Electric Bike Conversion Kit

Karl Gesslein / March 5, 2016 This article has been swimming around in the back of my head for a while now. Since I am over $20,000 into the sport, and since I have spent the better part of my life being a Rock Punker I feel like I am probably the best-qualified person to write it. Most people’s experiences with e-bikes goes something like this. They discover Endless-Sphere and spend a bunch of time reading articles, then they look at people out there selling ebike kits and they decide to buy the cheapest kit they can get. They have done enough...

Karl Gesslein / February 19, 2016 Several times a week I get asked the same question over and over by loyal readers just like you. What mid-drive should I buy? Although it seems like a simple question, getting the right motor for your application can be a daunting task for the uninitiated. This article will help future mid-drive buyers make an intelligent and informed decision that will bring you years of fun and enjoyment. BBS02 750? BBSHD 1000W? Cyclone 3000W? Decisions, Decisions. This article is mostly for people who have already decided that they want to go with a mid drive. If you are...

Karl Gesslein / February 25, 2016 “Young fool. Only now, at the end, do you understand. Your feeble skills are no match for the power of the dark side. You have paid the price for your lack of vision.”  – Emperor Palpatine I wanted to do a mid drive build that would be dirt cheap and still work equally well both on single track and on the road as a commuter. In the end, I created a monster that performs well in both arenas, but is the master of none. The old school nuvinci N171 performed well even under tremendous amounts of power, but...

Karl Gesslein / March 19, 2017 Although last time I was in LA I swore I was never ever going back, here I am again at the Lunacycle HQ spending several hours a day sitting in traffic. How do people live like this? No wonder ebikes are so popular here in Southern California. People can get an ebike and commute on the bike paths along the ocean and avoid the traffic completely. If I lived here I’m sure I would do the same. I got my hands on one of the first prototype of Bafang’s 1000W Max Ultra Torque sensing mid drives and I was...

Karl Gesslein / March 3, 2018 The Ultra Max Ludicrous edition (2500W peak) fitted onto a modified FS fatty frame One of my pet peeves about the new torque-sensing 1000W Ultra Max drive unit is that there just aren’t that many frames for it available in the states. The original Bafang Max drive which only sported 350W of power has a totally different mounting bracket than the Ultra Max which means you just can’t fit a round drive unit into a square hole. While there are prebuilt ebikes on the market that you can buy already with the Ultra Max drive unit on it,...
