I'm trying to find a replacement bottom bracket axle for an old pro rider e bike. it's 155mm long plus threads for bolt on cranks. it is 40-65-50, can anyone help I can't find such a thing anywhere.PXL_20230624_154738866.jpgt find such a thing anywhere.
 
Do you require an exact replacement for just the shaft?

Do you also require the threaded-bolt ends, or can you use the more common threaded-hole ends?

Or can you use a "standard" cartridge BB that includes the bearings, caps, and shaft?
 
I don't know much about bikes, but are you sure it is an 80mm shell? Doesn't seem like a standard width.
And, what is wrong with the shaft?

The shaft is bent on the left side. The shell is 80mm wide I presume to accommodate the battery mounted behind the seat downtube. I measured the shell only, without the bearing cups screwed in, I think thats right?
 
That is the very part Chalo, it's just on the wrong side of the atlantic from me! I'll go for it if I can't find one this side many thanks.

HI, I guess I could use the threaded-hole end variety if it uses the same cranks with tapered square holes. Also I presume a cartridge bb would suit as long as it fits the extra wide 80mm shell.

Yes, that's right. And as usual, I'm wrong. As for a cartridge style, the US Radwagon 4 uses an 84x154mm; they don't sell online but will if you call.

Thanks I'll get onto that, my options are limited on this one!
