Read our recent blog post : Power Tips: Get Your ASI Controller Upgrade Tuned by a Pro

We looking at +30-50% increased torque & acceleration and +7-10mph top speed from this upgrade.

No matter how many Sur-Ron upgrades you install on your e-bike, one basic part might be holding you back. The controller is the ‘brain’ of the bike, which controls your total power output, torque, top speed, acceleration, and accessible energy.

The BAC9000 delivers perfect amps with smooth performance running evfreaks file, whether you’re speeding across a flat course or revving up for jumps - we got you covered. Up to 32kw peak & 800 phase amps.

Every customer gets a custom tuning and programming session, which we can do remotely connecting to your phone or tablet. Because every Sur Ron or Segway engine is slightly different so for the best customer experience you need that individual setup based on your hardware parameters & your own individual needs which we will discuss during the session. Our engineers are also available to troubleshoot, resolve, and improve any potential issues that riders notice on the road afterwards.

This controller kit comes with a Bluetooth-compatible LCD EggRider V2 screen, so you can easily swap between pre-programmed modes & power levels with a single touch.

The new electric Alta throttle we including in our kit addresses common software bugs and helps to keep smooth acceleration with continues speed and is built to last.

BAC8000 controller (7.2KW tune or up to 18KW with upgraded battery)
Most Advanced Tune on the market
