Illia ships these motors (ebikes-sf), I could be totally wrong about this, but I remember on a thread somewhere I thought it was concluded that there is not a plug and play solution in terms of being able to just solder up the wires to a digital thermometer etc.. I could be totally wrong on this (and I am interested because I am in the process of getting one of Illia's motors), but I have a distinct memory that the eventual conclusion was that it would not simply be a case of extending the wires and chucking a digital thermometer readout on your handlebars, it had something to do with the type of sensor it was meaning it was more intended as a type of cutoff trigger than something that gave a graduated reading. I know that isn't much help, but I distinctly remember everyone getting excited when they saw you could a motor with a pre-installed probe effectively, but then the conclusion being it wouldn't just give a plug and play solution. I stand to be corrected (and hope so, as I have one on the way).
