I created Gravity Worx in 1989 when I machined my first carbon fiber lug molds for a mountain bike frame. Back then mountain bikes were rudimentary and made from steel. I was young and fit, and I raced everything I could ride. Over the last 30 years, as materials and equipment progressed, I also became older and much heavier. After designing and building the lightest frames, wheels, and components, for the last 30 years, I found myself 48 years old and 289 pounds. If I didn't make a major change, I was going to die from heart disease or some other major medical issue. The problem was, riding where I live requires significant climbing at high altitude, and I just wasn't up to it anymore. The only thing that was going to meaningfully get me back on the bike for real exercise was going to be an e-bike. I looked at what was available and I wasn't impressed. There were some great commuter bikes, but no real mountain bikes with a motor and battery. Nothing capable of the type of riding I do, big technical climbs with long descents. I needed a long travel full suspension e-bike with a super strong and light frame and the most capable components. I built the E160FS to be that bike. It allows me to do long rides, with my significantly lighter friends, over any terrain I choose. It will do the same thing for you.
