For those who dont understand; the ratio of miles per hour to kilometers per hour is 1 mile=1.6 kilometers. By riding 29 inch wheels and having the speed sensor think it is an 18 inch wheel the ratio is 29/18 or 1.6. Therefore the spedometer is showing KMH in the equiavalence of MPH. This works because the speedsensor works on wheel diameter. If the wheel diameter is smaller, then the wheel will need to turn faster to go the same linear speed as a big wheel. An 18 inch wheel is 1.6 times smaller than a 29 inch wheel and 1 km is 1.6 times smaller than a mile. By changing both parameters on the e-bike computer, it is still showing MPH equivalence. Simply put, this guy is brilliant!!!! Thanks for sharing this tip!
Pibbles 'n Bits Thank you I was tired already when I found this video and I've made myself angry trying to do the simple math. 40 yrs, old & I almost threw a tantrum like a child. Thanks for not being the apparent idiot I am.
This is a brilliant hack and a really smart way to "trick" the speed limiter. I wish there would be another way to hack into the screen firmware to remove the 30mph or 50kph limit
@@guywithjeep I've seen many video about people reprogramming the Bafang settings. And the max speed was 40kph. Do you mean with your display, the speed limit goes up to 99kph ?
Maybe btter when ordering to get the C965 controller. According to manual it can be set to higher speed limit: "9.3 Speed limit set: The location of speed displays speed limit value, the default value is 27km/h. Press UP/DOWN buttons to modify the value; the value can be set from 12 to 60km/h. Press POWER button to confirm when you finish the adjustment."
I got the bafang USB cable and programmed each mode. If I remember correctly I also changed to top speed to 99 kph, so basically removed the speed limitation without changing the wheel size. I set mine up as follows, 1 = 0 assist, 2 = 25%, 3 = 50%, 4 = 75%, 5 = 100%.
@@_el.guapo_ I think they mean they programed their controller and then also set the limit on advanced settings of the display. I've got the 850C display and my speed limit is 99 I think. The only reference to speed limit on the software is the throttle limit. There are also 9 assist levels in the software not 5 the OP mentioned (although maybe OP means levels 1,3,5,7,9 if they only have 5 levels on their display)
@@mixerfistit5522 I believe you can set a speed limit up to 99kph from the C500 display. But there is a speed limit parameter in the interface of the software (which you can connect with the USB cable) too which can be set up to 40kph. So I'm wondering does the display speed limit setting override the software speed limit setting? Anyway the wheel size trick would do.
There was no limiter on my bbs02b no matter what speed limit i set. I just set it to 99k originally so it was out of the way but even setting to 25k or lower nothing happened. As you have an 11 tooth the 48 or 46 tooth chainring will get you similar top speed and the 40 cassette will still climb well.
Yeah my top speed is only limited by the gearing , I have 20 inch tires and a 52T front sprocket and an 11 rear tooth sprocket. I get about 36 mph on a flat road. My Motor never cuts out , save for when the battery is dead. The latest BBS02 has that option to unlock the speed limit to 99kph
@@TheAgentAssassin I did find there was a limiter but it was only for pedal assist and not the throttle. I can't think of a time I'll be doing 99 km/h and need the motor assist.
I use P850C , i think i don't have that issue. 29er 44T front 8 gears back, 46.4mph and just spinning, i notice litle cut offs , when i ride on mode 9 but on gear 3,4 or 5. Then i just reach the limit for that sprocket , cut for 1-2sec then come back again. Probably hit the top rpm for the motor.
I have the HD & 850 c,42t & 11t out back,lifting the tire & flooring it,I get only 32mph,full pedal applying both or just 1 I only get 30 mph,I have a 29er
iv seen people say That it won't reach that top speed and tbh it won't by itself or on a flat or up hill but the fact that it won't restrict you once you reach 30mph this means that it will still provide a level of assist.
