Hey Jeff, Make sure that Franken'ceptor doesn't bounce around too much on
that trailer ride:>) Do you plan on coming out to Hopland this year? I hope
to have another bike built by this summer, hope to see ya then! Bob

The 250 is a good start because weight is the the electric vehicle
enemy. Your goal of 44 miles on a charge while trying to keep the bike
weight down is going to challenge the storage issue. Some folks here
have used older technology nicad single cells as they have some weight
savings, and since they are individual can be arranged easily though
they are liquid electrolyte and not sealed. To get low weight/high
energy density that Lithium Iron or NiMH (which are okay on the
environment) would be the only way to get the range. AGMs as I have
used (55Ah - 72V) have netted only 21 miles of mixed mileage, 60-40
flat-hills here in Colorado. I am carrying 228lbs of batteries, or
roughly just over half the vehicle weight. This is on a 84 VF500.
Lithium Ion and Lithium Poly both have safety issues and bad
environmental Karma.
There is a Chinese company that occasionally posts on EBAY Lithium
Iron battery packs. You may be able to come up with the physical specs
of the space you have to store the batteries and they can configure
the battery pack for that space.
BTW List viewers: I have been asked by Adams State in Alamosa, CO to
go to their Earth Day event and talk to the students about electric
motorcycles. I hope to have an electric bike with me as well if I can
borrow one for the event. I will have to trailer the The
Franken'ceptor since it is 4 hours away. The reason I bring up Earth
day is there may be an event near you worth tooling over to on your
electric motorcycle, maybe gather some potential converts, or give you
the opportunity to do a conversion for someone else (make a few $ for
the next project?). Or just bask in the revelations "Uh I didn't know
Honda made an Electric Motorcycle."
Cheers

Hello,
I'm gathering information on how I to build an EM. I've got quiet a
few
motorcycles. (Actually have 9 running bikes and 2 other parts bikes) And
it
struck me that I've got a rolling complete (minus engine) EX250 that
would
make a good candidate for a EV conversion.
My goal is a EM that I can commute on. However, work is 44 miles
away.
I'm certain I could charge when I get there and be ready to ride back
home.
The route is mixed with some rolling hills, but about 60% flats.
I've been reading up and I've read about regen. I will have a section
that is stop and go traffic (traffic lights). And a section that is
about
20 miles of the straight shot with one stop. (rolling hills too) So I
think regen is definitely a requirement.
At this point in time, I need guidance as to what controller, motor,
and
batteries to use. And the feasibility of the entire project. I have a
machine shop and since the EX has a steel frame, welding isn't an issue.
I'm looking at the D&D Sepex motor and a Alltrax controller. Also is
there
any sources out there for used/rebuilt motors/controllers? What's the
feasibility of a deepcycle battery from a local store (to save shipping
costs of multiple batteries)
Thanks,
Andrew
