Surprisingly plain vanilla bikes the Biden’s are riding, plain old rim-brake Treks, mediocre quality stock wheels. Even the cage pedals are decidedly retro. Bicycles of people not really into bicycles, stuff that sits in a garage for years.

Hard to tell what level of quality bicycles the Secret Service muscle are riding.

"...if the gentlemen of Virginia shall send us a dozen of their sons, we would take great care in their education, instruct them in all we know, and make men of them." Canasatego 1744
