Crystalyte X5 5303 Bicycle Hub Motor Going 45mph

[tori8984]

Looks like florida, reminds me of Port St Lucie, but is probably near Orlando.

[bg0821]

is it just me or when he's counting speed 43mph, 44mph then it sounded like he said twenty five mph lol I thought you just made a mistake there in your speech.

[packagewarren]

you're probably right, sorry.

[packagewarren]

you should've ran one of those smart asses over for not moving over. they heard or saw you coming. taking up the whole road, instead walking single-file. i would've hit one. i hate smart-asses.

[jccourtney317]

@packagewarren And you would have been more seriously injured, if not killed, than the pedestrian walking due to you getting thrown from the bike.

Cool vid but did take a while to get to the nitty gritty 45mph

[MaxSachs]

@Reders160

Heheh

[mcmanus1806]

what size and type of battery are you using?

[blackstarfrommars]

what...about...his nuts?

[deejimmydee]

What's with all the loud groaning? Aren't hub motors completely silent?

[MaxSachs]

You got brass balls riding at that speed, you'd better have disc brakes on that thing for your sake. I'm amazed at the low amp draw at such high speeds, what motor brand and model are you using?

[Ham549]

@MaxSachs If he is running at 72 volts 10 apms would give him 720 Watts of power

[henik9]

Imagine if you hit a pot hole going that fast. That'd suck hard..

[0verboardproductions]

your a legend.

[zabnichols]

Where did you get the motor, and what motor is it?

What kind of batteries are you using and what kinda range do you get?

Thanks.

[OrthodoxSteel]

That is too fast. You are very very bold.

Now tell me how to do it!!!

[phxdrummer16]

How much was this to do? conversion wise..

Wicked! i am buying a Wilderness Energy BD 36Volt 600 Watt Electric Motor Bicycle Conversion Kit today. Gonna run the lead acids into the ground and build a custom lithium ion bank and maybe a custom speed controller preferably open sourced. ;')

[johngorgis]

i go faster on my bike

[HydroSonic88]

i bet those people walking were like "WTF" lol

[ez3usx2]

sounds just like my moter.nice video and bike have fun.

did u see the lincvolt car neil young the singer is trying to build?i'm betting the possibility of a 100 mpg 1959 lincoln could be done.i thank neil young for putting his money time and life into this.

he needs our support as much as the world needs his right now i think.

awesome. I gave it 5 stars. Just be safe.

[turboshagna]

That shit is awesome!

fucken 40miles per hour! 100! miles per hour! 200miles per hour!! 600!!!!miles per hourrrr 2000miles per hour!!! 15000 miles per hourrrr i cant slow it down. 19000 miles perrrrr hhhoo9uuurrsa

[Nevawake]

i got 4 negetives for this comment stupid people do u have a sense of humor?NUT!

Im into ebikes. Watch the video and if u have an imagination u can see why i made these comments. It feels like he is breaking speed records. ha ha :-(

[Nevawake]

thats a funny one man.. Cool.

[djanarak]

I think something that powerful is better suited to a vehicle with more than 2 wheels. I was cycling around 20+kmh on a normal bike when by front tire popped. Luckily nobody else was on the road, or else I would've run smack into traffic in the opposite lane. Be careful, because most bike tires arent made for high speed. But I very much appreciate your vid, great to know such a motor would go nicely on a go-cart.

[analyzingfunny]

Sounds like someone LIKES the big oil companies!

[trumpettom001]

I've hit 45 km/hr on standard tyres and not had a tyre pop - generally the only cause of punctures is sharp things - thorns, glass, and in my area - drug needles.. how many p.s.i are you inflating your tyres to??

[bcdeines]

are there speed limits on a bike? (not sarcasm) where are the cops?

[XxZandderRxX]

Where are the cops? where is anyone? not seen a single car or anything so far....

[cdevidal]

Check your municipality's laws... here in Florida in the USA I cannot exceed 20mph which is a bummer...

[cypher955]

in some states, you can do 25 mph...in my state, I can legally do 25 mph...and my e-bike goes 31 mph...I regularly do 31 mph and have gone pretty fast even in front of cops and they don't care

[dynomania]

Hehe That thing really gets along, is it running the standard voltage ? will it handle more ?

