I own an FX+ (just like MK313) and use it to commute exclusively since mid-June when I purchased it. I've logged over 1100 miles, a feat I never saw myself accomplishing. I purchased some rear panniers (Ortlieb Bikepacker Plus) and a phenomenal light kit (DesignShine DS-500 tail light & DS-1300 headlight) that allows me to commute in the dark wee hours of the Chicagoland morning (~5 am). I'm sure there are people that will ridicule or scoff at the fact of electronic assist (matter of fact, I work with a few of them and they have the "Body by Brunswick" i.e. bowling pin physique but yet are ready to chide me for my new-found hobby) . . . my advice is to ignore them. I've lost 30 lbs and have increased my stamina. I don't use the assist as much as I did in the beginning but I still use it for crossing busy intersections, hammering up a steep hill or when I'm exhausted and I have to return home in a headwind. It also allows me to commute in a timely fashion to work - only adding about another 15-20 minutes to my normal commute.

My advise is to give it a try. You will definitely feel like a kid the first time you kick in the assist; I guarantee a big smile will appear across your face!

Would I have accomplished 1000 miles or continued commuting solely by bicycle when it was cold, wet, etc. - hard to say. Its been a paradigm shift and I'm not looking back! I'm contemplating the idea of commuting year-round so now I'm looking to purchase studded tires. As far as weather concerns, I've been reassured by Trek that Bionx is well-designed and sealed from the elements - there is no problem riding in the rain/snow.
