Dear e-bike tuner, this is a Sync Drive Pro 2018 motor by Giant. In order to tune it, you have to remove the covering and unscrew the motor This is very complicated in this case. It is the most complicated motor I had so far It can take a while. At first, we have to remove the crank with a 8 mm hexagon wrench So, then the crank extractor Now we have to remove the two chainrings with a Spider Tool by Giant, which I bought in the Giant store It looks like tghis You need a 35 mm wrench for this and then you have to put this here, and then hold the back brake and then turn it clockwise with the wrench It is released now And then, of course, you have to remove the chain Then turn it clockwise Then you can remove the whole thing Now I have to loosen the screws here You need a Torx 20. Here are two screws which I have to loosen with a 4 mm hexagon wrench Now this is removed Now I loosen this At first, I have to remove the crank Then 4 mm hexagon wrench Torx 20 Another one Another one Now I have to remove the battery And with the Torx 20 you have to screw in here Don’t remove it completely, but only so far that you can lift the plastic thing Now you can lift this It looks like this. You see the screw here Now I screw it again. Then I have to remove the cover here Now I need a Torx 30. Loosen the screw first Then loosen this one You can wrench it as usual Now I lay down the e-bike I have to loosen this screw using a Torx 30 This one, too Now you have to remove the cables Then you can just swing out the motor, take it out and lay it down Then you can remove the cables We have the cable loom here The red one goes to the battery You mustn’t touch it. This one belongs to the battery as well, there the current flows. This is the CAN Bus This is the light, it is a 2-pin connector 6 Volt This is the speed sensor, it runs from the back into the frame, there to the 3-pin connector and then into the motor It has three cables, of which we use only two And then here the 8-pin connector it runs upward to the display And this is the CAN Bus and so on. The next step is to put the module in again and then to reassemble everything.
