it will take time to get to 70 but it can do it. the engine is the same 55cc that you get in a goped & the fastest iv been on a goped with the same engine was 75 kph.The thing with the goped is that it had a 10 inch back wheel running a 8 inch sproket now i need to get the same rashio on a 15 inch BMX wheel il need to run a 13 inch sproket and i dont think they make them that big so i need to macke a plan, just need to think a bit

You'll need to put the pedals back on for it to work as there probably isn't enought torque in the motor drag you and it for 0 to 70 on a single cog.
Another question - Where's the brakes

are you still gonna use the BMX brakes?

Have you looked into Stunt motorcycle sprockets? You will unfortunately have to run a bike chain as well ($$$). Or have one made up locally($$$$).
