Hey everybody. Bike is for sale, I have a few other projects brewing. It's done and ready to ride, just needs the gas tank painted. More info here: http://www.dotheton.com/forum/index.php?topic=74795.0

For sale is my custom built electric Ninja 250. Fully street legal and ready to ride. The last thing that needs finished is the gas tank, it's primed and ready for the new owner to put their mark on this bike. Here's the basic specs: Top Speed: 87 mph (that's the fastest I've gone, but I ran...

That photo was taken with the clip-ons, which lowers the bike by a few inches. Here's the bike with the stock bars, I'm going to stick with these. When the bike is on it's side stand, the leading edge of the battery is about 5.5 inches off the ground.

Lots of little work left to do, but I accomplished the task of getting it rolling before I have to move at the end of the month.

Sorry about the photos, I was using google photos and they changed the way they generate their urls. Should work now.

Battery is completed, all of the powdercoated pieces are assembled. Still waiting on my painter.

Back on this project, sorry for the lack of updates. The frame, wheels, and all that have been powder coated. Also have a bunch of parts out to get painted and the seats been upholstered. Final assembly starts early next seek after the painted parts are dry. Lots of photos then.

Hah, I have some new Pirelli MT75s on the way to take care of that. Thanks for the comment though, it's something I was extremely concerned with initially (the frame, not the rock hard bald tires).

I've reviewed my engineering with an aerospace engineering consultant. He deemed the battery pack and motor assembly as structural. The construction of the batteries is unique, they have solid 6061 aluminum spacers in the corner, and the pack is held together with hardened steel 5/16" hardware...

It's like I'm going backwards.

Yeah, the torque is pretty wild. Climbing hills on this thing is a breeze too, it just keeps pulling. Electric drivetrains are really great, it's just the damned batteries holding everything up.

You mean something on the bike or something at my house? Electricity is so cheap for me, I'm not really concerned. But I have also seen a bike with solar "fairings", made by a member of elmoto.net named Tony. He had them on linear actuators so he could pop up the fairings electronically...

Although it isn't quite as active as this forum, there are lots of cool conversions on: www.elmoto.net www.diyelectriccar.com www.endless-sphere.com That's where the EV nerds hang out. These are the kind of guys who build their own motors, controllers, and chargers. Thanks for the kind words.

Regenerative braking is much better with an AC motor. Most decent brushed DC motor controllers don't offer a regen option, but there are some questionable Chinese controllers that do. AC motors are great, they're brushless and virtually maintenance free, but require more expensive controllers...
