On my past 2 rides, I have broken one spoke on my rear wheel taking off from a set of lights. On the first breakage, I was 200metres from my car, so I kept riding... LBS fixed the wheel and my next ride same thing happened from the lights. The wheel is back in for repair and looks like getting a rebuild. My bike is a Giant OCR2 and is less than 6 mths old with just under 1900kms on it... I weigh 90kgs, but I always check tyre pressures before I go out... Am I too heavy for the wheels??

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.

Any help is appreciated,

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'! Have images of 'Go-Gadget' contraption with telescopic arms flying all over the place 😄
