Why do we use a Double Walled Rim and heavy duty 36 Gauge Spokes?
In the beginning we tried various kits and many of the brush less motors were very good motors. The problem with most of the conversion kits available are that they are spoked incorrectly, use a single walled weak rim., have spokes that are the wrong length causing the spokes to be bent in an "s" shape. Simply put bicycle wheels were not made for this type of torque on them and on occasion you will need to tighten your spokes until they finally "seat" themselves.
