Electric Skateboard Motor Buying Guide 2021


What are the Secret of an Electric Skateboard Motor? 

Choosing the right electric skateboard motor is essential when it comes to fun rides and performance.

 

Nobody wants to end up with a good-looking piece of junk that can’t carry its weight. If we care about the aesthetics the manufacturers know how to appeal to that side of us – but we want all the power that the skateboard can give to us too!

 

Which is why we’ve taken time out to look at what is an e-skateboard motor, basic points and what could you get in the market.


Electric Skateboard Motor Configuration

We’ll just go right ahead and say it.

Whether you’re building your own electric skateboard or buying one already made, there are clear differences between what is available and what they can do for you.

What you need to know here is about the power delivered using a dual-motor or a single one.

 

Dual motors

As you can infer, dual electric skateboard motors is a combination of two (2) single ones; same power and characteristics.

They come as belt-drive or hub configuration. More detail will be discussed in the next section.

 

Power and torque are also a key difference between each class.

 

Belt-driven ones will require more battery energy to power their motor size.

Ironically, one thing that some buyers realize later is that they don’t need all the power a dual motor delivers.

For one, weight is an important consideration when choosing the right power in your motors. This is more important when skating uphill.

Users who don’t tip the scales at a high weight level can settle for single motors and think that will be fine.

 

Single motors

It is rare to see electric skateboards with only one motor.

MY PICKS

 

Demeras Single Skateboard Motor

Demeras electric skateboard motor single configuration

 

✅: 350w of power single motor with a 25km/h maximum speed.

X: Only suitable for e-board that are less than 910 mm wide.

 

 

XiAOLL Brushless Wheel Motor

 

XiAOLL Brushless Wheel Motor 250 w

 

✅: 250w that can reach 20km/h maximum speed. Not bad for a single motor.

X: It is only the motor, so you might need to buy the other parts to transform your eboard.

 

 

Vikye 36V Brushless Hub Motor

Vikye 70mm 150W 36V Brushless Hub Motor

✅ It is a good option for a beginner that requires low power (150w) and still reaching 15km/h.

X: 70mm diameter, which is okay but will give low ground clearance.

As far as we are aware, only Liftboard has a single motor configuration. Based on what some users say, the efficiency is not bad.

The main reason is that it will feel and drive slowly when you are on flat ground but you’ll really start to feel the lack of power when you’re going uphill.

One positive thing about them is the lower overall weight compared to the dual ones. Besides, that would be less maintenance in the long run.


Types of eSkateboard Motors

There are two (2) main types of eSkate motors that we will consider here: hub and belt drive.

More motors have come up in the market (like the direct drive – which is also a form of hub drive – and gear drive models) but they are yet to crack into the hearts of users and techies alike like the others.

So, we’ll consider the top two, which is the best for you and why?

 

Double rear hub motor

Hub motors are usually located at the end of the eSkateboard, hence the name rear hub motors. In this setup, the motor is attached directly to the wheel that it drives.

 

SOME RECOMMENDED DUAL HUB MOTOR ALTERNATIVES TO LOOK AT

 

VGEBY Brushless e-Skateboard Motor

VGEBY Brushless e-Skateboard Motor rear hub

 

✅ 90 mm wells (good clearance), 900w power combined.

X: Wheels could be hard to replace.

 

 

Promotor rear hub motor

Promotor 90 mm wheel double hub motor for eboard

✅ 550w of power that each motor can deliver. This translates to 30km/h speed.

X: the truck shaft is a bit short so possible not so suitable for electric longboards.

 

 

Shikha e-Skateboard 1100w Rear Hub Double Motor

 

Shikha dual hub electric skateboard motor with 1100w power combined

✅ Seven (7) inch trucks with 90mm wheels, which is good for e-longboards.

X: It does not include any other parts aside form the motors and trucks.

 

 

Instead of referring the energy to the wheels through a system of gears and belts, the motors directly impact the performance and speed of the wheels.

This allows for less energy loss in the process of transmitting energy from one form to the other.

Good stuff about them:

Perhaps the biggest advantage of rear hubs is the fact that the eSkateboard continues to move like a normal skateboard if the battery power dies.

Another one is that they also have greater braking control and improved efficiency. This could make sense since there is no other parts involved.

Likewise, the hub’s format means that it needs lesser moving parts. That means fewer overall costs in the long run, lesser time to take apart and re-assemble, making a cleaner overall setup.

The downside:

Unfortunately, things are not all rosy here. Some of the downsides are:

  • A rear hub configuration cannot manage heat the same way as belt drive systems. This is mainly because of their enclosure system.
  • They almost always restrict users to the use of wheels that come attached to them, crippling the true DIYers who want to customize it all.
  • Lastly, impact absorption may not be as good as expected since the PU composition of the wheels.

