Fitting emopeds on existing city charging grids

Looking at iniciatives like Betterplace, one might imagine that it makes sense to already plan how open source electric motorcycles like our e.Moped will fit existing city infrastructures. I am not sure if we will ever come close to a standard for all electric motorcycles but it is quite good to already start a discussion around this subject. It might be that a we will have to have a hybrid version before all houses get an own dedicated "vehicle charging outlet". 

The sketch above tries to exemplify such hybrid solution where our e.Moped gets two batteries, BAT 01 (see picture) provided by the electric charging grid provider, with a special socket that fit charging stations around the city (ex: Betterplace) and BAT 02,  just like any other battery today, that you can detach a take to your office for example, and charge on any power outlet. That way, you could be more flexible and get around possible situations where you don't see any charging station near you.

Image that by having such hybrid solutions, users could benefit also from battery switch station for electric motorcycles. Check this video of a prototype from Betterplace's battery switch station for cars.

Should we take that as a design requirement? How would two batteries of different management systems work together? should we think about developing guidelines for charging stations so cities could have access to this technology? Are there already examples of charging stations for motorcycles out there?

Flexible Box Frame - Multiple Configurations Sketch

Taking the idea of flexible adjustment points further, I sketched this the other day: 2 different motorcycle styles we could make with a Flexible Box frame. A MX configuration above, for riding trails and racing on the weekend, and a Scooter configuration, for zooming to the beach or taking the girlfriend to the movies.

I don't know yet how massive the Box module should be to handle all torsion going on while riding...we will need some engineering anyway in the future =)

Feedback plz...

electric components: Golden Motor, viva technical drawings!

I started looking closer to electronic suppliers, researching prices and availability. I bumped into Golden Motor, which supplies electric motors, batteries, controllers etc... as stand alone parts or Kits. What made me like them from the beginning is the fact of the availability of technical drawings, making it easier for us to design our e.Moped around their components.

We will need help later on defining which model of hub motor,battery,controller should we start with...anyone?

I leave here my excitement about suppliers that make available technical drawings for DIYers like us!

 

Flexible Box Frame

Just for fun, a frame concept with a fixed Battery/Controller Box where everything else attaches to. Box shall be designed in such way to enable any battery/electronics to be used. We would start with a hub motor to keep things simple. Fitting a pedal crankset would be awesome as well, leaving the rider with the option to pedal home when battery dies.

First MX/Supermoto geometry draft in Solidworks

It was time to start the works...by sketching the frame main measurements in Solidworks. I used an 24 inch wheel diameter for now. We can play around with the geometries to meet our needs. Also good to point out that we still haven't defined a concept for the frame yet. We are just puting up useful files for any direction the project takes, any ideas for a flexible frame concept? lets populate the discussion group... cheers!
