Back and neck problems preclude my use of typical road or mountain bike geometries. I want a bike that I can ride in a fairly upright position, but I don't want a clunky cruiser, fat tire or similar bike. All the hybrid and "fitness" bikes I see from the major manufacturers still require too forward of a body position. I don't want drop handlebars. I do want a relatively light weight, responsive, multi gear, skinny tire, efficient bike. I won't need suspension. This will be used mostly on relatively level ground or gently rolling hills. I'm not interested in a recumbent. I'm not concerned with aero efficiency, I won't be racing. I do want to pedal at a fairly high RMP and relatively low rolling resistance. So basically I want the powertrain performance of a road bike, but with the upright riding position of a cruiser. I expect to pay for performance but would like to keep it around $2-3K in price at the most, probably would not consider anything lower than $1.5K. Anyone have any suggestions?
