Need Help

Prettyboy · #1 08-31-2009, 11:08 AM

Hi I am new to this forum and motorized bikes in general and I need help picking a motor that's right for my bike and needs.

I need a motor that is in the $100-$150 price range.
It also needs to be able to comply with New Jersey state laws which I believe the CC has to be under 50.
I also want the quietest motor possible and I will be able to ride my bike with it's normal gears when the engine isn't in use.
I know that a 4 stroke engine will probably be quieter but those are up in the at least $300 range which I don't want to spend.

If anyone could help me that would be great because I'm really interested in making my bike motorized, quiet and to it's full potential. Thanks

Haha this website has some sweet smilies

I can't post a picture of my bike but the triangular frame dimensions are about 17" by 19" by 21"

Can't vouch for any of the sellers there but with your budget you can always check ebay for the 49cc kits.

Yes I was thinking about that and the exhaust on this model

LTD 49CC BICYCLE GAS MOTOR ENGINE KIT MOTORIZED BIKE 2L - eBay (item 290342667282 end time Sep-22-09 08:29:48 PDT)

says "hush" exhaust and I'm mostly worried about the loudness of my bike.

All the mufflers in the kits are the same so it's gonna sound pretty much like a weed wacker.

well are there any aftermarket mufflers or good kits that are really silent?

Amazon.com: Walker Exhaust 22229 Quiet-Flow Muffler: Automotive

would this help in any way and would it fit the muffler from ebay?

mmm... I think you'll find the std muffler pretty quiet in the scheme of things ... i reckon the best way to start the job of quieting the engine down further would be to add some kind of damping to the case covers each side ... but particularly the gearbox cover

also damp down head & barrel fin resonance with some old fanbelt rubber or somesuch...

then you could work out a way to tackle intake noise

the exhaust silencing ain't bad right out of the box, in my view; ...

Are you saying that kit from Ebay is pretty silent? And how would get go about damping all this stuff i dont know what that is or where any of those parts cause I'm a noob at motorized bikes.
