Bikes EURXC550 21 Speed Road Bike 700C Wheels Road Bicycle Dual Disc Brake Bicycles

I'm about a week and a half in with this bike and have hit almost 60 miles already. Some notes so far.First, assembly.Assembly was fairly easy with the installation of the handlebars, the seat, the pedals, and the front wheel. The front wheel proved to be a challenge since I wanted to make sure the handlebars and wheel lined up correctly. After the front wheel was installed, it was a little tight when you'd spin and get a few rotations before stopping. This was fixed by loosening the calipher slightly behind the brake pad with an allen key. Make sure your brake lever is even when you are doing this. If you loosen it too much, your lever will go all the way to the handlebar.Secondly, riding.I didn't take the bike for a cruise right away but rode around my complex's parking lot testing gear shifters, brakes, pedaling, pushing down on the handlebars to make sure they weren't loose, pushing into the seat, etc. I gear shifted too fast and caused the chain to get loose at the rear sprocket. It was able to be slipped back on with no issues. The chain has only come off one more time since then in the middle of a 19 mile ride. This was from pedaling too hard while shifting. Gear shifting is not as smooth. I will try a higher end chain lubricant to see if that smooths out gear shifting. The disc brakes are fantastic especially for hilly terrains where I live.Overall, I am pleased with the bike. I took the stickers off the wheels because it looked a little silly (Sorry Kingtutbike!) I wish it came with a second set of water bottle mounting bolts on the upright frame. A few minor tweaks with the chain and gear shifting can get the bike up to speed. I took it on a 19 mile cruise this past weekend and other than the chain slipping halfway through, the bike delivered a great a ride. It's smooth, fast, looks, and feels great. The steel frame is not heavy for me at all. I took a star off due to the chain issues. If you are a beginner cyclist like myself and on a budget, this is a great bike. I upgraded the stock pedals to Shimano M520 Clipless pedals.Edit: 7/18/18 update. The front tire presta valve started leaking air. I have the bike with the aero spoke wheels. The tube is a very specialized 700cc by 28 80mm presta valve. The 42mm and 60mm valve are too short for the tire rim. It's been problamatic trying to find the correct tube size. The local bike shops do not carry that specific tube on hand so it had to be special ordered It doesn't say on the product description but make sure you buy the right size tube with a 80mm presta valve! It will save you the headache.The rear derailleur was also not shifting all the way correctly and would shift on rides so I had the bike shop tune it along with tightening the headset. The left brake lever started slipping down the handlebar and I was having a hard time reaching the allan bolt behind the brake lever to turn with the allan key to tighten it. I sent a message to Kingtutbike and they responded very quickly and provided instructions with photos on how to tighten it. I was able to tighten it back up. Great customer service.I am a 5'7" woman and bought the 54cm frame. It fits perfectly fine for anyone else in the same height range.

I work as a bicycle mechanic and recently had the misfortune of servicing one of these bicycles. Let me be clear: this is one of the worst bicycles I have ever worked on.The bike weighs in at about 33.5lbs, which is a heavier than some mountain bikes. The welds are spotty, inconsistent, and generally terrible looking. Parts were installed improperly (headset was assembled incorrectly and without grease), and the bike was unrideable in brand new condition. It took the bike's owner $100 at a bike shop to get this abomination to a point where it was even rideable, and it's still significantly worse than any other road bike I've put my hands on.If you've got a $300-400 bike budget, you're much better off going with an entry level bike shop bike or scouring Craigslist for something actually roadworthy.

Okay, first of all! I've looked so much to find any info about these bikes. YouTube, Google, name it. And, nothing! With that being said I was a sceptical. I took a chance and ordered one. Shortly after, bike arrived to my place. Box looked pretty sturdy and safe. I started to unbox, thinking OMG this is going to be a nightmare. However, bike was very well protected lots of foam and tape around all of the parts. After good 20 min of using my tools and my knowledge of assembling bikes. Eurobike was fully completed. With some minor tweaks on the breaks and steam/ stear adjustment. I decided to take it out for a spin in my neighborhood. Few miles later, I had a huge grin on my face... This bike was amazing! Whoa I did not expected this exitment. I mean for the price and free shipping common you can't get a better bike out there. Additionaly, just for my preference I will replace the brakes, crank, and steam for something more durable. Hands down, I am very satisfied with my purchase. I mean few upgrades you will have a solid bike that will turn heads for sure.

I went through several reviews before making this purchase, and I'm very pleased. The bike looks and handles amazingly. However, I am new to riding so I don't have much to compare it to. It is heavier than more expensive bikes and the mag wheels add additional weight also. However, I'm using this bike to train and get in better shape so I'm ok with the weight to increase muscle strength w/o having to spend a ton of money.I'd only recommend this bike to beginners. Primarily because the chain wheel is 42T. That is small as standard road bikes come with 52T or 53T. The larger chain wheel allows you to produce more power which means the bike can go faster. However that also means it is harder to pedal which is why I prefer the smaller chain wheel as a newbie to cycling. I also stay in a hilly area so the smaller chain wheel is much better for my needs.The seat is pretty uncomfortable, but replacements are pretty cheap. I added a gel cover to mine until I can find a better seat. Other than that, I don't have any other complaints. Well, I didn't like all the stickers as the graphics were a bit overwhelming so I took some of the stickers off the wheels.For the price, this is a great buy!

A few nicks and scratches. Needs a bigger front crank, as you over pedal going down hills. But it looks great for the price.

Avons acheté ce vélo pour un ado. Il l’a monté seul, l’ajustement des freins un peu ardu pour un jeune. Il est plus lourd que son vélo d’origine mais roule mieux et plus vite. dans l’ensemble, il est très satisfait

They have excellent support. They were able to solve my issue immediately
