If you're not afraid of the mechanical bits, something along the lines of the Walmart Schwinns might work. They will need a going through as assembly can be shoddy and the bearings tend to be underlubed. I would imagine the online stuff would be the same deal but would have slightly better equipment.

My Electra or Specialized would be more expensive being Bike Shop Bikes but would be better assembled and come with free adjustments ect but be more expensive. Trek is doing free delivery if you have a Store nearby.
