Is this the same as the bikerdoc bars?

I like the bikerdoc bar but I feel its a bit too expernsive for a unbranded carbon bars.
I cannot speak for the Balugoe or EC90 bars, but the quality of my specific copy of the Bikedoc bars seriously exceeded my expectations. They are nice and clean and easily as good as the Enve bars they replaced. I think the quality is worth the cost.
That said, there is a considerable price difference between the EC90 and Bikedoc design. The EC90 bars are about the same price at Aliexpress wholesale price as I was offered as the per unit cost AFTER the cost of the mold. This makes me believe there are other differences (e.g., material). However, I would choose based on your desired shape, since the bar shapes are so different. The 7mm lower lever position is not minor, nor is the similar amount of additional wrist clearance when sprinting or climbing in the drops.
I had the Enve Aero bars on the bike prior, and I liked them a lot. I did find out of the saddle in the drops; the Enve bars had just enough clearance. The Bikedoc bars have a little more than the Enve bars did and the ec90 bars will be less than the Enve bars, if the drawings are correct. The Bikedoc bars also work better for me in the aero hoods position than those did because of the lack of rise on the ramps where the drops meet the tops. I do turn my levers in, though less than before, as mine are set up using the current UCI rules as a guide. I had previously found that the position was most comfortable with the Enve bars was with the levers turned in enough so that my wrists naturally sat inside of the rise on the ramps. Hope this is helpful.
