Market Research for Hoverboard Niche

Hello, I'm needing market research done for the hoverboard niche in the Australian market. If the niche proves to be viable I'm looking to build an online ecommerce store with dropshipping. These are also known as segway's, mini-segway's and self-balancing scooters. Note: They may be known as other things to but this is just after my limited research in Google. Essentially, I need you to do 4 things: 1) Market research (including competitor analysis) on the entire niche so I know the in's and out's of the niche. Jargon, lingo and everything! 2) Research this site: [login to view URL] and explain to me why it is doing so well and what we can learn from it. It's making $3k per day and a 12 year old is running it. I know this for a fact because there was a news story recently (which I missed) on her doing so. I note the keyword 'jyro' only receives limited amounts of searches per month so I need a better understanding here. 3) Whether it's viable for me to invest in an ecommerce store 4) If viable, I need you to assess whether [login to view URL] is worth investing in. It is a dropshipping ecommerce site that is set up to go. Please note I have no opinion on whether this niche is viable or not. I will let you do your research and make a decision. You should also note these products have already been banned in NSW (a state here): [login to view URL] and new york. NEED SOMEONE TO DO THIS QUICKLY BUT ACCURATELY: If I'm going to invest in this niche then I need to act quickly before Christmas. I will hire straight away.
