Jackton Achola runs a bread supply service in Kenya. He gathers the loaves, locations them into vibrant pallets, and stacks them excessive, above his head, on the pannier of his Buffalo bike. He then secures the load down with two rubber cables, and pedals out throughout his neighborhood in Kisumu.
On one journey, Achola can distribute sufficient meals for round 480 folks. “I’ve finished it for thus a few years,” he says. Not too long ago, one thing has modified.
Achola is considered one of eight testers in his nation who’ve been trialling World Bicycle Reduction’s (WBR) newest Buffalo mannequin, geared up with its new AK2 system – a drivetrain with two chains. It’s a revolutionary idea, one which took two years to develop, and has been patented with the assistance of US components producer SRAM.
The thought, WBR’s Michael Kelly explains, got here after feedback from testers like Achola, who had been utilizing the earlier singlespeed Buffalo bike. “One of many items of suggestions was the need so as to add a gear to the bike whenever you’re driving beneath a heavy load,” Kelly explains. “That was kind of the dream behind it.”
The double-chain drivetrain is discovered on the Utility S2 Buffalo bike, the most recent mannequin of WBR’s flagship product. Since its launch in July, it has undergone hundreds of miles of testing, and gained design awards at bike exhibits. Now, it’s being rolled out into communities.
Jackton Achola has been testing Buffalo bikes for greater than a decade.

“The philosophy of the Buffalo is that you’ve got parts which are going to outlive the challenges,” Kelly explains. The place WBR operates in Sub-Saharan Africa and South America, such obstacles embody tough terrain, excessive warmth, and the necessity to bear heavy cargo, usually exceeding 100kg.
“You’ll be able to’t have exterior derailleurs which are going to get gunked up or broken, after which not have the flexibility to service these whenever you’re in these distant environments,” Kelly continues. “The standard derailleur methods and different mechanisms simply aren’t lasting, proper?”

The thought for the two-chain system got here from an engineer at SRAM, an organization established by the founders of WBR. “These are the fellows innovating for riders on the Tour de France,” says Kelly. They’re additionally innovating for riders like Achola.
So how does the two-chain system work? “Primarily,” Kelly begins, “you will have these two completely different chain rings which are at completely different tensions. What we had been capable of do was engineer a mechanism that permits you to, by way of a backpedal shifting movement, trigger the freewheel to shift from one chain pressure to the opposite.
“We had been ready so as to add this additional gear with out including any sophisticated exterior derailleur or wiring.”
The bike is made on the Big manufacturing unit in Taiwan, and shipped to WBR’s seven programme nations: Zimbabwe, Uganda, Kenya, Zambia, Malawi, Tanzania and Colombia. The price of one bike, from the extraction of its supplies to supply with its proprietor, is round £145 ($180). Although they are often bought, these on the programme obtain them free of charge.
“It’s about constructing a bicycle ecosystem within the communities the place we function,” says Kelly. “We’ve one thing like 3,500 mechanics that we’ve skilled in our program nations, in addition to over 100 Buffalo bike retail outlets.”
The brand new two-chain system, Kelly says, is “easy sufficient” that any skilled mechanic can restore it. “It was actually kind of an engineering feat to determine,” he provides. “The suggestions so removed from our take a look at riders and the folks which are gaining access to this bike is that they love the additional gear.”

It’s no shock, too, {that a} second gear has been so welcome. The bike itself, constructed for sturdiness fairly than efficiency, weighs 23kg – greater than thrice the UCI minimal weight restrict. The body is constituted of metal, the edges from aluminium, and there’s a kickstand for straightforward loading and unloading.
Within the communities WBR serves, the brand new mannequin has been a “recreation changer”, Kelly emphasies. “It’s a tried and examined, strong workhorse that’s been designed to work in these environments.” Having surpassed 850,000 bikes distributed, the non-profit organisation is now excitedly honing in on the 1,000,000 milestone.
What this implies is that extra dad and mom, faculty college students and enterprise house owners like Achola can journey by way of their communities quicker. Because of the two-chain system, their journeys have now gotten simpler. “I actually would really like this bicycle to enhance the entire world,” Achola says. And it’s, one swift backpedal at a time.
