With the Sonic Evo AM SX enters BULLS the territory of light e-mountain bikes for the first time. The e-bike draws its special power from the new Bosch SX engine, while the frame and geometry are designed for easy handling. And that's not all: BULLS also has a lightweight hardtail bike with a Bosch SX engine presented. At first glance, the new BULLS could easily be confused with the well-known lightweight Sonics, thanks to the linear design and the filigree top tube. But don't be fooled: the frame of the new one is completely new. The massive head tube of the classic e-bikes was reduced to 1,5 inches (approx. 4 cm) scaled down and the carbon structure is specially designed for use with light e-mountain bikes in order to save considerable weight.

The latter leaves it with slight Mavic carbon wheels, Rockshox Ultimate suspension and the new one Sram XX transmission but nothing more to be desired.
