    • Overall nice bike for the price!
Overall nice bike for the price! As always you need to put on your bike mechanic hat to assemble and tune it up. Here are a couple details you might have an issue with. The cable driven disc breaks are ok. The front brake caliper was assembled incorrectly and was not operational when the bike arrived. I was able to disassemble and reassemble correctly (works now). The front shock works but it is the lowest quality shock I’ve seen (consider purchasing a used one online and replace). The stock pedals are cheap plastic (upgrade immediately to reduce slips and risk of injury). The red rear reflector (came with two rear reflectors, both same size?) do not fit. The white front reflector fits fine. After a good look the bike seems solid, nice welds, paint, tires are ok etc. ... show more

    • Bike handlebars arrived backwards
Bike arrived with handlebars installed backwards. Also both break pads came stuck in the engaged position. Luckily I know how to take the bike apart and fix everything. But very disheartening to get a new bike and have to spend a couple hours fixing it.

Review Image by Han Solo Han Solo
Bottom line is decent bike for the sale price. This was my replacement or exchange, the 1st one shipped with a noticeable scratch in the frame. This one was a little better only having scuff marks on the frame, forks and cranks and a less than perfect weld that is visually not appealing (my OCD). I love the purple color and sale price were the reasons I purchased this bike. The frame material is high quality but if you ride this bike a lot you will want to upgrade some of the components. 1st thing is the none adjustable seat angle will violate you or cause you to slide into the rear tire. The headset, cranks, stem and pedals are cheap and I will be replacing with upgraded parts. The wheels, forks and brakes are adequate although I had to adjust my brakes right out of the box and it looks like I need to have my front rim trued. Tires are good chain and shifting components are good, surprisingly my bike shifts very well right out of the box. To sum up my review I'm a little disappointed with the bike and would not pay full retail for it. If you can get it on sale and are willing to upgrade some components you will have a nice mid level dirt jumper. ... show more