[bcubed72]

I'm worried about the high DC voltage. Obv. high volts are good for generating power w/o loads of weight, but I've heard the reason aviation stopped at 24V is 'cause much higher (DC) risks greivous bodily harm...do you feel safe against the possibiliyt of a short?

[eRustler]

Mine runs at 48V and I've never experienced a shock or anything. DC current is much safer in a shock anyway, Alternating Current will stop your heart given the right path..

Most of the kits come with a fuse, and most builders know to put one in if building from scratch.

If anyone is interested in building one of these, you have to use a bike that has steel dropouts for the wheel, and if you're mounting it on the front wheel, it can't have shocks on the front fork.

[raypsi]

bcubed72 it's current that kills and and voltage just gives you a kick

So the old saying "it's mils that kills and volts that jolts" And DC is alot safer than AC

[StinkyCheese9999]

@raypsi

Not really. Yes current is what flows but no it's not current that kills. A 24V, 1000 amp circuit is safe to bridge with your arms. A 1000 volt, 25mA circuit may kill you.

[whitesideentp]

@StinkyCheese9999 You have it completely backwards. It's current that kills... not voltage. Think of the plasma balls that make your hair stand on it's end. They have like hundreds of thousands of volts.... but the amps are minuscule. A 24 volt 1000 amp circuit will kill you quick!!!

[StinkyCheese9999]

@whitesideentp

Wrong. The voltage has to be high enough to make current flow across your body.

So in truth it is both the current and the voltage but far more the voltage relative to levels we often see.

For example, 220V and only 20mA can kill you, but 24V and 1000A will not. 24V simply is not enough voltage to make much current flow across your body (heart) because the body has too high a resistance.  This is scientific fact (Ohm's law).

[whitesideentp]

@StinkyCheese9999 @StinkyCheese9999 Wrong! I have an associates degree in Electronics Engineering and I am here to tell you you are wrong. Just do a Google search dude.... the answer is there if you search amps kill not voltage. :)

[StinkyCheese9999]

@whitesideentp

You do not have any degree at all in anything relating to electronics engineering. LOL, you couldn't even pass electronics 101 in college without knowing that the current rating of a power supply is ONLY the max it is capable of, NOT how much flows through a resistance which is determined by the voltage. This is basic science that grade school kids can figure out.  Current kills but voltage determines amount of current flow so it is truer to say voltage kills.

[whitesideentp]

@StinkyCheese9999 You just agreed with me in the last sentence of this post. All I said is it's current that kills... not voltage. Its scientific fact and I'm willing to put my money where my mouth is. Are you? I doubt it unless you want to just hand me some free $. And how can you say I don't have a degree?. lmao. I'm a designer / manufacturer and have been designing and manufacturing my OWN electronics products for 8 years. Google "mini heat press" and then look site that has miniheatpress.

[whitesideentp]

@StinkyCheese9999 Since you are so smart and much more educated than me and have so much understanding of basic science. Why don't you use your smarts and Google "whats kills voltage or current". Either me, Google and the rest of the other websites are wrong or you can't just admit to being wrong. Nothing wrong with being wrong. You just make yourself look bad when you argue with a fact, not an opinion. Do some research!

[StinkyCheese9999]

@whitesideentp

Apparently you haven't the education in electronics that I do. Let me pose this very simply one last time, draw upon your own observations in life and tell me which is more dangerous:

Holding two AA NiMH batteries, which are 1.2V (nominal, or 2.4V in series) capable of 10A current in parallel,

OR

Sticking two nails in an AC outlet which is 110V, if it has a 10A breaker on it?

Obviously with current the same, the former is dangerous and the latter isn't. THINK

[StinkyCheese9999]

@StinkyCheese9999

lol, I MEANT the latter is more dangerous. Must sleep in longer on the weekends.

[whitesideentp]

@StinkyCheese9999 @StinkyCheese9999 And I just re-read your example. You stated that 20 mA can kill. A milli amp is smaller than an amp. My cell phone charger is one amp. It won't kill me. And you also said that 1000A will not kill which is absolutely false. It will kill fatser than you can blink. My house circuit breaker trips at 30A. I couldn't imagine a 1000 amp circuit.

[StinkyCheese9999]

@whitesideentp

You don't understand electricity. Your body is a resistance. Suppose a resistance of 10,000 ohms. Ohms law is V=I/R, voltage=current/resistance.

