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.

Great entry level starter mountain bike.

Packaged extremely well, came with a tool kit and pedal wrench that was not expected. Awesome! I went over bike and I didn’t find and loose bolts. Derailed was set great. My only small complaint is there was weld spatter on the from by the head set that was never cleaned off and painted over. I would absolutely recommend this bike to anyone in the market.
