With the fork braces I feel more confident applying the front brake.Bicycle forks have a curve in them so they act like a leaf spring.I converted to disc brakes by welding a bracket to the fork leg.so when you brake it is applying a opposite force to the fork leg.With the braces I just have more confidence.If the forks do snap they may give me warning now.I love the xiongda motor.And my batteries where £34 each,I use 2.I went on a 75 mile trip using 6 and still had power left.I lot of this trip was in level 1 assist.