Little info on bafang mid drive check out wild timez in my second build. Cannondale trail 5 hardtail to trance 2 full suspesion. Best way to run mid rive is by the pas. Then you use the throttle only to maintain speed. If you use only throttle its slower and kills battery. I stay in 678 pas 9 for speed time. It goes 34.5 mph. no hacks yet.
You need to 3 things, a BCD 104 adapter for the BBS-02 from a place like superscooterstore, a Race face narrow wide 38t, and some single speed chainring bolts.
Ah, I see. I was hoping there were smaller chain rings available without any extra parts :) I have an internal gear rear hub, so it's either use that adapter and stick with 38T, or go with the 44T (or bigger) and add a few links to the chain. Maybe adding links is easier to start with :) Relatively flat where I live, so torque won't be an issue anyway. Thanks for that.
Hi bud I know this is an old video but I'm wanting to know what the actual top speed you got under load? I get that this will be dependent on different factors but what did you get? And with what battery? Thanks
@@FastJohnny80 Why so slow? 52vs can make a bafang motor reach 5 mph. Mine is only 11ah and 48 volts and I have reached 39 mph on flat road with wind. I am only 120 pounds and 5 8

Ive just got my 750 one and and thinking i need to get a smaller tooth to enable hillclimbing better, thanks for the tip!
The 32t that was on that bike was pretty great for off road use. It topped out at about 30 mph off road, but still had tons of low gears for technical stuff and climbs.
John,Nice Vid. Some folks in this world are as thick as pig shit as we say here in the uk LOL.What is so hard to understand in this video!!!!!If they cant understand this they are unfit to ride a bike and should only walk accompanied by a responsible adult.
Vegan Mountain Goat lunacycle has a 104 adapter for the Bbs02. That bike has really long chain stays which negate some of the bad chain line. It was fine.
I should have went with that one I got a cheep one from china Its solid but the center of the plate is to thin and the taps for the chain ring to mount are to thick so I Had to use shims Seams good for now. we set up a bbs02 on a 29" Hard tail for my dad to inspire him to get out side more and drink less beers lol so far it has worked he loves it..
Vegan Mountain Goat that’s awesome. Are you using a 30 or 32? The teeth end up really close to the spider. If you use a 34T it’s big enough that you won’t need shims. Happy trails
at the Moment his Bike has a 40t for now. but I'm thinking of putting a 34t for when he wants to go mountain biking in the hills with me. and yes I have thought of that with the smaller chain rings interfering with the Spider.. but my problem is that the chainring its self rubs the gear cover of the Mid drive system/bbs02 and I had to use shims/washers on the 5 4mm bolts that mount the chainring on to the bbs02
Vegan Mountain Goat Oh ya I had to use those too. Forgot all about that. 2 little washers on each bolt. You can bolt the chainring to the outside of the spider to get rid of that issue, but bolt spacers give you the better chain line. Another trick you can do is bolt a 32 on the inside and a 40 on the outside. Then bolt the 3 speed front derailleur back on and set it up to shift between 2 & 3, and lock out 1st with the low limit screw. Then you have road and trail gears up front.
i will try this soon as i can with my small 250 watts motor i just hope i can set the wheel size to 18 inch .best thing you can do to proof what your talking about is do a mileage test same starting point lets say a 5 mile run ,then do your hack and see if the mileage readout the same if its close god dam it you be right give are take
nope that want work sorry but it can if you put a different speedo side by side it a be a intresting result i no what your doing is fooling the controller ;)
How do you get that speed with a tiny little front chainring. The 44t stock is high geared and lucky to hit 20?, just ordered the 48t. You must be running the pas level 9 flat out with no weight. Once sat on your seat and your body weight will take 7mph down. Trying to get mine to do 28mph and be happy there.
Vince62965 this is an old video. That display only goes up to 50km/h in the programming. We made our own programming cable years ago so program the Bafang. Settings are up to 50km/h or “by displays command”
It's the wheel size that's important here, not the number of cogs on the cassette. For 26" wheels you want to set the wheel size to 16", or 16.25" if you can.
