80cc Motorized Bicycle NJ - considered a moped?

Hi y’all. Help! What’s the deal with gas powered bicycles like this one? Is it considered a moped?

I know that you don’t have to register e-bikes, but is this different because it’s gas and goes almost 40 mph?

AFAIK, it's completely "illegal" by NJ laws, and most states in NE

It has to be 49cc to be considered a moped

Thank you!!

Re: 80cc Motorized Bicycle NJ - considered a moped?

Man mopeds are sketch enough. But at least there is usually a bit of frame protecting you from the engine and any possible detonation type failures. These would just munch up your legs...

I rode one of these last weekend. Mounted to some really shitty old bicycle. Its a death trap. Dont recommend one if you intend to stay alive

Re: 80cc Motorized Bicycle NJ - considered a moped?

A 40mph bike with the absolute worst caliper brakes on painted rims isn't the best combination.

I would avoid, you would be better served by an e-bike.

They are very popular here in Central NY… personally, I don’t like them.

But, it does get their feet wet. So to speak

Re: 80cc Motorized Bicycle NJ - considered a moped?

Those are so bad haha, I mean they can be made ok, but this isn't there.

Legally they're a weird gray area, you can usually get away with it being a bicycle. It's not a moped really anywhere, and if they wanted to dig into the laws it's probably an off road only kinda deal, but in practice most cops are gonna ignore it as a bicycle

Re: 80cc Motorized Bicycle NJ - considered a moped?

^ Not in MN, the cops here DESPISE those things for some reason, electric bikes are totally fine, mopeds are cool, but show up on one of those and they will make you shut down the engine and pedal it away if you are lucky enough they don't order it impounded. I know 2 buys who built them and the cops hounded them into selling them or one guy just took the engine off as it was on a pretty decent bike.

I rode one daily for 3 years, I got pulled over once at night and cop just asked me what it was and told me to put some lights on it. I live in south jersey btw. I would always kill the engine and pedal if I seen cops. Best advice I can give you is find a way to run it with out that chain tensioner. I did that by going with a 36 or 34 tooth rear sproket. And get a chain tool and shorten the chain. Alot of people do away with that and the fenders for safety issues.

My two cents... I'll talk about the situation here in Brazil.

Motorized bicycles here are considered "mopeds", as well as electric bicycles and electric scooters, because they have a twist throttle, like any moped or motorcycle. Many cops don't care, but there are always that shitty bully cops that will arrange any reason to impound your ride and give you a fine.

The majority of motorized bicycles has no bicycle pedals, being switched for motorcycle pedals, for more commodity. That happens in most mopeds here, as well.

Despite the law here consider any vehicle over 50cc as a "motorcycle", the reality is that the cops here don't know ro differentiate a 50cc engine from an 80cc engine. So, you talk to the cops that your bicycle has 50cc, even if it has 80cc, or even 100cc.

Re: 80cc Motorized Bicycle NJ - considered a moped?

I had one of these here in Massachusetts for awhile, it needed to be registered as a moped with a special ‘bicycle converted to a moped’ form. Overall I didn’t really like the bike, mine was done up on a newer 29” Mongoose mountain bike so the bike felt very stable at full throttle with the 80cc engine but there was massive vibration with the motor bolted directly to the frame without rubber mounts and the tiny muffler was super loud. I ended up taking the motor off and selling the bike for more than I paid for it during the bicycle shortage at the beginning of the pandemic…took that money and dumped it into my Sachs and I’m much happier now!

Re: 80cc Motorized Bicycle NJ - considered a moped?

I have built one and even threw one of those motors on an actual moped. (long story)

but theyre trash and unreliable.

in GA it was totally legal grayzone. you needed a license technically to ride a moped or a scooter but those were like whatever, so it was always DUI folks lost their license riding em. The one I built would come up for sale about every year. somehow it was still running but once the last buyer got their license they were back in a car and it was back for sale to the next DUI offender.

Its good advice to ditch the chain tensioner, or weld it on. otherwise it's gonna get yanked into the back wheel and fuck all your shit up.

but it's far better advice to just avoid this thing entirely.
