6KU Fixed Gear Single Speed Urban Fixie Road Bike

I've put a couple hundred miles on it now and I absolutely love this bike.It's like riding on an ice skate, it's so light and effortless to move and coasts forever. I find myself reaching for it instead of MUCH more expensive road bikes or even my ebike for many rides. I love the classic round tube look and black/white color scheme. The 6KU logo and "Fixie" badging are stickers that can easily be removed if you want a fully anonymous bike which is a big plus to me.I've ridden it both freewheeling and fixed and it's solid and stable either way. The ratio has been great for me so far and the XL fits me great at 6'3". The tires it comes with are great and have been flat free so far on dirty Los Angeles streets and bikeways. The brakes grab hard once properly adjusted.The only issue I've had is the saddle it came with was a bit too narrow for me, but saddles are such a personal thing I can't really hold that against the bike.Also, there are no eyelets or braze ons for a rear rack, but I knew this before I bought it so can't hold it against it either. Maybe it's a good thing because it keeps me from putting a bunch of junk on.Overall this is a terrific bike and I'm recommending it to all my friends who want something cheap and cheerful.

It’s a cheap Chinese bike with stickers on it probably sold by a number of companies, I have a suspicion it may be the Same bike as the slightly more expensive avasta fixie. I Purchased this bike because my car blew up and I needed a way to work. I am not rich, so I searched bicycles for hours and found this inexpensive one. When I first received, the front brake would rub and I couldn’t get it to stop so I ended up just throwing it away, I just use the back break which is not the best.(Doesn’t stop fast drags a bit)My plan for this bike was to slowly upgrade it into a decent bike and use it to commute to work.My commute is about 25 miles round-trip. this bike made it to my job and back twice and I’ve been riding around town on it to get food and things as well. Still on the stock inner-tubes.I’ve replaced the pedals, added a mirror and a new seat.The stock seat Is absolutely terrible and left my ass and taint area very sore after one day, I recommend immediately replacing it.The grips are cheap but ok.Both breaks are not great.The frame is very light, I carry it upstairs everyday.I bought new pedals because when I was leaning on them I would get some flexture.After replacing I realized It was the Crank flexing a little when leaned on, so I’ll probably eventually replace it with a metal one because it seems to be made of plastic. The stock pedals are Chinese and thick plastic but seem decent enough to last a long while.The back wheel kept coming out of alignment, but I searched a YouTube video, and it was easy to adjust it.The chain hasn’t broke on me yet! 🤞I’ll be putting new wheels on it and slowly upgrading pretty much everything.Bottom line: It’s a great bike for the price, but don’t expect perfection.I’m VERY impressed that the innertubes have held up this long.I’m worried about the chain breaking on me just because its gotta be cheap but I’ve yet to have any issues!I’ve had the bike maybe two or three weeks.If you bought this bike and just changed the innertubes im confident it would get you there.

Shipping did not take long. The axles did bust through the sides of the box but nothing was damaged. Otherwise packed very well.Was very straight forward and easy to assemble. The safety stickers on it for the pedals and which way to put the fork also removed easily and did not leave a residue which was appreciated. All the other bikes I owned leave a goo behind. The wheels spun straight and tru which I was surprised by since any other bike I bought under $700 the wheels needed truing out of the box.The stock handlebars were very cheap and narrow with cheap weird grips. The bars taper to 22.2mm which is narrow than common replacement grips. I intended to replace these anyways which I did with with 440mm drop bars and a stem with a 31.8mm clamp. The other issue with the stock bar diameter is the stock brake lever clamps are too narrow for more common handlebar replacements. I only wanted to keep the front brake as an emergency brake so I just took the brakes off for now and ordered a new front brake lever/caliper from State Bicycle Co.The tires are cheap Kenda commuter tires. They are probably fairly durable but I immediately replaced those as well with some fairly light faster rolling Specialized Roubaix Pro 25/28s I got on clearance.The only other issue which isn't a big deal is the seat post is narrower than the common standard of 27.2. The stock post is pretty light and should last so it's all good for now.This bike is on the heavy side with most of the weight in the frames, the individual parts are fairly light aluminum, only way to make this lightly would be to replace the fork which wouldn't be worth it. Crankset/ bottom bracket replacement can also probably shave some weight too but I'm going to wait to see how the stock one holds up.Need to see how it performs long term, overall based on one ride and assembly is solid bike that is aesthetically pleasing that will make a great town and rail trail bike.

It's a bike—light, fast, and simple.

Ligera, agil y de buena calidad

Such a great bike got stolen the 3rd day. 🥲🥲🥲🥲

Me gusto: fácil de armar, se ve increíble, es de buena calidadNo me gusto: talvez que la d acero en tamaño XL esta un poco más chica en comparación de la tamaño XL de aluminioMuy recomendable, le cambie el manubrio a uno bullhorn y definitivamente no le instale los frenos que trae. Es una verdadera fixie
