"Hi John,You are on the ball. We have tested a wide range of bike and on our prototypes we have an adjustable rake/offset. We will have one setting in the end which will be tending towards slower and more stable handling. The effect of the battery being positioned behind the steering axis in combination with the motor's centripetal force and the fact that it is pulling, counters a lot of the weight on the rack itself. Once moving the handling is very stable only a little heavier. Keep on rolling,HUSKY Bike Tech Team"
