Wheels

Even if we go to the experts, we need to know how to take off the wheels, especially the back wheel which has a hub motor and wire leading to it.

Remove

TODO - Suspect it will require removing the entire wire and routing to the controller.

Real Wheel Alignment

I found the rear wheel out of alignment with the bike. I can’t seem to see an obvious way to actually measure this. When I look at the swing bar I could see the offset easily.

Turns out the reason is fairly simple, you can’t lock it all the way to the back of the swing bar, or the brake rotation bar won’t fit onto the swing bar. When I first tried to align it, I hadn’t realised that wasn’t sitting correctly. Second time I moved both nuts forward on the axle about 5 to 8mm from the back of the swingbar.

Once in place, and making sure the brake rotation bar was in place correctly, I both checked each side of swing bar and a visual alignment down the tyre. Tightened both internal nuts, then the lock nuts, then finally the smaller 10mm screws designed to stop rotation. Note these last ones are poor mild steel and very easy to over tighten, so be careful.

Have a look from the rear to see if you think the wheel is aligned. You can also look at the gap at the back of the swing bar

Put the bike on a rear stand, e.g. one that holds the wheel flat and off the ground. Swing bar stand.

Loosen the outer nut first. I had to use a metal bar connected to my ratchet driver as I didn't have an impact driver. Then loosen the inner nut, you have to loosen it a few turns. Don't forget to loosen the smaller screw (stops rotation).

Repeat on the right side. When you tighten everything up - make sure you are careful not to overtighten the smaller screw - it is mild steel only. Also make sure the inner nut is screwed tight first. How tight. Very tight. I don't have the specs as they are not released. We need to push Braaap for better maintenance information.

Be very careful to make sure the brake arm (stops rotation of the caliper mechanism) slot is in this holder.

Now tighten everything up and manually check the brakes. Then start the bike on the stand, spin the wheel (not too fast, keep it undr 100kph) and test the brake further. Did I mention you should check it is tight and that the brake is working. Good.
