I've been Googling this for weeks and can't find any 160mm long cranks with an ISIS drive interface. They are for the rear of an e-tandem with a Bosch motor. Easy to find short e-bike cranks but I need cranks with a spider for the timing chain ring.

Thanks Paton but all the above seem to be E:bike cranks without the option for a chain ring. Tarty bikes link appears to be some sort of trials bike cranks with freewheel options and I can't see any that take a chainring with lock ring........A bit confusing TBH but the crank shortening option does look like a goer to me so I'll probably investigate that one.
