Yeah, I saw a few different gearing setups on Amazon, just figured it was the single speed.

I personally wouldnt like a beach cruiser for 20mi rides, but everyone is different. If you enjoy the look and body position, then by all means its probably a great way to get started riding with your family.
That is whats most important in the end- getting out and doing the shorter family rides. So much to see, explore, experience, etc.
