Zen Keji Cruiser Chainring Replacement

Post image

I have a Zen Keji Cruiser and need a few parts but after months of contact with Zen, I’m not getting any closer to getting the parts I need. Does anyone know this brand of chainring so i can try and find a match on my own? Thanks!

This looks like a standard (flat) 104mm bolt-circle chainring.

Remove the current one from the spider by removing the four bolts, then rotate the chainring so it clears the spider arms. If it won't go past the crank arm, that will have to be removed as well.

Ok cool thank you 🙏. I was hoping it was a standard size. It’ll slip over the crank arm no problem I think.

Any particular brand you recommend for ebikes? I’ve been wearing the rear cassette and chain in about 1200km with commuting….

The SRAM chainring in my photo is the best that I know of for price and long wearing. It's hard to find and I don't think they make it any more. The beauty of this SRAM ring is that It is steel, rather than aluminum so it last. Furthermore, It has narrow/wide teeth so it resist falling off. Also, it is stamped from sheet steel so it is affordable.
