Brand new to MB's and need some info..

conradcliff · #1 10-10-2008, 09:51 AM

Hey guys, I pretty much just started looking into these motorized bicycles about 2 hours ago and they have definitely peaked my curiosity...but here's the thing, it seems like the only way I'm really able to beat the price curve is by getting one of these extremely cheap kits because otherwise I'm paying nearly as much as I would on a decent used moped.

What do you guys think? Are these cheapo kits any good? I really haven't done a ton of research yet so maybe I'm way off..also, MB's do seem to have the advantage of higher fuel efficiency, customization/parts availability and of course...you guys

What kits do you guys recommend?

Anyway, hope I posted this in the right spot, and thanks a ton for any help!

dont get me wrong i love my cheap-o china engine but some the the parts it comes with are "cheap-o" and also you have to consider that , like mine , it will run fine for hundres of miles no problems then some weeks you want to beat it like the red headded step child you never had. all in all i love it to death and the hundreds its saved me at the pump. and there are a lot of top notch guys here that are always willing to help. hope this prepares you for which ever engine you decide on

Hey, thanks for the quick reply! Yeah, that does help me..I think I should add two more questions to my inquiry:

How many miles can someone expect out of the cheap-o china engines?

and (the big question I forgot to put in the original post)

What engines/kits do you guys recommend?

Thanks again for any help, it's truly appreciated!

I have a china engine kit and some parts are definitely cheap junk for example the chain tensioner. That tensioner was the first thing to go. Now i have an idler sprocket as a tensioner. The cables included must be lubricated otherwise you will break that clutch lever in no time. My kit has over 800 miles on it now since August. If you do buy a kit dont by the roller bearing china engines since many have had issues with the bearings being destroyed. Good luck on whatever you decide.

pretty much all the engines are the same in quality . so cheaper the better so you can upgrade the parts that need it ,like the drive chain that comes with it,

and ive seen members post that have got over 2000 miles im sure as long as you dont abuse it you can get more

i read somewere that an older guy got 12,000 mile out of his ht. i have a roller bearing engine and it runs fine(with some mods) and a bushing engine that also runs fine.

I have a cheap china kit and it runs fine. I don't ride it much since i started to build alternate engine bikes. I have one 31cc ryobi bike that would cost a little over fifty bucks to build. A 33cc chainsaw bike that cost about 75 to build total. a 42cc chainsaw bike that cost about 75 to build.

I ride those mostly because they are more fun. Nonetheless for a first bike you can't beat the china bike. You will learn a heck of a lot bout motors lol.

Thanks a ton for the replies everybody!

But I have just a couple of questions...

So if I do go with a china engine I should get an after market idler sprocket as a tensioner. Where did you buy your kit and this tensioner from...a link would be awesome! Plus, How do I know if it is a roller bearing engine? What are the different types?

europorsche seems to think that the roller bearing china engines are low quality, do you disagree with this?

Sorry, but being a newbie I don't really know what "ht" stands for..could you clarify?

Thanks again for all of your help!

Wow!

Those are incredibly cheap! I would totally be willing to get into the 42cc class for less than $100 bucks! Is there a good starting point for learning how to build one? How fast is that 42cc engine capable of propelling a person. Are these used engine that you find on ebay or something and what brand are they?

Sorry for all the questions but that just sounds awesome!

ht is a happy time or china engine or as you put it a "cheapo kit".
