Youngest son that I know of 😂 😘
😂😂
That look on his face at 10 minutes or so. I almost felt the dads pride you felt! He was happy for sure!! Well done dad!!!!
Hi dude! I'm an electrical engineer that came across a lot of motor controllers.
The capacitors they use are usually 55V capable, It won't have any problem on the most 48V controllers if you slightly overvolt it.
Mainly motors only have windings and a hall sensor, which should be alright uptil 90V's. It's gonna take all the load until it reaches 85°C. It's the controller you'd want to keep an eye at. That it might pop up!
Gread video! Cheers!
*Healthy advice: You should use pedal assist on front wheel to have an AWD bike and burn dem cals fo good!
*Also your tires have very high rolling resistance for a road like that
whens the wheelchair build coming ,disabled people are a market too and theyre sick of these 8mph chairs , i wanna see mr billings do 30 mph around morrisons getting his gin in quick time
😂😂😂😂
😁
i seen a wheelcheer e-bike, last week, in my town The Netherlands, just 1 front wheel build on it, was looking good. but not a hub wheel like this. i will film it when i see it again.
was more like this : ua-cam.com/video/fjLZPaCmlIc/v-deo.html
Truth what's the point of living till 100 if I can't drive a sporty mobility scooter
Well done , the smile on your son's face says it all .
Epic stuff dude, loved seeing lewis with that grin! Good on ya mate!:)
That was a really nice moment! Something else to keep in mind while riding ebikes are helmets, most people wear cpsc helmets, when they should be wearing nta helmets like xnito or bern hudson
Excellent. Your son obviously loved it
Great job Steve
Great work lads.
What more confirmation of a job well done from your son than that smile, Pukka mate.
Great work D.S 👍
from Australia
Love your content.
Great inspiring Upgrade. I’ve a cheap 24v 250w folder and have gone for changing the front hub to 350w and 36v battery not so much for extra speed but extract torque. I was to chicken to do what you’ve done. I’ve now been inspired to upgrade to 48v on the 350v as the next upgrade.
Why not 48v on the back 24v motor as well?
😂perfect, I was searching some feed back 350W. Thought it won't change much. 👍 Thanks, go for 500w now.
Will definitely 100% work as your Over volting it will make it go much faster but the hub wheel might get a little warm/hot 😂
Good stuff my man
Well Lewis is smiling and like always say to my Son as long as your happy I'm happy so the battery upgrade is a success 🙌 👌
great experiment, it means most of us on 36v could make that step-up to 48v with a battery and controller swap-out. You might want to try that gps app in a car just to see if the car speed lines up with the app. Thanks for sharing.
Dude Stuff doing Dad Stuff, nice to see!
It looked like he got all his Christmas at once with the smile he had. Well done for the great work you done on his bike. Keep the good work up .
That's a great idea to save a lot of weight instead of putting a big heavy motor , thanks !
You need to setup the kt controller properly to set how many magnet poles are in the hub for the speed. I wouldn't say this was a particularly long lasting setup with no torque arm and the planetary gears will get shagged in no time
Nice looking bike. Proper amazing in motion.
Brilliant upgrade
You're the 250w king!
These are the questions i have im trying to either buy my daughters a mini bike with controller motor and battery make it myself cant afford crazy prices tho love your channel m8 brill vids ...i also wanna up power to make a wheelie machine so i can have ago lmao
Try the P 2 setting 0-6 regarding your speed Steve, just pick the 1 that matches up to your GPS speed, this will definitely fix it
Good luck Daron
hi mate, in relation to the speedo being wrong check how many magnets the speed sensor has on the the front hub motor and then see if theres any settings option on the display to match it (it may say magnets or poles on the display) because that will deffo put your speedo out ;)
Well said I was thinking the same thing
On the Electric Bike Laboratory channel, they used a product called Statorade (manufactured by Grin) to transfer the heat of the motor to the casing. This appears to be an instance in which a product like that would be useful.
