Just my 5cents....
The design is Chinese I would think, but the chip technology is pretty recent. It should do the music and phone stuff pretty wellÂ
The CSR8635  is a low cost part that was designed as a BT Speaker solution, with a single mic (no wind noise noise reduction) so think what you can do with a speaker and you will  not go far wrong.
The apt-X codec claim is wrong...the 8635 does not support that, they would need to use the CSR8645.
Bike to Bike....nope, and they will not have the range beyond about 10m to connet to an audio source,they are not class 1.
Rider to pillion...nope
The Bike specific headsets use a more flexible solution (typically the DSP/FLASH memory part CSR8670) which not only does more in terms of connectivity and functionality, but costs more, as does ensuring a waterproof product.
Horses for courses, as usual.
