Who is Jeffsy?

Who the hell is Jeffsy? And what have YT got up their sleeves?

YT have been known for their pretty interesting and ‘out there’ advertising campaigns over the years but this one has got to be one of the most flamboyant we’ve seen (and it seems to be doing the trick, because this is everywhere!). #IHATEJEFFSY is a short film without any bike riding or even any references to bikes, but hinting at a third member of a couple’s relationship (see image at the below).

What could it possibly mean?

Is Jeffsy a Downhill bike they’ve been working on with Gwin? Or maybe something YT have missing from their range? Like a 650+ bike? Or even a 29″? We aren’t sure, but YT will reveal all on the 7th of April.


Is this Jeffsy?


Who is JEFFSY?

Bike manufacturer YT causes quite some confusion. With the slogan #IHATEJEFFSY the company out of Forchheim is currently promoting their latest campaign. They have been pretty restrained on giving out any information about their coup. The hate-slogan in combination with some furious-looking ladies is definitely raising a lot of questions. One thing is certain though: On April 7, 2016 the big news will be revealed. The countdown until the date has started on

“I really hate JEFFSY”. There could not be a more shattering judgment. On one can get ready for the launch of something huge. Usually, YT sends across nothing but chilled vibes with their Good Times attitude, however with JEFFSY they seem to unleash a rather unpopular object into the mountain bike world. During the video-interview, sweet Sidney explains why she hates JEFFSY’s guts. Since JEFFSY showed up, it has clearly been going downhill with her boyfriend because he rather spends his free time with JEFFSY than with her. Obviously, frustration is inevitable and she is definitely sick and tired of it. However, her boyfriend Trent can’t stop thinking about his new best buddy JEFFSY: All or nothing, exploring the unknown, overcoming obstacles, being on tour together and just having a good time – sounds quite like the best friend ever.

Those who wish to participate in the HATE-LOVE debate, can do so by using the hashtags #IHATEJEFFSY or #ILOVEJEFFSY on Twitter, Instagram and Facebook. YT will elect the best post and a JEFFSY will be raffled as first prize.

On the 7th of April, YT will reveal the secret about the love-hate relationship about JEFFSY. Stay tuned! More information about JEFFSY can be found on
