Got up to 47 mph down a hill on a Scott Voltage MX3 with Bafang BBS02B installed. 52/11 + hard pedaling. Those hybrid or hard tail MTB are nice at speed, though not as aerodynamic as a road bike.
@TimpBizkit I can do over 50 with the ztmoto v3 phantom 85cc 52mm bore just slapped basic shit on it like a expansion chamber race carb better cdi and a 38 tooth sprocket I don't like 36 not enough power going up hills
People in my city are still caught off guard when I pass them on my gas bike and it's built for speed but not 75mph. I couldn't imagine going that fast
@@JDProductions_YT cdhpower super pk80 Ported with vm18 and nasty jack pipe and 36t rear sprocket using a red wire ignition coil, I just added a reed valve and waiting on a windowed piston and new jet kit
Idk man my chain kept coming off when I first got mine an it gets caught between the bolts on the sprocket an the frame. Pretty much locking up my back tire and almost messing up the chain. I've been 170 mph on my Yamaha 1000 but never again, and I would definitely not go that fast on my bicycle I'm afraid it will fall apart it's cheap made lol. He's got some balls though 😂
i agree that the risk of the chain whipping into the back wheel somehow is too great a risk for me to exceed probably 30 miles an hour on one of those things. and even at that speed an end over end crash would be devastating. thats why im looking at getting a razor RSF650 and then upgrading it before next winter so i can rip up the snow in it XD@@ryanpriddy2376
when it simply snaps it doesn't just evaporate, its snaps and then it has to go somewhere, into the workings of the bike is one of the spots it has a non-zero chance to go@@kennethlabossiere5677
That's why you build it right with safety in mind. For one, this is how motorcycles were made from the get-go and then evolved into Harley, crotch rockets, etc. There's no way this man could go 75mph on a 2 cycle without some serious upgrades! I know of a guy who built a bike with a 120cc Honda motor that goes over 100mph!
It was this video that got me hooked on this hobby. Now Ive got three, though the third is a work in progress. I got charmed by the jackshaft gears snake and now my hours are spent trying to put my hybrid, stage 3 ,(gas and electric) jigsaw together. I doubt its gonna be as fast as this though. Thanks for posting this vid those three years ago.
I hit a cat going 25 on my electric bike it sanded the top half of my seat it flipped me over busted my pedal ripped off my big toenail I couldn't imagine going that fast 75 miles an hour and racking your balls you better have alot of supper glue holy crap
This is definitely the best way to do this. At night on a major interstate Highway with no lights and a truck tailgating you at 75 miles an hour. But the helmets a little overboard
Helmets overboard lol 😂 he is going 80 on a pedal bike 🚴 also if you own one you know how easy they can brake while halling and if it does your screwed
@@EDGE_AXISS doesn't mean you don't have to use helmets though, just wear one and you'll have a chance of surviving. matter of fact, maybe don't ride with a lot of cars, then you'll have a higher chance of surviving. at those speeds anyway.
I barely hit 15mph last week on a quick build on a sketchy bike. It was supposed to be my commuting bike, but I realized those days are behind me. Flipped it the same night for $125
hell yeah i fell at 15mph on a test drive on a new build i just finished up going from the street onto the sidewalk change hurts alot more that im no longer young. picked my ass up finished the test ride had a firesale on that bike. had it sold for 150 before i finished the test drive.quick flip only paid 50 bucks for the bike w motor. first time working on a motorized bik the other people tryna sell motorized bikes for like 300-500 they crazy. just get a motorcycle for few hundred more faster safer
@@mcchillindaily4581 shit i busted my ass on the street to sidewalk gradient change at 15 mph and just a tip based on my experience thru trial and error to anyone building a motorized bike or thinking of building 1...DO NOT USE 700c tires go 26-29 inch hybrid or mountain terrain tires...
Sweet, I built a 80cc petrol beach cruiser. Shaved the piston and took out the baffle added a 36 tooth rear sprocket. Got 45mph out it. Man I had a lot of fun with that lil machine 😂🤘
Dude has balls of solid rock, riding a bicycle at those speeds is extremely difficult and quite dangerous. I have an old whizzer with the ohv upgrade that does 50mph I can't imagine approaching 80mph. Dude can really ride.
I shudder to think of all the parts on that bike that might break at any moment while doing 75mph, they aren't rated for more than about 25mph. This is just stupidly dangerous on so many levels.
Well no the stock motor isn’t rated for 75mph it’ll never do that. This motor is built with proper internals and externals. build it the right way and you can do this all day long.
@@landosaquatics No, it's notthe motor that is the issue, it's the bike itself, none of the parts are made to go 75mph, even the tyres aren't rated for that speed. Hence, it's dangerous
And he has got to have some nut locks on them damn Wheels. That's like us strapping a rocket on a Cessna plane and trying to shoot through the atmosphere LOL
I'm just an old cowboy that likes riding my 79cc motorized bicycle but bloody hell mate your getting it on yours!!! but I don't think it will do to well with the mountains we've got around here at 5575 feet above see level. Y'all would need a bikeberry 48 too a 56 rear sprocket just to get up hill 🤠
Oh yeah, I bet you’re “flying” at 15mph and you reach top speed in half a second 😂😂😂😂 thats too big of a sprocket man, you don’t need that. 40T should be more than enough for steep hills on a on anything above 66cc
I want to go as fast as possible with these engines. Issue 1 is, the rating of the tires. Couldn't find motorcycle tires that would fit a 700C or 26" bicycle. The best I found were e-bike tires from Schwalbe rated at 50kph. Second issue. Looking for affordable mountain bike frames that have enough room in the frame for the engine, because the shock is at the top tube of the frame, or behind the seat post tube. And I still don't know if those spring tensioners that hang off the engine, still hold the chain, with a rear suspension going up & down quickly.
Its all custom built. Cnc case from Ryan Darragh, Am6 cylinder..custom cooling system..Oko carb. This is not just bolt on parts..roughly about 13-15 hp.
Impressive! But be careful! That bike isn’t designed to do those speeds! But if you ignore my warning, please at least video all crashes and upload! Lol thank you
The main question will be. How long can you ride that bike at that speed without being to hot? I mean the weak point of this 2stroke motors got solved/improved with the water cooled kit right?
Amazing. 1 more cuestion thought. How do you isolate the coil/magnet from water or rain ? Given that its exposed, or maybe I saw wrong on the other videos.
So I just built one myself I got the 100cc one I was riding it last night got it up to 50mph and still had half a throttle to go. I pussied out and let off. In my defense there is black ice everywhere as it's still the middle of winter wish I could post some pics
