During its inaugural “Celebrate the Sun” community event held in Munich today, Sono Motors debuted the production design of its upcoming Sion solar EV. Not to be outdone, Sono Motors followed up with an additional world premiere, unveiling its new “Solar Bus Kit” that can be retrofitted on existing city buses to help reduce carbon emissions.

Last month we featured an awesome DIY solar cargo trailer that an Electrek reader built for his electric bike. Just in case you needed any more proof that our readers are some of the handiest and most clever eco-DIYers on the planet, we’ve got another impressive solar-powered electric bike to show you. This time it does double duty as a school drop-off vehicle for the kids and a grocery getter.
