I bought an Ebay belt drive kit for my Giant MB. https://www.ebay.com/itm/Belt-Drive...0CC-Engine-Motorized-Bicycle-New/124255715643
After getting the sprockets installed, which is just a swap of the pinion and wheel sprockets, I had installed the belt that came with it. It was a 1450mm loop and I had to use a tensioner on it.
Well that didn't work so well. Pedaling was OK, but when you pop the clutch, the belt tightens up on the bottom, which in turn fully actuates the tensioner, causing the belt to loosen around the drive sprocket. Back to the bench.
I measured around the sprockets and got 1425mm. Since belts are ordered by inside diameter i bought a 1410mm and a 1420mm. The 1410 fit just right. nice and tight. I had to roll it onto the rear sprocket. The tensioner isn't needed.
I went for a ride and was pleased how smooth and quiet it is compared to the chain. I ordered 2 more belts for backup.
When ordering the belts you want a HTD 5M length in mm. So mine are HTD 5M 1410. The width is 15mm. Tooth spacing is 5mm.
I got mine on Ebay. https://www.ebay.com/itm/HTD5M-Timi...var=563692173641&_trksid=p2057872.m2749.l2649
