That engine is equivalent to over a 3kw electric motor. The cycle components are likely to struggle with that unless upgraded. Tyres and bearings are the first components that will likely suffer but equally a regular cycle rim won't take kindly to hitting potholes at the speeds it could muster. It would go over 50mph with that amount of power. You'd need approximately a 17:1 gearbox to reduce that to get to appropriate rpm at the wheel for 50mph (26" wheel) and there's no way regular cycle chain will hold at that power, you'd need something beefier or a moped type variable belt drive. I appreciate that just because it will do 50mph+ doesn't mean it has to do that but I'd suggest that once you get above 30mph and 1000W you start to move away from std cycle components and move to moped ones or, probably much more expensively, cycle ones specifically designed for high power ebikes.
There's also local laws to consider and I have no idea on those in any area of the USA. I'd be surprised if any state would allow such an engine to be attached to anything without meeting a myriad of laws before being allowed on any road.
