The GPR1 is an electric
motorcycle conversion built by Maxdon Electric. It
is based on a Derbi GPR50 chassis.
Although we have had many requests to
purchase GPR1s, we are
not currently selling motorcycles. We are using the GPR1
as a testbed for components we are developing that
will
enable high-performance electric motorcycles to be available,
cost-effective, and refined. For those of you who are interested in
immediately
purchasing an electric motorcycle conversion or a do-it-yourself kit,
you will find many resources on the web.
