The MARS-ONE description mentions that it carries 2 motorcycles. I assume that they are dirtbikes – to be used for recon and liaison duties. However, these vehicles are not described.
The following is an attempt to rectify this omission: the MP Electric motorcycle
This is a real-world dirtbike. It’s manufactured by Zero Motorcycles of California and uses several components that were originally designed for mountain bikes (in fact, this machine could be described as an electrically-powered mountain bike)
Specifications
Weight: 140 pounds (63.5 kg)
Max speed: 50mph (80.5 kph)
The performance of this bike is equivalent to a 125cc dirtbike.
A single charge of the battery will give a range of 40 miles, but the battery packs can be ‘hotswapped’ in mere seconds and fully recharge in about three hours.
