Focus Jam² 6.8 Nine e-bike: first ride review - MBR

Jun 2019 · Danny Milner

New Focus Jam2 is balanced, versatile e-bike that gets back to the essence of trail riding. Good value and boasts excellent new Bosch Performance CX motor.

Highs
  • Versatile, back-to-basics trail e-bike with strong motor and excellent range from 625Wh battery.

  • Good value.

Lows
  • Not the most agile, dynamic e-bike.

  • Control units are still oversized and vulnerable.