Hi, I have a stupid question about reprogramming the Bafang BBS02 motor. I don't want to increase the speed of the motor, the only think I want to do is lower its effect from 500W to 250W, since that is the legal restriction in Sweden. Could you help me change this by giving me advice on how to do it I would very much appreciate it. Thanks!
you can set the speed limit to your choice, cause it s not the watts that matter, it s the top speed, and if you program it to be undervolted to 250w you might still get a ticket because it s written 500w on it...
@@greceanumihail They have an e-bike speed restriction in Europe, as well as a Watt restriction. Canada has a 500w restriction. United States has a 750w restriction. Any higher, then you are not e-bike legal. You then have to register the bike as a moped, or whatever your local laws require as a motor vehicle.
hah I rented an ebike over the summer and seeing the power cutoff was at such a slow speed, (in france its 25 kmh or 15,5 mph) my first thought was to change the wheel size...wasn't sure it would work but seeing this ; ) so does the battery dies really quick when going like 20 mph? I'm really curious great video thanks!
I wander if you change to assist level 5, what is your max? Many people show how fast they go under assist level 1 or 2....but that is the low power output condition.........not the true max of this BMS After you modify it, I wander what is the real max of your BMS when under highest assist level............. well....the way you change will also give you wrong distance reading. By setting to 18" wheel, the computer think you rides shorter distance as the circumference is shorter as well, per rotate goes less distance.
That's a really good tip that I have not thought of. I'm working on a BBSHD build on a 2013 Trek Marlin and have been thinking about chain alignment so that I can use all my gears.
Joshua Smith You should be fine with the Marlin. Put the whole build together and deal with issues as they come up. I've had 3 ebikes and 0 chain alignment issues.
I have the bbshd 1x10 with a SRAM XO GRIP SHIFT and my chain has not jumped off yet at any speed. And believe me I can shift those gears quick from high to low or Vice versa with just a slight pull on my brakes (just slightly enough not to engage) PS I have taken mines up to 50MPH on flats with a 14c (58.8v) battery
Now show me how I can get more hill climbing power in 1st gear? so many ridiculously steep hills around me. like my driveway, which is the worst because I have to start climbing it at zero miles per hour.
I can't see how that's possible if you're control box is working out the speed from the wheel circumference you've entered. someone please talk me through the parameters if you've entered dimensions that are much more smaller than the wheel you have, it would go faster but the read out on you're display would be wrong. ie distance traveled, speed etc etc.
I tried to explain this in the video. Here's another explanation. 29 kmh = 18 mph. So if you set your 29 inch wheel to an 18 inch in the setup menu, and then change your display from miles to kmh, the display will show your real speed. It will just be in mph not the kmh shown.
The computer knows how many times a certain rim size needs to be spun in order to reach a certain mph. Smaller rims need to spin faster to reach the same mph of a larger rim. If you lie about your rim size then it will think your rim is small and need to be spun faster to reach the mph. You use the ratio offset of mph to kph only because you can take advantage of the kmh settings in the display. You just have to find the right sized wheel that will accommodate that difference. Kmh is .62 higher than mph, so lie to the computer and tell it that you need a .62 head-start, and you lie by putting in a smaller wheel size. Example for determining your new wheel setting: NewRimSize = (30MPH * OrigRimSize) / 48.28032km.
So is this just tricking the sensor into thinking it's going faster but it's really gaining no speed irl. Or is the hike actually gonna get faster because of this
I think o should have taken more Physics Classes at School in the 70's has I still think I'm correct, but it's only a bike so I'd prefer to differ. 😁 Happy Cycling.
With far less torque . I had a Bafang and a hub motor (made by Cute - I know it's a stupid name) and the Cute had far more torque . With mid drive you can mess with the chainrings to get better acceleration or higher speeds etc but you cannot beat a hub motor for torque . When I say hub motor I mean rear drive not front drive . I ended up ditching the Bafang .
The hubs that are powerful you can barely pedal, mid-drive remains a bicycle. Anything more powerful than a Golden Motor Smart Pie is shit for pedalling.
