If I repeat myself, maybe you'll pay attention to the pertinent bit of my post this time...
Just because you can do it, that doesn't make it a good idea.
Crazy stuff like riding a Boris bike up Ventoux or doing LEJOG on a gaspipe special are ridiculous examples of what these bikes are "capable" of, but don't exactly constitute helpful advice to people who live in the real world. The OP isn't looking to get an appearance on Ripley's Believe It Or Not, he just wants something to commute on.
