Full Breakdown
Naperville Municipal Code § 11-4-7-1 defines Class 1 e-bikes as pedal-assist units that cut off at 20 mph, Class 2 as throttle-capable units also capped at 20 mph, and Class 3 as pedal-assist units that cut off at 28 mph. Section 11-4-7-2 requires every e-bike to meet federal Consumer Product Safety Commission standards, display a permanent label showing its class, motor wattage, and top assisted speed, and carry working brakes, front and rear lights, reflective tires, and, for Class 3, a functional speedometer. Modifying a bike past its class limits triggers reclassification or a ban on its use.
Violations & Fines
Tampering with or removing a required class label, or riding an unlabeled e-bike, is a prohibited act under § 11-4-7-4, punishable by a fine of $100 to $500 per offense under § 11-4-7-7.
