I bought a Custom OG from Mango and I really like the bike. It's an absolute beauty and I really appreciated being able to customize the colours. Quality-wise it is about what one can expect for the price range. It's solid and a comfortable ride. The only drawback that I had was that the forks weren't fully aligned and so I had to adjust them a little bit. When in top gear, the bike chain also rubs against the gear shifter a bit, so I might need to adjust that as well at some point. Overall: 9/10 for the bike itself 7/10 for the assembly 10/10 for customization options 10/10 for delivery speed and convenience
