There's no doubt the Chinese are attempting a global takeover. One look on sites like eBay shows 9 products in 10 with a 20-30 day delivery time and to their credit they are giving people what they want - products that look like the brand name counterpart, have similar functionality and are a fraction of the cost.
I even own a set of indicators on my bike that cost me £2 including shipping from eBay, and there's no way I could have done that cheaper - and I own my own bike shop!
But look closer at these products to and you'll see where the costs are being cut. Replicating something on the cheap can be done well, but can also be done cheap. Mouldings aren't quite accurate or poorly finished, seams don't quite line up - I also bought a phone holder for the bike, and there's no way I'm trusting it with my phone!
Which brings me to the image attached. This product, available on the phone app Geek, is a strap system that attaches your child to your back so you can ride your bike knowing that should your little one decide to not hold on s/he will be securely strapped on.
Firstly, this is pretty stupid. This is basically offering your own child as a replacement for your back protector. I imagine that my own daughter would not stand up to me using her to slide down the A34 on my back after a SMIDSY.
Secondly, this product is available to buy for just £7. First statement aside, would you trust your kid to be safe with something that cost less than the shirt he is wearing? Will the seams hold? Will the clips take the strain? Will the stitching be as good as Alpinestars?
The point here (apart from the screaming absurdity of the product) is that Chinese replicas are cheap for a reason. Think that this thing is not only made for £7 - materials, sourcing materials, tooling for manufacturing, packaging, management, global shipping, this thing is still making the company a profit on a sale price of £7. How cheap can each of those components be?
The point is this. If you are going to drip yourself and your bike in Chinese kit, think about the consequence of it failing, and think whether spending a little more on a quality product, like the ones BikeTuna supplies, is worth that little bit more. A bar end, OK... an indicator? Probably... a brake lever?
