Here is my experience so far working a chinese manufacturer called Miracle. I worked with a vendor through Aliexpress called Miracle, which has been mentioned in this forum before. I decided to give them a try after seeing a few positive posts. I had settled on purchasing the MC098, which features disc brakes and Di2 routing.
After building up my bike, I spent some general road riding time with it. I commuted to my work, which is about 12 miles. I had tested it for about 15 minutes in the dirt, in it's short lifetime. On roughly my tenth ride, I was in a parking lot slowing down and dismounting off the bike when I heard a crack. My initial thought was that I ran over something. When I looked down, I saw a large crack, about 1 inch long.
I double-checked their website and felt confident they would help me since this clearly appeared to be a manufacturing defect. You should be able to get off a bike without breaking it.
Anyhow, the company Miracle had this to say after I e-mailed them and showed them the pictures:
Dear XXXXXXX,
Thanks for your information.
I have sent the pictures of the frame for our engineers.And they analyse it,and they told me ,the crack was caused by the strong impact from outside.And the picture leave the proof of impact.
And if it is quality problem,there are only one crack line,instead of Hundreds of crack line.
Sorry about this news.Hope you can understand .
I have not even ridden the bike for a solid month. It's a cyclocross bike and it should be built much stronger than what I just experienced. This is the warranty they have listed on the product page:
Warranty Policy:
We warrant our frame to be free from manufacturing defects for a period of 2 year after the original date of purchase. And we offer 2 year quality guarantee for our frames.
However, the warranty does not cover:
Normal wear or damage or failures caused by a crash, impact,
abuse of the product, non-compliance with manufactures specifications of usage or any other fractious reasons;
When the serial number or production code has been deliberately altered, defaced or removed.
This has been my experience so far. I told Miracle I would post my experience on Roadbikereview, so here it is. I do not recommend them.
