Sange 2 Stroke Pedal Cycle Petrol Gas Motor Conversion Kit Air Cooling Motorized Engine Kit for Motorized Bike (110cc,Silver)

I was on the fence about ordering this because of reviews. But after getting it and putting it on my bike i realize the bad reviews are probably from people that are not mechanically inclined. You will have to most likely modify a few things so if you dont know how to use a drill for holes or an angle grinder for chopping and shortening then youre screwed and will probably write a bad review. After i put this engine on i couldnt stop riding it, it is so much fun most likely will be getting upgrades for it or saving for a 4 stroke. But overall great product definitely recommend it to anyone that is relatively smart when it comes to this sort of thing.

Engine runs good probably going to go to a smaller main jet #68 it's getting too much gas at full throttle and bogs down with the stock jet which is #70.

The packaging and first appearance was excellent but upon closer inspection and teardown if the motor I found so many things wrong with it!!! The bottom of the cylinder sleeve is cracked and missing a big chunk, the port work is hideous!!! The intake and exhaust surfaces were damaged and cast horribly to the point that there's no way they would seal correctly... Piston was installed backwards and would probably cause motor to seize as well as break the piston rings. The hardware was finger tight throughout entire motor. The clutch bevel gear had no grease nor did the the clutch bucking bar and ball bearing. Also it was listed as an Amazon prime listing and it was shipped snail mail via FedEx and showed up several days later than expected Also listed as 100cc it's closer to 70cc by my measurements and calculations If this thing even runs even after cleaning up the ports and crappy gasket surfaces and doesn't self destruct I'll be amazed🤞🤞

Clutch lever is very loose felt like it was falling apart when it came out of package I almost crashed because the lever won't hold down I had to buy a new one also pedal won't clear the muffler I also had to buy muffler other then that the motor seems to be just fine works really well start first try every time.had a small problem with installing rear sprocket would be much better if they had the sprocket that connects to center of rim instead of spokes for one it's a lot safer and two would be much more easier to install without much problems I wish they had an option to customize whats needed for any particular Bicycle also add instructions to register a motorized bike legally or even add a certificate of origin because some DMVs require it

I sent bike to a mechanic and the motor is fine. What I thought was the issue wasn't. The mechanic found the chain had broken and wedged causing the install to lock up. I will say that a draw back to ordering kits online is that they are not returnable and getting customer service is a pain. I am still leaning towards favoring the 80cc motor kit over this 100cc install. The replacement chains I'm finding are all only rated for up to 80cc. Definitely something to consider. I'm just relieved the motor wasn't hurt after all. It's got power and looks great. Replacement chain is a nightmare to find for 100cc. Will I order another kit again... Ugh I'm a glutton for punishment and probably will do it. Definitely will get another 80cc and probably will give this 100cc another go too.

I have been riding this every day for a week now. Instructions were lacking but you can find a video and details online for install. It's quick and fun and I think it was well worth every cent. Buddy just got one too and no issues.... just make sure you mix proper fuel for it

I needed help to get going parts were hard on first start up motor went south an was told I will get parts to fix we will see

I think every one should purchase the 100cc 2 stroke motor it is stupid fast and so much fun to ride I threw it on a 26” frame mountain bike and I just be taking it on the trials so much fun!!!
