Bullit MX ... the sound of send
Shimano ep8 motor
The Heckler MX and Bullit MX are powered by Shimano's new EP8 drive unit, which is lighter, more powerful and has lower volume and less drag than its predecessor, the E8000 motor.
MX = Variable Wheels
A 29 inch front wheel ensures optimum traction and roll over while a 27.5 inch rear wheel keeps the chainstay relatively short ensuring a snappy and easy-to-handle bike on tight, demanding trails.
