> That being said I wish someone would make an enclosed bicycle/motorcycle that costs less than $2000. Something like that which can go 30mph and had space for 2 days of groceries would be enough for me to eliminate my car all together.

You can already get exactly that kind of vehicle for relatively cheap, though not as cheap as you're proposing... it's called an electric golf cart or, for the upscale versions, an "electrified low-speed vehicle". They start at about $5,000 from US manufacturers, but you can cut that down to around $3,500-$4,000 (including shipping) if you're willing to order off Aliexpress.
