One design flaw which I’m NOT comfortable about

When I first assembled the bike, there were multiple problems which I encountered. The head tube needed greasing which I had to disassemble more upon arrival because there were 0 grease in it, therefore it was already creaking. I had to watch YouTube for that. This was still ok despite the fact that the instruction video didn’t show anything about this and made it seemingly very easy to assemble. Next one is the problem which I didn’t like and this was something which I wanted a pro to see if this could be fixed. When I first built it, (imagine yourself looking at the bicycle from the front directly looking at its face) the rounded area where the front bike’s tire goes into its dual pivot brake is EXTREMELY CLOSE to the top of the rubber tire. It’s literally 1mm away from touching the top of the front tire with the dual pivot brake. I’m an amateur but any amateur can think “is the front brake supposed to be so close to the top of the rubber tire?” I couldn’t adjust it anymore to make it go at least even 1cm away from the top of the tire. I took it the bicycle shop and they said it was a design flaw. No sh*t. It’s only 1mm away and I couldn’t adjust it either! If this touches my tire, it’s either going to slow down my bike tremendously or come to a complete halt. In the worst case scenario, I could even flip forward towards the ground if the front tire touched the brake too much. I just couldn’t believe that they said it was a design flaw and I was hoping they could do something about it but they said they can’t. Design flaw with a tire that they sent? You’ve got to be kidding me. Also the wheels weren’t true as well. Not to mention, it was pretty bad and wobbly. I spent 90 dollars extra in total for trueing both wheels and brake alignment (which I was hoping they could raise the front dual pivot brake by 1 cm but they could only raise it by 1mm which was my initial result so I just wasted money on having a pro adjust my brakes). See the attached picture. This is AFTER I had it all done at the bicycle shop. All in all, it was a long tedious work including research time and extra money to make my bike rideable. FAAAAAR exceeding what it was shown on the set-up instructional video. Be prepared. The frame itself is super light as it is an aluminum but everything else was not a good experience.

Great road bike

The bike arrived on time and with all the parts. It didn't take long to assemble the bike. I love the color and it is comfortable to ride .I was surprised there is no kickstand, but I'd recommend a better seat and pedals if you are going to be using the bike for a long time or you are a taller person.

Baller bike

Had this bike now for 3 years. Absolutely sweet bike. It’s like having an urban mountain bike. Not as fast as my road bike obviously but in many ways more enjoyable. Basic in so many ways but this is what makes it so enjoyable. I can commute but it’s great for jumping curbs and navigating the urban landscape. Not once have I had any issues with it.
