TBH a bit short and too heavy for your size , I suggest you go to the shop and try sit on it and feel it first ... I'm at 173cm & 75kg my leg also tipping and can't full balance with two foot planted on the ground.

resting on traffic light is should be ur least concern, tipping toe with 1 feet should fine.
the real problem with heavy bike is when you want to reverse and handling it on low speed, which require to put ur feet down for stability.
