To comment on the bicycle itself, the 2 chain thing is cool. I don’t exactly know how it works, but I have already seen retro-direct setups (1 chain + 2 freewheels, with-or-without a jockey wheel) and it is something that has interested me. The big difference here is that with retro-direct, you keep pedalling backwards for the other gear.

I imagine retro-direct could be done with 2 chains for the redundancy, perhaps even with different types of drives for each (like some cheap geared belt for the low gear, normal chain for high gear). Though this would be more suitable if swapping out gear combo was not too difficult, to adjust to rider fitness.

EDIT: I should say with chain vs belt I mean whichever gear you expect to require the most force which may in fact depend on cargo weight+hills. Though the chain being the smaller one might just be smart to reduce wear (esp. w/fully enclosed chain case, exposed belt).

I have no doubt the S2 is a good bike for its role, but there are a lot more nuance to WBR’s projects in Africa…

I’m not a fan of this article, mostly because Evan Christenson contemplates the darker side of charities working in underdeveloped countries without actually exploring them beyond criticizing WBR. It’s, likely unintentional, FUD propaganda.

It should not be a shock to find out that charities have overhead and many of them have unfortunate side effects. For example, Evan brings up Doctors Without Borders as a charity with lower overhead and a leader less compensated. That’s true, but did you also know they sell your personal information when you donate to them? That’s part of how they lower their costs. Also they provide doctor services for free. What does that do to the doctors who are there trying to make a meager living? DWB is undermining what little medical infrastructure the country has.

Is that a bad thing? Is it a good thing? That depends on you, the donor’s, perspective. Selling my data to provide more doctor is fine with me. Same with undermining the countries’ medical market because it’s a temporary thing and usually in a crisis where not providing help is definitively worse.

I’ll continue donating to WBR because their expense ratio is acceptable, even good, for physical good imports given the shipping overhead (aka bribes) in Africa. Admim is ~15% and fundraising is ~23%. Everything else goes into the bicycle and into families with kids who cannot afford one. That’s a lower margin than buying just about any good from your local shops, and it’s lower than many other charities working in Africa!
