Hanger, not replaceable.
biggest upgrade IMO, headset!
Second upgrade, bottle holder on sear tube
As to who buys these... covering the purpose of a mini velo I think both sets of riders will consider a purchase. I was never a BMX riderbut a road, MTB rider who is now thinking of a bike which will go well in a smaller space and travels in less space. I don’t want to drop bar my folders which is another reason I like this Nano.
