Assembly

Your bike needs minor assembly before riding; use the tools and videos included.

As a guide, it'll take 10-40min depending on whether you're an experienced bike assembler or have little to no mechanical experience.

Side Note: Your cables will stretch during the initial bed-in period and must be adjusted by an experienced mechanic around 150km of riding.

All around excellent experience :))

I bought an Xtrada 6 three days ago from here. Not only do I have it already, but its built up and has already been on my fav local single track this evening !! Super quick easy build because these guys did all the technical stuff and did it correctly, i.e. Rode great with absolutely no adjustments needed. Fantastic bike, fantastic dealer and fantastic price. Im an avid cyclist... road, crit, track racer and now I'm back on the trails. So glad I found this site. Thank you x10000 G-

Exactly what I was looking for!

Great experience. This bike is exactly what I was looking for to tackle low-key dirt roads and the occasional trail en route to backcountry fishing spots! I love it so far. Customer service was excellent.
