Received the radrunner 2 and the rear wheel wobbles at full, i had the rim trued up and have the same results!
Anyone no what the torqe is supposed to be on the wheel nuts, only thing i can think of?
Torque on the main rear wheel bolts is 40NM or about 29.5 ft lbs.
The bolts are hollow on one side do not over tighten.
Make sure the tire bead is seated evenly around both side of the wheel.
Just a guess but I would also check the Torque Arm.
