Hi guys, I was hoping you could help with my spoke-cracking problem.

I bought an Oxydrive 26" kit last year (250W). They didn´t have 26" in stock, so the kit was delivered with an aftermarket rim. After a week or so the spokes startet to crack. They sent a new set of thicker spokes and I built the wheel with the same rim. After a week or so, when on a trip it startet cracking again. I stopped at a bike-shop and they changed the rim and spokes and used a stronger spoke pattern, but again after a few days it startet cracking.
It is a cargo bike (larryvsharry bullitt), however, I have another Bullitt with the same Oxydrive kit on an original rim and have never had a problem with that.
I read that because of the motor e-bike rims should have a bit of an angle so not to strain the spokes to much. That is why im trying to find a strong e-bike rim and DT Swiss spokes and to build the wheel one more time.
Thanks for youre help

DT Swiss make an e-bike specific rim. Or you can go for a wider BMX or downhill rim such as the DeeVee or Alienation.

Thanks guys. Haven´t seen if DT provides rims drilled at the right angle for the CST motor but I´ll write the company and see if that is the case. I also found "Ryde Andra 40" and according to their homepage they do provide custom drilling for e-bikes.

DT Swiss is actually made by giant they share the same factory half it they do bikes and the other half is dt swiss rims and hubs

You need thinner spokes, not thicker. It should be OK with any cheap Chinese rim and 14g spokes.
