I've put about 2500 miles on my Ebike since converting it to the BBSHD and man-oh-man does this thing like to explode final drive parts.
To date I have destroyed:
Nexus IGH 3-speed (don't even bother with this, it blew up so fast)
2 Shimano CS-HG20-7 Cassettes (exploded 7th gear and broke teeth of gears 3 and 4)
SRAM PG730 Cassettes (exploded 7th gear)
3 SRAM Chains
2 KMC Chains
Lekkie 42 tooth chainring (spectacular parts explosion, props to lekkie for sending a replacement though)
When I say destroyed, I mean shiny metal parts on the ground, not just simply worn.
So, the question I have is, is there anyway to make these parts last more than a 3 months? I have read that some of the 10 speed cassettes/chain combinations might work (here:https://electricbike-blog.com/2017/03/05/beat-on-me-i-love-the-abuse-shimano-cs-hg62-11-36t-10-speed-cassette/) but I don't have the parts for a 10 speed and that article says he only has used the hg62 for 2 weeks. The HG62 is also kinda hard to find new.
I'm 175 lbs and the BBSHD is running 1500W, so there are some resonable forces going into the rear cassette and chain. I don't shift under load, the bike has a gear shift sensor to prevent this.
Has anyone found a combination that works? Help!
