80cc Black Bicycle Motor Kit

Took me about 3 hours to put all this on my mountain bike. The instructions left a lot of key detail out so I used You tube to find out how to put the carb linkage together and find out what the white wire was for. Apparently it's for a light. Headlight, run indicator light? Who knows. I'm going to use it to charge a battery like a more legit motorcycle. It wasn't too complicated to put together, just took some modifications since my bike has a thicker frame than this is intended for and top bar deralure cables and brake cable, so I had to make a spacer for the gas tank to fit on. The clutch lever has a catch so you can still use the bike without motor power. Drop the clutch and it starts right up. Break in period I'm running 16:1 and it get's up to about 25 MPH. Once it breaks in it can easily get up to 35. 40 if you replace that dinky little air cleaner with maybe a aftermarket breather element from Autozone (those one's that look like a tinny cold air intake filter). It looks menacing and a blast to ride. Break it in and it will last. looks to be a well built little motor. I'd recommend this kit to anyone who owns tools and some mechanical know how. P.S. It's a Chinese kit so obviously get your metric tools ready.

The kit came in pretty fast no complaints there. When I opened the box I took out all the parts and the instructions. The instructions are pretty horrible and a few of the steps will not apply to this motor kit. I started running into problems when trying to assemble the clutch. The manual says the kit comes with a clutch stop that is supposed to keep the the clutch cable under tension but the clutch stop pictured in the manual is not what you need to find. So after about about 30 minutes of searching through empty boxes thinking I've been had. I found a tiny screw stuck in a metal bracket that fit into a hole on top of the clutch arm. If you have a big framed bike you might have to buy special brackets to get the motor to fit to your bike and there are no spare parts with the kit. The best advice I can give to people that buy this kit and have not put one together is to use youtube. There are twenty or so videos on installation and trouble shooting. I'm pretty happy with the way the bike works. I get speeds of 35mph and about 100 miles to the gallon.

Well the motor runs great wen it does run I'm still in the break in stage but the bike lately is having problems when I'm using the throttle I'll be going smooth then by its self it starts to sound like its stalling and it acts like it wants to quit then go it does it about 4 times in a row within half a minute time if I hold the clutch in and rev it a Lil it fixes its self for about 100 feet then does it again it only happens some times also the vibration makes the choke lever go up by itself and had to modifi a lot but over all once we find out the problem it will run great

The motor got here way befor expected but that's about the only good part about it 2 days into the break in period a gasket in the fuel petcock got eaten away by the fuel nd clogged it so it wouldn't run I got it Un clogged nd it seems to be running ok for now but have only road it like twice since then it was a nightmare to assemble because the instructions were terrible nd when I emailed the seller to find out the fuel ratio they told me it was 50 to 1 synthetic 2 stroke oil then I found in the instructions that for the break in period it is 16 to 1 none synthetic after that it goes to 20 to 1 synthetic so they really didn't know what they were talking about when the motor is cold it is a real pain to get started you have to play with the choke while trying to ride the bike witch is really jerky at first I would recommend spending the extra money and find a good motor kit from a site that actually knows what their talking about

Works awesome. Took me 8 hours to put together. I'm 6'2 280 lbs and it hauls me. Up hill I have to peddle but still cruse right along. For this price, can't go wrong. I bought an $88.00 beach cruiser from Walmart slapped this together in one night 8 hours. Worst part was putting the sprocket on the rim. Soon I'm gonna get another to put on a mini bobber project I have. Why not, looks cooler than a weed eater engine and not as bulkie as a briggs. Cool,fun and powerful

I'm still trying to assemble it. The instructions that came with it were not detailed enough and even someone with mechanical knowledge could get hung up. Good news though, You tube from Power King Motorized Bicycle kits provides a very detailed step-by-step instruction guide video that walks any non -mechanical person through with ease. I was happy about that, but the motor had the wrong clutch base screw which stopped me in my tracks. Nothing is perfect although when you pay for something from a reputable online company you expect better. Sorry I did not have more positive things to say, but you asked me, and I would not have even given it a star at all, but you have to check a star in order to write this review. So for the sake of wasted time I give this product no stars and as for the performance of the motor I can't even say.

Everything except the chain was super easy. Also the intrustions were hard to follow. And make sure the chain is aligned right because it will snap into ity bity pieces

I am very happy with my order it arrived on time and it was not hard to put together.I would recommend this co if someone wants a bicycle motor kit.