Now, suppose a 24V, 1000A power supply. It doesn't matter that it's "capable" of 1000A, the voltage is what determines how much current will actually flow through a resistance (your body), again this is ohm's law. So 24V/10,000 Ohms = 0.0024A or 2.4mA, not dangerous

Now suppose a 220V, 50mA PSU 220V/10000ohms=22mA

[whitesideentp]

@StinkyCheese9999 I'm not saying all this to be argumentative or a know it all. I actually find what you are doing intriguing. I just think that giving false information like that can lead someone astray and possibly cause harm or death.

[StinkyCheese9999]

@whitesideentp

You may mean well but are factually wrong. The voltage has to be high enough to make current flow across the body while the amperage rating of the circuit only has to be equal to or higher than a lethal level. ie - a few dozen mA

400V / 30mA is more dangerous than 24V/1000A.

Here's an example, you would say that a 24V, 10A circuit is dangerous. I use those often to build audio amps and can touch 24V with no issues but a 110V/10A wall outlet is very dangerous

[narcovice]

heat and bad roads does that res mines blew up

[narcovice]

electric bikes dont have gas only battery and tires wear out fast at that speed and blow up and force uncontroled turns

[Fentanyl3]

Road bikes can easily be pedaled up to 40MPH, so your telling me the 5 more MPH can destroy them? Nah, try again later

[mary2al]

Did I miss something or did you NOT show the bike and its type and configuration at all?

[analyzingfunny]

broke some speed limits there. funny. What battery system are you using and how long will it driving it like that? Thank you.

[narcovice]

why did you say ran out of gas if its electric and does it ruin your tires at fast or any speed

[MoPar7055]

No why would it?

[tpulley]

that looks like cape coral, maybe somewhere else in florida

[Kormiku]

I cant believe you kept me so interested in such a long movie. The scenery was beautiful and your commentary kept me hooked. More videos like this but going faster please!

[lockpickman]

hmm... 600 4 electric kit...150 for gas kit... so hard to decide...lol

[CoWolArc]

I've got a gas bike right now... But I'm going to do an electric soon. It has advantages.

For instance, I'll be moving to a new apartment soon where I'll need to keep my bike inside to prevent theft... A gas bike would smell the whole place up!

[iakazul]

Good job.

[packagewarren]

damn dude, awesome! when you were going 30 mph at 15 amps, was that 15 amps from the controller or the motor? that was cool and scary as well by going on that bad pavement. but i gave you an "awesome" rating. good job.

[packagewarren]

wow!mow much for the motor? does more volts and amps mean more speed or longer distance or both?...great work also where can i get a volt/amp meter for the bike?

[thebestofall007]

awesome bike!!! it looks like it needs shock absorbers though based on how much that camera was shaking when doing 45 (id feel sorry for anyone who hits a pothole on that bike; a lot of wear and tear on the crotch and legs/arms :( ).

[smartkart]

When riding a bike on even the smoothest roads, cameras always shake.

[energyindependant]

That was amazing, I really wanna convert my bike to this! No more traffic jams, goodbye exorbitant fuel costs, traffic wardens,car tax, insurance. This is the way to go!

[FossilizedArt]

Very awesome video. I'd be interested to know where you got your 24lb hub motor, and how much it was. I'm considering adding an E-hub motor to my Schwinn Stingray Spoiler's rear wheel.

Again, awesome vid!

[adamant1111]

u have a schwinn stingray spoiler awesome ive got one too

[richystar2001]

There's downhill mountain bikes that can easily take 70mph...and they do it on gravel surface.

[Dershnof]

I have been upwards of 80mph on mine..on a smooth surface.

[luc59457]

Click my name to see the first 120v ac e-bike of its size! First time you'll see a motor like this on an e-bike. Something unique for once.

[Peddobjoernen]

This stuff without a disc brake would be suicide, otherwise it looks pretty awesome.

I don't want one though. (I'm lying)

[OLNoire]

Rim brakes are disc brakes too, and they actually have larger diameter discs than normal disc brakes...

[Peddobjoernen]

Except they melt at high speeds, and have 1/10th the stopping power and none of the smooth stopping power... Sure.. You know what I meant.

[edwin00420]

um, thanks captain safety, im pretty sure any motor you buy will have sufficient warning, i had no idea we needed a warning for the video. wow i almost thought about going fast, but you have saved my life. that was close...

