• My dad's Di2 needs to be stored for 2-3 years until his eponymous grandson grows into it. What's my battery management strategy?

  • Sell battery

    Is anybody going to want a 6 year old BTR1, however lightly used?

    buy new one in 2-3 years?

    As a corollary to the above, will I still be able to buy an external battery in 2026? I just want the bike rideable for a year as is, then he can make his own decision about rewiring for an internal battery without dragging me into the project 🙂
