Beta units ship now at $699. Lite, Full, Pro and Desktop follow at release, each at its own price. Everyone on the waitlist saves $99, whichever they choose.
Desktop software that connects straight to your DBB and turns the sessions you've logged into a picture of your battery over time. See DBB Desktop.
Sessions sync from the DBB to your own computer over a direct connection. Your data goes from the bike to your desk and nowhere else.
Desktop looks across every ride and charge you've logged, not just the last one, so you can see how the pack is changing from month to month.
A clear summary of where the pack stands, to keep for yourself or hand to a buyer or a shop.
Five zones carry state and nothing else: nominal, good, advisory, warning and critical. They're chosen to stay distinguishable across the common forms of color blindness, and critical is violet so it can't be confused with brand color or a brake light in peripheral vision. Every zone also has a position, a label and a value, so color is never the only signal.
It doesn't control your bike. It reads, displays and logs, and where the BMS and EVCC allow it, sets the parameters you ask it to, within bounds. The DBB is an instrument. It isn't a controller or a safety system.
