Low-tech Solutions shows how to build a pedal-powered generator and controller, which is practical to use as an energy source and exercise machine in a household — and which you can integrate into a solar PV system. they provide detailed plans to build your own, using basic skills and common hand tools.

The bike generator and dashboard were designed and made in collaboration with Marie Verdeil as part of her internship at Low-tech Magazine. We could not find the technical information we were looking for, so we followed a trial-and-error approach. That was time-consuming and costly, but we gained insight and learned lessons. We made lots of mistakes that you can avoid.

The control panel can take different forms and use other tools and materials. We built a proof of concept with scrap wood and Meccano then strapped it to the handlebars with iron wire and some wooden blocks.
