If you are too heavy for your wheels at 90 kg, then they're
poorly built.

It's likely your wheels have been laced and (under)
tensioned by machine. This seems to be the norm these days,
and resultant spoke breakages are all too common.

If you get the rear wheel rebuilt by a competent wheel-
builder, you're unlikely to have any further problems for
many 10's of thousands of kilometres - even if you were to
load the bike up with panniers as well.

No excuse for breaking spokes here, they should stand up to
a 90kg rider without a problem.

Correctly, the OCR2 wheel should go back to the shop for
correct tensioning. I have only had problems with spoke
failure on bought wheels which I have not tensioned and
stress relieved personally.

Greetings, No, the problem is the wheels themselves, I had
the same problem with a Shogun Metro hybrid. The wheels are
built to a basic standard and not designed to last. Your
best bet is to have the wheels rebuilt with stainless steel
spokes, will cost you a bit, but worth it. I have not
twanged a spoke in years. Your budget bottom bracket is also
likely to die a horrible death, and so will other items of
running gear such as the cluster. When you have finished,
you will have a half-decent bike. Regards, Ray.

As Ray mentions, worth getting (both) wheels rebuilt with quality (DT or other) spokes.

If its happening at the hub end, it may also be poor fit into the hole-face of the hub. I used to do one a month on a crappy STX-RC rear on my mtb commuter

The pulling off from the ights scenario is probably due to the 'torqueing windup' that occurs due to the power transfer from the drive-side of the hub to the non-drive side. the non-drive side 'catches' up and gets twisted placing huge forces on hub/spokes (this is all incremental, mind).
Is there any consistency of spoke location/side?

Love to see a 'wheel-building-machine'!