But that is my point . Both my Bafang and hub motors were 750W . The hub motor was far more powerful . I agree with you on the pedaling part but then i just put the bike into low setting . I also think hub motors look far nicer on the bike . Clean looking and they blend in with the drivetrain .
Have you seen the speeds of electric model airplanes - those motors are FFAAASSTT and strong.. Now, you don't have to worry about a dog chasing you, or people on foot :-)
Sorry mine showed 67kph with no load once before I changed the gears, now I have a cassette with 11,36 I can pedal easily at 32mph so I'll buy a 46t next month and it won't draw too much on battery. With the 44t I was only getting 18mph but didn't have the 11,36 cassette. But took some time to find the sweet spot of the 46t. Will change back the 44t just to see the speed etc
Still fast lol had some driver's followed me for a while and commented on the speed lol, one guy shouting out 32mph mate an not seen a bike this fast... Dont know if there Good for long periods of time at that speed, I set mine up to 28mph and still goes 32mph
sixstanger00 Nice. I have a problem and will admit it. I'm always happy with what I got, but what would it be like with just one more cell.... After a summer of that I'm up from 12s to 20s lol. Think I'm reaching the limit of the poor motor though.
Hold the + - buttons down till it's in menu,then hit the power button 8times while still holding + - down.setting wheel size higher will make it go faster,I have mine at 32in and it goes 38-40mph in the right weather. I don't go much higher I worry about frying the controller.
Lol. I know this is sarcasm, but I've hit 65 mph on my 8KW bike. This is an OLD video and if I remember right I just wanted to get rid of that "bouncing off the rev llimiter" feeling around 32 mph.
I'm happy with 30 my dude I'm just saying I need to be in my smallest gear to do it I can do 37 on the streets that I ride on in my city downhill source no ebike
Changing the tire size on the dashboard does nothing to your speed, its just thinking about the wheel spinning, theres a difference between your rim spinning an actual movement speed, your dashboard can say you are going 30 mph, but if you use a GPS on your phone, the gps could say 50 mph because its an object moving forward, not a spinning rim which makes no distance,
Now you're display won't be showing the correct speed, Mileage Done & all the other things that the Display is for. 20 miles an hour is fast enough for a road bike, if you want too go faster just buy a motor cycle, I bought the BBS02 500W Kit with a 36V 15AH Battery & put it onto my Carerra Subway, I went out yesterday for the first time & i am satisfied with the way it performed, it don't half make you Grin as well, A lot more easier than pedaling like crazy & breaking into a sweat.
He is not increasing the power. He previously only had full power available uphill at a low gear. Now he has it whenever he likes. No additional strain on the system would happen.

Strawberry is a good snack
Brilliant!
interesting, do you think this will work on the BBSHD?
hah I rented an ebike over the summer and seeing the power cutoff was at such a slow speed, (in france its 25 kmh or 15,5 mph) my first thought was to change the wheel size...wasn't sure it would work but seeing this ; ) so does the battery dies really quick when going like 20 mph? I'm really curious great video thanks!
Philibert Rousseau We'll it's got a 20 mile range if I go flat out. So at 20 mph cruising probably 30 plus miles.
John Stowe wow thats sick
Why did you sell it ?!!!
Seb K rented
Philibert Rousseau Srry that question was directed at John .
Good show mate,
Will this work on a rear hub motor; "m2s all terrain?
um did u realize that you’re peddle assist was at level 1 the whole time put it on 9 and see those rpm go faster
he was using the throttle. it 100% overrides the pas
Lmao this guy is smart
@@HighVoltageKits on mine the throttle scaled with pas so the range of power and rpm was greater on pas 5/5
Thats with no load so you will lose 7 mph or so
I wander if you change to assist level 5, what is your max?
Many people show how fast they go under assist level 1 or 2....but that is the low power output condition.........not the true max of this BMS
After you modify it, I wander what is the real max of your BMS when under highest assist level............. well....the way you change will also give you wrong distance reading. By setting to 18" wheel, the computer think you rides shorter distance as the circumference is shorter as well, per rotate goes less distance.
