Ray Wong, see EVALBUM, check under Motorcycles, has the Comet-Hoffco snow-mobile cvt. I am using a smaller Comet-Hoffco 330 CVT. With no springs and stock weights I am losing RPM through late full engagement... the clutch slips so I am not utilizing the full power band and going into 1:1 ratio. I have new weights coming in next week to engage the clutch earlier. The 330 is rated at much lower power than the Perm 132 I am using can output but I figure the engineers always overbuild (I have seen more than 25 years professional experience of this), so I will see next week. My EMC is alive and well, getting me back and forth to work at 40mph tops on bac streets, 3.9 miles each way, no charge in middle of day. I snagged some solar panels that could not be sold (donation from work) and hope to have a solar charging station set up at work (luckily I work for a green company and am in such a sunny state (CO)!!!). My bike is the Franken'ceptor VF500 Honda. I agree on finding a frame that can carry the batteries you want to use. Try not to alter frame geometry, think of using saddle bag positions for two batteries to even weight distribution. If you can avoid mounting motor on swingarm you lower unsprung weight. If you build it too heavy then you will lose the fun of the motorcycle, agile, nimble, etc. I am using 55ah AGMs, 72 volts, 300amp Alltrax, 6-6 amp onboard chargers, Vicor DC to DC converter.
I am going to be showing the bike at a couple of Renewable Energy fairs. One in Arvada,CO on June 2(?), and there is something in Boulder in late May. I am going to be working the the Midwest Renewable Energy Fest (fair), would like to bring the bike but I am flying in. That would be a blast. If anyone is going to be out in the Denver area and wants to see my bike let me know. I am going to try to get to another event somewhere within easy trailer range this summer, ideas? Just have to finish building the trailer in my garage!! lol Jeff -----Original Message----- >From: Johnathan Vail <[EMAIL PROTECTED]> >Sent: May 18, 2007 8:08 AM >To: ElectricMotorcycles <[email protected]> >Subject: Re: [ElectricMotorcycles] Re; EM Conversion question > >compton wrote: >>> I'm looking to build a bike that has a 100mph capability and a 100mile >>> range. >>> >>> where I want fast starts and don't need the range (surface streets), and >>> other days where >>> I need to commute (freeway), and need the longer range. >>> I think by keeping the tranny I can get the fun starts in the lower gears, >>> and get better mileage with the taller gears. >>> >> >> To some extent this is true.