Great job
if ya goin slow up a hill turn the power to low. also theres an easy controller mod were you solder across 2 points and that stops the cut off. keep an eye on the wire temps
I like the setup,nice set of hydraulic 4pot brakes would do the trick,do you need to have the throttle on the bike,if not will it still go the same speed? 👍🏴🚴💥
Could you put a kit on an old but good CannonDale super v 400 ?
Great video, thanks for sharing ,,,,,,
You should upgrade the phase wires inside the motor for thicker wire
Have a look on eBay for heat shrink solder connection. You just slide it over the wires and hit it with a heat gun
You can always get a second hand garmin satnav and fit on the handlebars to get your correct speed.
you can drill the sides of the hub motors so they cool properly. direct drive hub motors can be majorly overdriven if you cool them. grin technologies cover this in great detail on their youtube. i have two crazy ebikes with drilled direct drive hub motors they never over heat. if you overheat the hub motor it will break .
dont know anything about geared motors. but direct drive motors are the dogs bollox for overdriving them
Thank you mate. Can you give us more details on how?
Brakes upgrade , mech. disc or Hydros if you continue on with the BEAST,
Speed plus weight and no suspension equals scary for you, add FAT tires, rear motor and dual batteries Helmet, gloves, proper anti -road rash attire. Looks like an additional 1,500 pounds or USD? Assuming your son bought a 5oo.oo battery, 2 k at the moment.
Excellent content, enjoyed watching your son hold the display kit while sitting, in such a manner to not be blamed for anything BAD, hahahahaha my son does the same,
For the Speedo I’ve seen this about you need to tell the controller how many Magnets and in the hub
Great parenting..best wishes.
Thanks for this vid. Dude, could you do a video on your thoughts about chainless bikes? Are they worth it? It's hard to find out anything about them.
Thanks I've never tried one yet!
Some display controllers have an option in the settings to set wheel size, in case it's wrong. It might also let you switch between kph and mph; what I'd consider if it seems way off for the tire size. Otherwise you can petition for anyone who knows how to calculate speed based on motion in the video.
Nice upgrade Steve, your son looked well pleased 👍👍
I'd for sure get him a middrive as a front drive is more squirrelly and if he is on mud and gravel face plant
ive run a sabvoton svmc7245 with 250watt bafang hub motor thats 72 volt 82 nominal with 50 amp speed was up around the 65 to 70 kms phr
is it faster? look at that smile dad, 😊😊
These smaller motors have no issue running on 48v 52v etc, but you definitely don't need that many amps or watts, a 22a KT would be better because you will still get the improved top speed but not so much stress on the geared hub.
What’s a 22a kt?
@@La01781 Just a brand of controller, KT you can pick them up cheap, Decent and have a lot of settings to play with as well.
I do the same as you . If I am on the road outside my house testing ,I don’t wear any safety gear 😂 . Then I do the full safety checks and put the helmet etc on and go for a good ride . It’s like I feel invincible when on the road where we live 😂👍
Does anyone else from N America get anxiety seeing people drive on the opposite side of the road and going into those roundabouts? I sure do, I went to the UK and Australia and felt my blood pressure rising.
Awesome Experiment! So, power is more in the battery than the motor... Thanks for the eye-opener. You've got my wheels spinning on many possibilities. Laws here limit our ebikes to 750 watts. But 72V to a 36V 750 watt motor might be great! Also, setting wheel size smaller allows for more speed before the governor kicks in. Hmmmm.....
Well the motor makes more POWER when you feed it higher voltage. 250w@36v is about 7A. Feed 7A @52v in the same motor, you get 364W. All things being equal of course but you get the idea.
@@lunchie80 What do you know about 'blending' a 72V battery to a 48V battery/motor system to up the 'working voltage' of the bike to 60V...?
@@johnw65 thats not gonna work
@@bobosneef2 I see a lot of folks putting 52V to 48V motors... Is there a limit? As long as the controller can handle it?
