I know bikes, I know Japanese, and I lived and road in Japan.

The translation is largely accurate (just minor structural stuff that doesn’t matter).

The only content that might matter, and it doesn’t really seem to, are the hashtags for the tweet that were not covered above (roughly “connect with bikers” and “quick biker self-intro”).

While I agree with your general characterization of Google translate when dealing with Japanese content, in this case it did a decent job, largely because the content was very simple and straightforward.
