When I bought my current hub motor I had to buy a free wheel sprocket assembly to use with it. I have put a lot of miles on it over the passing years. The teeth on the sprockets are still in fine shape, but the bearings and races are screaming at me to be replaced. It slips, grabs, locks up and sounds like a threshing machine when it acts up. It is worn out and badly in need or replacement. The problem is my 9 speed unit is no longer easy to find. I have been getting by continuing to use it thanks to taking it apart and oiling it well. But it really needs to be replaced. Finally I found one and ordered it. I am just hoping my current one won’t leave me stranded somewhere as I am continuing to take my daily rides. My new unit is suppose to arrive about the middle of next week. I wish I could use a newer unit … a cassette instead of a free wheel, but alas it is not to be. And 9 speed is old tech and getting harder to find. And beggars can’t be chooses when it comes to selection. I would like to get an 11-36 tooth unit, but all that was available is an 11-32 which is what I have now. I had changed to an 11-36 rear cassette on my Catrike wheel to help with hill climbing but when I bought my e-motor all that was available was an 11-32. As time goes by it is getting bleaker. I am just glad I was able to find an 11-32. Hopefully it will last me quite some time helping me to …
KEEP ON TRIKIN’
I don’t know what I would be up against if it needs to be replaced again.
UPDATE — I got the new free wheel installed today (12-17-21) and wow … what a difference. The brand new free wheel is like brand new!
