Besides what I said about this not really being a market gap, I do have some honest suggestions if you are already committed to the project.


The folding mech needs a proof of concept. The problem is it's rigidity as this is a pursuit of a performance folding bike.


Ergonomics should be reevaluated in the design of the bars. As one of the major contact points the utility is more important than form language. The drops should be rounded and the top bar should be slimmed down.

That top tube is also far too wide. To be honest you need to start over. The mechanics won't work. Pretty things have to be functional.


Careful with the extrusion on that rear support arm. You need another proof of concept to make sure there is clearance for the crank arm/rider foot


The pedals are placed far too behind the seat as well. Geometry is everything, so research some other brands as their geometries are readily available. Doing a mock up will be very easy.

Also, you have no place to mount a rear derailleur. That will be quite an engineering problem.
