Top 10 Fast Electric Bikes-#1 Liveforphysic’s “Death Bike” 80-MPH


Contrary to popular opinion, the fastest electric bikes in the world right now were built in  garages, not in factory workshops. Maybe its because companies are not interested in making illegally fast electric bikes because of liability, maybe there isn’t enough profit in making expensive and fast electric bikes, or maybe companies lack innovation and are waiting for individuals to make the bold steps forward. For whatever reason DIY garage-built bikes right now are the fastest electric bikes on the planet. I can put it this way, when Specialized announced last month that they were releasing the “worlds fastest electric bike” with a 25o watt motor, there were chuckles heard from garages everywhere. Some of the bikes on this list put out 200,000 watts. And racing any of these bike against the Specialized would be like racing a Hyundai against a Formula 1 car.This is a list of the 10 fastest electric bikes that we know of right now. No marketing BS here.  To qualify for this list, the builder must have shot a Youtube video that illustrates the claimed speed of the electric bike. As we know the electric bike world is full of exaggerators…DIY builders being no exception.All the people on this list are respected builders, and are named by their Endless-Sphere forum handles. Endless-Sphere is the hang out spot for DIY builders and hot rodders. On this list  are some of the biggest names in the DIY community.There are a few (very expensive)  commercially available E-bikes that would make it to the middle of this list, but we have excluded those for now and will celebrate  those instead  in this  story… Top 10: The Fastest Commercially Available Electric Bikes.This here  list is to honor the achievements in the DIY community:

#1  Liveforphysic’s “Death Bike” 80-MPH

Liveforphysics, tired of frying fragile and lightweight RC motor setups, has discovered a magical combination of  massive axial flux motors intended for E-motorcycles, Sevcon controllers, and Nano-Tech Hobby King LiPos strapped  onto a custom built non-suspension frame. He is achieving speeds never seen before on an electric bike, all the while keeping his bike’s weight down under 200lbs. My favorite video of his is of the first carnation of the “Death Bike” which he built (in 7 days time) specifically to win a race I was putting on last summer called the “San Francisco Hill Climb”. Here is the crash that ensued and was caught on camera:
“Pinky”  was sold and shipped to a wealthy Hong Kong business man and  Liveforphysics would go on to build faster and more powerful versions of  what he would now call the “Bicycle of Doom” culminating in track recorded speeds of 80-MPH and cranking power levels far exceeding 100,000 watts (not a misprint !!!). LFP would win a few races, but is known more for smoking countless electric motors on race day. Says him: “I do tend to lean on things a little harder than most folks.
Liveforphysics now works for Zero electric motorcycles, and was instrumental in building the100-mile range 2012 Zero battery pack. In his off time, LFP’s passionate hobby is building the fastest electric bikes (with pedals) on the planet. He is #1 on our list of most influential E-bike people. In his spare time he rides around town on his beast which he claims is mild mannered, efficient, and controllable when not pinning the throttle wide open. Liveforphysics is a brash display of electric bike technology…and a breath of fresh air in a community dominated by more conservative and slower thinkers.