Great work you do but I think this one’s a neg for me all that power on the front steering in the wet with noblies just don’t do justice for me .
have you touched the motor to check its temp? didnt the motor start to get hot as you used it? it really roars now. what cells is that 52v packing? i've the same casing but my battery is 48v13ah 13s4p and i have another case and id like to make a 52v 20 ah battery pack
Did you changed the controller when you used the 52v?
Not bad for a 250 watt motor my cube does 35 ish on flat shop bought pedal assisted pedalling like mad lol
seriously conider the power on the front forks my rockshocks snapped and i ended up broken arm broken teeth scared down my legs so i re sleaved my forks with steel and strengthened them up with a brace and new drop outs and now its awsome
This happened to me too. Dropouts sheared off. Fortunately I was coming to a stop before it happened so no injuries. Shouldve put a torque arm on or 2.
Phaserunner, and 4 x Makita 6ah 72v
My speedo is off too but unable to change it so I just use GPS. These little "250w" geared motors can take way more than that...most of them can handle way more, anyway, I think the plastic gears inside the hubs are the weak point. You can buy replacements for very little money, and I bet you could replace the plastic gears with metal ones if you know how to measure and count teeth. The 9-pin cable would melt before you damage the motor with amps / heat, imo. You could probably open the motor and replace the 9-pin with 10 guage wires.
This video was a year ago, did the 52v battery conversion last that duration or did it break down in the last 12 months?
Did any part of the controler wires motor or battery over heat
Hi Dude new to ebikes just got eleglide m1 plus how and what do I need to make faster staying safe any kits or what thanks mate
So nothing as burn up is it still riding because if so I’m gonna do the same I have a 250 watt hub and been wanting to do this ?
my bikes battery is now 3 years old and sagging heavily ,its a generic beefy 1kw motor im wondering if its worth the investment buying a 2kw controller and a new battery to match, speed isnt so much the importance but the extra torque for going up hill and acceleration
Thats really good from a 250 motor. Average 50cc motorcycle will only get to roughly 30mph if you're lucky, and you have to tax, insure and mot those. Nice job.
Does this improve the torque on it?
Well done mate, I was thinking of doing this with 250w hub but wasn’t sure if it would work. 👍🏼
If your existing motor isn't rated to use 24 volt battery
Wow that's pretty good. I've recently become disabled through arthritis in both knees. I was thinking of an electric bike to help me get some exercise and be kind to my knees. In your opinion what should I be looking for. I don't want any goofy looking bike either with tiny little wheels. That bike looked good but what is it. If anyone else can help with advice please let me know.
I subbed
Back wheel drive always better Back wheel drive will be digging itself into the road, but front wheel drive will be trying to left itself up off the road and skiding
I want to see this video made in snow or winter conditions :D
The gears in the motor are made of plastic, so I wouldn't overdo it too much. Plastic is here more durable than metal because there is less abrasion, but only if it doesn't get too hot.
You can put any voltage you want through any motor you want to...
What display are you using?
put front tork bar that will stop the front wheel from going slack because of the power that what i did to my ebike front wheel been tight ever since
My wife Emmo is 72 volt and I see now they are 84v, I want to upgrade her controller but don't really know how. The lead acids that come with the bikes are garbage, I upgraded hers to LifePo4 batteries which are safer and go for 1000 charges. Been 4 years and we are going to upgrade her battery to a 72v 40ah from 20ah for more range.
2nd comment, sorry but another question, could ' you' upgrade a Rad Rhino 6 plus ?
ThNks ,,,,,,
Should have supervised the boy doing the work.
Gonna do this with my spare 250 on a used bike as a spare
1 problem with front hubs, if they fail, they become a generator and you're over the handle bars.
If that was mine, that front wheel would go on the back, take off the chain and put another front on it. Much stronger and better to ride IMO.
Hello mate ive just got a 60v 20ah battery has a 50a bms cells are molicell p42a 21700 could i run my csc 1500w kit without it overheating i am aware ive got to change controller anymore ect tips thanks mate
How many watts your controller can handle ?
