I'm saddened that the bikes don't work for everyone. They're very useful.
I can drive them with relative ease, with an FPS of around 50-60. In the city or in areas where there are bumps and/or obstacles, I tend to slow down to avoid speeding right into those tricky light poles that materialize right in front of you. (

)
But on the open road like parts of Al Basrah's open desert, I put the pedal to the metal. Interestingly enough, the bike becomes easier to control, much smoother, when at full speed on these wide desert expanses. Maybe it's just me, but it looks like it turns cleaner. (Granted, it may be the looser movement of the FPS rise due to less objects being rendered)
Also, this may be a placebo, but I think pressing/holding Shift gives the bikes a boost like in a Humvee or Land Rover.
Drive safely.
