I've never ridden a Chedech but on face value looking at the design and features it doesn't exude a feeling of quality, it looks a bit crude with poorly designed paintwork and missing features. Carbon fibre should be your concern if you are riding it, I'm pretty sure many brands of carbon fibre bikes recommend frequent visual checks of the frame to make sure cracks aren't present, these checks are more designed for lightweight road bikes I'm sure but you have to be a little more careful with carbon fibre due to its more brittle nature.

Even the best carbon frame manufacturer in the world (Giant bikes) writes this in their manual;

After any crash, take your bike to your dealer for a thorough check. Carbon composite components, including frames, wheels, handlebars, stems, cranksets, brakes, etc. which have sustained an impact must not be ridden until they have been disassembled and thoroughly inspected by a qualified mechanic.

That's any crash not severe crash and notice they don't even mention steel or aluminium but the first part of the text implies you can still ride them but they should be inspected by a dealer. So many more things you have to be careful about with carbon, bolt torque levels, not clamping the bike in a bike workstand and many other issues caused by a material that has little strength when pressure is applied in the wrong places on the bike. I've seen it written in a few places that you need a different mindset when riding a carbon bike to a aluminium or steel bike because the components can fail catastrophically without warning and this could be in the middle of busy traffic. I've certainly read of people hitting a pot hole with their carbon forks and instantly the forks failing and the rider plummeting to the ground at high speed and sustaining injuries. Lets not forget carbon fibre manufacturing is a manual process building up layer by layer of carbon fibre matting etc, it is much more likely to have a flaw due to this manual labour intensive process. It is low paid work where as an aluminium frame welder is much higher skilled and rewarded financially and many steel frames are robot welded at the big factories like fuji-ta. A steel frame can be welded in seconds, an aluminium frame welded in minutes and a carbon frame manufactured in hours and that's why carbon frames are currently the most inconsistent quality of any frame material.

This is quest composites that make Trek and Canyon carbon frames amongst others. Notice the working conditions, seats they are sitting on and the poor fitting of the hat of the woman closest to the camera meant to protect the forks from stray hairs and dust which can cause the carbon to de-laminate and crack. This is not a good environment for quality or consistency.
