IMAYCC Bike Motor Kit 100cc Motorized Bike Kit 2 Stroke Gas Bicycle Engine Conversion Kit Fit for 26-28" Bikes (100CC Black)

Getting everything on my bike wasn't too hard, but you'll need a lot of mechanical knowledge. I ended up having to replace some parts either because they were faulty or didn't work properly. The carburator jet is too rich which caused 4 stroking and fouled spark plugs. I bought a new carb and jets, which seems to have improved performance. The expansion chamber I bought also helps.The major issues I have are with the gas tank and engine mount. At some point while I was riding, the front engine mount and studs fell out, and I didn't notice until I got back home. I had to make my own front mount with parts I bought at the hardware store. The gas tank leaks all over the engine and onto the ground when I fill it above the seam. I have yet to find a solution but the last thing I want is my whole bike to burst into flames.EDIT:After writing this review, the seller reached out to me so solve the issues. I sent the pictures of the broken parts and requested replacement parts. They told me to order a new kit so that I would get my parts faster and then they would refund me. I was a bit skeptical at first because I didn't know if it was legit, but it looks like I've been refunded in my Amazon account. Just waiting for it to deposit into my bank account. Overall, really good customer service, reach out if you're having problems.

There are numerous problems with the kit itself. Off the top of my head: the carbeurtor has a fuel leak right out of the package. The wires don't fit into the connectors. The chain it comes with is terrible. The sprocket it comes with is made of cheap material. The two pieces of rubber that are for the sprocket are terrible. The instructions are vague and blatantly wrong sometimes. The spark plug doesn't spark. This is not worth it's price. The engine blatantly doesn't work. Save your money and just buy an ebike/motorcycle/minibike with less building requried.

The kit comes with everything. The you’ll tools and hardware. In my case the frame of my bike didn’t really want to cooperate and I’ve had to do several modifications so the motor would fit. I had to take the chain guard off so the motor would come down as far as it could. I then manufactured a homemade spacer for the bottom of the motor mount out of the heel of a boot. Seems to be holding up fine.The next thing is the carburetor doesn’t seem to be wanting to stay securely in place. I’ve tightened it about as much as I can without feeling like something is going to brake. Still loose.Next the muffler can be modified by cutting the baffles out. Gives you a little more speed. I tried to take the nut loose off the bottom and it broke off. I think the hurdle can be crossed though. With a little modification.Lastly the sprocket that comes with this kit is difficult to install on coaster brake rims. I recommend putting the extra money into a hub adapter sprocket that has a hole big enough to allow for the brake arm. Or one that requires little grinding to fit. You’ll have to put it in a vise and bend the arm so it’ll clear the sprocket.Overall the kit seems pretty good. I like how it comes with all the tools; except for a drill. Good value for money. However, it does seem slightly cheaply made. You can definitely tell these are mass produced and the customer (you) is quality control.Some pieces of valuable knowledge I’ve gained from building a few of these….Use thread locker on exhaust bolts! Really, use thread locker anywhere you can, because as you ride things loosen especially during brake in period. Keep a few wrenches handy as you ride.Before you go ride, check your bike. Make sure nothing is loose. Check tire pressure and wear a helmet. Going through a few check points will help you have a better ride experience.Always check for loose parts. always check for loose parts. Always check for loose parts.

Thing is perfect let’s face it it will never be faster then an electric but the sound is phenomenal The only thing I’d say. Is have patience with it and you might. Want a new chain tensioner from that it’s good you will be needing a ratchet or wrenches on the side becouse the ones they send are awful and run it a little slow at the start it is a fairly easy set up took me about 4 days to put on videos do help but some leave you in the dark the build is good and it gose on it’s durable and is a good value compared to an e bike it’s not a plug and play but loud and fun it fits good on a v frame and like I said is durable mixing gas and slapping ass you feel me

Worked great. Must be mechanically inclined

This engine performs really good. Ranging from speed, fuel efficiency and reliability. Topping out at around 30-35 mph for me. I get around almost 50 miles per tank which isn’t bad at all for such a small engine. It’s a reliable engine as parts are cheap or expensive to fix but it differs. Ranging from 10-100 dollars per part/set.A couple down side parts about this engine is how it maintains. I’ve had this engine for about a month and it was slowly dying on me until it gave up. Parts from inside the engine and outside were breaking off. While also destroying the inside of the engine. Parts are cheap but with all of the money I spent on parts. I could have gotten me a brand new engine kit/set.Now these are Chinese motors and I wasn’t expending alot from it. But surviving only a month and it broke on me already? That’s pretty bad. I’m giving this product a 3/5. A three for the fuel efficiency, speed and reliability. Removing two stars because of how cheap the engine is made of, and how easy parts can break off. Also because of the engine dying on me.This is my honest review. Thank you for reading. I hope this helps you understand this product and thinks about buying this.
