Thread: Motorized Bicycles?

  1. #1

    Default Motorized Bicycles?

    I have read that a motorized bicycle is the legal equivalent of a bicycle and thus requires no lisence or plates. Is this true?

    I believe so, at least when they are limited to 80 cc or 1000 watts or less.

    It's probably going to be a guess by simply looking at it from distance. But most motors have it on the side stamped, or they could pull the VIN. Realistically if you weren't speeding, or acting a fool, they'd probably never know.

    Often times, the CC's are stamped, or cast into the base of the cylinder head of small engines like these.

    There is a federally mandated speed limit of 20 mph for non-vehicular motorized bikes. A 212 cc moped would be capable of much greater speeds and emissions would be significant.

    Federal regulations only affect the manufacture and first sale of bikes, not where, when, how, who and under what other conditions (age limits, licenses, insurance, registration etc.) they can be operated. The federal law has no “preemptive effect” over state laws. The state laws regulate the actual use . The federal agency regulating is the CPSC.

    So that means i go with Oklahoma's speed limit on bikes?

    The Oklahoma speed limit on motorized bikes is 35. Of course you could modify this later after purchase with a bigger cog. The following info was copies from WIKI:

    In the United States, federal law governing ICE motorized bicycles is subject to interpretative rulings by the National Highway Traffic Safety Administration (NHTSA) at the U.S. Department of Transportation. Under current NHTSA rules, a "motor-driven cycle" (a definition that includes a two-wheel vehicle such as a bicycle with an add-on ICE engine of five brake horsepower or less[25]) and a speed capability of more than 20 miles per hour lacks both a Vehicle Identification Number (VIN) and standard onroad safety equipment such as mirrors, turn signal lamps, side marker lamps, and stop lamps, then the vehicle shall not be considered a "motor vehicle" as defined by DOT/NHTSA regulations, but instead is defined as an off-road vehicle (since the lack of a VIN and on-road equipment indicates that a vehicle was not manufactured primarily for use on public roads.)[25] Such off-road vehicles are considered to be neither motor vehicles nor motorcycles, as those terms are defined under federal law.[25] Under present-day NHTSA rules, the final decision as to whether such federally defined off-road vehicles may be legally operated on public roads is determined by the laws of the state in which the vehicle is being operated.State and local laws[edit] (I added the bold)

    The legal status of an ICE motorized bicycle in the United States is presently determined by the laws of each state and/or local jurisdiction. Several states allow ICE motorbikes to be operated on roadways without registration, tax, or licensing in the same manner as bicycles, providing certain restrictions are observed.[26] Many state jurisdictions use limits on top speed and/or engine displacement to determine if ICE motorized bicycles require registration and licensing—sometimes as mopeds, sometimes as motorcycles.[27] Some states prohibit the use of motorbikes on multi-use recreational paths or high-speed, limited access roadways, while others require additional safety equipment for operation on public roads, such as wearing a helmet.[28] Many U.S. cities and other local jurisdictions may impose additional restrictions upon ICE motorized bicycles when operated on public streets and roadways.

    What do you mean by fitting a larger cog?

    What is the current Carbon Footprint Tax on a Moped?
    (do robot speeding cameras recognize them as violators?)

    just curious . . .
    that is all

    I was watching A Nova one night and they showed a pretty cool electric bicycle and the electric drag bike was unreal.

    Would it be nearly impossible for a Nova (regardless of horse or pedalpower) to get a robotic speeding ticket in a Spanish-speaking country?
    (on account of it no va?) (trans: don't go)

    Or is that eventuality almost certain to occur? =)

    All jesting aside . . . I just got back from hiking/brisk walking (not jogging) a path from here to there and back again.
    There were no sidewalks involved in my trek. And that was fine with me.
    If there had been sidewalks I would have had to watch out for rogue bicyclists invading sideWALKinan territory.
    If there had been motorized bicycles (mopeds) I might have been caught unawares.
    As it was, I was able to stop and take a leak, midway thru my journey, continue on to my destination, then worry only about crossing a motorvehicle pathway on the way back.

    I could have been run over by a "motorized bicycle" . . .
    but I wasn't, and therefore, their continued non existence is a good idea. =)

    (Didn't some guy write a book a long time ago about how rabbits view reality? Watership Down or something like that? Watership Downton Abbey? Or was it about squirrels? Magpies?)

    Yes a bigger cog will enable you to go faster. The downside is you are paying a price of less torque. You might need to pedal a little further in order to get up to speed quicker. Check out Craigslist or EBAY for motorized bikes. There used to be a place on Broadway and 10th across the street from Shlegals (sp?) that sold a reto styled bicycle manufactured by FELT that had a motor attached. The motor was a Ridley. Check out : Ridley Vintage Motorbikes : Vintage Motorized Bicycle Kits

    Check out the history on WHIZZERS, a modified Schwinn from the 40's to 60's and later relaunched, though I think they are currently in hiatus.

    Neato. Ridley is an OKC company. I didn't know they had branched out into retro bikes. I have a bike frame I was going to add a motor and mod into something similar but I'm not making any progress on it. Never decided if I really wanted to put in the effort to go retro or make an electric.
