Bike size issue

I am 6' and 240 so yes a bit of a belly. I bought a Trek DS3 a few months ago. I chose the medium because the sizing chart on the Trek site seemed to indicate it. The Large seemed too large.

I can pedal OK but my main issue is that no matter what adjustments I make, the upward motion of cycling ends up with my thigh touching my body/belly (i.e. my phone in my front left pocket/my wallet in my right). Is this normal? I went back to the bike shop and the guy seemed to think so but he is rather biased.

Well certainly if you have a low hanging belly and you have bulgy objects in your shorts, there is definitely some potential for contact.

Do you have long legs and a short upper body? Maybe your position is a little bit more forward leaning…..i.e. the seat is high but you have to lean forward. If it really bothers you, you could try a higher position with a higher stem which will allow you to lean a bit less.

There is a specific way how to install/tighten the headset stem properly if you do want to install it yourself.

Did you even tried the large size bike to see how it would feel? And I mean ride around the block with it.
