[1] According to Logos Technologies, the objective of the SBIR is to deliver a low-acoustic, highly maneuverable vehicle that can carry American Special Operations personnel and their equipment behind enemy lines, over difficult terrain, without being detected.
[2][3] The SilentHawk design incorporates an all-electric RedShift MX dirt bike, produced by Alta Motors in Brisbane, California, and a multi-fuel genset originally developed by Logos Technologies for a separate unmanned parafoil project.
[4] By combining the Logos Technologies genset with the existing 5.8 kWh Alta Motors lithium-ion battery pack, designers contend that they can extend the total range of the bike and also allow it to recharge on the go.
[6] SilentHawk's genset was also designed to burn whatever fuels might be found in the field, including propane, gasoline, diesel, JP5 and JP8 jet propellants.
[11] As part of a second Phase 2 SIBR, Logos Technologies is scheduled to produce two SilentHawk bikes for DARPA: an electric one with all-wheel drive and a reduced weight hybrid-electric system with a modular architecture.
