Lekkie 1TSNUTS – TONGSHENG LOCK NUT

A single locking nut for Tongsheng TSDZ2B installs

Installing a Tongsheng TSDZ2B mid-drive usually means hunting for a tool to tighten the main bottom bracket nut that hardly anyone stocks. On 73mm bottom brackets you also run into a second problem: the Tongsheng cover won't fit. The Lekkie 1TSNuts solves both with one CNC-machined aluminum nut.

It tightens with common tools, and once it's torqued, two grub screws lock it to the bottom bracket threads so it can't loosen or rotate. That's a cheap insurance policy against a loose motor, and it costs less than buying a dedicated Tongsheng tool.

Tools that fit

• Lekkie Sixteen-44 socket
• Shimano-style 44mm 16-notch bottom bracket tool, wrench type (e.g. Park Tool BBT-9). Most sockets are too shallow.

Running a Bafang instead? You'll want the Lekkie Onenut.
