Could someone who has a Costco membership find out about how much the Schwinn Seneca and Traveler bikes weigh *rough guess is fine* For the price of those bikes, I'm leaning heavily towards them, though I'm considering all of these bikes.

I'm sure most of you would say get the Trek or Fuji, but I feel any bike I get will be put together roughly the same.

Schwinn Traveler - $220
Schwinn Seneca - $260
Schwinn Varsity - $200
Trek 7.2FX - $430
Diamondback Insight 1 - $200-400
Windsor Stratford - $400
