Video: Ultra-Customized Rwandan Bicycle Taxi

Not all inventiveness is utilitarian (or, business can be fun and fun can mean more business…).

Such is the case with this video by Eric Kabera – the maker of the genocide film “100 days” and inventor of Hillywood - Rwanda’s version of Hollywood. In it he interviews Alphonse Maniriho, an unschooled young 23 year old with an idea: take the classic “Black Mamba” bicycle and completely customize it.


Being a smart young businessman, Alphonse uses his unique bicycle to his advantage, getting extra business from young men who want to ride with him so they can listen to the beats along the way.

A quick list of customizations:

  • A watch, set in an old shoe polish can
  • Lights, that flicker in the front and back at night
  • Radio, for his passengers to listen to

A little background on what being a taxi man is in East and Central Africa is probably important for most who haven’t been to Africa. They have a seat on the back of the bicycle and use that to take passengers around. In East Africa they also go by the term “boda boda” (because they originated around the border of Uganda and Kenya).

Bonus: at about the 8:30 minute mark there are some nice videos of the wooden bikes used around Africa.

Hardware Hacking: Handmade Tools in Africa

I’ve written about handmade tools in Africa before, but it didn’t generate a ton of interest, so I’ve not followed-up on it very much in my travels. I was really happy to see that another person was intrigued by this though, Kevin Kelly has a post where Tom Ritchey, master bike frame builder, sent him pictures of hand-made tools he spotted at bike shops in Rwanda.

Fabrication is an important skill in developing nations. Along the whole process you see reuse taking place, even down to the tools being used to create the items in question.

A Kenyan micro-entrepreneur recently told me:

In the sixties, during the space race between Russia and the U.S.A the Russian Engineers, when told there was no more money for the budget philosophically said “now we have no money then we can think” and they were able to be tremendously creative when compared to the Americans despite the limited funds at their disposal. This is the same approach I use in my initiatives.

As I’m not the only one who thinks these are pretty cool, I’m digging into the AfriGadget Flickr Group to pull out a picture that I never published here on the blog. These are small engine repair tools built to work on motorcycles, generators and lawnmowers (among other things):

Modified Small Engine Repair Tools

And finally, a video of Bernard, one of the local small engine repair guys in Nairobi (who’s shop has since disappeared) talking about how he makes some of the tools:

Re-use in the (unofficial) Kenyan Ironworks Industry

Gikomba is a part of Nairobi that is well known for metal working. I had been meaning to come this way for a while, and today afforded me the perfect opportunity to drop down into Gikomba and see what kind of enterprising activities Kenyans were up to.

I ran into a George Odhiambo, a bulk fabricator of everything from wheelbarrows to chisels. The chisels caught my eye, primarily because one of them looked a lot like a shaft straight out of a Land Rover. It turns out that they reuse multiple types of iron for their goods, including leftover pieces from old vehicles. Nothing goes to waste here.

Even more interesting to me (probably because it moved and did stuff with fire), was the bicycle-turned-to-bellows that kept the fire going that would heat the metal rods. It’s a fairly simple, yet ingenious contraption that utilizes old materials with a little bit of engineering. The thing runs all day, every day too, so it’s made to last.

The chisel pictured below is a stone chisel, used in quarrying and squaring stones in the quarry’s dotting the country (most houses in Kenya are stone). They cost about 350/= ($6) to make, and sell for about 650/-= ($11).

African Toys - A Pictorial

We hope you enjoy these pictures of toys from Kenya and Ghana. They are a sampling of the pictures on the AfriGadget flickr group. The materials used to make these toys are scrap metal, tins, wire, and pieces of leather.

The Bamboo Bike project

The Bamboo Bike, an endeavour that aims at building bicycles in a sustainable fashion using bamboo as the primary construction material, is a joint project run by Craig Calfree of Calfree Design, a high tech bicycle design firm based in California and The Earth Institute at Columbia University.

The bicycle is the primary mode of transport in Africa and it is used for everything from personal transportation to moving medicine and the sick to hospital. Sadly, the design used in most of Africa has not changed for the last 40 years to take into account the different ways in which the bicycle is used. In fact, most bikes in use in most of Africa today are based on a colonial British design tailored to individuals travelling short distances on smooth roads.

Bamboo Bicycle Project - Bike Assembly  Bamboo Bicycle Project - The Bamboo Bike

While making bike frames based on bamboo is not a new idea, most bamboo frame designs simply use bamboo for construction material in a traditional bike frame design. Leveraging the unique properties of bamboo such as its strength and flexibility to meet the specific needs of populations local to various parts of Africa is one of the primary rationale behind the Bamboo Bike project.

