Xp 2.0, rear tire/motor on front?

[Xp2.0_rider]

Hello, xp told me they sell spare rear tires with motors.

Is it possible to mount the rear on front? Maybe a little over hang from the screws for chain system?

Would this work for a 2nd motor up front? I have a spare battery I can order from ebay, and make a connection to power the motor. (Tutorials on youtube)

Not practical. Two different widths since the rear dropout is wider to handle the gears (freewheel). What are you trying to accomplish? Knowing that I should be able to steer you in the right direction.

I believe the controller would need the extra plug too.

I am trying to have dual motor set up, yet all the motors I searched in past are for 20x4. Xp 2.0 uses 20x3.0

Yes, you said you wanted a dual motor on your original post. I'm trying to understand better why? Just on a simple note you would need to change the controller as the Lectric controller is set up for 500w sustained with 850w peak. Adding a second motor would require at least double that depending on why you want dual motor. In addition, the battery has a practical capacity for only the motor it came with so if you actually wanted to use both motors at the same time, you would likely want to have quite a bit more capacity beyond even the extra range battery Lectric now offers. If I had to guess there are a few reasons that you might think dual motors would be the answer for: Better traction on some sort of surface you want to ride on, increasing speed, or maybe a backup in case the primary motor fails.
My advise to you for each of the three reasons I can think of but not sure if any of them is your reason(s)
To get better traction: The Lectric frame, suspension, and wheel diameter would be dangerous to use in any serious off road use and should be limited to light trail use. The only good reason to need increased traction that the Lectric is capable of is for use on is ice. Money spent on studded ice tires would give you plenty of traction and would be the first thing to try since having AWD doesn't prevent you from needing studded tires on ice anyway.
Increasing speed: You only need to upgrade the controller to squeeze a huge speed increase out of the current motor. Check out Grin Technologies web site for tons of content and parts for the conversion.
As a backup to the primary motor: I would install the Tongsheng TSDZ2 ($300on Aliexpress) or Bafang BBS02/01 mid drive motor. They come with the correct controller and display, you would only need a switch on the battery output to change from one system to the other. Both kits also allow the end user to access factory settings via a usb cable to increase speed limits, max wattage and a bunch of other parameters. I would actually use the new motor kit as my primary and the stock that came with the bike as backup. I have not checked the Lectric bottom bracket width to advise you on which of these kits you would need so reach out if you want further info.
So if I haven't turned you off of your idea and you want to pursue this further, please be a little more detailed on what you think dual motors will let you do that you can't now. Then I would be able to give you much better information.

The main reason is incase the main motor fails, this 80lb bike isn't fun to pedal. Lol!
It wouldn't be primary used for the second motor. I think I could use a second throttle setup, and use a ebay blue battery to run it, wouldn't need to hook it up to the XP electronics . I saw tutorials on youtube with two throttles.
I have esk8 boards, and they have 2 motors on them, I feel the same for my xp 2.0.

I'm just a street rider, I'm aware of the weak frame, wouldn't use it off reading. I just like a second motor for long trips, or to help cool one down. With two batteries, totalling close to 45 to 50 miles a trip, I feel it's a strain on the motor, having the second would push my range to 60-70miles.
I thought about the mid drive systems before, but I think it creates resistance with the xp motor while pedaling? Thats why I just wanted a front motor.

Ok, I get it. So the motor size difference on ebikes makes for much more cooling capacity on the motor. We also have so much more space on an ebike so the controller is larger to accommodate circuitry that among other things includes feedback from hall sensors in the motor that will throttle back amps if the motor heats up. Only happens on long uphill climbs on the Lectric so I doubt more than 5% of Lectric users have even noticed it happening. It was common for me to run the Lectric on mostly flats with a 30 ah non-stock battery at 20 mph throttle only for 60 miles or so non-stop. No overheating. I have about 6000 miles on the bike and the motor hasn't made any noises or issues indicating to me that it has any perceivable wear. At 5000 miles I took the motor cover off planning to clean & grease but it looked fine so I just put the cover back on.

But do you know of any hub motors for 20x3 size? I can only find 20x4s. I might sell the bike or try to find a shop to spoke a 20x4 to 20x3 one day. The original xp 1.0 was a 20x4 l, and people modified it easily.

I saw it on youtube at a ebike, esk8 ride group meet, but looked pricy, and appears to be only one in exteistance.

You actually want to check the rim width. Bike tires and rims are a different beast from car & lite trucks tires. 20" bike rims don't even measure 20" anywhere on them. Some 20" bike tires measure close to 20" in outer diameter very few are going to measure exactly 20" in outer diameter. A rim inner width between 40mm to 65mm would handle both 20x3 and 29x4 bike tires as a general rule of thumb. You can fit a 3" tire on a rim wider than 65mm but you would be starting to push the limits of bike handling. You also can fit a 4" tire on a rim that is less than 49mm but again pushing the limits of handling.
