do it! I found the workout to be challenging, and it also kept me engaged the entire time. Can't wait to continue to use this and build more strength.

I didn't realize how heavy duty or colorful this agenda would be. Its better looking in person. I'm glad I purchased this AND it shipped and delivered in 3 days. Great service!

My little guy loves cheese and pasta so we really try hard to keep him from getting backed up. This is gentle. We add a little to his evening milk and in the morning he is a happy camper.
