I wonder what the Burn rate for the company is...

It does not take long to run through a lot of money running a company when it is not producing anything.

Big Money upfront for starting a business can often cause a higher burn rate.

Major changes in direction from Welded to Glued back to Welded scare me also.

It would not be all that expensive to ship wheels from Asia. You could easily get 1000 to 1500 wheels in a 40 foot container---my guess---and that is about $4k to $10k for shipping. I don't know about Duty however.

You can get right at 300 Mountain bicycles in a 40 foot container---that is my baseline for size.
