Firmware 2.4 is a controller update, not a hardware change. It is free, it takes six minutes, and it makes the bike noticeably easier to live with on loose ground.
Changes
- Regen torque ramp reduced by 18% in the first 200 ms of a descent
- Cold-start throttle map smoothed below 5 °C
- Battery state-of-health reported to the display after each full charge
- Service mode now logs the last 30 fault codes with timestamps
How to update
Connect the service app over BLE, keep the bike on the stand, and leave the pack above 30%. The controller reboots twice. Do not update with the throttle engaged, which sounds obvious and is the one thing people get wrong.
