I seem to have experienced this same issue this morning. i ran the bike down to 1% charge on my last outing as iv always been told that its good to run a full recharge cycle on any battery every now and then. Put it back in the garage (on charge), pulled it out before work this morning and it wouldn't turn on, just a solid red light when pressing the power button. tried various different procedures on connecting the charger then turning plug on at the wall, or other sequences, tried holding power button, tried performing a reset but nothing.
Not happy at all, if anyone had seen my last post on here it was a long while ago when i received the bike on delivery, with in 30mins of riding the powertrain module completely pooped its self. so i had to wait weeks for a new one to arrive which my local dealer done for me as its quite an extensive task to change and i didnt feel that it was my place to repair a brand new bike id just spend £10k+ on.
Fossil fuel bikes are calling me again i feel.
