Blue Jay - Core-Line
Stunning Vibrant Blue, White and Chrome

The Blue Jay is a twist on one of our original 4130 Core Lines, "The Tsunami". The bike is versatile and tough, yet classic at the same time. It's built on a durable steel frame in a classic hi-gloss blue finish, chrome components, a flip-flop hub for freewheel or fixed-gear riding, and Van's "waffle pattern" grips. All for less than $300. If you're looking for a fun and well-built bike, but aren't yet looking for a "race-ready-bike", the Blue Jay from the Core-Line series is for you. <

Fantastic Value

If you aren't able to commit more money to a bike, this is a great option. I bought it as my first bike, and have been slowly upgrading the parts/ personalizing the look as I go. The only thing I had to change right away to enjoy the ride was the seat and the pedals. The other modifications were nice to have's. I was originally pretty regretful about going with a hi-ten steel frame instead of a nicer material, but after upgrading the wheels, stem, and handlebars, I got the weight down to sub-20 lb's and I couldn't be happier with the bike. I'm still rolling on the stock drivetrain and have not complaints about it.
The frame color is also gorgeous - I get compliments all the time.

Easy & Fun

I love my new Core line from State Bicycle. Easy to order, delivery was fast and I was able to put it together myself. The bike rides great and I love having the flip option for Fixie or Freewheel. Thanks State Bicycle!

Blue Jay bike is awesome!

Such a well built bicycle. I did upgrade a few things like the flat tire package, pedal upgrade, water bottle holder and kickstand... The bike was delivered 2/3 assembled and they specify that it must be assembled by a bike shop professional to qualify for the 5 year warranty. I'm a Harley mechanic and wouldn't let anyone touch my blue jay... lol
I'm quite sure they would honor my warranty if need be.. I love my blue Jay and the compliments keep coming. I encourage the purchase of this bike!!! Oh and by the way I wont bolt the kickstand on because I dont want to scratch the beautiful paint...👍👍👍👍😊😊😊

Blue Jay - core-line

Probably the best bike for the price that I’ve owned! It’s my everyday commute bike. I’ve had zero problems with it, I get compliments on how nice the bike looks. Very satisfied with this purchase.

beautiful florida bike

I was looking for a single speed bicycle that I could use when visiting our new home in florida. I purchased a beautiful blue and white model online. It was delivered and I rode it all over town with no issues. i'm looking forward to the same dependability every time I visit.

Very impressed with performance.

The bike is great quality and I have no complaints as far as that goes, but I will say the only reason I didn’t give a 5 star rating is because you provide little to no actually instruction as far as the bike goes.
Im no beginner nor am I a professional but lucky for me one of my best friends is a bike mechanic.
With little to no instruction besides basically “go to someone else to build your bike” you guys also provide no sort of content what so as working on the bikes or info on them.
Besides that can’t complain about the bike tho, can’t provide basic instructions so maybe new comers can feel comfortable to learn but you better get that review!!


Super good looking bike! Rides amazing overall solid bike, everywhere I go people always compliment it. No issues at all, totally worth it!

Amazing bike

Couldn’t be any happier and this bike gets a lot of looks everywhere I go!

Blue Jay

Great bike! Got tons of compliments the first day I took it out. Bike shop that assembled it for me on Miami Beach said it’s a solid bike. Rides comfortable. Very happy!
