The ǷHΔδΦR TRANSFORM
We are excited to announce that ǷHΔδΦR Cycles is un-veiling its new electric mountain bike frame exclusively to the endless sphere forum. The ǷHΔδΦR TRANSFORM was designed from the ground up to be a highly capable downhill style electric mountain bike. Endless Sphere members will have the opportunity to order the first production frames at a discounted rate.
Our first creation was the EMXB prototype designed and built as our mechanical engineering senior design project, this is the evolution of that original concept...everything we learned from that first bike translated directly into improvements to this new model.
This new frame is tailored for those DIY'ers that are interested in a platform for a high performance off-road electric mountain bike. The frame is highly capable and is compatible with many different component configurations. The simple, yet versatile design allows for a mild or wild bike depending on your budget and goals. The internal volume of the frame has plenty of room which can easily house up to 35 Ah Zippy Lipos along with the controller and still have room to spare! Fit your batteries, controller, and even charger in the cavity. The frame is constructed of TIG welded chromoly that has been precision waterjet-cut, making a capable light weight and versatile frame. It has been designed to hold the batteries low and centralized.
Above and directly below is an example of the frame with components we selected to make a high performance down-hill style electric mountain bike.
Below is the frame and swingarm ready for anything you can throw in it or at it. Expected to be available late 2011 / early 2012.
