Not buying.

Do not buy bicycles, in my case the Leon store, they will not repair them well and then it is your fault so that you cannot use the warranty. The change lasted a year. They don't publish negative reviews, this is the fifth time I've tried to write.


Just had my bicycle serviced, the chain turned out to be for an electric bicycle (value 6 to 7 euros) and not compatible with the cassette. Also the gears are of very low quality, low price for bike - clearly money wasted.

The truth is that the bike is going very well, I use it for urban downhill and it is holding up very well. It is true that from time to time I break a couple of spokes but nothing out of this world, it has good performance for a rigid bicycle.

Highly recommended

Assembly done in mag, very quick but we had to re-inflate the tires when they arrived at our home because they weren't done on site, too bad. It’s a good product, we only use it for leisure.

Seat is 5 times more flexible than a standard frame with its narrow 27.2 mm seat post. Low bottom bracket: helps keep the mountain bike stable in turns, and makes it easier to place foot on the ground. Open steering angle (69.5°): keeps mountain bike stable while riding. Short rear wheel base: bicycle is easy to turn. LIFETIME WARRANTY on the frame!

Front suspension

B'Twin U-Fit 80 fork, with 80 mm of travel and an innovative fork stiffness adjustment based on the rider's weight (121 to 230 lbs.). Durable thanks to the materials and fabrication processes used. Equipped with a mechanical spring and elastomer stoppers for maximum reliability and minimum maintenance.

Rear suspension

No rear suspension.


9 speed single-chainring
