This bike is aimed at the walmart and best buy crowd.
I know I sound like I'm repeating myself, but from the beginning I've targeted the concept of the Electric Bicycle Road Racer as a WalMart product. If you go to WalMart and check out their existing electric pocket bikes you would see that they already try to sell into a teenage marketplace.
The idea is to simply make a "faux road racer" electric bicycle that just so happens to actually work well. Sort of sneak the product in.
It's not like we're selling Tobacco here... kids are going to ride around on the streets and do silly things no matter what products are available, but the idea would be to build something that was designed with actual understanding of what a good "road racer" might function like.
Anyway... sounds like you have your mind set on the board track racer idea... I really don't think that a 16 year old will understand the appeal of "retro" styling. Older ebikers (40-60 year olds) like the idea of "retro" because it helps comfort them in their old age identification process. They think "ah, the old look was so cool... sort of like how my gray hairs are cool."
I might be wrong but if I were to make an association I'd say:
Board Track Racer Demographics - 40 to 60 year olds
Road Racer Demographics - 14 to 30 years olds
...the people from 30 to 40 are so busy with their main lives that they usually don't have too much time for hobbies.
WalMart bikes should appeal to children.
