Plans for this build (3D Sketchup CAD):

FINALLY, the motorbike is finished. Sort of. I'm upgrading the front/rear suspension, and the hydraulic brakes over the winter. I don't feel the common components used on other e-bikes are suitable for the extra weight that this motorcycle is carrying in battery capacity (battery alone weighs 80 lbs). But it's a very comfortable ride, regardless. Not like a typical e-bike. Other minor cosmetic details could be better, as well, but that's a matter of opinion/preference I think. Other than that, I think this bike is great. I love it! Fast enough for highway use, better acceleration than most cars, and more than enough range for the avg person's daily commutes.

I just finished the plans, and they're now available for download. As mentioned previously, there is no step by step build guide for this build, just a .pdf with dimensional drawings and the 3D Sketchup CAD. It's not really a project for beginners, and I don't think experienced builders need me to explain step by step how to work the materials, so I kept it simple this time. But I did set up scenes in the CAD with dimensions for all of the components, so it would be worth while to get Sketchup (or use the free web version) and refer to the CAD for a better look at the details and dimensions vs the .pdf drawings.

DISCLAIMER: This is a prototype vehicle. By purchasing the plans, building and using the prototype as your own for personal or commercial use, you are assuming all responsibility related to that use (resale of the plans is forbidden). Please obey the rules of the road, and wear safety gear.
