The only hard part about the Bafang BBSHD or BBS02 installation is you need a special wrench to install them.  This tool set has been custom machined out of stainless steel  to make installing and tightening the inner and outer rings on the BBS02 and BBSHD easy.  If you are an ebike shop you will probably want these tools so you won't have to risk scratching the paint on the units when installing them
