Write a 300 -400 word super SEO friendly and engaging product description.

I am a small online independent retailer specialising in bicycle accessories and bicycle-related products. I am looking for a talented copywriting individual to assist me with writing up a winning sales pitch with the limited material that I have about this new product. The product actually comes without a manual so I have gathered as much written material to aid the talented copywriter to write up a good sales pitch from the limited documents that I am able to provide. You will have at least one week - that seven days to complete this project. You must be able to write this sales pitch using super SEO friendly and engaging product description using UK English and in a language in which second English language users should be able to understand without referring to a dictionary or google words up.
