Quite a bit of the hardware came in relatively good quality with only the rag joint hardware needing an upgrade. The speedometer broke immediately on installation. I'm sure on a specific bike it may work great but as for a huffy Cranbrook it won't fit at least without modification and even then like I said it broke after the first two wheel spins. You may have better luck than me. Other than that it's been a reliable little kit that I'm also able to have fun with. It's great on gas getting about 30 miles out the stock tank. I weight 210 pounds with 2 moderate hills so in my book it does well. Break in went without issue. There's not much to say bad honestly I'm pretty happy with my kit and I will be buying another when I start my next project. Please note I have been dailying this motor kit on my bike and have put about 250 miles on it with no major failure other then the chain falling off a few times.It has been through rain,light snow and shine and has done well as far as affordable transportation/ fun goes. I will update with photos of my bike when the weather is a bit nicer so I can give you guys quality photos.

I had to rewrite this review I gave it a three star first. But this engine only lasted about 6 mi before it blew the head. The carburetor and the coil magneto and magnet all had to be replaced before the engine would even start so all the factory parts were garbage. Absolutely do not purchase this engine kit for this type of engine it is garbage. So far I've got more in extra parts then I paid for the entire engine kit and now I have officially announced that this product is a fraud!

I recently installed the Afranti 80cc Bicycle Motor Kit on my 26" bike, and I’m extremely impressed with the performance! The installation process was straightforward (just make sure to follow the instructions carefully), and once it was set up, the motor runs smoothly. The 2-stroke petrol engine provides plenty of power, and I can easily cruise at higher speeds without breaking a sweat. It fits perfectly on my V-frame, and I love how the motorized kit transforms my regular bike into a super-efficient mode of transportation. It’s surprisingly quiet for its size, and I’ve been getting great mileage on a single tank. Overall, it’s a fun and cost-effective way to upgrade your bike for commuting or leisure rides. Highly recommend it to anyone looking to add some speed to their cycling!

I bought this knowing that it wasn't going to last from watching the youtube videos that you all have probably watched already. The bike worked great, but the threadlock that I also got never took on this bike. I don't know if its something with the metal, but the bike ended up falling apart mid ride, and I had to walk it home. It has stayed in the shed since. Very cool project, and I would recommend if your looking for a cool engineering project to do over a weekend!!

Got it running for 20min. Wouldn't start again. Not worth it go electric Wait till you try putting that sprocket on lol and in the picture they don't have a chain tensioner yet the kit comes with one. Tensioner caused issues. You'll have to cut the chain down. Better have a huge pile of tools because that is what it's going to take to put together and then you'll find out I was waste of time. Just do have to take it off and convert to a electric hub easy quite light.
