Electric Bike Conversion Kit

Karl Gesslein / February 21, 2015 Several months ago I started looking seriously at creating ‘the ultimate fatbike’. I knew it had to be 2 Wheel Drive and I knew it had to be full suspension, but I had no idea where to start. Once I saw the Quigley Full suspension fatbike from Bikes Direct I fell in love. With a high-end component level the Quigly looks perfect for electricfication Before Doug’s 100mm axle conversion for the BBS02 had even come out, I was planning on mounting a BBS02 on this bike even if I had to grind down the BB and space out the chain-wheel...

Karl Gesslein / September 9, 2015 When planning and designing an ebike build one of the first questions that a builder needs to ask themselves is how much power do they really need?  A perfect build would have enough power to get up the biggest hill in your commute at the speed you want to go uphill at and would also have the top speed that you want to ride at available when you want it on the flats. Building a bike with more power than you need means you have to spend more and carry around has extra weight. Building an...

One of the hardest questions most builders have to ask themselves is which direction should their builds go in. Fat bikes are particularly difficult as a 26″ rim with a 4″ fat tire ends up being a larger Diameter than a 29er tire. This larger diameter means higher top speeds and lower torque no matter what motor/gearing combo you use. The problem with fat bikes is that they are a terrible design for high speeds. Running low pressure tires and tubes creates a lot of friction at high speeds that can greatly shorten your tube’s life. Larger wheels = less...

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...
