I would just like to post some good news My Focus Jam 2 has just turned 3000 miles in less than 2 years without any issues whatsoever with the Shimano motor, battery or display. Fair wear and tear items such as chains and cassettes have been replaced but otherwise the frame, bearings, shocks, dropper post are all original and have performed exactly as they should. A bit different from my previous Bulls which had a new Brose motor, new display and new battery within 6 months of purchase! Here's to the next 3000.
