I would be careful with range numbers… If you are riding in an environment with any amount of hills or are a taller/heavier person, or both (like I do), you won’t get close to the numbers they advertise. Range is one of the easiest numbers to bs, because you have no idea usually how they even come up with it.
I don’t think these boards will be total crap, but when you look at prices in this industry, you generally get what you pay for… If a board is at a low price, expect a low quality board compared to what what else is out there. I expect they will have a lot of motor overheating issues.
I personally don’t see how they can do this. They must be using a very cheap esc and motor. A decent quality hub motor should cost no less than $150 IMO, the even better ones are $200+ per motor. Then you have a battery, which should be no less than $200 if you want a short range. $300+ if you want a decent range (like what you want). So we are at $600-$700, and we still need speed controllers. High quality speed controllers go for $180 a piece, so your up to $780-$880 for the single, $1060-$1160 for a dual. Then add another $100 for the deck with enclosure. And another $100 for the connectors, wiring, bms, and other little parts. so your up to $980-$1080 for a single and $1260-$1360 for a dual drive with high quality parts, and this is assuming you get the motors and battery at manufacturer bulk pricing cost. bulk pricing of the esc of a lesser quality could save to $100 per esc, so you could potentially pull it down a bit more. But as a company selling completes, they would need to spend at least $800 for a single drive and $1000 for a dual drive. And to the consumer, they would need to mark it up at least 10 percent.
So you can see, it costs a lot to create a high quality board. To bring costs down, and offer the insanely low prices they do, they must shave quality. I would say these boards will be a great gift for kids or young adults to play with as toys. But they are just that in my mind, a toy. They are not a high speed, long range transportation devices, which is more what I would imagine you would want, based on your reason for buying one in the first place…
This high speed, long range portion of the market is small right now, and your options for such are limited. Evolve and Enertion are the two best that come to mind. Ollin board company will have one soon that will destroy everything, and I’m working on a complete that can compete in this portion of the market also.
Just ask yourself what your goals are with an eboard, and understand that the numbers they give in terms of top speed, range, ect. are usually based on light people and while going on flat or downhill only. On my board, 1 block up hill = 5 blocks of flat = 8 blocks downhill. Board manufacturers will never give you these kinds of numbers, because they don’t want you to think hard about it. On my normal route, with over $300 of battery cells alone, I only get 5 miles with solid performance before I sag down to 0%. Get rid of the hills, and 10 miles easily. Half my weight, and 20 miles easily. Board manufacturers will always give you the best looking number they can come up with, so just be careful
