A used mountain bike, otherwise in good condition (maybe needs a bit of oil on the chain). If wanted, there is a lock and a basket included! Sizewise it is more on the smaller side, so it is probably good if you are not huge (although I am 6'2'' and it worked for me).
Low price since I am leaving Stanford and would like to get rid of it.

If interested please contact me via gtristan@ethz.ch

Cheers,
Tristan
