    • Customer service is worthless NEVER EVER DO BUSINESS WITH PNKKODW
NEVER EVER DO BUSINESS WITH PNKKODW. If you want any customer service, your screwed! If you want to try one of these kits buy it from a different seller. Update#7 After calling out the seller on the engine being less than 80cc they suddenly know the stroke and claimed the bore is 47mm and the stroke is 40mm. I find this laughable as even if it was that would calculate out to 69.4cc a full 10 cc short of the claimed 80cc engine. And they are defiantly willing to do nothing about it. Update#6 I began suspecting something was amiss as this engine did not seem to have the power of an 80cc engine. Pnkkodw would not answer what the bore and stroke is, so I disassembled and measured the bore and stroke at 47mm bore and 38mm stroke. This calculates out to 65.93cc’s. There is no justification for overstating the engine size by 14.06%. What an absolute waste of time and money. Update #5 Finally have the cables to complete my installation. After all the excuses, insinuating that I was lying, not responding for six days after recieving my complaint, the seller was to bothered to give me any part numbers and suggested I look up the parts myself because they wouldnt. They did commit to paying for the replacement cables and they did but not until after insulting me, and making unreasonable demands of me that were not possible. I do like the bike kit, at this point the only thing that doesn’t appear well built is the gas tank seal has begun to swell in the presents of gas after only having been exposed for about 8 days. Update #4: And the excuses have begun. First off, even though I repeatedly said I just want the parts that I paid for, they insisted on reimbursing me for the bicycle cables that I purchased. And they did. However they said they cant see my address so they cannot send the parts. So I sent them my PO Box number (that the kit was sent to) and now they can’t ship to My address. I asked for the part number to order the missing parts and they said to look it up myself. Good grief. 3rd update: I sent a photo of the reciept for sone lightweight bicycle cables to temporarily be able to test run the product. Customer service apologetically said they will refund the money I spent, but has as of yet to address the missing cables except to offer to reimburse me if I purchase them. (Again I do not trust this seller at this point). 2nd update: now that I’ve left this review, customer service has contacted me. They want a picture that I cannot take because I have already installed the kit and I was under no obligation to take this picture prior to installation. They want this picture because they say I could be lying, as these parts have never been missing before. Now they start with excuses: they claim the parts are not in any US warehouses, and I can order them from Amazon myself and they will reimburse (Like I have any trust in this seller🤦♂️) So, they want me to fix their mistake and trust them that they will reimburse now that they have made unreasonable demands to honor their warranty and suggested that I am Dishonest. These guys have the absolutely worst customer service that I have ever experienced. Update: A whole week has passed since the seller contacted me, and still nothing from them. Meanwhile summer months are quickly ticking away…… Original review: Received the kit and proceeded with the install, I was initially impressed with it. The product seems mostly well built. When I got to the install, everything went as expected until I got to the throttle and brake cables. They were not in the kit. So I contacted the seller and requested they send them. They replied with a request for a picture of everything that was received for verification. I emailed back that I had already installed everything with out the cables and couldn’t. That was three days ago and there has been no reply from them. I made the thing work with some bicycle cables from the bike shop until the seller replys and replaces the correct parts. I spent $15 and a couple of extra hours to install a “everything you need is in the box” kit that I shouldn’t have had to. Beyond the frustration of the missing cables it is fun and economical to ride! ... show more

    • Lots of troubleshooting, issues, problems, but once you get it working this thing is a beast.
Wow. Really amazed at the power of this engine. While it is all shipped with in my opinion cheap parts, I didn’t have too many issues with the engine itself. The main issues were the sprocket, exhaust, exhaust bolts, throttle, and the chain that came with the kit. Sprocket is insanely difficult to get on and even if you’re careful your spokes may bend. The chain seems sturdy but is cheaper than it looks. Mine completely broke for no reason mid ride. The exhaust had to be bent for my specific bike frame but not everyone will have to do that. Be ready with a MAP torch. It really didn’t matter in the end though, cause the exhaust bolts slowly stripped themselves and the exhaust fell off mid ride. Throttle broke day 1 before the bike even ran, but I took my front brake off and used that for the throttle instead. Ended up getting a new exhaust, sprocket, and throttle. Unrelated to the kit I’ve had to get new wheels, go to Home Depot like 20 times, and spend a lot of extra money to get this kit working on my bike, but once it works, it works, and works well. I recommend getting a smaller sprocket, I put a 26 tooth on and am getting between 35 and 40 mph at my top end. ... show more

    • 80cc bike kit motor
Good little engine for the price very easy to put it together and if you’re not sure what to do just go on YouTube there’s plenty of videos people talking about these motors The only problem I had with mine is when I put gas to the carburetor it was leaking fuel so what I did the tabs that the float touches you just want to bend them down just a little bit not too much and that fix the problem and the first time you try to start the bike it might take a few times because it’s a new motor and they’re not the best at cool starting I get a top speed on a flat surface around 25 to 26 miles an hour and I weigh 210 pounds would recommend to a friend would buy again it’s a lot of fun and make sure when you put this Motor together there’s a lot of vibration so I highly recommend red Lock tight and if you don’t have Lock tight try to find a old innertube and put it between the motor mounts to die down on the vibration a little bit ... show more

    • Would recommend.
Overall great for a beginner build. My build started as soon as I popped the clutch. All parts were included. Definitely buy loctite before you start this build. The hardware is on the cheaper side and will break if you over torque it.

    • Decent auto bike option, cheap parts
The bike worked pretty well until the chain tensioner fell apart and almost bucked me off since the chain flew off and messed my spokes up.

    • Great kit for the price
Review Image by 40 Something Mom 40 Something Mom
Overall it’s a pretty good kit. I had to bend the exhaust to get it to clear the petal crank. It is very important to tighten the chain tensioner well as it could get caught in the chain. Once I tuned the carb a bit, I could get the bike to a max of about 35 mph so it goes pretty good. You need to be knowledgeable about small engines as the instructions are terrible. ... show more