Beast
Just my opinion, do what you like with it. When you overvolt a motor, it definitely wil deliver more until that fateful day when it gets too hot and burns up on you. However, if you dont hold the throttle open too long or too often, you might get away with this for a very long time. I once overvolted a 24v motor to 40v. It lasted 6000 kms. Unfortunately, I got so acustomed to it working well, I absent mindedly ran it into a wind for an hour and cooked the motor.
Yeah that's the thing It works until you put too much load on it. What people forget is that in order to reach equilibrium when going from 36V -> 48V battery for example, is that you should also swap out the controller for something that can either be current limited, or a weaker controller that delivers lower max Ampere. Otherwise it's a gamble in the long run.
The S886 display has P14 Current limit for example, the controllers that are compatible with that would be ideal. As you can lower the current settings to make up for the 30% boost or 40% boost in Wattage when going from 36->48, or 36->52.
Same principle for you if you went from 24->48.
@@JesusChrist-sx1lf dude change your name, you are probably offending a hundred million people.
that works but overheating the motor will cause the magnets to loose strength overtime
Be nice to know what sort of range you getting. And how many ah the 52v battery is?
If I had to guess, the battery is 20 aH, maybe upper teens at the very least, judging by the size of it.
I have the pure flux, is it possible to improve the speed?
Do you prefer grip throttle or thumb? I’ve tried both and I like thumb more at the moment. It feels safer off road
Yep!
@@delmanorshun2471 What do you mean 'Yep!'?? The guy asked a question, grip throttle or thumb. Answer the question boy.
Dude, looking at your post on UA-cam I don’t think there’s anything you don’t know about these bike kits, so would you know if the control box I currently have running a 500w motor, run a 1000w motor? I already use a 48v battery with the setup, no problem, are these control units all the same? Thanks. Mick
It's preferred that the controller have a equal or higher wattage rating than the motor, otherwise you are going to push the controller to it's very limit once you reach a certain speed or if you're going uphill and don't use pedal assistance which can cause it to overheat. But yes, it does work under some circumstances. If you use it with pedal assistance and maybe not the max mode, then for sure.
I have a 250w 48v ebike if I put a 1000w controller in will that work?
good just dont go mad on throttle bro
14 squid for that cable?! That’s an expensive cable, how long did it take you to catch the squid, two-free days?
what size contor did you put on
Nice, may I suggest you buy your son a cycle helmet for Christmas?
I'm thinking : could I add a 250W front hub motor to a 250W rear hub motor bike and still technically be road legal?
🤣
Really don't think he cares enough tbh mate.
Which makes a mockery of the law as a 250watt motor quad volted appears legal when a 1kw motor restricted to 250 w is illegal . The law is an ass .
Thats what we can a electric bike grin you do it the 1st time on a electric bike or after a upgrade
Front wheels are dangerous I know because I nearly smashed my face on the road at 20mph the steel forks broke off due to the motor torque and went flying off the bike but luckily I ended up doing a roll as I landed which saved me from any injuries never bought a front wheel again rear wheels all the way
smokes a crkack pipe part 3 i have just had 1 just sot me right out
get rid of balance wires ?
Set magnets to 46 and it fix speedo
Please can you recommend a bike hybrid/mountain, more hybrid because mostly flat and built up roads. I’ve been looking so long for the right bike but the options are endless. Online, people have very mixed opinions on what bike i should get. My budget is ~£800. Thanks
I've had a trek fx1 + yose 350w/36v/13ah
For 12 months, perfect match for me £415(bike +£380 (kit)
Look for an older steel Trek Multitrack, Specialized Crossroads, or Giant Innova. I think the steel dropouts could handle the torque of the motor better over the long haul. You could also beef them up with a little welding.
Nice and easy
Would love to do this but would ruin my bike plus shit at electrics 🤣🤣, also definitely need to be waterproof as I would be riding it to work in the rain
Look at a video on Electric Bike Laboratory where they disassemble a hub motor and waterproof it with spray epoxy, then add Statorade to improve cooling.
I run 52 v battery on 250 w after 2000km motor broken 😅 for now I want try 500w on 52v
