👤If you don't know what to do, just go on to the video and see how easy it is to put it together. There are lots of videos about these motors. I had a problem with my bike when I put gas to it, but I just put the tabs on the float and it solved the problem. I recommend red Lock tight and if you don't have an innertube try to find a old one, it's a lot of fun and you should buy it again.
👤Installation was simple and all parts were correct. It was easy to start up. The engine began to clunk within 1 minutes. The bike was stopped to examine the housing. The nut was loose and the tread on the shaft was stripped. The threads were fixed and the nut secured. I tried to start again, but couldn't. There was no spark being sent.
👤It's cheap and it's worth it because parts are all over the place. They all have a washer or 2. Overall 3.5
👤I was completely satisfied with this kit. It took me only a few hours to build it and it exceeded my expectations, it is one of the best things I have ever bought.
👤Good motor. It's better than the last brand I had.
👤The setup chain was too short and the clutch lever on the left side of the engine was short. The speedometer won't connect to the bike.
👤Fue un poco complicado de armar.
The center to center spacing between the pins is approximately 7/16" wide. The engine is the 100CC. They used a generic version of the user manual for 80CC/100CC because they look similar. It comes with all the necessary hardware for easy installation. Heavy duty metal engine body. The max.speed was 48 km/h. Fuel type : 90#; N.W: 11 kilogram; G.W: 12 kilogram. It's for most 26" and 28" bikes. The frame should have clearance between the bottom brackets and the top bar of 9-11mm, and the diameter of the frame tubes should be 25-28mm. 50mm bore single piece cylinder, an upgraded CDI, Performance Speed Carburetor and more, high performance Speed Carburetor, silver anti-corrosion coating, high performance CDI with Yamaha components, improved magneto, high end allen bolts, improved gas cap. The mixing ratio for fuel and oil is good for the first 300-500 miles, but it is not good in the summer because of the hot weather.

👤The bt 100 engine kit is uncommon to fine one of these engines. There are a few issues with the bt 100 engine kit. The magnet seems to be weak on one side. If I am able to find a replacement, I will have to.
👤It was a great way to get back and forth from work. It was amazing to feel that kind of power on a light frame bicycle. I added a 36 tooth sprocket and it definitely increased speed. It went from 30 mph to 35. I added a air filter and rubber motor mounts to make the motor less vibrate. All in a great product. It is very easy to put together.
👤The motor kit is great and there have been no issues so far. It's worth $200, but not if the exhaust isn't able to upgrade or change, my buddy built it for me and you can contact him on his Facebook page called - New motor bike builders.
👤They changed the engines. Either that or they have a few different ones. I have no issues with the motor. The chain was changed to a two bolt because I didn't use them enough. There is a great engine with lots of power.
👤I built and bought many engines because I use them for my food delivery job for two years now. The engine and accessories are the best yet. The bigger and better design of the carb makes it non-standard. If you buy a 100cc engine from bike berry, they will send the other ones. If you tighten the studs all the way in, they are not long enough to put bolts on. The other accessories were all of the same quality, and it looked like this guy took the time to package them. One thing I like about it is that the head came assembled, everyone else started making the customer do it, which is a pain in the ass. I just connected it to the bike. I learned that you have to be careful with the journal bearings, there is only a small film for them to ride on, and 3cc of oil in the crankcase, on my last 100cc from bike berry. Don't accelerate down hills when the engine is not running. I'll never find a 2 cycle engine that will get more than 5000 dollars worth of food deliveries done, but I will update when this engine takes a bad turn. It was an edited version. The motor took a bad hit on me. It has been 3 or 4 months of hard work delivering food. This engine has made me more money than any other. It was probably my fault since I forgot to put oil in my car before I left the gas station. It can happen in a few seconds if the circumstances add up. My mind is against me, and it's been so long since my back tire or my engine had ruined my day that it had to intervine! What an ass! I watched the destruction of the engines. I bought an extra one, I will be much more cautious and get an accurate picture of how much better this engine is than the rest.
