Dear Mr. Townley:

This is in further response to your letter of November 24, 1992, asking for "an advisory opinion that the Yamaha Pedal Assisted Bicycle is not a 'motor vehicle' or 'motor driven cycle' within the meaning of the Safety Act and regulations promulgated thereunder." Previously, we had acknowledged your withdrawal of your request for confidentiality.

The Yamaha is "a bicycle equipped with a battery powered pedal assist system that engages when the system senses 'kicking' torque between 5 Kg and 50 Kg, such as when the bicycle is starting from a stop, or climbing hills." It is intended to facilitate standing starts in traffic, assist in climbing hills, and to "keep up the pace when a rider becomes fatigued while commuting, running an errand or exercising. The system is designed to engage when the driver is actively pedaling, and to disengage when the speed is less than 1.24 mph or more than 15 mph, when torque at the pedals is less than 11 lbs or more than 110 lbs, and when the braking system is activated. The photographs you have enclosed show, in all important respects, vehicles configured as conventional bicycles.

The National Traffic and Motor Vehicle Safety Act (15 U.S.C. 1381 et seq.), defines a "motor vehicle," in pertinent part, as "any vehicle that is driven or drawn by mechanical power, manufactured primarily for use on the public streets, roads, and highways." (15 U.S.C. 1391(3)). On November 6, 1974, the Consumer Product Safety Commission asked the agency whether a "motorized bicycle" was a "motor vehicle" if it utilized mechanical power to propel it "only some of the time." NHTSA replied on December 6 of that year that it considered motorized bicycles to be motor vehicles subject to its jurisdiction (specifically classified as motor-driven cycles), and that it did "not find it relevant to the question of safety standards' applicability that a particular vehicle, fully equipped to operate as a motor vehicle within the meaning of our Act, may also have the capability of operating in some other mode." Earlier that year, the agency had rejected arguments by Peugeot and Motobecane on behalf of their "mopeds" that vehicles which produce no more than 1.5 horsepower deserved a categorization other than as motor-driven cycles (motorcycles developing 5 horsepower or less), but it did amend the motorcycle lighting and braking standards to modify performance requirements for motor-driven cycles with a top speed of 30 mph or less, and to allow placement of the rear brake control on the left handlebar. Subsequently, on October 28, 1976, NHTSA informed Ohio Bikes, Inc. that a bicycle, even if used, became a newly manufactured motor vehicle when an engine was attached to it.

At first blush, it might appear that this line of interpretations should lead to a conclusion that the Yamaha is a "motor vehicle." However, we believe there is a significant difference between the Yamaha pedal assisted bicycle and motorized bicycles and mopeds. The propulsion systems of the latter vehicles enable them to operate on power without pedaling. However, the power assist of the Yamaha disengages when torque at the pedals is less than 11 pounds, which means that the system will not operate on its own, in the absence of muscular effort.

NHTSA has also stated in many prior interpretations that vehicles that will regularly be used on the public roads will not be considered "motor vehicles" for purposes of the Safety Act, if the vehicles have an abnormal body configuration that readily distinguishes them from other highway vehicles and a maximum speed of 20 mph or less. While the Yamaha has a maximum speed of 20 mph or less, its body configuration does not distinguish it from motorized bicycles and mopeds. However, the vehicles that NHTSA addressed under this line of interpretations operated solely on power.

The Yamaha does not easily fit into our previous analyses concerning whether particular vehicles are considered "motor vehicles." After carefully considering the question, we have concluded that, in light of the combination of a low maximum speed while operating on power (the power of the Yamaha disengages when speed is more than 15 mph) and the fact that power is only provided if the operator is providing muscular effort (by continuously pedalling), the Yamaha is not a "motor vehicle" under the Safety Act. We note that, even with power assist, the operation of the Yamaha is essentially the same as that of a bicycle, i.e., the operator must pedal under the same circumstances as a traditional bicylist and the speed of the Yamaha does not differ from the speed of traditional bicycles.

Since the Yamaha is not a "motor vehicle," it is not subject to the jurisdiction of this agency. Vehicles that are not motor vehicles are subject to the regulations of the Consumer Product Safety Commission, and you should consult the Commission for further information as to whether there are regulations that the Yamaha must meet.

Sincerely,

John Womack Acting Chief Counsel