It looks like you have nice chain alignment and no guide. Do you have any problems with the chain jumping?
Joshua Smith No it stays on all the time. narrow wide and a clutched derailleur are key.
That's a really good tip that I have not thought of. I'm working on a BBSHD build on a 2013 Trek Marlin and have been thinking about chain alignment so that I can use all my gears.
Joshua Smith You should be fine with the Marlin. Put the whole build together and deal with issues as they come up. I've had 3 ebikes and 0 chain alignment issues.
I have the bbshd 1x10 with a SRAM XO GRIP SHIFT and my chain has not jumped off yet at any speed. And believe me I can shift those gears quick from high to low or Vice versa with just a slight pull on my brakes (just slightly enough not to engage) PS I have taken mines up to 50MPH on flats with a 14c (58.8v) battery
Now show me how I can get more hill climbing power in 1st gear? so many ridiculously steep hills around me. like my driveway, which is the worst because I have to start climbing it at zero miles per hour.
Get a smaller chainring or a wider range cassette or both.
It does not work for my bafang 500 watt rear hub motor :(
Just noticed his front fork is on backwards lol
Nope. Manitou has flipped crowns. Both brakes are on the same side and wouldn’t be if it was backwards. Lol, noob.
how many watts and volts your motor you have?
52 Volts 750 Watts
@@FastJohnny80That's kind of not impressive. Mine is 48 volts and is 1000 watts
I can't see how that's possible if you're control box is working out the speed from the wheel
circumference you've entered. someone please talk me through the parameters if you've entered dimensions that are much more smaller than the wheel you have, it would go faster but the read out on you're display would be wrong. ie distance traveled, speed etc etc.
I tried to explain this in the video. Here's another explanation. 29 kmh = 18 mph. So if you set your 29 inch wheel to an 18 inch in the setup menu, and then change your display from miles to kmh, the display will show your real speed. It will just be in mph not the kmh shown.
The computer knows how many times a certain rim size needs to be spun in order to reach a certain mph. Smaller rims need to spin faster to reach the same mph of a larger rim. If you lie about your rim size then it will think your rim is small and need to be spun faster to reach the mph. You use the ratio offset of mph to kph only because you can take advantage of the kmh settings in the display. You just have to find the right sized wheel that will accommodate that difference. Kmh is .62 higher than mph, so lie to the computer and tell it that you need a .62 head-start, and you lie by putting in a smaller wheel size. Example for determining your new wheel setting:
NewRimSize = (30MPH * OrigRimSize) / 48.28032km.
Well I feel like I HALF WAY understand it, but I'm going to attempt doing it anyway.... cuz I want to go 4 miles faster
🛀🤺
how many teeth on your chain ring of the motor?
I tried on my rear hub 750 w from OZO...it doesnt works ,it cut even before...
So is this just tricking the sensor into thinking it's going faster but it's really gaining no speed irl. Or is the hike actually gonna get faster because of this
It's gonna gain top speed because of the derestriction, unless it can't reach the restricted speed in the first place.
my bike is a 26inch wheel so what shall I change the wheel size to and the Kilometres will it work on my 500c display
26 / 5 X 3 = 15.6"
Can’t find a way to send private message. Want to ask about changing tire size on my Raleigh Cadent.
I'm not that great with road bike tires. What are you trying to do?
I want to hack my controller like you did to make my experience better. Can’t figure out how to set the tire size
@@waynehager1389 Is it a BBS-02 or BBS-HD, and if so which Display does it have?
John Stowe I don’t know the answer. Just says Currie Electro Drive
Great video. Thanks.
Can anyone tell me how I can access my set up menu on my VR-01 FREEWAY E BIKE ? Any comments would be appreciated.
Well this work for my max cargo eunorau ebike?
hello John
please help me to get to dillenger display menu I try 1919 but don't work
No experience with that kit
Try 0512 worked for me
what kind of repair stand is that?
