Are 2-Stroke Bicycle Engine Kits worth it? Let's find out!

So over the past few months I've had hundreds requests to do testing on two-stroke engines Now I've got about eight or nine two-stroke engines whether they're weed trimmers or snow blowers I have all sorts of two-stroke engines, but I really wanted to do something different So I went out and found a two-stroke bicycle build a bicycle kit for a pretty good price online Now the price is probably indicative of the quality. It was only I like $120 so I don't think this kits very good But if it needs a little modification to make it work, I think we're up to the task So anyway, let's go and get this project underway and put together this bicycle and just see how it does. All right, let's see What's in this bicycle kit? First step I'm going to make is to go ahead and remove the rear wheel and install the sprocket Sure looks a lot like a recycle tire. These little rubber scraps are not quite consistent So it's very important that I get this sprocket centered up perfectly and unfortunately It's going to be pretty hard to do unless I shim it up with something so what I'm going to do temporarily is use some zip ties to stick between the sprocket and The axle itself the hub itself and that's gonna help me shim it up and make sure that everything is spaced. Just right These bolts are not that tight So now I'm going to ahead and tighten them down a little bit more and when tightening these bolts it's important to do it incrementally Just like you would any part that Has a lot of flex in it House you can see I've got the sprocket installed the space between the hub and the sprocket is even all the way around it did Not have a very tight fitting and that's why I use those zip ties so what I'm going to do now just spin this wheel over just to make sure that the sprocket is Balanced and that's also fairly straight Okay, that's pretty good that'll work really well So before I put this engine I'm really curious Regarding what the inside this engine looks like and I'm also curious about how much torque is applied to these head bolts So I've got a little torque adapter hooked up to my wrench I'm go ahead and take this Sutter head off and then take a look inside Okay, that was torque to 9.2 foot-pounds of torque 11.9 k-8 point five and seven point three Okay, all that sara is an aluminum gasket there's an oily coating inside on the cylinder Okay, it looks like the back bike mount will work but the front bike mount is too narrow Then this kit came with it looks like another Universal and my adapter So I'm go ahead and swap these two bolts out and put the other adapter on This is definitely not the way to do this if you want to keep these bolts But I don't plan to ever use these again. I just need to get them out I'm gonna remove the rubber handle grips. These things can be difficult to work with rather than getting these all oily I'm just gonna use compressed air and a nozzle. I learned this trick many years ago Okay, this is the clutch assembly so I'm going to do is just connect this cable to the clutch assembly This little spring here is nothing looks like nothing more than just a heat shield spring so it slides right over the cable keeps it from touching the exhaust and melting and There's a little bracket here in the back that this cable will slide through So what I'm gonna do now is just put this little spring in place Slide through the clutch assembly There's a little piece that will allow this cable to stay in place Now the gear should spin freely and it does So next time I hung up the throttle cable, so what I have to do There's a little dowel that needs to fit into this handlebar. It's a quarter inch. So what I'm going to do is just mark my Handlebar where I need to drill a hole and then tap a quarter inch hole So anytime I have to drill a hole in something that's round I like to use a center puss just to sort of create a little Indention that allows a drill bit to stay in the right place while I'm drilling Okay, now we're going to go ahead and put the throttle cable inside the carburetor If you look inside the carburetor you can see the carburetor is cooperating and working correctly Okay, imma go ahead and install the coil So the gas tasting arrests right on top of these cables and that's going to be a problem because I won't be able to use my brake So what I've done is I've split a piece of PVC pipe which is going to overlay these Cables and when I clamp the tap they tank down. I'll still have freedom of movement for these cables So I want to install the chain guard I think chain guards are pretty important, especially when the chain is this high up because loose clothing could get caught in it So the front of this is supposed to attach near the front sprocket in the back is supposed to be zip tied Around this frame and as you can see, that's just not going to work It's going to come in contact with the chain. At least it is at the bottom as well as it's all contorted So what I'm going to do is I'm going to just cut a little bit of metal out So it'll fit nice and tight up against the frame and I'll poke a couple holes in this and zip tie it together So it'll have a nice secure fit One thing I want to point out is this fuel tank came with a pretty good sized dent This dent is larger than the diameter of my finger and it came that way I guess damage and shipping not a big deal because I'm just gonna use this bicycle in this engine for the video test But for something that's really concerned about how their product looks this may be an issue So just a quick rundown on how this is supposed to work Obviously the engines gonna have a choke. So if you want to start this bike what you do is wheeze the clutch lever it disengages the engine so the chain going to the engine spins freely and There's a little button that you can push in that keeps the clutch from being engaged Because the minute that clutch engages the engine the engines gonna want to spin over So, how do you start this bike? You want to get pedaling get a good speed up? Let the clutch out it's gonna spin the engine over in its start there's a stop engine switch on the near the Accelerator so you can just push the clutch in shut the engine off keep riding or you can just you know Use the shut off switch when you're near a stop So what next up some fuel this requires an 18 to one mix during break-in period which is several tanks of fuel That's really surprised. This thing is probably gonna smoke quite a bit Well that two-stroke bike build was a lot of fun but riding the bike was even more fun That is quite a nice little kit. I was really impressed with it how well it went together Well, I didn't find instructions for it in the box. I did find some online It is a universal kit requires a little bit of modification But not too hard to put together Also the bike seems to run comfortably between 22 and 25 miles per hour much more than that And it seems to vibrate a lot the engines just not very refined. It tends to really shake quite a bit I was really surprised at how much it does shake but 22 to 25 miles per hour is a lot faster than I can Pedal on a continuous basis. So it's a big improvement over just riding using my own power Anyway, just want to say thanks to those that recommended. I start testing with two-stroke engines I plan to begin testing with two strokes really soon Thanks so much for watching the video. Please take care, and I look forward to see you next time
