CDHPOWER has two air manifolds, one for each of the 32mm and 40mm intake ports for most 2-stroke engines. 100% made with high quality aluminum, compatible with cylinders with stud spacing 32mm and 40mm. The advance design with O-Ring seals and eliminates leaks that may cause poor performance. Adding up the efficiency is what you should do to improve the performance. The length of the neck is 28mm, the out dia is 19mm and the inner dia is 15mm. This product comes with a 12 months warranty. Please contact them first if you have any questions. They can help you with the problem until you are satisfied.

👤It's a good quality piece. It doesn't come with the o-ring. If you have 40mm spacing, you don't have much meat on it to seal your gasket. There isn't much gasket between the intake and the screw hole spacing. If you have a 40mm stud spacing you're better off getting the berry version for that spacing as it will be much more likely to develop air leaks with this one and with no real benefit.

👤It fits on my yd 100. I almost lost the opening package as it is not on the intake. The air leak developed a week later.

👤This is an excellent intake manifold. The edges and holes were clean. It works for both 32mm and 40mm bolt spacing. My black rubber o-ring was missing, making me fight for myself. The seller should change the listing to not include the rubber seal because it is an outstanding piece. I would buy it again.

👤It is hard to fitERRY on a motor with an NT Carb because it does not come with the o ring. I'm still looking for a good motor.

👤Don't waste your money. There was no oring on the manifolds. Doesn't fit the stock car. I don't know if it will fit with the oring.

👤There was missing oring. You have to buy more stuff that you already paid for because it doesn't seal. You think they would have fixed it now. It is a great product.

👤As a product, cDPower is always a great one.

👤If he had said that the inner 6 hole pattern can't be used with any conventional bicycle design, this would get five stars. You have to cut a hole in the sprocket to fit a disc/sprocket accessory. The Prime version of that adapter is about $29. If you were going to use this sprocket on a disk hub, forget it. The hub mount or rag mount is what you'll have to use. There is a You can cut that hole in the sproket with a variety of tools, most notably a 2-1/4" hole saw and arbor. Or you can use that for a new machine.

👤It fits perfectly and is great quality. I've used it on 2 stroke applications. Works with spoke mount applications.

👤It was built well. Too large for my application. The bolts were lined up but the sprocket was rubbed on the frame. I used a 32t. It works.

👤Most motorized bicycle chains are 410 and this sprocket is for them. I will have to return the product. Weller doesn't mention what chain these sprockets are used for.

👤The size of the sprocket is the only thing to consider when building an 80cc bike. You will need to buy more chain to get this sprocket to max out at 10mph. There is a lot of bottom end Torque.

👤As expected, the sprocket fit and delivered.

👤The machine shop had to make a bigger diameter to get over the coaster brake. CDH 56T

👤My husband said it got the job done after it arrived in time.

👤A decent product has a low price.

👤Good solid chain and breaker links can't beat price.

👤I didn't have my master links just the chain and tool.

👤I am very pleased with this product.

👤The ability to remove chain pins was unaffected by the bent shaft.

👤The ten master links are incomplete and not in package.

The belt drive can be used to replace the 415 chain.

Brand: Sthus

👤The pulley and the engine shaft wouldn't fit the engine sprocket. It should be hidden by side keepers. This product was a waste of time and money.

👤The pulley and gear sprocket are of good quality. The extension spring is useless. The belt is hard to find and worn out in three days. I made the components into a v belt system.

👤I didn't fit my motor because the belt was too big.

👤This is the 8th bike I have motorized and I have an old Schwinn. This is a good kit. I want to convert the bike chain to a belt, but I don't know where to find a kit. The only way to adjust the belt is by moving the wheel back and forth, and you have to keep the bike chain tight. Is there a kit for jackshift?

👤The kit is well made and comes with a belt that is too short for my bike. I called around and asked, but got nowhere. Someone told me to check out Motion Industeries and I will have one in a week.

Brand: Fvrito

👤The product was exactly what I was looking for when I bought it. I ordered the exhaust and within 5 minutes it fell apart because they didn't use a locking nut. Loctite is being put on the nut to fix the problem that I ordered another one to fix. There is a small hole in the exhaust on the second one. You will have to find a way to keep the nut from vibrating off when you use this muffler.

👤Nice product, comes with nuts and washers. What a bargain.

👤I was really excited to finally ride my bike. It wouldn't work and it wasn't happy.

👤Functions fine by just looking at it in the wrong way.

👤The bike's muffler broke in half. It's not worth it to save your money.

👤It wasn't what I thought it would be. It was small.

👤Works sounds great.

Brand: Bh-motor

👤An older model was replaced by it. There is a The float valve keeps the gas inside the bulb from leaking when not in use. It doesn't do a good job at that out of the box. If you want to apply more pressure on the pin and seal it better, you should bend the part that holds the pin. If you know what you are doing, the problem will be solved in a minute. If this is your first, it could take you all of 5 minutes.