All of the original parts are backed by a 180 day return. The bike is a 2 stroke motorized bike. The package includes a clutch drive gear. Brand new and high quality. This is a replacement part. Make sure that it can fit your machine by comparing its appearance, shape and size with your original unit. This is a replacement part. Make sure that it can fit your machine by comparing its appearance, shape and size with your original unit.
👤I bought this one to replace a faulty sprocket that came with my 80cc bike engine, and it was spot on. The one that came with the engine had cleaner cut teeth. I had to modify the keyway to fit it, but it works great after that.
👤I bought this to replace the engine kit that was the wrong pitch and would cause the chain to break. The gear has a closer pitch to the chain. I had to widen the keyway with a small file and a hacksaw. The pitch on my chain is.475 inch. If I need one of these for the next build, I'll buy another one.
👤A very nice price for a replacement gear for a bike engine.
👤This was rusty and very disappointing.
👤It works and it is a good price.
Top quality. It was made in Taiwan. One year warranty. The package has a chain tensioner kit. The package has a chain tensioner kit.
👤It's a bad thing to keep your chain on your 66/80cc bike. I had a cheap stock tensioner bend and break a lower frame member, and also had the chain jump off once on another motorized bike before I bought this tensioner. I have had no problems since. I moved out of state for college and had to leave my motorbike behind, but I'm building a new one and so I just ordered another one of these tensioners. I wouldn't feel safe on a 66/80cc 2 stroke motorbike without one of these. If you have a cruiser frame, the pedals should clear the allen bolts that hold this tensioner on, but if you have a mountain bike, you might or might not have to install wider pedal cranks.
👤I was very pleased to use this to tension my chain. It seemed like a better solution to the stock. The pulley melted into a ball of plastic after only 3 rides because it nearly fell off twice.
👤Returned immediately after receiving. I am not willing to make modifications that would not fit. The pedals can't clear because the bolts stick out too far. Cheap materials and rough edges. Amazon is starting to sell a lot of junk. The quality of the products sold on Amazon was better when I first started buying them. I don't recommend this kit.
👤It's easy to install. The nice side was against the casing and the rough side was against the pulley wheel, so they stamped the parts out the wrong way.
👤There is a false advertisement. They are not Allen bolts. It's rude to have a sudden change in product and not say anything about it when you're sending them with Allen bolts, because the hardware still works, but it does not look as good. When I opened the package I received, I found that one of the main plates was bent and that I had to cancel my order. It looks terrible. I will give that 5 stars because the one I am using is awesome. It looks good, but not the last two I ordered.
👤The product was delivered on time. If I had measured b4 ordering that would not have been necessary. Thank you...
👤Excellent tensioner. The spring is good and tight, but could be improved with a metal wheel. The plastic wheel is wearing out fast so I'm going to have a metal one made to improve it.
👤The one that comes with the motor kit has a replacement tensioner. Get this and throw that junk away. It makes sense that I won't get into the spokes.

For use with brake levers. 49cc is a good fit. 50cc 66cc 80cc. A bike is Moped. 1x sprocket is included in the package. Rear Sprocket Mount can be used. There are mounting pads. There are kits for 9 hole Sprocket Mount. The use of the 3 holes Sprocket. The Rear Hub Disc Brake Ball Bearing can be used.
👤It took me an hour to install the stock rubber things that they give you, but with this sprocket and the cnc adapter that they also sell, it only took 10 minutes to install it all. The thicker the sprocket, the better it holds onto the 415 chain.
👤The sprocket is great! Hold up well. I got a lot more speed as well.
👤The lowest cost for increase speed. I was able to get 45mph after installing a 32 tooth sprocket. They fit my new mag rim. Money that was the best ever spent.
👤I love that I can hook this sprocket up to where my disc broke. The sprocket is very strong.
👤The mini bike does not fit on the inner holes.
👤This is the best speed sprocket I have ever seen. I put it on my Niome 80cc along with others and it gave me a cruising speed of 46 mph and I call it the Speeding Demon.
