I ran a search here on BF for Bazooka and did not find much. As a 6'4" rider who needs to ride a train that does not permit full size bikes, this appealed to me. they claim it's 36 lbs, which is manageable IMO, especially for a bike this big. I'd consider switching out the handlebars and the seat and removing the rack to lighten it a bit.

I really like the internal gear... what I really want is a vitesse D7HG, but it's pricier and would really be on the small side for me.
