How can I purchase a display for this unit ?

The Electronic Speed Controller provided doesn’t provide the needed display wires to install a lcd monitor, although I didn’t feel it was necessary for my Razor Ramber 12 upgrade conversion. Sometimes simpler is better. My little scooter is insanely fast with gobs of torque even with a 220lb rider and it WORKS!!

What kind of connection port does the motor need to the battery?

So the kit itself comes with a block which has 5 terminals on it 3 in the middle which are for the phase wires and on each the left and the right side there is a terminal for the positive in the negative. On each terminal that come with a nut. The wires coming out of the controller just have a standard ring connector on each of them which are extremely accessible everywhere can even be made at home if need be. Personally I cut the original connectors off to replace them with XT90 connectors which can be found here on Amazon and I replace them for the longevity, durability and how well they work against water / corrosion.. -Good Luck & enjoy riding!

Is the controller 30a or 45a? Will a 48v 30ah battery good for this kit?

Hello sir, 30Amp. Yes, the 48v 30Ah battery is fine.

Whats the center hole size for the T8F sprocket wheel?

Im assuming you are talking about the small tooth sprocket on the motor.. you don't really want to mess with that.. the larger sprocket has about a 4inch hole in center. I got lucky and had a free wheel gear that bolted right up. But it's tricky retrofitting the sprocket. Alot of people weld them to bike sprocket because bike sprocket fits bike wheels.. I found a lot of good wheel parts at marine trading post that sold all kinds of stuff for boat trailers. I found multiple wheels that sprocket would mount right up to with just bolts

Pretty freaking decent

I hooked this 1000w motor up to an apro transit scooter (razor ecosmart metro) had a lil bit of fabrication and you need 4 lithium batteries to run it. But this thing runs like a raped ape. I pop wheelies when I take off. In 3rd gear I'm hitting about 45mph. 2nd gear about 38mph. Definitely worth it. I've purchased 2 kits so far
