It was worth it.
This bike feels high quality, is much lighter than my previous beater/commuter from a similar price range (stolen): Takara Kabuto Single Speed Road Bike, and I'm really quite happy with it. Because of the ridiculously high number of bike thefts in San Francisco, I don't look for expensive bikes so value for money is important. Packaging was sufficiently strong to keep everything in good condition en route to me and there was an included manual that covers basic bike construction and maintenance. 6KU also included some stickers in the box and some velcro straps that I've yet to determine a use for.
- Bolts and chain were appropriately lubricated
- Welds look very high quality
- Handlebar grip tape has some squish to it
- Visual appearance is high quality, the matte black is uniform and great looking
- Construction was straightforward and there are small guide markings in a few places to help with alignment and setup (for example: seat forward/back and bullhorn handlebar angle)
- Weighs less than expected
- Brakes were well calibrated out of the box and apply equal and solid pressure
- Seat is moderately comfortable if a bit high friction and slightly long (note contact with bag in pictures), but may be on my list to replace over time
- Rear tire was installed backwards. The chain was set on the non-fixed side but the tire rubber ride direction was set for the reverse so I had to take the rear tire off and deflate it and flip the tire on the wheel
- No bottle cage mount points
- Brake pads are fairly cheap and I will likely replace them (this is almost a non-issue as brake pads are so cheap)
- Pedals are fairly cheap and large.
- Wheel reflectors are unavoidably wobbly
- Front reflector mount literally has no place to be mounted
Overall I'm going with 5 stars instead of 4 as I don't think the above cons are negative enough to lower the rating at this price point. For what I paid, this is a solid bike. If half stars were an option it'd be a 4.5.
I was noticing slight creeks from the stem/handlebar but that was due to me not tightening enough during my tune in phase on build.
I'll update this review after some more riding but so far so good.
KUDOS to 6KU on the bag of stickers I got with the bike too :)
The bottom bracket is creaking now, looks like I'll need to replace it, but expected this based on another buyer saying the same thing, but i can't wait to put in a better one anyways, these bikes are all about customization and upgrading.
My 5 month review (part by part):
Frame & Fork - 4.5/5: Very happy, minor gripes are a 'hard shell' enamel style paint that chips easily and the lack of mounting points for any sort of water-bottle holder etc.
Wheels 5/5: No complaints here, just know the black paint/coating will be quickly worn off the rim by the break-pads.
Flipflop Hub 2/5: This had a little 'grind' and uneven resistance right out of the box. After months of riding it has only gotten worse. Unimpressed, soon to be replaced.
Tubes 4/5: Had some ruptures fairly quickly, though I do ride it hard over rough city streets.
Breaks 4/5: They work well, and I am glad to have front and back. However the front breaks came a little bent meaning the pads are impossible to correctly align and wear faster. Also the pads it comes with are fairly stiff but get the job done.
Crank and Sprocket 5/5: I want to rate them lower as they seem very cheap. That being said I have had no problems so....
Pedals 4/5: They are nice and large!! Though the plastic does give a little flex under full weight when peddling. Could be more sturdy. I upgraded to metal fairly quickly.
Handlebars and Neck 5/5: I was expecting to buy a set of bullhorns, but these really do feel great. The short length and angle of the neck make them feel very aggressive.
Seat 2/5: I mean technically there is nothing wrong with this. But I am used to riding BMX plastic seats, and even those were somehow more comfortable. It really put a lot of uncomfortable pressure on me when seated in almost any position. I replaced this within a week.
TLDR: The big parts they get right, everything else is where they save money and bring the cost down. Still a good deal, expect to replace a bunch of parts in the near future.
The bike is solid, nothing sound on it even though I did not fine tune it just put it together, well pack and easy to put together. It's fast and I feel the gear ratio is perfect,I live in Florida everything is flat here so it's perfect, even when I'm climbing it feels nice and light. Brakes are good too, everything feels of good quality till you get to the pedals. In fact the treat in one of them was almost bad I had a hard time to install it. Saddle I ok as well, after 20-25 miles it hurst without bicycle shorts with bike shorts it's not so bad.
In general I think the bike is got all it needs to exceed expectations of anyone that understand how much this bike cost.

The one thing I do not like is that it does not have a stand so there is no way to keep the bike upright,