Double belt driven motor

The belt drive motor systems has been around for over 20 years, so we will try to explain it too much in detail, but if you got into eSkateboards early enough, chances are that you’re used to this technology.

 

ZXMOTO Electric Longboard Drive Dual Hub Motor

 

1500W ZXMOTO Electric Longboard belt motors

✅ With a total of 1500w of power, you can reach up to 35km/h.

X: A bit noisy, heavy set. In addition, no belt tensor system available.

 

 

FFMT dual hub motor

FFMT 1500w motors with 83mm diameter wheels

 

✅ It could reach around 40km/hr and torque is quite decent.

X: Wheels are only 83mm, which could be not enough for ground clearance.

 

Still today, belt drive systems are famed for their faster acceleration due to much better torque transmitted by the belts. They are also stronger at climbing hills thanks to the unique gearing system.

 

Furthermore, this belt drive electric skateboard motor manages heat well, providing longevity for the motors and wheels alike.

 

They sound great, right? but there is mayor issue with this configuration.

Once it comes to weatherproofing though, they fall flat. The belt is usually there for all to see, which will also gather dust and moisture faster.

Having said that, best maintenance practice is to cleanup the belts after every ride. Of course, this is in an ideal world, so do it at least if you have been skating off-road or for a few days in a row.

As for the price side, they are more expensive for all the part involved.


Things to Know When Choosing the e-Board Motor

Depending on which of the electric skateboard motor options above you are settling for, now you need to know how to choose the best one.

Unfortunately, the average Joe can’t just walk into a hardware store and get the best pick unaided. You will need an understanding of what makes the motors good at what they do and why.

We’ve looked at those notable points below:

 

Electric skateboard motor size: Diameter and Width

There are two (2) sizes in the motor to look at: the actual size of the motor the stator one.

Most people only check the first and assume that a bigger motor is a more powerful unit; that’s not quite right.

Look into how big the stator is too and use that to make a better-informed decision.

That said, every motor will come with a 4-digit size imprint. The first two digits denote the diameter (in mm) while the other two refer to the length (in mm).

 

Flipsky Size electric skateboard motor reference

 

For example, from the image above, the size of this Flipsky motor is 63 mm diameter and 74 mm width.

 

What is an stator? It is the plates of the motor that spreads the electricity current to the wiring to the rotating parts.

 

KV Rating

The KV measures the number of revolutions a motor can give (usually under a minute) when 1 volt of power is applied.

 

This measurement is taken when the motor is free of a load. The interpretation here is that a higher KV rating means a higher motor power, which in turn will guarantee you a higher speed.

 

A motor with a higher KV will have a lower torque plus higher top speed, and vice versa.

 

Electric skateboard motor watts

The wattage (or power supplied) by a motor is a function of two (2) parameters:

– Current – measured in Amperes (Amps of A); and

– Voltage – measured in Volts (V).

Manufacturers will sometimes just include the power rating up-front, but you can use the ampere and voltage to make better choices.

For the voltage, most motors support a very wide range (from about 4 – 15V) so you shouldn’t have an issue with that. Your skateboard and motors will intelligently pick which is best for them then.

 

The same cannot be said for current, though.

 

So, always make sure your electric skateboard can draw at least 5% more current than the motor provides.

For example, if your motors provide 75A each (which makes 150A for two motors on the board), make sure the board itself can draw 157.5A as a minimum. Otherwise, the board could get fried during operation.

 

Wheels Compatibility

Like we said above, it’s difficult to modify the wheels on a hub motor.

If you don’t mind going with the provided wheels, you are welcome to try them out. If you would prefer custom wheels, you might want to see what the belt drive systems have to offer.

PS – The hub market is growing quite fast and manufacturers are trying to churn out more sleeves for hub motors. There’s a lot of potential in the wings, if you can wait for it!

 

Battery Compatibility

So, which batteries should you invest in?

The first thing you’ll notice is that some batteries come in series (S) and some in parallel (P) arrangements. Even if two batteries had the same rating, the arrangement will make a difference.

While there are a lot of factors to consider, this general guide should help.

PS – You can mix both types of batteries. Here’s what you get from each class:


Electric Skateboard Motor Wrap Up?

As you have seen, this part of an e-board affects your ride.

Which ever configuration you pick (dual – single, belt or hub), you must do proper maintenance so the performance doesn’t drop.

Keep in mind that the topography of your area influences what motor you should go. A weak motor (eg, single configuration) is going to disappoint.

Now that you know all that goes into an average electric skateboard motor, how will you make your choice?

No matter which one you go for, we are more confident that you would have made the right choice.
