Thank you very very much, very kind and very well explained. I have a gearless 1000 W 48 V front hub in my bike. I'm thinking in a 2wd bike with a geared hub in the rear, any recommendations?
No worries! thanks for watching. That would be interesting to do. I don't see why it wouldn't work. eventually one motor will outrun the other. But it would give a good torque out of the geared hub to help accelerate. would be interesting to see.
@@diye-bikeswithjonny5398 I got a 750 bafang rear hub geared and an ebay 1000 watt front hub motor.I pedal on PAS 3 with the 750 and for trails and steep hills use the 1000--it is a perfect combo.I also use the 750 on sidewalks or to navigate tight areas--and use the 1000 also if I have to travel a long distance fast. I plan on using the front hub for the heavy work to extend the lifespan of the rear gear hub because they are so much harder to replace. I hav 96v and 34 ah--2 batteries and am easily getting 80 miles plus range.I did 60 within 3 days and the 1000 watt motor connected to a 48v 20 ah battery had half charge and the 750 still had a full charge.Hill climbing and heavy trail riding is a breeze and the front hub actually keeps the wheel hop down on trails. I have vids on mine.The 1000 can also do hills at 22 to 28 MPH by itself on hills that the 750 was doing 12 mph--if I use them both on hills the bike will keep 25 to 28 on steep hills and can do the steepest hills in a few seconds if I need to.Front hub is so strong that I usually do not engage it unless I am at 10 mph because it will spin the front.
Thank you for the explanation. I currently ride a bicycle with a 1000W gearless e-motor. I am thinking to get a second bike with a geared motor as my primary bike, hopefully to increase my range a little bit compared to my current gearless motor.
Yes sensorless motors (controllers actually) have a hard time getting a loaded motor spinning from a stand still. They have to guess where the poles are to apply the right magnetic field. Sensored can apply torque to a stalled rotor to get it moving
Jonny, I'm a mechanical engineer with some insight but not a comprehensive isight into these motors, I have a question for you that will help me resolve a design detail for a concept I'm working on... Can these flat stators iperate perfectly well *if* there was a gap in the stator? In other words, if an eighth of the stator was missing (but the circuit was continued by an intermediate cable or other conductor), would it compel a rotor to spin as normal?
Great videos. Excellent info. I think you would have more viewers if your audio was at a higher level on this and the Kelly controller install programming video (I watched these 2 and subscribed...)
I have an e bike with a geared hub motor. It has plenty of power on level ground and on small grades. But when I climb steeper grades the motor has very limited power. Why does this happen? if you would know?

I reach about 30mph Max top speed on my 1200w rear hub motor from Ebikeling (26’ Fat Tire) I use a 52v 13ah battery which I am upgrading to 80v- Could I simply cut the sensor wires? What will that do? My goal is trying to get past 30mph when I do long straight always on paved bike path
I honestly don't have the knowledge to say for sure how to increase speed . But I do believe at a minimum to increase your speed you have to increase the amps delivered . You might already know , but perhaps checking your controller for a speed limiter as well (and disabling it if so) . But perhaps getting a bms that can deliver a higher amp rating could ( and having a controller than can handle the extra amps ) give you the extra speed. I've put several systems in a couple scooters ( all 72v ) and they varied in top speed even though they ran with identical 20s6p battery packs. I only noticed that the ones that had the bms that could push higher amps would go faster and when switched bms with lower amp rating to same controller would have lower top speed .but like a said I'm no electrical engineer , I could be making the mistake of "correlation does not always equal causation "
Good video mate, the detail I wanted.. how much drag is there in a gear motor without a sprag clutch? Was thinking of using one as the hub of an electric hose reel for weed spraying
It is simple. Geared motor is the preferred motor as you need to climb hills. Here we have no hills and I prefer the normal hub motor. It makes no notice and no maintenance. The gears become a problem after a while. They make noice and the gears will wear out after a while. It depends on how you ride your bike, but it can happen faster than you think. That is why I prefer gearless. Yes it has disadvantages, but as you are up to speed, the Amos it pulls isn't that big and it rides smooth.
The physics of moving a load up a Hill doesn't change because you changed motor type. Geared motors are less efficient because of drivetrain frictional losses.
Very well explained. Just what I was looking for. Thank you.
Thank you for the easy-to-understand descriptions. Now, about that whiteboard...
Awesome info. Just built an ebike with a 1000watt hub, but realized it doesn’t have enough power for hills.

What about thru axle hub motor ?
Is there any practical advantage to having the sensors?
Smoother acceleration and more efficient at slow speeds
Yes sensorless motors (controllers actually) have a hard time getting a loaded motor spinning from a stand still. They have to guess where the poles are to apply the right magnetic field. Sensored can apply torque to a stalled rotor to get it moving
I love the name "Johnny 5". It was an awesome movie.
Does a gear-less hub spin at one speed? Does it increase its speed to match the speed sensor?
Jonny 5 is alive !
How about 15 pole pairs with a fardriver nd84530 with no 15 pole pair setting?

was a good video, but never touched upon:
direct drive brake regeneration and reliability (Which is by far one of their biggest benefits)
THANKS GOD BLESS
Nice
so they are all using permanent magnets as the stator is inside...
I have several interchangeable geared, direct drive front hubs. Bad experience with the Golden Canadians.
Hi what gear oil would you use on a rich bit 350watt geared rear hub motor.ine rquires me to add gear oil after 3months of using it. Many thanks
thank u sir
uh, that's sensor, not censor, totally different meaning- just sayin'...
thanks, my spelling is not the strongest.
@@diye-bikeswithjonny5398 Yeah, spell check doesn't account for context...
Spellcheck. Their getting better as there getting older. Not that you asked but they're you go.
They have dc and just brushless hub wheels
Sensor vs sensor less
I have the Magic pie
The physics of moving a load up a Hill doesn't change because you changed motor type. Geared motors are less efficient because of drivetrain frictional losses.
The amount of amps and torque on the motor to get you up the hill is dramatically different though
... God... always... ...
plastic gears??? really?
well I seem to have a direct drive
Nylon or delrin gears are common and absolutely fine for loads of applications. You will also appreciate the quietness of polymer gears over metal.
