I'm visiting from Germany at MIT till beginning of September and I'm searching for a used Dirt Bike I can use for riding around in the city and work on my biking techniques. I brought my Trek Slash 8 with me from Germany but that's definitely not for this purpose.
The Bike should be 26" and good for my 5,9 ft.
Doesn't have to be anything special or fancy as I can't spent much for it (max. 400 $).
