(ET) E-bikes

["Max Hall" <maxo iname com>]

You guys,

my students and I converted a small Honda to electric this year... check it
out: http://www.e-scoot.com/our_evs.htm

Some of what we learned: battery weight is a killer on a two wheeler, but
weight and range go hand in hand. (Fast bikes for short distances are
easy... going a long way is much tougher.) But it's relatively cheap and
it's loads of fun.

My recommendation, though, is a trike config. I think a small, rr wheel
drive car's front end matched with a single driven rr wheel is the way to
go.

I have been working on a tilting three-wheeled electric, the Maxion.

** We should be careful not to get too far afield on this list... it's for
ETs. Email me if I can help or if you have questions about e-projects. **
