6KU Aluminum Fixed Gear Single-Speed Fixie Urban Track Bike

Excelente relación calidad/precio, el cuadro se ve y se siente muy sólido, los frenos no tan buenos, el sillín ya se lo cambie así como los pedales, pero insisto, por ese precio no se puede pedir más.Update: la bici continúa funcionando perfectamente, pensaba cambiarle las bielas y el BB pero han funcionado muy bien así que los dejé, prácticamente el único mantenimiento que le doy es ponerle aceitito a la cadena, a también le cambié los frenos.

Es una excelente bicicleta. Es muy ligera y su estructura parece muy firme. Lo único malo son los pedales de baja calidad, pero el resto de la bicicleta es excelente.Contras: La capa de pintura es muy fina, cualquier golpe en la pared y se pelará del aluminio.

Ya llevo unos 2 meses con la bicicleta, es muy estable, ligera y sobre todo luce muy bien, se me ha pinchado la llanta trasera aproximadamente 7 veces, pero eso es por las condiciones de mi ciudad.La calidad de los frenos y el sillín son regulares. Se debe tener cuidado con la pintura, no es tan fácil pero como es negro matte, se nota muy rápido si se raspa con algo.

Came with Bullhorns. Nice frame. Looks great out of the box, however, the front fork drops were a little too tight for the wheels to fit in. Had to file it down a little. Once set-up, the bike is good for what they're asking for. It will need a better drivetrain down the line.

Estoy muy contento con esta bicicleta, calidad, peso y funcion mejor de lo esperado.

Good that is good.

Me gusta su peso, te desplazas sin complicaciones, la armé yo solo, ajuste los frenos con videos de Youtube, Fantástico.

Muy ligera, buenos materiales, y fácil de armar.

Great bike, lightweight, great price !!

Delivery was delayed a week without warning. The product was left at my door with the box opened. Missing the hex tool which was supposed to be included. Broken tire valve plug. Scratched handle bar.Bike itself is beautiful and rides very well. Instructions somewhat easy to follow for assembly.

I was surprised to find zero reviews on this bike when I was shopping around, so I assume it's relatively new to Amazon. I checked some opinions around the net for this brand and found them favorable enough, when considering the price point, so I took the risk.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.Pros:- 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 pressureNeutral:- 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)Cons:- Pedals are fairly cheap and large.- Wheel reflectors are unavoidably wobbly- Front reflector mount literally has no place to be mountedOverall 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. Takara Kabuto Single Speed Road Bike

You get what you pay for, and then a little more....problem is your not paying very much. Overall this is a solid bike for the price, but don't expect any frills or reliable parts. I ride this bike every day as my primary mode of transit, probably around 50 miles every week.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.

Like other people said you simply can't beat what you get for the price, I've had the bike one week now I'm loving it, The only slight drawback I have is the bullhorn bars are a bit too narrow for me, looks like this will be my first upgrade, also I've noticed the rear tire has the slightest/smallest of leaks but that is to be expected with presta valves especially in this price range but nothing drastic I just pump it up a bit before some rides.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 :)*Update* 1/29/17The 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.Update: so I've replaced the BB and made some external cosmetic mods, and I'm loving the bike. Added new up to date pics.

This bike is almost perfect. It was very easy to assemble. The fit was great as well. I am 5'11" and 160 lbs with a longer torso and rather shorter legs, and 55cm is a perfect fit. Every component seems to be pretty decent and durable except the rear wheel. It was a bit lob-sided and also the freewheel component is either missing a ball bearing or under lubricated, which prevents the wheel from rotating freely. Because of that, it requires more pedaling and also climbing hills a lot harder than expected.Other than the back wheel, I like everything else about it. Affordable and well-built.*** UPDATE ***It turns out the sound was caused by the tight chain tension. Once I loosen it up by moving the backwheel a tad bit closer to the crankset, the sound went away.

First I don't ride every day, when I do once a week I ride about 30 miles on it. I have had it for about a month now so I have a bit over 100 miles on it. With that said this is what I think about this bike.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.
