Motorized Bicycle Law Reforms Proposed
Posted on January 20th, 2013 2 commentsThe topic of motorized bicycles (henceforth referred to as MBs) always seems to be controversial.
Regardless, the current set of definitions and laws seem to have been drafted in such a way that has led to some interpretations with, in my opinion, absurd results.
There are a set of proposals that seek to amend/clarify MBs positions at kcsbikes.com, and while I don’t necessarily support the specific proposals, but i do think some “reform” of the MB law is definitely needed!
Here are some thoughts off the top of my head about possible reforms:- Incorporate definitions congruent with Federal / CPSC definitions of “low-speed electric bicycles” (750W), the current Arizona definition oddly doesn’t mention electric power rating.
- I can’t imagine the cc limit would ever get raised
- The mph business should be changed to an *equipment* limitation and not an operating limitation; see other state’s laws on the topic e.g. CA language CVC 406b, something to the effect of the motor “is capable of propelling the device at a maximum speed of not more than xx miles per hour on level ground”. There should be no prohibition on operating speed (the usual speed laws, that apply to everybody, of course apply to MBs, as they do to bicyclists and no explicit reference is needed or desirable)
- somehow cities/localities should try be prevented from trying to (mis)apply local “play vehicle” ordinances to MBs
- While we’re at it, a good clarification would be to state explicitly that the definition of moped that the speed mentioned is an equipment definition; some have argued this is an operational restriction, though I would disagree. I.e. 28-101(31) “Moped” means a bicycle that is equipped with a helper motor if the vehicle has a maximum piston displacement of fifty cubic centimeters or less, a brake horsepower of one and one-half or less CAPABLE OF PROPELLING AT a maximum speed of twenty-five miles per hour or less on a flat surface with less than a one per cent grade.
Apparently some places (the prime example i know of is Tucson), the police/city currently consider MBs operated at 20 or above to be mopeds (or possibly motorcycles); and that this leads to a cascade of potential criminal charges and large fines including 1) driving without a drivers license (if applicable), 2) violation of financial responsibility / no insurance, and 3) driving without registration.
It’s my theory/understanding that it’s impossible to get a MB registered with AZ(?), and furthermore, it’s impossible to purchase liability insurance for a MB. If this is the case — i would think you could get some more libertarian-minded legislators (there are plenty of them) interested in what seems to be a government-built Catch-22.
Insurance / Financial Responsibility
Is required for “motor vehicles” by 28-4135: “Motor vehicle financial responsibility requirement… A motor vehicle that is operated on a highway in this state…”. As things turn out, bicycles are not vehicles (28-101(57) ) ; and both mopeds (28-101(31) ” ‘Moped’ means a bicycle that is equipped…”) and motorized bicycles ( 28-2516C ” ‘motorized ….bicycle’ means a bicycle equipped…” ) are defined as types of bicycles, and as such neither of them are vehicles.
Therefore it would appear no insurance is required for bicycles, motorized bicycles, or mopeds. Insurance IS required, however, for motor driven cycles (usually called “motor scooters”; e.g. vespa), and motorcycles. Note that this conflicts with what Arizona MVD says in FAQ ”42) What are the differences….? Mopeds – vehicle insurnce is required”.????
Driver’s license
Bicycles require no operating license, see bicycle-license. I found it interesting to note that nowhere, in statute, does it say a license is or isn’t required.
Motorized bicycles state explicitly in their defining statute 28-2516A5 state ”A driver license is not required to operate”.
Mopeds: 28-2513 ”7. Any class of driver license is valid for operating a moped” (so I guess that moots the point about is a drivers license is required by virtue of whether or not a moped is a motor vehicle?)
Motor-driven and motorcycles clearly require a class M endorsed driver’s license. In the first place, they are both motor vehicles, and thus require a license per the general motor vehicle license requirement, 28-3151 ” a person shall not drive a motor vehicle … without a valid driver license and proper endorsement”. The business about endorsements is covered in 28-3101 and 28-3103A
Some Deep Background
Much of the impetus for the 2006 law, both state and Tuscon’s was due to the efforts of Spooky Tooth Cycles; a retailer of motorized bicycles. There is a trove of, albeit anecdotal, info on their forum. I also looked up the House and Senate Transportation committee meetings; they were pretty uneventful, according to the minutes… the video is available, but I didn’t watch it.

I am in my 3rd year building motorized bicycles for a living and riding them for my own transportation needs so I consider myself a pretty well informed source on them.
Ed and I differ somewhat on what should be allowed for a bicycle with motor assist and what is required to operate them, but we both agree the rules are vague.
I do feel some prudent limits need be in place to keep idiots from killing themselves, I also feel that anyone than can responsibly ride a bicycle on the road should be able to keep up with even the best athletes with as much motor assist as that may take.
In short, the ability to ride along side a doped up Lance Armstrong on his 5 pound racing bike sitting up comfortably on my 50 pound solid bicycle.
Motor assisted bicycles are not for recreation, they are primarily used for feasible low cost independent personal transportation needs.
Limiting assist size by ‘Capable Power’ is not the way to go. It is so ambiguous, difficult to establish without specialized equipment, and it does not take into account the size and weight of either the bike or the rider.
For example any athlete could compete with Lance with just a 48cc 1.95HP assist on the same bike but the regular non-athletic people that need an assist don’t ride $10,000 bicycles and not able to pedal around the block without getting winded but still need to get to and from work in a timely fashion on a tight budget and that is where motor assisted bicycles come in.
The power required to move a large 250+ pound man on a large heavy Beach Cruiser style bicycle at even 20MPH is much greater than that of a fit athlete on a race bike.
My contention for a motor size limit is yes, there needs to be a number to keep the idiots that might want to try to put a Harley motor on a bicycle in check the bottom line is in the motor assist world the 66cc 2-stroke 2.75HP engine is the defacto standard best power plant for efficiency and cost.
30MPH max speed is a reasonable, safe and actually practical speed for those that have a 10-20 mile round trip work commute or even just a cheap green and fun way for those little neighborhood store runs.
Please support this, there are a lot of able workers in this state that need help and if practical less cars on the road or taking up parking spaces.
