I built a 36V 350W TSDZ2 Tongsheng mid drive motor with torqe sensor into this full suspension bike with a 36V 12.5Ah battery. The cost of the conversion was under $500 and I was done within two hours. This motor now has helical gears, so it runs very quietly. If you want to convert your bike yourself, note that it can be fitted in the 68 and 73 mm wide bottom bracket positions.
