Hi Everyone,
I just posted some pictures of a new EM project I am working on. Actually, it's been underway for a while, I have just been too busy to post pictures and share. http://electricmotorcycles.net/modules/xcgal/thumbnails.php?album=50 I am working with Jeff Patterson at Patterson Cycles here in S Florida on a new bike. Last year he built a gorgeous custom frame electric street bobber using the wheels off of a '08 Road King. There are pictures up on the EMNet gallery. I loved the bike at first site, even before it was painted and finished. He has built another frame, identical to the first one he built, that I am working with on building up. Jeff has done all the fabrication on the frame and getting the rolling frame finished. I have been helping out where I can on some of it, but Jeff is a real master and artist when it comes to metal work. The bike is using a front end and wheels off of a Sportster and forward controls off of Softail. I put a new Metzler 160 tire on the back and Metz on the front. As far as electrical parts, the batteries are the new Discovery EV24A batteries. Discover is the EV/traction battery line from Enersys (makers of the Odyssey batteries). 6 of them in series for 72VDC. The controller is the Alltrax 7245 72V 450A controller. Motor is a custom 7.5" DC motor from the motor god himself, Jim Husted at Hi-Torque. Battery charger is a Zivan which will be mounted on the bike under the tank covers. Jeff Patterson had originally gone with a stock 6.7" motor on his bike, however, it was just too small and got too hot. After working with him on testing it, I got him in touch with Jim Husted who built up a 7.5" series wound 8 brush motor. That was just the ticket. The new motor was 30lbs heavier, but the perfect motor for the bike. Jim built another 7.5" motor for my bike, but with slightly different field coils. We are going to compare the two motors on the bikes to see which one runs and performs better. When it's finished it will weigh right at 620-630 lbs and will have a range of 40-45 miles, which is what Jeff's bike is getting. Florida is pretty flat and we don't have any hills to worry about! I'll post some more pictures as work progresses; we are trying to get it running before next weekend when the FLEAA has the Battery Beach Burnout (www.batterybeach.com <http://www.batterybeach.com/> ) See ya, Shawn