The team working on the Bamboo Bike project in the US, Ghana and Kenya among other locations have a interesting blog (last updated in the summer of 2007) that chronicles the struggles of the project team while on site in Africa.

Project gear including Bamboo Bikes and clothing is available on the Bamboo Bike and Calfree Design websites.

One Man, an Airplane and a Hummer

Mechanic and Plane MakerThere’s a really interesting story about a man in Kenya who claims to have created a plane from scratch.

Using a Volkswagen beetle engine, and aluminium sheets for the body, Mr Gachamba made a single seater plane.

He tested it out at an airstrip in Nyeri and sure enough, it took off. Caught up in the excitement of the minute, he decided to fly to his home in Mathira.

A few minutes into the ride, he noticed the engine was overheating. He decided to turn and in the process the low flying plane struck a tree top and crash landed. He was injured in the leg and has had a limp since.

(Read the rest of the article)

I’d love to see pictures of this plane, though I’m doubtful of there being any as this happened in the 70’s. Either way, a fun story. Right now he’s building his own Hummer from an old Datsun engine and “wheelbarrows, wheelchairs, metal pipes and other vehicle accessories”. At 75 years old he’s not slowing down at all!

Mubarak Abdullahi’s home-made helicopter takes Nigeria’s Kano Plains by storm

Yahoo! News (among other sources) carries a story from October 21st about Mubarak Muhammad Abdullahi of the Kano Plains of Nigeria who has built a working helicopter over the last 8 months using scrap aluminum and parts from a Honda Civic, an old Toyota and from the remains of a crashed Boeing 747.

This inventor has had no formal training in flying and his helicopter has never flown higher than 7 feet of the ground. In an interview, he talks about how the machine works:

“You start it, allow it to run for a minute or two and you then shift the accelerator forward and the propeller on top begins to spin. The further you shift the accelerator the faster it goes and once you reach 300 rmp you press the joystick and it takes off,”

Mubarak is ambitious however and has embarked on a new project to build a better helicopter that will be able to make 3 hour flights. He hopes to get support for his project from the Nigeria Civil Aviation Authority (NCAA) and other Nigerian government bodies.

Where the World Sees Junk, Africa Recycles

This post is dedicated to Blog Action Day, where thousands of blogs around the world unite to talk about one theme. This year it is the environment.

Recycled Sheet Metal Crocodile

Simon Mwangi calls himself a mabati (sheet metal) blacksmith. He takes junk and creates beautiful metal animal sculptures. If you happen by his roadside shop on Ngong Road in Nairobi, you’ll see a number of crocodiles and if you’re lucky, a full sized giraffe.

If you’re in the market for a crocodile, which he sells primarily to hotels, be ready to pay 30,000 Kenya Shillings (about $450). They take about one week to make.

A Successful Business Entrepreneur in Africa

What’s remarkable about Simon, beyond the actual artwork that he fabricates, is that everything he does and works with is made from left over metal junk. Even the welding machines that his team uses are made by the team from leftover metal plates and copper wire. (See an example of the welder at this earlier AfriGadget post)

This is an excellent example of how Africans reuse and recycle to meet their needs. Many times their ingenuity creates thriving businesses, proving that entrepreneurship and environmental needs aren’t mutually exclusive.

Made From Scratch Model Airplane

Phillip Isohe is a metal fabricator in the jua kali, non-traditional industrial sector, in Kenya. In his spare time he builds models of airplanes and buses. This seems to be an extension of what many of us did while growing up in Africa - building wire, or tin can, cars. What’s most interesting is the excruciating attention to detail that he puts into each one. In fact, they each have motors with working lights, steering, engine and interiors.


Phillips model airplane in kenya

Phillip had just sold one of his buses, so the only other one I have a picture of is only half-built (picture). However, he did have a finished and working model airplane. It was amazing to see how each piece, engine included, was built from scratch. It’s not every day that you see this kind of detail work on hobbies, no matter where you are in the world.

The models take him 30 days to make and goes for about 25,000/= ($370). That’s likely just his “starting price” though, and they probably sell for a good deal less when he really wants to move it.

Here’s a short video of the model plane:

Home Made Welding Machine

Being on the ground in Nairobi makes it a little easier to find good AfriGadget stories. I took a walk down Ngong road, an area with a lot of shadetree mechanics, wood carvers and metal fabricators. The first place I stopped at had a home made welding machine.

Simon, the shop owner, showed me a couple of the machines and gave a video tour of how it works. He’s a prime example how an entrepreneur in Africa will figure out ingenious solutions to meet local market demands. The welders sell for around 14,000 Kenya Shillings (just over $200), but fabrication costs only a small fraction of that.

Below is the video and some pictures. (Another video will be uploaded later, connection speed issues preclude me uploading another one right now).
