Over 16000 km since April 2020, so far so good )) I use it for my daily commuting, all 4 seasons, good weather, bad weather, sometimes for bike touring. It is fun to ride and i love all the features I've got using GrinTech products: regen e-brake, back pedaling braking, electronic freewheel, pedal assist, throttle, the control and monitoring of all parameters. With the MF Switch i control the PAS level.
All the parts where purchased at ebikes.ca:
*Cycle Analyst V3_WP
*Multi Function Switch
*Throttle
*Baserunner L10
*36V 19Ah 21700 Downtube Battery
*Tripple Bob
*L1019_M cable for the motor
*Cycle Satiator Charger
* Thermistor 10K
*PAS_12P
*Sate-lite 1.5 Watt Ebike Light
*Sapim spokes
This conversion was inspired by the YouTube video posted by Justin:
How to Salvage / Hack a BionX Hub Motor for External Controller and 3rd Party Batteries

I have followed all the steps shown in the video and successfully salvaged this BionX motor. Here are some advice from my experience:
*If you don't have the gear puller and you live in Canada you can loan it for free at "Canadian Tire" thru Loan A Tool Program. This one you can see in the images is a 7 ton gear puller.
* To remove the torque washer from the axis i made a DIY bracket from a L-shaped steel angle since the gear puller jaws were too thick to grab the washer
* Don't forget to insert the cable thru the lid and the bearing before soldering the wires as Justin did )))
* The Speed sensor wire in the L1019_M cable can be connected to one of the outputs of the hall sensors. I made a mistake assuming the speed will come from baserunner since the 3 hall sensor were connected but it turned out i have no speed indication after i assembled the motor so i did a small cut in the cable and connected the wire to a hall sensor wire because i didn't want to disassemble it again.
* Check the bearings maybe they need to be replaced too since the motor is already disassembled. Mine were marked 6003 LB wich is a 17X35X10MM sealed ball bearing. I've replaced them now after 16K kM, who knows what mileage they had before.
As for the performance you can get from BionX PL350 motor - i have compared my real data, speed, consumption with the Motor Simulator and Trip Simulator available in TOOLS section on this site and they are pretty accurate.
The motor is not very powerful but good enough for a comfortable ride. I can give bursts of 700 - 1000W without problems as long as i monitor the temperature on CA. For long term power - up to 350W is ok, higher it tends to overheat above 90 deg C especially during summer heat. It is not very effective for steep uphills. The average consumption is about 8.7W/km if i set the power level at 200W-275W and 11-13W/km at 350W (700x35C tire)
With my 36V battery i can reach 35-42 Km/h. Usually i ride it at 25-30km/h with 250W PAS level.
Good luck with your projects!
