Bernard Kiwia is from Arusha, Tanzania. He’s here at Maker Faire Africa as part of the IDDS group that has been building innovative devices for the last couple weeks in Kumasi, Ghana. Today he’s showing his device that he created from an old bicycle and some welded rods. It’s powered by someone sitting in a chair.
It cost Bernard about $45 to create the bicycle powered hacksaw and one day to fabricate.
Bernard’s been a bicycle mechanic for 3 years, and has been teaching students in Tanzania to fix them for the last couple. He was invited to IDDS and met a Guatemalan attendee that had some very interesting designs using bicycles. After seeing those, he realized that he could make similar tools and devices for the needs of people in Arusha.

Since that time, Bernard has created a windmill, cell phone charger, drill press and a pump – all working off of bicycle parts and mechanisms.
