I am thinking about doing conversion of my 5 year old bicycle that I use for all season commuting (my commute to work is ~ 9 km one way and takes me around 40 minutes). I also use my bicycle to pull a trailer with my daughter couple of times per week, but only in the warmer months. Now, I did all the measurements and I am pretty confident that BBS02 will fit my frame, but would it survive the winter? Is there any tricks on making it more resistant against all the salt that city puts on the bicycle paths? What wattage for the motor and battery size would you suggest? I live in Montreal, and it gets pretty cold here sometimes, but I live close to the major bicycle path that city is cleaning through the winter. I am about 95 kg ( ~ 210 lbs) and use XL frame.
