Love the company used it when I was younger and 15 years later still love the company I bought a bike it shipped within 2 days, had one minor problem but the company got back to me about the problem and fixed the problem no hassle and faster than I could have imagined 10/10 will shop again.

Got the bike on recommendation and found out its composition. Also the box came to me kind of thrashed. They replaced it no problem, well I’m still waiting on the credit so I say no problem we will see… I decided to get the Stolen Saint 24” and I have to be honest the bike is solid they just advertise it with a rail compatible seat post and they gave me a bottom of the line flared tube with and Ace Hardware adjuster. Mike has been super but I’m thinking they need to retrain who puts what in the box because I make my bike choice on those parts.. seems to be a theme.

I'm a 48 year old guy who used to ride and race BMX a LOT when I was young. I decided to get back into the BMX game with this 24" Cyngus from DK. For this price point, I was expecting more. I remember the days when $300 bought you a top of the line Diamondback, or even more recently $500 bought you a top of the line GT race bike. Apparently those days are gone.

There were 4 issues when I unboxed this bike. 1) Scratches on the frame and forks (most likely FedEx, but better care could have been taken by DK or Dans Comp). 2) Front rim is either severely out of true or bent ( again probably DK issue but Dans Comp should have caught before shipping. I called Dan's and was told to have a LBS try to true rim and they would reimburse me. 3) Seatpost clamp bolt STRIPPED!! This blew me away. Stripped before I touched it. Fortunately I had the exact same size stainless bolt and nut in my tool chest (got really lucky) so crisis averted. 4) One of the front fork dropouts was too tight from the factory. Some delicate belt sanding was required to get the front axle to slip in. Totally on DK, BUT, Dans should have caught it.

So overall this bike gets a solid "MEH" thumbs up from me. It's a good looking bike, rides nice, and I can't wait to hit the pump track and jump park with it. Purple paint on frame is gorgeous. Pedals lacking and will be replaced with Chromags. Nice cranks. Nice brake. Nice DK headset. Nice bars. Rims lacking. Seat works (now).
