As it is the only front chain ring, a narrow wide tooth pattern can be used to eliminate chain derailment and increase durability by thickening the teeth. At a fraction of the weight of the stock steel rings.
The smaller chainrings than the original 46T are perfect for hilly areas and increase the efficiency using smaller gears. The end speed using the throttle is still high, because the motors spins faster. The big chinrings allow to pedal also at high speeds.
