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

[@A_A_K_O_N]

Hello i have a 24v 250w rated motor do you think it will handle 48v ?

[@KM-wl1tp]

Excellent. Your son obviously loved it

[@chrisliddiard725]

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.

[@RayHenry100]

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.

[@johnw65]

Why not 48v on the back 24v motor as well?

[@royweasley247]

😂perfect, I was searching some feed back 350W. Thought it won't change much. 👍 Thanks, go for 500w now.

[@smithmiesterman]

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 ;)

[@mashvids1018]

Well said I was thinking the same thing

[@dastardlyman]

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 .

[@dastardlyman]

dont know anything about geared motors. but direct drive motors are the dogs bollox for overdriving them

[@mattc825]

Thank you mate. Can you give us more details on how?

[@alcurtis93]

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

[@HeinerEder]

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.

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

[@adventureswithsteve2981]

You should upgrade the phase wires inside the motor for thicker wire

[@NS_DAD]

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.

[@JesusChrist-sx1lf]

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.

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.

[@gixxerman1128]

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.

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.....

[@lunchie80]

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.

[@AaronHendu]

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.

[@Midnight17925]

that works but overheating the motor will cause the magnets to loose strength overtime

[@eddiebaby22]

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.

You’re probably not going to see much of a difference with that small voltage increase. Go up to 60v and you will get a lot more acceleration and maybe a bit more top speed. I’ve over-volted small 350 watt scooter hubs with 60v and haven’t seen any over heating yet. Been riding for almost a year.

We purchased this Vivi 27.5” electric bike and a Tentaquil 26” electric bike for our 13 and 14 year olds. kzbin.infoUgkxUiL0GnyDjP32RJdd660sP8mZk4CRLTCJ The Vivi was much easier to put together. With the Vivi, there was a video link to assist with assembly which made the process easier to follow (we did put the handlebars on upside down, but it was a quick and easy fix). With the Tentaquil, the assembly was not as simple to follow, but after we messaged the company for an assembly video, it was easier and they did respond quickly. The other major differences were that the Vivi has a grip throttle on the right handle (like a motorcycle) and the Tentaquil has a push throttle that you use your thumb to activate. The monitors were also different, so if you’re looking for something specific in terms of changing the bikes functions, pay attention to what the monitor offers. We were really impressed with the overall quality and functionality of both bikes, but if you’re looking for more power and an easier assembly, definitely go with the Vivi!