Cheap Amazon stand I picked up back in the day. It was maybe $50.
I know some ask silly things but you cant be aresed to reply to some .
On a 26 inch it wont give gen speed like 29''
난 또 뭔가 했네... 멍청한건가.. 바퀴 인치를 낮추면 표기된 숫자만 높게나오지 정작 rpm수가 달라서 (18인치와 27.5인치와 직경을 생각만해도 답 나옴) 디스플레이 속도만 뻥튀기 되는거지 실제 속도는 똑같음 ㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋㅋ
vfbank yeah what you said. I agree
I think o should have taken more Physics Classes at School in the 70's has I still think I'm correct, but it's only a bike so I'd prefer to differ. 😁 Happy Cycling.
I've tried it, it works. There's no difference in opinion when it comes to math.
Happy Cycling Stephen
I dont even have that ebike anymore!
+John Stowe Only had mine 3 days got 8 mile on the clock, & I won't be reducing my wheel size. nice video though. 🚴
but how can you hack you didn't tell us anything u just showed us the bike!
awesome!
Apparently this will go twice as far as a hub wheel motor on the same battery : )
With far less torque . I had a Bafang and a hub motor (made by Cute - I know it's a stupid name) and the Cute had far more torque . With mid drive you can mess with the chainrings to get better acceleration or higher speeds etc but you cannot beat a hub motor for torque . When I say hub motor I mean rear drive not front drive . I ended up ditching the Bafang .
Acceleration IS torque.
Mid-drives have the best torque everyone knows that.
I go up to 25 miles/hour up hills on a 48v battery.
The hubs that are powerful you can barely pedal, mid-drive remains a bicycle. Anything more powerful than a Golden Motor Smart Pie is shit for pedalling.
But that is my point . Both my Bafang and hub motors were 750W . The hub motor was far more powerful .
I agree with you on the pedaling part but then i just put the bike into low setting .
I also think hub motors look far nicer on the bike . Clean looking and they blend in with the drivetrain .
It's bafang 250w?
hi, i how i can max out speed limit on ewheels bam supreme?
I have tried that,and still doesn’t go any faster
can this tuning ruin the engine or battery overheating engine or battery
Have you seen the speeds of electric model airplanes - those motors are FFAAASSTT and strong.. Now, you don't have to worry about a dog chasing you, or people on foot :-)
They do 32mph an there's no load, so when all said and done it's still 30
Yea with no load mine shows 51 mph, but once I'm on it. Still top out at 31 mph.
Sorry mine showed 67kph with no load once before I changed the gears, now I have a cassette with 11,36 I can pedal easily at 32mph so I'll buy a 46t next month and it won't draw too much on battery.
With the 44t I was only getting 18mph but didn't have the 11,36 cassette. But took some time to find the sweet spot of the 46t.
Will change back the 44t just to see the speed etc
With that hack with load I don't think there's any difference in the top speed
Still fast lol had some driver's followed me for a while and commented on the speed lol, one guy shouting out 32mph mate an not seen a bike this fast... Dont know if there Good for long periods of time at that speed, I set mine up to 28mph and still goes 32mph
@@tonielcock8891 I'm running 11-34 and 44, I was thinking about upgrading to a 46 also. I can't use the 12 and 11.. sucks
Is it possible to go behond that speed?
I’m going to go ahead and dismiss this video as it’s 7 years old.
I’m getting a kit fitted and I’m sure it runs better than the one featured here.
What is max speed on this?
40mph
Nah it’s more like 32
Smart!
That's awesome
Can I do this with a wingbike if anyone could help me I’ll appreciate it
Can this hurt the motor?
Nope, as long as you don't over heat it by doing something stupid like trying to go up a steep hill slowly in your highest gear.
As long as the motor maintains a high rpm its happy
40 MPH on a MTB?
Good grammar, that's butt puckering fast!
70 kmh on My MTB
L3HM1 -
I've managed to hit 30 MPH on a short downhill, but only for a few seconds.
