While my opinion on what’s great, good, fair or junk isn’t exactly credible, I can still use my voice as to what is good for me personally. After a new saddle and some (very slight) thicker tires, this baby rides like a fantasy. And for a little under 500$ ( not counting shipping & tax) it’s well worth it. Future buyers will most definitely want to opt for the bigger tires and more comfortable saddle. I paid a little extra for drop bars and upgraded pedals. Bottom line, this machine kills fascists.

Solid value

I ordered the bike for my daughter who wanted a simple, low maintenance, single speed bike. The stock tires measured 23 mm on the calipers, even though they say 28 mm on the side wall. (stock tires are not the greatest.). I ordered a set of Ritchey Alpine JB’s in 30mm with a tan sidewall. They fit great (with a little room to spare) and look awesome! The other short coming on the bike if I’m being honest is the seat which is hard and cheap, so I ordered a comfort saddle off Amazon those two improvements have made the bike near perfect for her. She loves it!! it’s a solid performer in a great value !

Picked up used and is a home run!

I picked up a 2019 model Core line for really really cheap. Sometimes without even trying, I am able to smash my PRs that I made with very expensive carbon fibre bikes like my Roubaix and Domane. I did fit my Core with some drops. I really enjoy riding this bike.

WAY nicer than I expected!

My new Earthstone Core-Line looks and feels much better than I expected! Feels super solid and looks sleek & sultry, and I love the red anodized hubs! It received some minor boo-boos during shipping, but the friendly local mechanic fixed the spoke, rim tape and added some lube where needed. Can't wait for the sun to rise so I can get on it again!

Great deal on a great bike

I scored this bike for under $400 and I couldn’t be more happy. The bike feels like high quality, no issues when shipped as it was secured great. The bike rides smooth and loving the simplicity.

Loving it!

This is my first single speed/ fixed gear bike (since I was a kid) and it has been a blast to ride so far. I opted for the bullhorn handlebars and swapped out the seat (also added a kicker), but otherwise, it's been great as is. I am actually looking forward to bike rides again!

They shipped the bike to me super fast, it was a great price, i got it built and finally got to ride it and it was awesome. I genuinely love this bike. The company is great, They have a great vibe. As someone relatively new to cycling I had concerns and questions which they answered very kindly. The customer service was fantastic and they were very inviting, which is always important to someone who is taking up a new hobby. I finally got to ride the bike and it was amazing. I genuinely love this bike and this company, I have been singing their praises to anyone who will listen. I'm already looking forward to buying my next bike from them.

First Road Bike - Great Experience

From the moment I first placed the order, to the day of my first ride, this company has been nothing but fantastic! The customer support is unmatched. This is my first road bike, and also my first real bike I’ve ever owned. Mehdi (the co founder) has been extremely helpful answering all of my questions, and even when the bike was sent without the vans handle bars, they were quick to either send me a pair, or reimburse me. This bike is sleek, rides great, and already a ton of fun. My only complaint is the stock seat isn’t very comfortable for me, but is good enough in the meantime. Beyond happy with my purchase, and will definitely be recommending this bike to anyone. I can only imagine what their more top of the line bikes ride and feel like. But, for the money, I don’t think the core line can be beat. Thank you State Bike Co. for continuing to never let me forget how to ride.

Very nice, my only complaint is the screws that tighten the reflectors don’t hold. The brake line bouncing around is enough to rotate the reflector even when screwed as tight as possible. The Alan key fasteners work great though for the important stuff. The water bottle holder is nice and sleek. Overall perfect bike for me to just get outside and go. The earth tone color looks even better in person.
