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.
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.)
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.
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.
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.
