What is the quietest motorized kit
Maybe this is a dumb question. I don't know much about 2-stroke or 4-stroke engines. I was looking at electric bikes and was amazed at the cost of them so I'm looking at these motorized kits. Does anyone know what the quietest kit on the market is? I'd like to get a 80cc. I want to go fast but I don't want to annoy the neighbors.

Re: What is the quietest motorized kit
hey mate. to be honest i dont think there is a quietest kit. they all are the same. just dont take out the baffel or modify the exhaust and they are not that loud.

Get a 4 stroke and muffle it down.

Re: What is the quietest motorized kit
For the regular riders (riding 3 - 4 times a week), how often do you find yourself filling the tank up on your bike?
Also, do you have a vendor that you recommend where I can get 4 -stroke? Is there a 80cc 4-stroke?

Re: What is the quietest motorized kit
They say you can get 150 miles per gallon. Not sure how accurate that is.
I was a daily rider and was so happy to be able to go two or three days on a couple of bucks. It really hit home when the customer in front of you just handed the attendant 80 bucks.
2 stroke is much louder but can be had for around $100, but a 4 stroke is much quieter and will last for years, why don't you have a look at the site sponsors on the left?

Re: What is the quietest motorized kit
I will mention that the better exhaust (chrome longer mufflers with the tube baffle) are MUCH quieter than the really crappy zinc coated short fat cans with the thin sheet metal "baffle" inside.

Re: What is the quietest motorized kit
Neither are any louder than a moped, and I have gone past many dogs and people in their yards without notice.
