I'm about 245 and ride a roadie no problem, even with the 700 X 23 tires. If you'e on it for weight loss, I'd say go roadie. You'll do longer rides. Short rides on a heavy bike are less aerobic compared to doing 100 on a roadie.
Hybrids are cool for short rides. Roaides are great for handposition options contrary to what most beginners believe. Get a roadie and a good strong back wheel.
Losing weight means pushing yourself past limits, effort , distance etc.
I have see some rides kick butt on a hybrid but most end up wanting a roadie in the end. Cut out the middleman!
