I ordered two cranks off aliexpress, one from "electric bike house" was for a bmx 152mm new crank. I got a poorly wrapped, scratch/used (pedals mounted) 170mm really ugly crank, and also another vendor for a Lasco 165mm 46T crank. I did receive the lasco, shipped well, but 40 days later, 170 mm (instead of the 165 ordered) and 48T (not the 46T) I ordered. Not worth the headache. I'm disputing the order with "electric bike house", and going through the dispute process, they lie like a rug. YMMV.