[PunkMartyr]

Holy sht thats fast for a bicycle

[luc59457]

This is a pure lie to attract attention all. I made my own e-bike and it goes 45 KILOMETERS an hour. I have went 60km/h down hill and my front started to shake. I have very good suspension too, I could hit huge potholes at full speed. His claim is 72km/h which is faster than a gas scooter. Most people are dumb, it's not 110km/h! 72 is still a joke on a pedal frame. I went 60 downhill and I know how it feels, not 72km! OH and u can see my speedometer!

[jojo808]

me and a buddy been over 60mph on an old Peugeot downhill on the Pali hwy, at that speed you just glide over potholes with a little lift. The bikes help up fine. Not sure why you think he would lie for attention.

[HOPPERFZR]

i beleive the video over your nasty opinion

[eRustler]

I have this same motor on the rear of my bike, and you are wrong. At 48V, and 60lbs of batteries, I get a top speed of 42mph on flat pavement. He's running 72v, with a lot lighter batteries. 45mph isn't an exaggeration, it should actually go faster with thinner tires. Does being a troll make you feel older than 11?

[ortcloud99]

90% of that footage could have been edited out, I would like to hear more about the bike first, show us the bike, tell us about the setup, what kind of batteries etc. then show us the last two minutes of the 45mph blast with the speedo in the shot so we can see it and dont have to hear you calling it out.

[analyzingfunny]

re you peddleing as well?

[analyzingfunny]

This is beautiful.

[RaphaelJeger]

Cool. The motor seems to be really noisy - is it just the video or does it really sound like that?

[Andrejboskov]

Hub motors use only one gear so they're designed to run at very high rpms, usually 6000+ which is more than most car engines can handle. My e-bike uses the bicycle's gearing so I can't speak from personal experience, but my guess is that a tuned hub motor going 50+ kph is going to make A LOT of noise.

[vladimir2277]

What's the range?

[2Shye]

I doubt your frame and breaks are going to be able handle such speeds for long.

[Andrejboskov]

Actually once you cut the power, e-bikes can slow down pretty quickly from high speeds on their own without braking due to their extremely high drag coefficient.

[Andrejboskov]

Unless your bike is made out of plastic, speed isn't going to break the frame. Think about it; a lot of people who go on vacations attach their bikes to the roof of a car. I've seen cars on the highways going 110 kph or more with bike racks and the bikes don't break.

[2Shye]

no but if you hit a pot hole at 110 kph your going to snap a hell of a lot of spokes.. aswell as possibly breaking your front forks if they are suspension forks..

not to mention getting a sore ass.

bikes don't have the kind of suspension to handle bumps at such high speeds..

[Dershnof]

I have a Trek 7600 with full suspension and about 7 inches of travel on the front and 5 inches in the middle, and I hit a realitivley large pothole going 41mph..diidnt really seem to hurt it much. I took it in the same day to the bicycle shop, they checked it out and they did not find any damage whatsoever to it, so it really depends on the type of bike u have and the quality of the parts.

[StinkyCheese9999]

@Dershnof

You're overlooking that it has lots to do with the depth and shape of the edge of the pothole, though others are overlooking that faster doesn't always mean worse, if going fast enough on a short enough pothole then the wheel doesn't have time to drop all the way to the bottom of it, or in other cases at just the right speed it can bounce back up a little making less weight on that wheel when it hits the pothole edge... combined with different rim strength, tire size & inflation

[Dershnof]

Yeah your right. I have a Schwin Ranger 2.0 and it has only 3 inches of front suspension travel. I have hit potholes at only 15mph and they bottom out sometimes. Now if I hit a pothole at 45mph it would totally be destroyed..unless you have at least 6-7 inches of travel.

[Dershnof]

Umm okay there is a diffrence here bud. The bike racks carry the bike above ground..theyre not traveling on the ground where it would be a world's diffrence.

