One more remark... I had 650kms with by TC, after exchanging the display (instrument cluster) I have 0 km (or 5kms after short ride today).

In other words PAY attention when buying a S&H bike with few kilometers on board. Look at tyres and overall conditions, because maybe it had 2000 kms in the past, with the battery charged 200 times from 0 to 100% (so full cycles which already diminished the cells to their 80% capacity), but once the display is changed it looks like new 🙂
