1- it's for 4 passengers
2- weights is about 1400lbs empty(with batteries) and 2200-2400lbs loaded
3- these tires i'm thinking about getting - 23x10-14 https://www.buggiesunlimited.com/golf-cart/set-of-(4)-gtw-14-inch-vampire-wheels-on-a-t-tires/A19-167
4-not sure on the voltage - whatever works
5- I would like to get up the speed 30mph but 20 if just as fine too
6 - I would like to use 2 motors but also 4 motors would be a good option too
7 - i'm not sure of the tires as of yet as I need to replace them - whatever motor I get the wheels will follow
 
Hi
I need help choosing the right Hub motor for my project.

It's a small moped i'm electrifying..

Max load 150kg
Max speed, flat road 80kpm normal cruise speed 40kpm I think.
17" spoke wheel with moped rim
72V battery
this will be for road only, no offroad.
I have my mind set on the 205 50H V3 but am not sure which winding to choose..

If you offer Rims and brake systems, 1/2 twist throttle as well, i'm interested.

That doesnt' appear to work (at least some of the time), as there are posters in this thread (one right on this page) that did not get answered, even after providing the info needed.

I would guess they have so much business they can afford to ignore potential customers.

Hi I am trying to build a three wheeled electric motor cycle and I am interested in one of your hub motor kits for the two front wheels maybe even three(one more for the back for all wheel drive). I am interested in drag racing it possibly doing 10 second quarter miles. I would like one of the kits with the motor already in an aluminum or steel wheel. The vehicle more than likely will weigh less than. 300 lbs 500 with me in it. Do you have a kit recommendation?

Thank you for your message, for your vehicle, could you tell below question:
1. Tire size of your vehicle? For example 130/70-13
2. Max speed requirement?
3. Voltage?

Hello

I have just ordered a QS205 V3 50H from the Aliexpress store QS MOTOR LIMITED - https://qsmotor.aliexpress.com/store/109978?spm=a2g0o.detail.100005.1.d54eedb68huyrs

Can you please confirm that they are a genuine supplier and I will not receive a fake QS Motor?

Thanks
 
Well I don't know exactly what size tire but I would like a 21 inch motorcycle wheel and 144 volts or whatever the maximum is if that's what's necessary there's really no limit because I won't spare much expense when it comes to batteries. Possibly 120 mph top speed.
 
To anyone, but also QS rep
re: 273 v3 motor

Question #1 What kV windings do you recommend?

heavy tandem/cargo eBike application, 26inch wheel, 3inch tire or fatbike if possible for gravel / dirt roads

150kg minimum gross weight, in steep hills, climbing big mountains at 20-25kmh

but up to 250kg fully loaded in flat areas

Top speed is **not** important, but km/kW energy efficiency should be optimized for 35kmh on flat smooth roads

-------
Question #2

I don't know much about freewheels, does this 273 motor use the US standard thread 1.375″ - 24UN?

My friend says to ask if your motor can be made to work with cassette / freehubs instead? I want to use Shimano "Hyperglide-C" type with 11-tooth sprocket.

If not, then is a 36mm wide 7sp freewheel OK?

or is 16mm wide single speed freewheel required, like 16T?

------

What is the overall axle length?

The 152mm is "overlocknut distance" correct? https://sheldonbrown.com/gloss_n-o.html#old

must match my frame "dropout spacing" width, correct?
