The wheels could be a problem- but then I am not a lover of machine built wheels. Have a chat with the LBS and see if you can upgrade to a better set before taking delivery of the bike. If that is above your cost- then get the wheels de-tensioned and reworked before taking delivery. A good wheelbuilder can work miracles on even the most basic of wheels.

And this would be the same suggestion for both bikes. Spoke count for a heavier rider does come in play when buying but if the wheels are rebuilt, then 32 spokes would not be a problem, however 36 spokes would be better.
