Spokes keep op breaking

[Roadkill]

I have no idea what the front fender is in this pic but I am certainly making on here!! Perhaps for headlamp. Low and high beams.

The 5 extras look pretty tough. Any idea what the blue seats on the back are called?

The bicycle taxis the extra 5 bolts through the sprocket should help I think.

I don't actually know what the seats are called, all I know is that they are cheap to make, 4 euros. Some Dutch guys import them from Kisumu, Kenya and sell them online (www.bodaboda.nl/enwww.bodaboda.nl/en)

I finally decided to weld all the existing holes in the sprocket and start with 10 brand new holes. Had to drill all 30 holes (sprocket and back plates) by hand though...very tiring.

All seems to fit well though and already took it for a spin of about 25 km.

Even stumbled across an old MG A today near the school I volunteer at. If any of you are interested in the work my wife and I do visit the website of the school at: www.facebook.com/WaithakaTTC [ Feel free to like the school page.... ;-) ]

Had a problem a few years ago with spokes breaking. Once I realized they keep breaking in the same place (Spoke head) I found the problem. Was nothing to do with the wheel or spokes it was the hub causing the spoke heads to break off.

Once I replaced the hub with a new one, had no more problems.

I had exactly the same problem with several rear wheels, both human-powered and motorised. I learned to open up the hub spoke holes and chamfer the edges well. This fixed the problem every time, even with original-size spokes.
