Peter Kahugu of Banana Hill just outside Nairobi makes a living using his bicycle.
And no, he is not a professional cyclist.
AfriGadget reporter Afromusing and I had an opportunity to interview Peter who has modified his bicycle with a belt, a set of tensioning pulleys and a grinding stone to make it a knife-sharpening machine. By kicking the bike up onto its stand and engaging a gearing system, he is able to use “leg-horsepower” to drive a grinding wheel and sharpen knives while “on the move”.
Peter has been at this for 2 years now and he makes about Kshs 500 ( app. 10 US$) a day by riding his mobile workshop from client to client sharpening all their knives as he goes. The grinding stone he uses has lasted an astounding 2 years and he has had to replace his drive belt a couple of times but that is as simple as cutting up a long strip of rubber from an old car or bicycle tire inner tube.
Be sure to click though on the image for video on YouTube of the Peter and his bike in action.

officina. Sul manubrio ha una pietra per molare collegata ai pedali con una cinghia di trasmissione. Peter va di casa in casa, di baracca in baracca, di slum in slum, guadagnando ogni giorni in scellini quasi l’equivalente di 10 dollari. Questo è il sito, questo Peter all’opera ( basta cliccare sul video di YouTube)

about this, but it’s still good to read: this columnist thinks that in the UK the hassle of cars is so much greater than the benefit that it’s hit a tipping point and people are making changes. Okay, and another link from the Xtracycle forum: Knife-sharpening bicycle. Not for novelty… for real.

It is a very common device in Basil’s small cities. Tho be honest, I grew up in Rio de Janeiro. When I was just a little child this kind of device was very common. This photo bring me very good memories.
This is great, I grew up with this gadget back in the fifties in India, and the last I saw of it was in the ’70s when I moved to the USA. I remember being amazed at the ingenuity involved and also huge sparks would fly during the sharpening process, which looked like fireworks to us 8 year-old boys. Thanks for the story !
Amazing, now that is entrepreneurial enginuity for you. Don’t wait for it to come to you go get it. I wonder how much more can be accomplished with his kind of thinking.
This method was still fairly popular in the old districts of my hometown (Poznan, Poland) when I was growing up, however on my recent visit I learned that the last old fashioned knife sharpening biker passed away last year.

This contraption has been used in India for decades now. I remember seeing this on the roads as a small kid. When I ask my Grand dad he tells me he has seen it as a small kid too… probably for a long time indeed
Interesting to note that the bicycle actually comes from China and that the Chinese have presumably indepently developed their own sharpening procedure for their knives (n.b.: almost all knifes sold in Kenya are also Made in China, no matter if they come with a Made in Germany Logo). I wonder if they use the same system?
The knife-sharpening bicycle is a perfect example of “added-value”

Comment from Mr B robinson 29 March 2008 - 4:29 pm - :
Was having a discussion about this apperatus with my friends, wh would not believe
[...] The site contains such amazing examples of innovation fostered in most cases by extremely severe constraints. Imagine building a flying helicopter from old scrap machinery, how about developing a dual cellphone SIM card in order to access multiple carriers, or maybe generating self sustaining renewable energy in places where the power grid will not reach? There are so many mind boggling projects on afrigadget. The one that I found most inspiring was a very simple business idea, The knife sharpening bicycle. Such a simple genius idea that produces approximately $300 a month in revenues. What constraints do you face right now in building your information business or product? Embrace the constraints, find solutions that will address those constraints. By doing so you might find that yourself generating some really good revenue. The knife sharpening bicycle. [...]
