Exway Atlas 4WD All‑Terrain Range Test

Recently I measured the range on my pre-production Exway Atlas in 4WD configuration with the stock all-terrain kit. I’ve already done range tests in the other stock configurations:

Remember, lots of things affect range so please read through the ride conditions. This post isn’t a full review. This is only covering my recent range test.

Conditions

I rode from 98% battery down to 13%. My unit has an issue with the BMS or something so it wouldn’t let me charge to 100%. At around 10% or so, I got a 4% low voltage warning. After clearing the warning, the battery indicator was back to 12%, and then 13%. The indicator percentage seems to fluctuate when the battery is near empty. (Exway tells me this is normal at low voltage.)

The mudguards protected my pants and shoes from the nasty water.

For this ride I was using speed mode 3 (out of 4) almost the entire time. Unlike my previous tests, I didn’t use full throttle very much this time. I went exploring and the places I ended up didn’t have many clear straightaways. The terrain I rode on this time wasn’t very smooth, but wasn’t too bumpy either. There were lots of dust and cracks. They are paths that I would generally avoid if using longboard wheels.

My weight was 79 kg since I was carrying a bit more stuff. The weather was 18 ºC (64 ºF) when I started and about 16 ºC (61 ºF) when I stopped.

Results

I measured the range using the Ride app and my GPS watch.

On the Ride app I got 24.6 km (15.3 miles), and on the watch 22.7 km (14.1 miles). Like I mentioned earlier, I stopped at 13%. I probably could have eked out another kilometer but I had to take a dump and I happened to be next to a mall.

This rear mudguard is positioned to protect the rider but not so much the ShredLight and anyone behind the board. It can be flipped around.

Exway’s website claims 27 km (16.8 miles) for 4WD all-terrain which isn’t too far off from what I got. If I had stayed at a more constant speed and picked a smoother route, I probably could have gotten their claimed range.

Also, the finalized Exway app is supposed to let you adjust the power for the front and rear motors separately. That may affect the range as well. For normal everyday use, I would set the power for the front motors very low, or even set the board to 2WD.

Exway Atlas 4WD 90mm Range Test

A wheel flew off during this range test LOL! I felt the back veer to one side, skidded a bit, couldn’t control the board and ran off. I didn’t even know a wheel had come off until I looked back at the board. Found all the pieces except for the nut and speedring.

It was my own fault. I looked through photos and saw that I didn’t tighten the wheel nut. See what happens when I don’t follow my own advice? Check all fasteners regularly!

If you zoom in on the wheel at the far left, you can see that I didn’t tighten the nut.

Anyway, on with the range test stuff. Remember, lots of things affect range so please read through the ride conditions. This post isn’t a full review – it’s only covering my range test on the Exway Atlas 4WD with street wheels.

Conditions

Since this range test was interrupted by the wheel flying off, I had to do it in two parts. In the first part, I rode from 98% battery down to 28%, which was when the wheel came off. And then later that night I rode from 28% down to around 13% when the acceleration had dropped significantly.

The remote was showing 13% when I decided to stop the range test. After I let go of the throttle, the remote went to a warning screen showing 3% battery left. The power measurement seems to fluctuate more when the battery is low.

I tried to stay at around 30 km/h (19 mph) but often had to slow down for traffic and whatnot. I was also stopping here and there to take photos.

Exway Atlas remote showing 3 percent battery.

I was in speed mode 3 most of the time and only switched to mode 4 a couple times to test the acceleration and top speed at about 80% battery and again at about 50% battery. Got 47 km/h (29 mph) at 80% and 43 km/h (27 mph) at 50%.

Although the top speed dropped at 50% battery, I did not notice a difference in torque. I didn’t measure scientifically but staying on the board at full throttle from a standstill was still a challenge.

In mode 3, the top speed was about 35 km/h (22 mph), and at below 50% it dropped to about 30 km/h (19 mph). At 25% it was something like 25 km/h (16 mph) and the torque reduction was noticeable. Again these were top speeds at mode 3. The top speed was always higher in mode 4 but I didn’t want to measure that too much during a range test.

In the first part of the range test, my weight was 78 kg (172 lb). The weather was 20 ºC (68 ºF) when I started, and then dropped to 18 ºC (64 ºF) by the time the wheel came off. During the second part, my weight with an added jacket was 79 kg (174 lb) and the weather was 14 ºC (57 ºF).

Results

For this ride, I measured the distance using the Ride app and my GPS watch for both parts. In the first part, I got 27.7 km on the Ride app and 26.17 km on the watch. In the second part, I got 6.2 km on Ride, and 5.74 on the watch.

So in total, the range results were 33.9 km (Ride) and 31.91 (watch). Let’s call that 33 km or 20.5 miles. That’s roughly 18% less range than the 40 km or 25 miles I got in 2WD with street wheels.

Next I’ll measure 4WD with the stock all-terrain wheels.

