• Had an idea and wondered if anyone has done/seen similar - I want to mount my di2 battery in the fork steerer and use it as a cache battery to power a phone/GPS while riding, as well as shift gears... I also hope I can charge it on the go with a dynamo front wheel... and it would be cool to power a front and rear light as well...
    that sound doable?
    Cheers in advance!

  • It sounds doable but I'd rather use a separate battery than Di2 for Garmin charging. At least you'd know where you are when your gears run out of juice :)

  • But imagine the excitement when both of them die at once out of range of a phone mast.
