I think you did not comprehend what I wrote, so I will quote it for you here, "... you should be able to straddle the bike ...".

Ride, schmide, ... Ever come down hard on your top tube of a frame that is just too big? Ever had to tip sideways to get off your bike. Failing to do so can hurt. Slipping while doing so can hurt - plasic soled riding shoes are a good way to cause this trauma.

The fact that the OP even notices this is proof positive (to me) the bike is too big for him.

Go get a dfifferent bike. Sell this one and get on that fits.

What a long winded explanation of something so simple.

Put on your riding shoes (or something similar, or take off your shoes). Throw your leg over the bike and try to stand erect with both feet flat on the floor while straddling the bike.

1. If the top tube/brake cable is touching your crotch, the bike is too big.

2. If the top tube is much more than 1" away from your crotch, the bike is probably too small (but might be workable, maybe).

3. If the top tube/brake cable are about 1" from your crotch, the bike is just right.