👤It was quick and inexpensive to get a faster top speed on my motorized bike. Make sure you use locktite and get a hub adapter for the sprocket.
👤The ride is better now than it was with the kit. I'd say it's much better, faster, and locks up on me.
👤Good quality came on time and the 80cc bicycle engine went faster because of it.
For use with brake levers. The Firestorm Zeda 100 HP bicycle engines have high performance heads. 50mm bore, 40mm stroke and US displacement. 78.6cc/40mm Intake and Round Exhaust. The rod is long. Increased weight capacity, low operating temperatures, and sustained power output across rpms. The coat has pearl anti-corrosion coating. The spark plugs and thicker crank case are used for bearings. Improved single piece cylinder, high end Allen bolts, and improved gas cap.
👤I will be adding another review once we get it working but so far the kit is very nice and I installed it on my bike, but this is not for a regular person, it is for someone who is advanced in a mechanical nature. I will have fine pictures soon. I got the bike working and it was a beast, this little engine got me going real fast. If you rate this item bad, I will give you some pro's and con's, but you should know that kit's are likely to give you bad items. Before you buy a bike, read if it will fix it. It's not hard to install a great engine. Heavy duty chain. It's easy to start Kit, but I'm not sure if it's worth it because you can ruin the engine and the throttle. You can pedal while it's on, but you can't pedal while it's off, I thought you could, but you can't! There is a It's hard to install and see where to put it. The Sprocket is cheap and will be upgraded later. It will not last long and you can get a racing spark plug for cheap. You need to drill a hole in your bike to put the throttle on. I didn't. I plan on doing it for safety. You can buy Greece for the gears and put them in every 6 months. I have to connect something to the Muffler because it bounces even though I tightened really hard. The kit is an amazing deal, but just some cheap parts.
👤So far, so good. Not a lot of miles yet. It runs smoothly without maintenance issues. It is important to have installed by an experienced technician. 3-23-2020 It's been 3 months and still running efficiently. There has been no engine maintenance needed so far.
👤This isn't made to fit on a quality bicycle frame. It seems like a good value. It doesn't fit anything perfectly because it's a universal kit. I mounted my kit on a mountain bike, but it took some modifications. The kit was designed for a cheap steel framed bicycle. My frame is made of aluminum and has larger diameter/thinner walled tubing than a cheap steel bike. I had to use a vice to "ovalize" my downtube to get the bike's frame to fit. To get the seat tube in the frame, I had to cut down the rear engine mount yoke in height and open up the saddle for it. There was not enough height to install the boot without a war and there was not a way to tighten the plug. The rear engine mount had a huge air gap because the angle of my frames' tubes was different than what the kit was made for. The mount was packed into the air gap to make it solid. There is a The next procedure was the intake. The stock cast aluminum intake put the seat post in the correct position. I had to cut the "Z" style intake down to an "L" and run it back and forth at 45 degrees after ordering an offset steel "Z" style intake. After attempting to mount the exhaust it was apparent that the exhaust went directly into the downtube of the bicycle so it was modified with several "pie cuts" that were welded shut and ground smooth. It seemed to work after it was installed and modified. It's rich and boggy on the bottom and the top, so I need to tune it. It's not fast, there isn't enough Torque to make it "zippy", but it's fun. This little thing is fun and sometimes less is more. I use it to run down the dollar store in town. There is a It's fun and cheap and I think it's worth the money. Prepare to cut, grind, bend, beat and cuss. Anyone with a can-do attitude and basic hand tools can make this fit nicely on a bicycle.

👤It stays put when installed correctly. Does not slip on the hub. It doesn't put any pressure on the spokes. I mounted it to see if it moved forward under load. They should make a true 1.0 inch adapter for mountain bikes. I used this on a trek 822 which is over 1.0 inches and it fits nicely. On a true 1.0 inch hub, the sprocket adapter is too big and won't fit around the wheel axle housing. P.S. If you are using the motor kit 44 tooth sprocket, you have to drill 3 holes to line up with the adapter. You will have no problems if you buy a multi-hole sprocket.
