Fit any other aftermarket controller to your SurRon Ultra Bee and the factory traction control stops working. The TC1000 2.0 is the only one that keeps it fully functional.
By working directly with the bike's existing traction system, TORP helps reduce wheel spin and keeps power under control when grip is limited. The result is better acceleration, more stability, and more confidence on loose, wet or uneven terrain.
More power is great. Putting that power to the ground is even better.

Stock vs upgraded battery
Run TORP on the pack that came with your bike, and go further whenever you are ready.
Your stock battery
Every TORP controller keeps talking to your bike's stock BMS, so it safely unlocks more power from the pack you already own than other controllers can reach, with its built-in protection still active.
An upgraded pack
A higher-voltage 72 V or 80 V pack lifts the ceiling considerably, on the TC1000 2.0. The controller stays the same either way, so the battery is an upgrade you can make later.
