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.

I bought my motor battery controller as a kit online from Aliexpress. I also ordered some cables and the kit for hydraulic brakes, because I changed conversion bikes I was going to convert an older 1995 mountain bike but decided I wanted hydraulic disk brakes, plus a 1X drive train. I also bought a programming cable online from Aliexpress.
The only thing I bought from North America was from Johny a 36T lekkie ring. I think I was his first Canadian delivery
I did speak with the fellows at Golden motors they were excellent.
https://goldenmotor.bike/ I would recommend them.
which bafang distributor would you recommend in Canada?
I live about 16Km east of Edmonton and I have put on the BBS02 750W motor, I did install the 350W sticker because as someone mentioned who is going to know except me.
I do ride a non-ebike in Edmonton in the winter, whatever they put on the road here is pure hell on chains. I destroy at least one chain a winter.
I am working on waterproofing my e-bike. I am not worried so much about the motor but, connectors, display and battery.
what about all the cables and battery connectors?
^ what he said. also the motor is IP 65 rated so pretty water resistant, salt meh, no way its getting inside the motor. just clean your chain/cogs often
As for Canada regs of 500w, the BBS02 motor kits I buy all have a set of stickers that you can put on the motor that indicate the BBS02 motor is 250w. I doubt anyone would know the difference frankly.
I don't see any reason the BBS02 wouldn't survive some cold weather. You will get a bit less mileage out of your battery when it's colder though. As for the cable routing, I've had customers bring in bikes for conversion that had routing in the same manner. The front derailleur cables are removed as part of the conversion so that is not an issue. For the rear derailleur cable, I typically removed the existing cable and re-route it entirely via new housing on the exterior of the downtube and back to along the chainstay. It has worked out fine.
Another question, I realized that my gear cables are routed under the bottom bracket, would it be in the way of the motor?
500W in Quebec, unfortunately.
a BBSO2 750w would do you well, plenty of power, but you may want to check canadas regs if you care, not sure what their limit is. battery capacity depends on the range you want. 52v 10Ah may get you about 20-30 miles tops with pedal assist, and not be too heavy for a battery. i doubt the salt or cold would affect the bike in any way - fenders should block most of that. you want to avoid rain and moisture getting into the battery ports or display so you can cover those with a plastic wrap or tape when needed.