[StinkyCheese9999]

@Andrejboskov

That has nothing to do with anything. It's not the wind resistance that causes frame breakage, it's the stresses of the weight of the rider, the irregularities on the road, and the torque of the engine. Bikes are overbuilt for handling pedaling stress and normal speeds, but not so much overbuilt that going 45 on a regular basis can be assumed safe. Overbuillding too much adds weight that is very undesirable when pedaling, and yet some still do break theirs with only pedal power

i wonder when one of these 80lb bikes going at 25 mph are going to hit a child on a pathway. when it does wave buy buy to no insurance no helmet etc etc they may even ban them altogether and ruin things for everyone else

[Calamarhi]

Man. I wish I would have had a speedometer on my Raleigh mountain bike about 6 years ago.. I had to have been doing 95 or 100 kilometers per hour going down a long steep hill on one of the back roads where I used to live. It felt like the tires were going to fly off. haha. I don't think I'll ever do that again. =O

[Dershnof]

I know. I have been 72mph going downhill in SF where I live. It really does feel like the wheels are going to just fly off. But its a cool feeling though.

[TimpBizkit]

Where do you have such steep hills? I have one in Bath and I top out around 40mph. There are cars parked on the sides of the road and I don't trust that no one will pull out in front of me.

[suum52]

where'd you get 72V 35A controller? Price?

[jojomascalero]

excuse me, but the speed limit is 30 on that street....check it at 1:59.

shame on you!!!

also wouldn't some sort of disk brake retrofit would be better with these speeds?

Good job :)

[Omega92]

haha man that is amazing, better be careful though, you were at 45mph on a bike, one slip and youre gonna take one hell of a tumble.

[Dershnof]

I have been 57mph going downhill and through some sharp curves at over 40..just depends on how good tires you have

[1967jrewing]

Anything over 30mph/50kmh on a standard mountain bike and you're asking for some serious road rash!

I use a 48v 1000w currie drive on my bike and it's all I can handle safely. Be careful!!

[jojo808]

serious? i agree 45 is asking for it but the legal limit is our states is only 20, so most of the manufacturers are limiting the motors assist to 20. Their just dieing for us to keep using gas IMHO. Any semi advanced rider can do 25mph without a motor, but with the added weight of battery and motor I think that is ironically much harder since the most motors shut off at 20.

[URMILF]

Man! that's incredible. I have a Hummer bike and would like to get this for my bike as a project. Where can I purchase this product?

[rivalta]

can u tell me how much it cost all off this

[fuzzymonkey777]

Wow, What a dangerous game you play. I can think of so many things that could go wrong doing that. You be careful.

[DeeL2003]

great vid, you got balls of steel! Have you considered joing the V is for Voltage forum, I know there are alot of folks, including me, who would enjoy reading about your experiences with E bikes and your current project.

[knoxieman]

i'm worried that your going to have a real problem, I would really think about a good steel fork and if you find the ride is harsh I would also get a good steel frame as it will flex and give you a much better ride.

Please be very careful 45mph on a normal MTB on roads is fast and the strain it puts on the bike and the components maybe more than you realise!

Knoxie

[ampaynz1]

One side came with a torque arm, which fit this fork perfectly and was twisted tight with the motor and then tightened. So that any movement of the torque arm would also move the motor. Now I placed the large wrench with circle side on the very tight nut and

this was hose clamped to the upper fork in several places. Even if motor wanted to spin lose the wrench would tighten.

[ampaynz1]

The fork was too small so I bought a stretcher device and put between spokes on tire. It was attached to frame via thick two straps. I then used all my force to spread the fork until the motor would fit. The dropout had to be bent just a tiny bit equally on both

sides and two washers place between the motor and fork. I then went and bought a large 24mm wrench (maybe a different size) and tightend both sides as tight as humanly possible.

[ampaynz1]

When I first got the motor I was a little worried about the fork snapping as evsolutions pointed this out to me. I tried riding without a suspension and it felt very rough after a certain speed. To get the motor to fit in the fork took a long long time. Reason why is this suspension fork is made of steel. I paid $50 for the bicycle during one of those after thanksgiving sales at walmart at 6AM in late 2005. Magnets do stick to this fork.

[wcrider2]

hope your fork isn't aluminum!!

(if a magnet doesn't stick to it, it is!)

my fork snapped at the dropouts with an x5...

I ended up using a custom made steel fork, as steel is orders of magnitude stronger than aluminum.

very very dangerous with an aluminum fork!

[knoxieman]

Hello

Great video some amazing speed however unless I am wrong you are running this on a suspension fork? oops that's bad with an X5, I can send you photos of drop outs that have snapped of both sides at 5mph, I would recommend a solid steel fork of good quality, a torque arm and a full face crash helmet.

Thanks for posting though great footage, take care with great power comes great responsibility!

Cheers
