- Why 80mm wheels?

After testing different prototypes with different size wheels, I found small wheels have tendency to catch and do not slide as smoothly as bigger wheels.
The placement of the wheels out front serves many purposes:
It allows for any size wheels, big or small, and as much clearance from the ground as needed. Wheels placed in front of the foot pad instead of under mitigate nose dive better. I find that when I'm out riding and look down at the wheels, I get a distinct sense of the safety they provide, and I do think these are the most appropriate wheels.
There's enough clearance for carving and going uphill. In stationary tight turn situations, wheels may touch the ground and that's no different for bumper wheels. Usually steep tight turns are done by pros for stunts/tricks and most riders don't usually need full clearance.
As for the look, although they stand out, many buyers love the convenience of the front grab handle and don't mind the look at all.

- Is Onewheel with front wheels considered a 3 wheeler?
Yes, when you nose dive. At other times, it's still a Onewheel. :)

- What about the front clearance with Slider and do the wheels interfere at all?
Slider wheels are mounted out front and that gives Slider a distinct advantage. It's even possible to use 100mm wheels and have as little as 1/2" angle reduction. That's less reduction than any bumper wheels in the market.
However, upon a nose-dive, it's the steepness of the angle that throws the rider as well as the momentum. After testing different angles, a slight reduction in angle along with good size wheels offer the best chance for nose dive recovery. There's plenty of clearance for normal riding, carving and going uphill.

- How much does Slider weigh?
Under 2 lbs.  Each Slider is custom built from steel, wire brushed and painted then mounted on and fitted to ensure alignment and ease of installation.  Arrives complete, no assembly needed.  Takes less than 5 minutes to install.  Since most boards get a rear foot pad upgrade which is about the same weight as Slider, board balances fine.  Many boards now are also getting an upgraded battery which weighs more than the stock battery and Slider will counter balance that as well so it doesn't feel tail heavy.

- Is Slider effective off-road?
Slider is meant for pavement although you're probably not better off on stock bumper off-road. Truth is, no front safety wheels device is 'effective' off-road due to too much drag.  Personally, I keep it on at all times.  However, it takes few minutes to remove for situations where it may not be needed.

- Can I use Dewalt battery?

No. Kits are made for specific battery types. For XR and Pint. Greenworks, Powerworks or Jialitt. You will need 60V. For the Plus and V1. Ego 56V. The more AH, the better range you get.

- How can I tell how much battery I have left if I can't open app?
You can still open the app and check voltage under settings. Just disconnect VnR, power cycle board, open app. Then disconnect app and reconnect VnR. On the Pint, the front LED will give a good indication of your overall battery percentage. Best method is to know your total estimated mileage from the start and simply track your mileage through a separate app. Once you get the hang of it, you'll rarely ever need to open app.

-Can I connect fully charged battery when Onewheel is empty?
That's called hot swapping and is not recommended. When you connect a fully charged battery, a rush of current will go into the depleted battery and it will affect its health/lifespan. 

-Why is VnR the most preferred method?
All high range electric personal transportations run several packs in parallel. VnR is no different. It takes about 10-15 minutes to install and increases the range to as many external batteries as you can carry. EGO 7.5 will add 18-22 miles on the Onewheel Plus. Greenworks 5.0 will almost double the Onewheel XR range.

-Is it okay to charge EGO/Greenworks with the Onewheel charger?
Yes. Tool batteries have a built in BMS and will charge/discharge through the BMS. It will take longer to charge of course. Some will use the EGO/Greenworks charger for a faster charge.
