Less Cool...
MN HP may decide it's a motor vehicle and you don't have a licence.
so you get a ticket, a moving violation, unregistered vehicle,
and you unlicensed to run it..

I'll let you all know how this turns out. 1300W FRONT hub motor on a custom cruiser. Had to fabricate a special torque arm for the springer fork to handle that power being sent to the front wheel. Batteries will be located in the saddle bags on the rear rack, all wiring run through the frame...

About the only reason that I see for petrol powered bikes is to have extended range. I gave it some serious consideration before building my touring trike using solar panels. Going petrol is cheaper; but it introduces factors, such as noise, that I didn't want to deal with.
As was mentioned above, in many states a petrol kit requires a vehicle license, and all that goes with that.
I really think about steam a lot, I am just too worried about leaks and accidents. Steam power can be extremely dangerous. Frankly, in comparison to steam, petrol is quite safe.
The only way I can see going steam is to put it on a trailer. I know I keep returning to this point, but steam is just too dangerous.
As it stands, my fun bike is a conventional pushbike, my commuter is an e-bike. I am considering rebuilding my solar trike for more summer touring. Petrol, and as much as I hate to dismiss steam, isn't in any plan.

Got turned onto the Bafang motors after years of speculation over powered bikes in general. A coworker let me borrow his Bafang 750W equipped folder for a week in 2016 and I was more than impressed with the speed and range.
I ended up getting a BBS02 and a BBSHD for both an old cyclocross bike I picked up from a yard sale and my Catrike Expedition.
They do get addicting and now I try to go as many places with pedal only and gym trips. I save the motor use for riding on the main roads out here.

Glad I found this thread. I thought there was a forum for (gasoline) motorized bikes...I guess not.
There is: motoredbikes

Has anyone built a hybrid bike with a gas engine on rear tire and electric on front that can be switched over to the gas engine when you run out of power for long distance trips?

I think a springer fork is a good solid idea!

My grandmother's solex would be my choice. 70km on 2 liter of gasoline. Can't beat that. Not even one horsepower so you get a workout to if your going uphill.

No.
Unless, by "electric" you mean that it has a generator?!!😂

The motorized kit that some have referred to is not ideal.
It is 2 stroke. A 4 stroke would be much better.
It is very noisy. Anyone putting one on a bike should look for a better exhaust, probably from a motorbike.
It has no gears, and is like riding a motorbike in 2nd gear all the time. To go at a decent speed, the motor needs to rev hard, which no doubt shortens the engine life. It would be ideal to have a smaller rear sprocket, so it can go faster without revving too hard. Then the rider should start with pedal power only, to avoid killing the clutch. The motor is then started by dropping the clutch.

You can clearly see the hub motor in the back wheel.
Four stroke wouldn't be better. It would probably be quieter, but a four stroke requires at minimum a valvetrain and oil circulation, and has less potential to make power. It'd be an increase in expense and complication.
The real problem of these 2 stroke kits is that the quality control is poor. The design heritage is very old, directly descended from a product of the kharkov bike factory in USSR, the only thing the chinese have done to it is switch from rotary port to piston port to try and save some money, then increase from 45 to 66cc using a jug with absolutely terrible ports. The new bigger piston has made it unbalanced, so the revs are limited by it vibrating itself to death, which is then helped along by the cheese grade bolts and almost totally wrong ignition timing. Hell, they don't even clean casting flash off and just tell you to run a couple tanks at 16:1 oil ratio...
It's possible with knowledge and time to get them to perform much better, not even really spending any money beyond grinding stones for your dremel and a new CDI. Correct the flaws and they have a nice wide power band and a lot of low end torque without much vibration.
But since these china motors got popular in america amongst the illiterate DUI brigade and intellectually subnormal teenagers, trying to find good info on them has become very difficult for beginners. The market has been flooded with people selling purple anodized cylinder heads, banana shaped exhaust pipes and god knows what else. The only performance improvement of any of that crap offers is weight saving your wallet.

The solex engine is a easy engine to put on a bike as well. Maybe a little low on power but there are ways to give them some more. And there not that noisy. And parts are really easy to get.
To start them start biking and drop the engine on the front wheel and keep going until it starts. And off you go.

AMAZON ACCESSORY BATTERY KIT
Anything powered over 10 miles an hour with combustion and or
chemicals added needs to be registered for safety reasons. Battery
acid. It caught on fire accidentally. I'm delivering food and switch
batteries and fuel up accordingly.

Gas engine kits should be outlawed, at least all but a few bikes.
I keep seeing the cheapest of the cheap with 80cc engines on them.
What gives? Why would someone put a fellow human on what is a death trap by any other name?
Sure that coaster brake or crappy rim brake might slow you down from 35 to 40mph a few times, but what then?
Once that brake gets hot there goes your stopping power.
Not to mention the stress dynamics it (frame+forks) was engineered for are multiplied by a factor.

)I'm faster on my bicycles, even the old single speed Huffy "Key Largo" "Beach Cruiser" I have, I can average 15mph on level ground with no tail wind. Again, no motor or engine on any of my bikes or trikes.