👤I couldn't use it because it didn't fit on my rear hub, even with a machined one.
👤The pic is misleading. The picture makes it look like it is 1 peace.
👤The machine work was of good quality, but they forgot to finish. One of the holes where the sprocket bolts down doesn't have a hole for the aluminum spacer to fit in. The sprocket will not run non-concentrically and will have extreme runout without this recess. The products are useless because of this.
👤It does not move after being tightened.
👤The bike upgrade is pretty sweet and the price is great. Compared to time wasted taking apart a bike tire due to broken spokes, as a result of a cheap deseign of the original sprocket atttachments that are included with most bike kits.
👤You will have to drill 3 holes if you plan on using the sprocket that comes with the engine kits. I don't like the bolts provided. I will swap them out for regular bolts.
👤There were slips and breaks. It cost a lot of money to buy new wheels.

👤I gave this product a four star review because I thought the little screw for the cable retainer would be excluded. I'm at fault for not knowing that it's not part of the package. I was still disappointed that it didn't come with it. Because we don't always have access to those types of screws and who wants to drive all the way to a hard ware store for one little screw? It's still a great deal.
👤A good deal on a few pieces that wear out the most and a few extra pieces is always a bonus. I will definitely be back next time, my bike is way over built and a daily driver to work and back, so these parts are a must have on reserve.
👤I tried everything I could to make them fit together, but it wouldn't do the job if I gave it negative stars.
👤Someone was paid to delt with bicycle engines. He rode cross country with the same engines. He was amazed by the engines. So far it works. If you want to stretch out, you have to shorten it, but a better quality one is better.
👤Product came in tact and usable after a long time. There were no issues connecting the clutch and still using it.
👤I can make it work if you take off the motor's parts. There's a lot of people out there. This will be a big problem.
👤Everything was needed to replace my clutch arm and cover. 15 minuets and done.
👤A lot of people have the same problem getting the wrong parts.

👤If the builder knows what they are doing, this motor is very powerful. There is a The builders who have used this motor say they are disappointed. They weren't fully aware of what it could do because of the incorrect install. This motor can produce enough performance for a 300lb rider to reach 55mph on a Razor MX500, if set up properly. It is powerful enough to do a wheelie and throw a 300lb rider off the back with no issues. Yes... FLING... A 170lb rider on a Razor RSF 650 is going to get to 66 mph on a flat road in subpar conditions. A quad to 37mph, a Pocketmod to 49mph, and an SX500 to 58mph are not stable. There is a There were 8ah batteries. The original #25 chain and rear sprocket were used for these speeds. There are some things that are CONS: The package that this seller sells seems to be the cheapest one. The motor stand on the bottom is what "foot" means. It doesn't mean foot pedal. It doesn't translate. Most things don't translate. It's easy to understand or at least figure it out. The wires in the harness can be mixed up. If your motor is not running in a straight line, you should move the hall sensor wires around. The colors are green, yellow, and blue. The 3 speed switch wires are often messed up, so you have to switch them around to find the correct one. You don't have to use all the wires. They are not very good. Cut them off and get some other things that would be better. There is a The seller gets 4 stars because they are very good with customer service. There is a It is worth it. You will have to ignore the people who say it's bad because it's in Chinese.
👤Plug and play. I've been pushing the motor hard on this 2x2 vintage Rokon trail breaker. The batteries are wired in series with a standing voltage of 82.3
👤My Razor RSF650 can go up to 45 mph on a flat surface and 40 on a slight uphill. It's a trip that keeps up with traffic. The kit has sprockets. It is ok. You could get better performance with a larger rear sprocket. I would say this kit gave me what I wanted. Installation was relatively easy and I was surprised at how compatible it is. You need to have an idea of what you're doing. I read all the reviews before I bought this and I'm pretty sure that everything negative said was either something not installed correctly, not connected, or issues with the battery not this kit. The 54 tooth rear sprocket has been swapped for a 62 tooth one and the top speed is now 35mph.
