Finally some quality tools to fit your motor to your frame!
The Lekkie Four-42 Socket is a full CNC 7075 T6 4-notch socket, designed specifically for Bafang BBS motor fitment. As hard wearing as it is beautiful, this socket will last years and years of motor installs.
With both 3/8″ socket tool engagement you can easily use a torque wrench to get those lock nuts tighten up to spec. Or use the 32mm hex if you don’t have a ratchet.
