But they're not the same size. Hoverbikes have twice the crew capacity and a vast improvement in engine power. In addition hoverbikes cost $5K while road bikes are a mere $2K (engine upgrades not included). That's right. If you thought a dozen hoverbikes was good, try 30 machine gun/rendor plasma toting bikes. That's a lotta dakka! Despite being a terrible gun against UFOs, Road bike guns will provide a HUGE increase of firepower on the average cityscape. These bikes are all over the place and there's pretty much one or two always active somewhere.
