Hamster Wheel

[sam20e]

Hi guys

so we recently bought a female robo hamster from a pet store. The thing is without realizing we bought a small cage which already had a small sized wheel (i think it's 4 inch) but my hamster keep on flipping up side down because she was running very fast. Then i read online and most of them suggested that Robo requires at least 6 inch wheel. So I bought a 6 in standing wheel. Now it's not that bad but still she is flipping out, tripping over, going one full circle upside down all.. is it normal? last time i had a winter white and never had this issue. I'm bit worried if she is going to hurt herself.
