OSF Features and Configurations on Display (list and explanation of current features)

TSDZ2 Open Source Firmware (OSF) is a project being developed by members of the TSDZ2 Community. Discussed, tested, and continuously updated - upgrades have already been implemented that grant the TSDZ2 a smooth power delivery system that even rivals the expensive mid drives found on higher end factory bikes... but where it really shines, is when it comes to the custom settings. Current Features Include:

- Smooth, Efficient, Responsive (FOC) Power Delivery System using Sophisticated Algorithms

- Can accept Wide Voltage Range between 24v - 60v and Provides Advanced Battery Settings Including Low Voltage Cutoff, and Pack Resistance, for Accurate and Detailed Battery Information including State of Charge (SOC) Option

- All Custom Settings can be Changed from the Display Menu, with Quick Access/Select for Maximum Motor Power, and Graph Display Toggle

- Set Maximum Power Level (Watt Limit) and Current Ramp (Amps) for High Power with Smooth Onset

- Boost Mode can be Programmed for Additional Power to be Activated when you Initially Start Pedaling ~ 'Takeoff', and can be Disabled/Enabled, with an Adjustable Fade-out Duration

- Option for Temperature Sensor Utilization (Replaces and Disables Throttle) to provide Power Rollback Preventing Damage from Overheating at High Power Levels
