Hey Y'all,
I thought I would post on the completed conversion since I asked if it would work here a while ago. I went with the 1000W 52V mid-drive motor BBSHD kit and a U004 52V 20Amh triangle battery; it worked out great. Gets me to work and back no problem, Zoom Zoom!
When I first posted what I would like to do, some of you said I would probably need the chainring with the offset which turned out to be right. I exchanged the 42T chainring for the 46T stock chainring with 16mm offset which worked out. I'll plan to get the Lekkie 46T chainring which has a 18mm offset, this stock chainring hasn't given me any issues but I'd feel better using 1st gear with a higher offset. (not that I really need 1st gear anymore lol).
I was unable to get the bottom bracket out myself so I had the bike shop I got the bike from taking it out which made it much less hassle. Once it was all set up I actually had a shop close by to do a proper drivetrain fitting as they were able to make a chain with a more exact length, which made my life a heck of a lot easier, I recommend having a regular bike shop take care of those 2 things if anyone does a conversion themselves. It didn't cost much at all and it saved me a headache.
Thanks for the input on my last post much appreciated.
42T lekkie usually works best w most bike frames, w some exceptions, like your bb issue. also measuring a chain is ez pz. skipping the derailleur, wrap from the large rear cog to front chainring, put the links as snug as possible around the cogs till the links meet and are adjacent, then add 2 links of length, mark the pin, cut it. that simple, for most cases. for full suspension, you make sure to depress your suspension entirely before measuring the chain.
Hi Matthew; which one are you calling “1st-gear”? The largest toothed gear (close to 1:1 ratio to chainring, used for power), or the smallest, used for speed? Thanks in advance.