👤The product is not damaged. I got it to convert my bike. The mechanics and electronics are all working for me. I don't know what the hard boot wires are for because I tried to start it but nothing happened so I disconnected it. The motor controller doesn't do electronic breaking, so I needed to mount the motor so the sprocket was on the left side of the bike. When the motor controller is first disconnected, I'm going to have some relays in series to connect the three phase rectifier back to the battery. I haven't tested it yet. The direction of the motor's spin is important because the controller does not allow full speed in the reverse mode. You need to do the same thing to the leads of the holifex. The holifex has a lot of cords. There are two red and two black ones for power and the other three correspond with the main motor inputs. I changed the color of the motor. I tried it on the holifex and it didn't work because they didn't correlate the color of the wire in the holifex with the color of the motor, so you might have to cut a strip and try all combinations. You have to wire it to go in the other direction. The wires from the controller should be cut. The Chinese on the handle is a complaint. It's easy to remember once you try them all. If you want other people to know, you can take a Sharpe marker and Mark 123 and FR on the switches. 1 min to do all of that! When I get a battery with enough power, I'll add some statistics, but a 5p 12s battery got me to 15mph on a road with a low setting. Med and high seem to try and stop. I think my bms are controlling the controller. I'm going to test it, but someone said it could get you up to 60mph. There is a It can be hard to figure out the wires coming from the motor controller. I'm going to make a completely new battery that will be 20p by 20s, and I'm going to make it in four separate packs, each with 20 rows of nickel, to give me the maximum amount of nickel to spread out. I'm going to use 20s bms. If you want to make your own regenerative braking on top of the rectifier, you'll need a 1500w boost conversion with constant voltage control. The solar panel can be plugged into the boost conversion to charge the battery. If you want to charge the battery with a wall outlet, you can get 1100w for 30 bucks, but you need to research ahead of time how to turn it on. You might want to look into a step down from 72v to 12v to power low voltage equipment. I would suggest getting the step down to 12v and then a 12v to whatever you need because a lot of DC stuff uses 12v. A battery power output monitor is a good idea to keep track of Watts and battery voltage. If you're going to use this motor, it's probably the cheapest one for the wattage, but the in wheel motor is a lot more compact and takes up less space in the frame of the bike that could be used for battery. I just learned how to make an in wheel motor and I think I would probably make my own motor and motor controller, even though I don't know a good source of cheap coated copper wire. This is probably the best option for the average Joe, but they should buy a chain tensioner. It will save a lot of trouble if you just do it.

👤It is a good accessory. It's easy to install. Be aware of the size of the sprocket. It will take away a lot of power. If you live in a hilly area, you may not want this size. It's more for speed. The stock has 44 teeth. The smaller the sprocket, the faster you can go on the flat land. Unless you are light?
👤It was easy and fast to install the sprocket and adapter. The blue Loctite solution worked great after I got stuck in the wheel after installing the adapter and sprocket, after some research, I determined the solution was blue Loctite. I had a small problem with the sprocket being not true and requiring some adjustment but still working.
👤I have built a couple 2 strokes and a 4 stroke in the past, but I have never built a 5 stroke. I have used different teeth gears, and this one is perfect for me. You gain 20% on top end even though you lose a little Torque. The hub mount was very nice. The sprocket is a bit thicker than the original, which is nice. Someone took the time to grind the teeth so they would seat correctly in the chain. You don't need a different drive chain. The price... The product was sold for $75 and up. This is a scam for 30 dollars. Very impressed!
👤It was reasonably priced and shipped quickly. It seems that they don't take much care in maintaining their products quality. Most of these damages are caused by the fact that these are thrown into buckets. There are dents and swastikas on the surface of the adapter and sprocket. I will have to remove rust from the threads of the bolts. Quality product seems to be neglected, despite all these things in mind. The metal looks good. Once I install, I will find out. Due to time constraints, I don't have the ability to return this item. The kit will not look pretty if you purchase it.
👤The sprocket that came in my 100cc motor kit was 100 times better.
👤The bicycle engine kits come with a fantastic upgrade to the clamps style adapter.
