You aren't letting it warm up before charging down the road with that tiny engine.
Or the spark plug needs replacing / cleaning / gapping.

To work on an ET2 engine, there in no need to remove the body parts on a 2005 ET2 Vespa 50cc, as most maintenance tasks it can be performed without disassembling the body parts.
moved you vespa, no Shanghia here.
you wired it wrong, and not only that fuses left out of cicuits.
fuel + wires burning is never safe to mix
so find real help in a real shop. for scooters.

Question moved from Cars and Trucks to an e-bike category.
The bike carries a lot of weight in batteries. It would be rude to ask what you weight, but it could seriously affect performance especially uphill. The bike has 4 x 12 volt batteries making it run on 48 volts. The standard batteries are rated at 8 amps. To get more pulling power, you can get an uprated 12 amp battery for more power and longer range. The manual states the batteries have a life of about 400-500 charges. I think this is optimistic.
Press the lid down as you try to unlock it. The jacket is probably causing the lock to bind.
Please add 'make model (what it is)' to all questions. I moved from the Seat category, they are a Spanish car manufacturer. You may be talking about a mobility scooter, but Vespa has a place in my heart from the late 1960s.
moved you out of computers, it is not.
no eBike stated, maker nor model, wow, must we work blind too.? sure in a text box blind.
no question stated, only some vague words.
you do know it's battery powered, right and if not kept charged it will not GO.
and if charged too little , range is less.
!
and all batteries have short lives, per this.
and the range will decrease as you drive further, to far.
the battery maker even has chart to learn this.
as you stress any battery like this , the total range reduces.
Just like your CELL phone same thing.
That is great price for the 2008.......The money You will save, by buying the 2008 will easily cover any problems that may arise......Vespas have a very high resale value.....I recommend an authorized Vespa dealer to perform any and all sevices to maintain the resale value.........
The brake lever also activates the brake light, their may be a break or short in that wire ( easiest check) and second guess would be the wire which activates the starter,
The float pushes a needle that then stops the fuel flow make sure its not the needle thats sticking or what ever pushes on the needle is not sticking ! But if you are sure it is the float that is sticking a fine sand paper (320 ) can be used around the sides of the float to smooth down any rough bits .
it's not a bug - it's a feature....some people would say...
- actually it happened on mine too after some time when it was new on both brake levers, that means it cannot be a short or something.
but, after some time I got used to it and even got to like it like that.
A weak spark could cause this as when the throttle is opened the cylinder pressure rises sharply, the atmosphere inside becomes very dense and a much higher voltage is needed to make a spark.
If it is fuel starvation then partially applying the cold start, choke or strangler should alleviate the problem somewhat; signalling you missed something when checking the fuel system.
The clear one connects to the battery vent connection and vents under the vehicle. The other two likely are overflow hoses coming from the carburetor to prevent engine flooding if the float valve is not sealing well causing gasoline level to get too high. They are open to the air.
