I have the 2017 model

The Good:

Price, frame, bars, knurling on bars, grips, rear wheel, 2.4 tires, rims, u-brakes, tire clearance for 2.5 and up front and back, full chromoly for cheap! Relatively light, manual, seat, replaceable seat clamp, gyro tab drilled holes.

The Bad:

Ugly welds, too many stickers, front wheel is loose ball, tires hard to remove, brake lever feels odd, seat clamp feels cheap, stem, some hardware feels low quality finish-wise, headset was filthy, sprocket, chain does not have a master link, spokes were loose, pedals are garbage, crank threads were off, fork was spread at the dropouts, Aluminum parts are all cast.

Overall Review:

Overall, for the price, I am very happy! 

I bought the bike off Amazon, the assembly process was quick and required only a 6mm allen and a pedal wrench.

I wanted the frame for my Backup Bike Build. I used the other parts to build up a bike for my son. He loves it!

As long as you dont expect beautifully crafted individually blessed parts and can handle the ugly welds...you got yourself a great bike! 

I recommend for use as a quality starter bike, backup bike, loaner or beater for an experienced rider.

For those who are considering this as a main trick bike and would like to know what they should look at replacing first: 1st-stem, 2nd-pedals, 3rd-chain, 4th-sprocket.

I would imagine everything else would last a good while if taken care of.
