Absolutely worth it

I am completely in love with this bike. I am a college student and use this for my daily commute and pretty much everywhere I go within a few miles. I didn’t have a crazy budget because college and the 6ku urban track seemed like the best bang for buck so I went with it and I have no regrets. I’ve put a few hundred miles on the bike and everything still feels great. I upgraded the fork to the Crew racing carbon fiber fork from city grounds (it fits fine you just need to cut it to the right height) and I love the look and feel. Right out of the box the bike is super solid. The only thing I had to adjust were the height of the breaks but that’s no problem. All in all this is an extremely well put together bike that I find joy in riding every time I hop on.

Great Frigin Bike!

Bought one on a lark and had no idea of the company and the quality. When it arrived I was pleasantly surprised (for once in today’s marketplace) to get something that exceeded my expectations. Had the bike for a couple weeks now and ride everyday. Love this thing. A fantastic product for an amazing price. Keep it up 6KU. You guys are going to kill it!!!!

Weak hub (fixed)

They fixed hub didn’t least long, after a few rides with the fix side the small thread was completely stripped, then the fix cog spin and gets loose! Need to use better components! Besides that the bike is pretty good.

Great for the price

This bike has been amazing the first several months I’ve had it. It’s light, agile, and looks damn good. However, with time the components have worn quickly. I ride hard daily and take very good care of my bikes... bought this to be my new everyday commuter but wasn’t aware the wheel set came without sealed bearing hubs, hence the swap to the white State deep V’s in the photo. The bike rides well but not even half a year in to owning it the drivetrain is ready to be replaced as the bottom bracket sounds like it’s chewing marbles and I top out my speed quickly with 110bcd crank. Having a 144 or even 130 upgrade crankset option (as well as seal bearing hub wheelset) at purchase would be awesome for this bike (Aventon Push???) as I feel it has so much more potential. My riding experience changed drastically after changing out the pedals (I suggest doing this immediately) to some RaceFace Chester pedals. Overall the bike does seem like a great value for the money but definitely an entry level aluminum frame experience. A carbon fork option would also be great but then we’d actually be talking about the Aventon Cordoba... which is what I planned on upgrading to until I picked up a used State 6061 Black Label a few months ago, which is a size too small but definitely has shifted me towards trading both bikes for a new Black Label V2 in my size. None the less, I’ve enjoyed the Urban Track, and receive compliments on it regularly, but had hoped The enjoyment would have had more longevity. I did not anticipate having drivetrain issues so quickly although I do put this bike to the test regularly.

Urban Track Bike

I just received this bike and have only had the opportunity to ride it a few times. I would prefer to review it further down the line when I can ride it to class every day but I keep getting these emails. From the times I have ridden it the bike seems fantastic! Very fast, light, and easy to maneuver.
