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.

The perfect mountain bike for me and my wife.

I'm 59 and my wife is 57 and we are new to mountain biking. After searching for quality bikes at a budget friendly price, we decided on the polygon extrada 7. The bikes arrived within days of shipment and were packaged well and were fairly easy to assemble with tools and pedals included. We have been riding on all the beginner trails we can find and love them. The only thing I wish we had was dropper posts so my wife could feel more comfortable riding downhill, but maybe we can upgrade soon. Very nice bike for the price.

Great entry level bike

Haven’t ridden in about 10 years and this was the perfect entry level bike for the price. When comparing to other brands, the xtrada 7 seemed to offer more such as a 12 speed and great components. The bike is very comfortable and very capable out of the box. The only downside is the size of the seat post being a 27.2, which limited the options on dropper posts when I went to purchase one. I would highly recommend this bike to anyone looking to get into the sport.
