The 2013 Grenade B2 is the third in Grenade”s lineup of “entry level” street/trail BMX bikes, but as you can see, the B2 is not your standard entry level bike with its Cromoly Main Tubes and 25/9 Micro Drive System and its features do not stop there.

The Grenade B2 Bike is as at home on the street as it is on the trails, with its agile but stable geometry and its quality packed components.
HOW TO CHOOSE THE RIGHT BICYCLE TO START PRACTICING BMX?
- The size of the painting
It is measured with the horizontal tube , ie the upper tube that joins the steering with the saddle. The larger the tube, the more space you will have to pedal between the pedal and the handlebar.
- The height of the handlebar
The height of the handlebar determines the height of the driving position . An 8-year-old will be more comfortable with a low handlebar, while a teenager or adult will prefer a higher handlebar because they have the highest bust.
- The length of the pedal rods
Normally it varies between 160 and 180 mm. Short cranks allow children or small people not to juggle their bikes. The very large connecting rods are more annoying for the practice of freestyle, but allow a better acceleration in race.
- Different BMX teams according to the disciplines
Some disciplines require particular BMX teams. This is the case of freestyle, especially in street, flat and skatepark. The bikes designed for these practices are equipped with a rotor (a braking system that allows a 360 ° turn of the handlebar ) and of pegs (some calapers necessary to make figures and, occasionally, to take to the friends).
- The practice of freestyle requires a reinforced material that supports impacts and falls: a reinforced saddle, double-walled wheels with 36 or 48 spokes, or an ultra-resistant plate.
- For dirt, trail and race, tires are usually used with cleats , since the bicycle has to adhere to the earth and mud. In ” street “, in ” flat ” and in skatepark, bicycles are equipped with slick tires to ensure maximum adherence to the asphalt.