👤The leaking bowl float was the reason I bought this. The 80cc motor wouldn't run after it was installed. It ran with the old car, but was flooded by the float. I put the new float back in the old one and the bike fired up and ran well. By the process of elimination, the new car did not work. Why? I don't care. I got a working float for that price.

👤There are images in the listing that show the covered primer plunger. I received a rivet style one instead of the one pictured and it's not okay as I ordered the covered primer plunger.

👤Money was wasted on a valve. It's in the junk drawer because it can't be adjusted. There are no instructions anywhere. This one works out of the box and only has the idle screw. The idle should be turned up a bit.

👤On delivery, choke loose. Problem solved with duct tape. Running for a second, tape loose choke. To keep in position, tape down the head. You should replace tape frequently. It almost works.

👤It's hard to rave over an oem product, but it works the same as the normal product.

👤My husband bought a motorized bicycle at a lawn sale, but it needed a carburetor. I ordered this one. It works great! I ordered one day and had a couple of days later. My husband is outside in the wind.

👤Stock does not have any issues as compared to high performance crap. There are proper cable length problems. Needed adjustments.

7. CDHPOWER Pedal One Piece Stroke Motorized

Please contact them first if you have any questions. They can help you solve the problem.

Brand: Cdhpower

👤I have a crank handle and gear for fifty dollars, but my package was missing some parts, so I bought an extra cup with the bearings and locking nut. I hope it all fits, the dents on the crank wheel look ok. If not all stuff will be sent as advertised, it needs a lower price.

👤The solid crank one piece is a better product than the three piece one piece because it works better and is more sturdy.

👤This was needed to clear the exhaust pipe. It fit perfectly on my bike. The pedals are smooth. Quality is good.

Brand: Cdhpower

👤Poor design and quality assurance. Too much modification is needed on the mount and engine studs. There is a The mounting holes are oblong and should be used for the small and wide mouth motor. The small mouth/studs are meant for the inner most side of the hole. The wide mouth/studs are supposed to fit on the outter most sides of the holes. There is a The manufacturer of these mounts decided that it was easier to make oblong holes about 2mm to short. You have to modify the holes to be wider with a drill or tool, leaving you with a thin edge outside of each hole. This isn't a sound. There is a You will have to cut the motor stud to be shorter so you can attach the mount to the engine because the single horizontal bolt that holds the top and bottom portion together sticks out. If the manufacturer would make the mount wider and the oblong holes wider, these modifications would not be required. There is a The manufacture could make the hole for the horizontal bolt, but that doesn't mean they're in contact with the studs. There is a Most of the Chinese manufacturers don't have quality control measures in place.

👤It is built well but not big enough for the large bicycle tubes it claims to be built for. It would work well on regular tubes.

👤Great! I didn't have to drill out the mounting holes, they already fit 8mm mount studs, which was a nice surprise.

👤They came out with this so I don't have to worry about cracking my frame. This thing has a lot of vibration.

👤If you bend the crank arm around the mount, it won't hit the exhaust, but if you don't, the engine won't fall off.

👤The mount worked well for the cruiser bike, but it won't work with the V bottom. I put the 80cc engine on the bike, but it wouldn't fit without the mount.

👤It was to lose too much.

👤I assumed this would work for me since I had busted a bolt on the front motor mount. I tried to use the Universal Motor Mount on my bike, but it wasn't a good idea, and I had to remove the long bolts from the front mounting brackets. The way it is made is a bit over sized for the way it is used, and I used a different bracket in combination with this one to make a functional system for the rear mounting.

👤Is good. Modifications work great because it fits the bottom rail of the bicycle.

👤It lasts a long time.

Brand: Alyone

👤It is a Jet, what can I say? There are 5mm threads that fit Speed NT Carbs. The size is printed on the side of the jet, which is great. This is a must buy if you want to get the best performance out of your motor.

👤Unless they give you a cross Guide to reject a Mikuni Carb, you are out of luck. The jets were purchased for a good reason. I find this laughable because it states it works for my bike.

👤The vm22 clone I bought from Amazon was the same one I swapped the pit bike for. These and other sizes work perfectly for me. It's better when you can jet for conditions.

👤The B-set works great in my 2020 Kymco Super 8 50x stock car. The heads are slightly larger than stock.

👤I bought these for a knock-off. These worked well for it, but the car was not up to par. I was surprised to find these also fit the 26mm nibbi, I purchased a Nibbi which was 800-211-2519

👤You have to measure each one with a welding tip cleaner because there is no size stamped on these jets. The butt has pain. Do not recommend.

👤The jets are large. They won't fit in the trx90

Brand: Hiaors

👤Came very fast but it was damaged from the factory. The box was not damaged.

👤The fuel line is weak and the tank looks like it will last a long time.

👤No nuts for the bolts, it's a strange size, nothing fits, it's a bit of waste of money.

11. Anbull Bicycle Engine Motorized Fuel Efficient

Anbull Bicycle Engine Motorized Fuel Efficient

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.

👤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.
