I have worked this out i am able to turn a 200MPH landspeed Bicycle into a uphill as well
So this is it instead of that awefull heavy unwanted weight of this radicale BMX
type of Bicycle use high grade Aerospace alloy for the frame lighter
for the gear changes instead of changing the top gear here we go

So reverse pedal low gear for hill climbs then forward for downhills
well aabout the size of those front and rear moto cross tyres well
look at some of bicycle with massive fats there no different
