Quality components will be the key to success but manufacturing cost is issues.
also quality control is really important.
where do you plan to make this bike? If your factory is in China, it will be very challenging to make good products because of quality controls.

adjustable handlebar is good. I like 9 speed.
battery needs to be bigger 7.0amp is a little small. It should be at least 11amp.
location of battery is tricky.
people will ask for Rear rack.
also focus on small details such as hubs and headset with sealed bearings.
for Brake, I prefer hydraulic brakes but I want better quality hydraulic brakes instead of unbranded brake company.
my bike has it but not happy with it so I put magura MT4. It makes so much better.

honestly price of $2100 might be challenging since it’s new company.
