As if being a national champion cyclist and aerospace engineer for NASA weren’t enough, Dan Hanebrink had to go and design the Hanebrink All Terrain Bike. Hanebrink was tasked with an alternative to using skis by an explorer over 10 years ago and his mission has led up to this beast of a bike. This baby is suited for everything from snow and ice, to dirt and concrete thanks to its hefty tires. Suited with a 600 watt motor, it can excel up to 20mph. The bike also comes with a lithium ion battery that when fully charged can trek for 100 miles.
