GPR1 Electric Motorcycle
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.
