Not sure where to put this, but I'm going to herein attempt to document the steps needed to program a QSmotor SiAecosys Taizhou CT-22 digital speedometer, which can, and is, used for eBikes, eMotorcycles, and eScooters.
The SiAecosys CT-22 is an ostensibly "high end" speedometer in that it is both of high quality, water resistant, and can be programmed -- while offering lots of functionality. It should not be considered "plug and play" in that it will almost certainly require many small and varied changes and extensions to your current wiring. Further, the so-called "documentation" provided by QS/SiAecosys -- while superior to anything I've seen from any other speedometer vendor on AliExpress -- still leaves much to be desired. In particular, the programming interface appears to be written by a mashup of Albert Einstein and Alfred E. Neuman.
In this post, I will provide a melange of instructions: the as-supplied-by-the-vendor's Chinglish, the original Alfred E. Newman Chinese, and a Google translation. I do this in order to attempt to iteratively (with your help) make sense of this well-made but otherwise difficult-to-understand contraption.
P.S. the original "documentation" provided by SiAecosys can be found here for your reading pleasure: http://www.siaecosys.com/upfile/201908/2019082255434357.pdf

P.P.S. apparently a proprietary version of this speedometer once graced the 2014 and later Zoro motorcycles:
