EL Hefe's Bike
Just so happens Mr President is a mountain biker...
These are crappy pics but the bike is a cannondale rush Carbon with Lefty
and XTR and pretty much everything the best possible.
And it looks like he rides the crap out of it
Tires are worn and sprockets are worn some scratches
And one of the (very large) Secret Service rides a caffeine 29er (the largest mountain bike I have ever seen) The seatpost was about chest height! (Im 5'10)
Imagine the Infamous Black Suburban with a bike rack!