Exway Atlas 2WD 90mm Range Test

I actually completed a range test on Exway Atlas 2WD with street wheels (90mm, 36T pulleys) two weeks ago. Just didn’t get around to writing about it so here goes.

Remember, lots of things affect range so please read through the ride conditions. This post isn’t a full review. This is only covering the range test.

A rock briefly got stuck between the motor and motor guard, leaving a streak on the motor and pushing it inward a bit. I noticed the belt grinding while braking and stopped to readjust belt tension.

Conditions

I rode from 98% battery down to 8% when the board stopped accelerating. After a few minutes the indicator was back up to something like 12% if I remember correctly. I thought the smart battery wasn’t supposed to deviate that much. Oh well. I rode from 98% battery because my unit has an issue with the BMS or something so it wouldn’t let me charge to 100%.

For this test I was riding in speed mode 3 (out of 4) almost the entire time. I would expect less range in mode 4 and more range in mode 2. The acceleration and brake strengths were set to max in the app.

According to the Ride app, I hit a top speed of 47.8 km/h, or 29.7 mph, in mode 4. That might have been a fluke, or maybe I was on a downhill slope, because Exway claims 43 km/h as the top speed in 2WD street. I don’t remember the top speed of mode 3 but I think it was in the mid 30s km/h.

In my range tests I normally try to stay around 25 to 35 km/h. Not completely sure if that was what I did for this test since it was two weeks ago but probably.

My weight was 78 kg and the weather was 24º C (75º F).

Results

For this ride I measured the distance using the Ride app and my GPS watch. I couldn’t use Exway’s app because the beta app for setting gear ratio and wheel size for Atlas is only available on Android and I’m on iPhone.

On the Ride app I got 42.8 km (26.6 miles), and on my watch I got 39.5 km (24.5 km). Exway’s website claims 54 km for 2WD with street wheels. Well I didn’t get very close to Exway’s number. For a 518 Wh battery I thought I would get more than around 40 km, but for me personally I’m fine with that result. I was tired by the end of the test anyway and was looking forward to recharge the board and myself.

By the way, just something I thought was kind of neat: the torque on 90mm wheels with 36T pulleys felt the same as the pneumatic 160mm with 56T. I didn’t measure scientifically or anything but just from feeling, they felt the same.

Anyway, next I’ll measure 4WD.

How to start e-skating at 40 years old

Q:

As a 41-year-old guy with zero boarding experience I’m hoping you can give me some advice for myself as well as the board itself.

A:

Here are some steps I suggest for a complete beginner:

  1. Get a helmet that fits well. If you buy online, check the return policy in case it doesn’t fit well.
  2. Watch some YouTube videos on how to ride a longboard so you learn foot placement and weight distribution, etc. (I should probably make a video on this.)
  3. Practice riding slowly – slower than you can run. Take as long as you need. You might find that you need to work out your legs more.
  4. Before you start riding faster than you can run, I suggest getting gloves, elbow pads, knee pads, and maybe even hip pads, and practice falling with them. Start by just standing on the ground and touching the ground with your hands, and then rolling on the ground. Getting familiar with how it feels to be on the ground helps a lot. I’m 39, I normally wear all the pads (except hip pads) if I’ll be riding faster than I run.
  5. Understand that falling is a normal part of skating. You’ll fall at some point so practice and ride accordingly!

For maintenance and other tips, I suggest watching the videos in this playlist:

Police confiscated my Exway Atlas

Shanghai – and possibly all of China – doesn’t allow personal electric vehicles to be used on public roads, and not even sidewalks. The enforcement of that rule varies a lot. Sometimes the traffic cops ignore me, sometimes I get a warning, sometimes I get fined. Yesterday was the first time they took away the board. It was the Exway Atlas during my 2WD street wheels range test.

The officers told me I need to go to a police station on Monday to get the board back. Sounds simple enough. That means I have to postpone the big comparison shoot I had planned for Monday. The problem is that while the board is confiscated, it will likely be kept outdoor along with the confiscated cars and scooters – and the next couple days will be raining.

Police confiscating Exway Atlas

That is a huge problem. Electric skateboards and other PEVs (and most electronics in general) should not be left out in the rain, even if they claim to have some kind of IP rating. Water finds its way into places if you give it enough opportunity.

Best case: some replaceable parts get rusty. Worse case: something gets corroded and the board loses performance or fails. Even worse: the board catches on fire while charging or riding. And the very worst case: everything seems fine but weeks later the board starts shooting flames at home while unattended.

When I go get the board back, I’ll find out if it was left outside in the rain. If so, I’ll have to take everything apart as much as I can and carefully inspect them. Sigh.


Update: I got it back! See video below.