No hills tall enough in my area.
sixstanger00 I've hit 40 on a shitty mtb downhill with loose spokes. Scary shit.
joblessalex
I just set a new personal record today...32 MPH.
I was holding on so tight, I was pretty much part of the bike at that speed.
sixstanger00 Nice. I have a problem and will admit it. I'm always happy with what I got, but what would it be like with just one more cell.... After a summer of that I'm up from 12s to 20s lol. Think I'm reaching the limit of the poor motor though.
Thanx John - you're a genious!
Once i reached 45 mph on my bike
How do you access hidden menu
Hold the + - buttons down till it's in menu,then hit the power button 8times while still holding + - down.setting wheel size higher will make it go faster,I have mine at 32in and it goes 38-40mph in the right weather. I don't go much higher I worry about frying the controller.
@@jasonkoz8985 if setting the wheel size higher makes you go faster why did he set his to 18 much lower for more speed? I'm confused
Asked me a 4 digit code
i have error 30, can u help?
Or lucky I have a e bike it only gos 19 or 20 I wish it wood go 25 be perfect
Holy shït I hit 65mph on my 1000w bike
Lol. I know this is sarcasm, but I've hit 65 mph on my 8KW bike. This is an OLD video and if I remember right I just wanted to get rid of that "bouncing off the rev llimiter" feeling around 32 mph.
Hmm
wheres you battery mounted?
Marshall Thomas I had it inside a frame triangle bag. it's sitting behind the bike in the video
Like all bids, didn't show up how exactly..but shows u..look I did it! Sometimes I wonder why I waste my time on this!;/
ok
Great 👍 please could you let me know how to do this
I'm happy with 30 my dude I'm just saying I need to be in my smallest gear to do it I can do 37 on the streets that I ride on in my city downhill source no ebike
yes but not uphill
Not working with P850 if someone want's to try :D
Just reprogram it a special open source FW for the motor and the controller and every limit is removed and you can set it to whatever you want.
@@dtiydr nah man, 45 kmh is enough for me
👍...
Changing the tire size on the dashboard does nothing to your speed, its just thinking about the wheel spinning, theres a difference between your rim spinning an actual movement speed, your dashboard can say you are going 30 mph, but if you use a GPS on your phone, the gps could say 50 mph because its an object moving forward, not a spinning rim which makes no distance,
Now you're display won't be showing the correct speed, Mileage Done & all the other things that the Display is for. 20 miles an hour is fast enough for a road bike, if you want too go faster just buy a motor cycle, I bought the BBS02 500W Kit with a 36V 15AH Battery & put it onto my Carerra Subway, I went out yesterday for the first time & i am satisfied with the way it performed, it don't half make you Grin as well, A lot more easier than pedaling like crazy & breaking into a sweat.
It's still going to be accurate, but it's going to say KM when it's really miles.
accurate enough where even if it's very minor inaccuracy it doesn't really count. it's very close to accurate
I reached 47,8 on my mtb whit slick tires
Slowww
Clever. Thanks.
Don't do this. It will destroy your controller. The controller and motor is rated for a specific power, and 'hacking' the settings will damage them.
He is not increasing the power. He previously only had full power available uphill at a low gear. Now he has it whenever he likes. No additional strain on the system would happen.
That won't do anything mate, accept for giving you the wrong everything
Hopefully the smarter viewers can see how it works.
@@FastJohnny80 omg people are so fucking dumb sometimes, get this man a blackboard and some chalk so he can draw a diagram for the really stupid people that still don't understand. Paul.........I willlllll buyyyyyyy youuuuuuu sommmmmme crayyyyyyonsssss
30mph to 50km fake video :)
Nah, just another posted who didn't listen to the video and doesn't have the intellect to guess correctly. Well done.
km is the new MPH.
LOL! More "speed" hacks for lame bikes. I wish these stupid people could afford motorcycles so they wouldn't be giving bikes a bad name.
if you seat on the bike will be less speed adding your weight on the bike nice try to cheat the peoples
Didn't knew it was gear that depends haha
