>>2041180Contribute a USD$3 (they do get that cheap, shipped through Aliexpress) speedo install on my scooter. Works, the small diameter programmed in with no problem and it fits and signals pic related. Needed a wire extension however with somewhat tricky soldering. I did this more for odo than speedo. One thing I don't like the battery is an AG10 which is tiny - I feel its going to materially affect utility.