Exway Atlas 2WD All‑Terrain Range Test

Yesterday I measured the range on my pre-production Exway Atlas in 2WD configuration with the stock 160mm all-terrain wheels and 56T pulleys. Remember, lots of things affect range so please read through the ride conditions. This post isn’t a full review. This is only covering my recent range test.

Conditions

I rode from 98% battery down to 8%. My unit has an issue with the BMS or something so it wouldn’t let me charge to 100%. At 8% the board stopped letting me accelerate but I could still brake – this is normal on Exway boards.

For this test I was riding in speed mode 3 the entire time. (Mode 4 is the highest.) I would expect lower range in mode 4 and higher range in mode 2. The acceleration and brake strengths were set to max in the app.

Exway Atlas next to Long Museum

About half of my ride was in full throttle, which was limited to 34 km/h (21 mph) in mode 3. (Mode 4 gets me to 43 km/h or 27 mph.) The other half was in slower traffic with more stops and starts. I carved a bit but was mostly riding straight. The terrain was mostly flat asphalt roads with some gentle slopes on bridges.

My weight was about 74 kg and the weather was an unusually warm 24º C (75º F). Shanghai sometimes gets warm and humid right before a bout of rain.

Results

On Exway’s app, which measures speed and distance based on the numbers you enter for the wheel size and gearing, I got 32.2 km (20.0 miles). On the Ride app, I got 30.9 km (19.2 miles). Exway’s website claims 30 km for 2WD all-terrain but doesn’t state the ride conditions. I was a bit surprised but pleased to see that my numbers are close to their claim.

Again note that this range test was on the 160mm all-terrain wheels and 56T pulleys, which are what most buyers will use since those are the stock parts.

Atlas 2WD’s 2-in-1 combo includes 90mm urethane wheels with 36T pulleys, which Exway’s website claims would get up to 54 km (33.6 miles). Exway also sells separately wheels in 85mm and 80mm, and pulleys in 26T and 44T, so you can further fine tune the board’s performance.

Quick thoughts on Exway Atlas 2WD

I recently got the pre-production Exway Atlas back from Exway after they installed the bigger final motors and changed a couple other things. I wrote down some thoughts which I was going to post on Instagram, but if I write anything about Atlas there I’ll be asked a bunch of questions that I don’t know the answers to yet. So I’m posting here instead.


Atlas! I had a blast with 2WD and Turbo! This is the first board with double kingpin trucks and all-terrain wheels that I’m comfortable riding at over 40 km/h. Didn’t tighten the trucks or anything. At one point I hit a bump that would have caused a more violent wobble on another DKP AT board but instead Atlas just swayed a bit and straightened out.

This was 2WD with 160mm wheels and 56T pulleys, and the bigger final motors. Unweighted top speed shows 46 km/h on the remote and I topped out at 43 km/h. I was 77 kg during the ride.

Used up 60% of the battery and rode 21 km, so a depleted battery would have been about 35 km (100 * 21 / 60). I know that’s not the best way to estimate range – I’ll range test another time. 

First half of the ride was in mode 3, doing some carving. Second half was in mode 4 with Turbo and being a slight dick to cyclists and other motorists. Sorry but I had half a cup of coffee this morning and I’m not a coffee drinker. I wanted to see how fast I could go and how fast I could corner, so lots of hard brakes and hard acceleration (during second half of ride).

I generally don’t like DKP trucks for more aggressive rides but Atlas’s trucks are a surprising exception. And these pre-production trucks aren’t even CNC machined yet – the bushing seats look all lumpy – but I feel they perform well anyway.

For those who want DKP trucks for low speed carving, I think some people may feel like they need to change the bushings to softer ones or cones. No biggy, that’s really easy to do. For me the stock setup is just right.

Questions

Should you get Exway Flex or Exway Wave?

Q:
I’m planning on purchasing an Exway board later this month. I’m just split between the Flex or the Wave. I work 4 miles away from my house so it’d be an 8 mile commute total. My town is pretty good for skating. I’m just not sure which one would fit my needs better. 

A:
8 miles roundtrip should be doable on both boards if you’re under 200 lb and have no hills. (This may be useful.) Otherwise I suggest just charging the board at work. As for Flex or Wave, I personally find the Wave to be more convenient and I use it more than other boards. But I like carving more on the Flex, though the stock bushings are a bit hard for me.

Board in storage with fully charged battery – How bad is that?

Q:
I recently purchased a meepo v3. I was only able to ride it twice until I had to pack into a non-climate controlled storage in December. I made the mistake of packing it away with fully charged batteries. Unfortunately, I won’t have access to it until March or April due to Army stuff. Do you think it will be fine when I’m finally able to unpack it and ride it again?

A:
For a Li-ion battery, you can assume roughly 20% loss of battery capacity per year if stored at full charge in room temperature. In low temperature the degradation should happen more slowly. If your electric skateboard will be left unused for more than a week, try to store it at around 50% charge, preferably in cool temperature. Best to double check with your board’s manufacturer.
