The first bike I ordered had a problem with the forks. On one side, the opening wasn't big enough to attach the front tire, so I had to return it and exchange it for another. Unfortunately, the second bike suffered from the same problems that many other reviewers have highlighted: the bolts are screwed in so tight and are so soft that one risks stripping them if they try to unscrew them. So I was unable to properly attach the fenders, which meant that they bounced off the tires. Given that I was intending to attach a weerider co-pilot to the bike in order to drive my daughter around made the fender issue a problem. The threads on the pedals are also very easy to strip. Lastly, the mount for the light was not attached as indicated on the company's website, so I was not able to attach the light to the frame. Overall, the quality is not very good. I returned it, decided to take a trip to one of my local bicycle shops and spend $50 more on a much higher quality bicycle.

2.0 out of 5 stars Not even a Critical Cycle
Reviewed in the United States on August 21, 2015
First off, I purchased this bike because in the last two years I have had 3 very nice bikes stolen (under crazy circumstances) A Salsa La Cruz, a Raleigh, and most recently a vintage 3 speed I was restoring. I couldn't afford to buy anything like what I have had in the past, due to hard economic times, I am just one of those people who needs to have a bike to ride so I had to figure something out.

I was very optimistic going into this purchase.

HOWEVER, when my RETROSPEC??? box arrived I was a little surprised, however I thought maybe they were partner companies (w/ Critical) and they were just "recycling" boxes. While they may indeed be sister companies/ possibly the same company, I was not expecting the bike to have Retrospec stickers on it as well. In addition, the stickers were not even applied with what seemed like any effort, the one on the chain guard was crooked and one of them on the rim was already dirty and peeling off.

The next thing I noticed was that the tires were cream colored and not the grey they appeared to be online. This is isn't a huge deal, the tires are Kendas and I can deal with that.

The biggest disappointment with this bike was that the rims are extremely cheap. I totally expected some things to be of cheap quality (which they are) such as the headlight and bell. However, I'm pretty sure even Wal-Mart has better rims on their bikes. They refer to them online as an alloy, which is a really flexible and vague term that i don't really trust at this point.

I am a certified bike mechanic and have owned multiple bikes of various qualities. I have followed Critical Cycles since their company first popped up on the internet with their fixie model. I read about the company and followed them on social media, believing the message they were communicating.

Needless to say, I was excited to get this bike and the company even gave me a discount with the police report I provided when my bike was stolen recently (the reason for two stars not one).

I can empathize with cutting corners on certain components in order to provide a customer with an affordable alternative to many of the expensive bikes on the market...HOWEVER, rims are pretty important in my opinion. And in this case, I almost don't trust the bike to do anything but ride slowly on flat ground.

The breaks are insanely cheap as well, another thing that I wouldn't compromise on to that extreme. I KNOW Wal-Mart bikes offer better breaks than these. They are really really poor quality.

Overall, it wouldn't be worth the postage to send this bike back. I imagine this bike will last me, best case scenario, six months.

I sure won't be showing this bike off to any of my friends, I am 100% embarrassed to have made this purchase, as someone who has a lot of knowledge and experience with bikes... this is the worst judgement call I could've made.

More than anything I am saddened by the illusion this company creates through online marketing and social media. This company is not a "grass roots" little company just trying to provide people with the "joy" of biking. This company is a huge con and I am seriously bummed out by my experience.

***Note: I purchased this bike directly from the Critical Cycles website, but thought it was important to share here as well

3.0 out of 5 stars [Revised] Relatively Good Bike
Reviewed in the United States on April 18, 2013
Verified Purchase
I recently purchased the 55 cm version of this bicycle in black and it's really great! The delivery was prompt and the assembly was relatively straightforward (It was a bit of a trial and error experience...). Its front lamp, gear rack and fenders really make it an ideal bicycle for riding in a university setting that frequently features snow and rain. That being said, it kind of skimps on performance.

I currently live in Chicago and within a month of having it, it really had some wear. The tires would go flat pretty easily and I had to get the rear tube replaced. The back rack doesn't stand up to bumps very well and after riding around with this horrendous clanking noise, I finally found out it had been flopping around on the back of the bike. The front light also constantly droops down so I just ended up removing it and the bell. These problems are likely due to my subpar construction of the bike, but that could have been avoided with some build instructions. The build of the bike itself is also somewhat to blame.

However, it's a pretty good bike that looks great. Happy riding!
