James, from what I can see you need a bit more business-related experience.
How big of a market is there for a portable exercise bike if a regular bike combines the functionalities of biking and being mobile.
The hiking tripod is a great product in terms of design, but how will you get it to stay in the minds of potential customers and make them interested enough to learn about retail channels etc. as well as finding those customers who simultaneously have the need for a hiking pole and camera tripod.
New innovations like that have to be extremely clever and sort of hit a spark in people. You have to decide if you want to go for developing a product like that and do a startup, or if you want to join the local industry. In my experience it is best to get a position somewhere and just develop from there while always working on your own ideas as well. Find out what only you can do very well, and create a better story around yourself. In the meantime keep working on your design and visualization skills.
