Sorry about the ramblings before. I'm just happy to know that you have two and Walmart brought back the Hyper Motobike 36-volt.
The motor I remember it originally had was a brushed, 250W 24v. Mated to a 250W 26V controller with a side plug for the charger.
I remember getting an e-bikekit.com, heavy brushless direct-drive motor. Looking back I should have opted for a rear brushless, 36V 350W motor. But the 1000Ws and braking regen is what attracted me and skewed me off.
But technology and manufacturing has improved. Mid drive is the way to go.
Now I'm savoring for a gng mid drive motor kit. 350W 36V(Overvolted to 48v). And somehow get it to fit the oval hole under the seat.
The cheapest upgrade is the rear Shock. Get a mini moto and around 800lbs of strength. If not the rear swingarm is going to bend and bend your rear disc brake rotor.
