Stage 1 ASI BAC4000 Controller Kit for Sur Ron
The EVFREAKS Stage 1 ASI BAC4000 Controller Kit will take your Sur-Ron Light Bee to the next level. It's made for riders who desire more power, quicker throttle response, and smoother, more controlled acceleration. This upgrade changes your ride into a high-performance machine, whether you're on trails, journeying, or pushing the limits on the weekend.
This kit is pre-programmed by EVFREAKS and is geared up to use right out of the box. It can give you up to 15kW of peak power and 420 phase amps, which is an enormous boost over the stock setup. It works with both 60V and 72V battery systems, meaning you can customize the experience to fit your build and style.
Important attributes:
- Flexible Voltage Compatibility: Designed to function flawlessly with 72V aftermarket upgrades or 60V OEM batteries.
- Gains in Performance:
- With the stock 60v battery, power and torque are increased by 50%.The top speed was raised by +15mph(22km/h)
- When combined with a 72v system, up to 120km/h (75 mph).
- Full Integration of Displays :
- One fixed power mode without a display( meaning controller will have only 1 power mode - the one it's set to).
- The EggRider V2 Display.
- The EggRider C1 Display.
What is Included:
- The ASI BAC4000 Controller Unit is potted for durability and completely waterproof.
- An in-house-built custom IP65 wiring loom with a direct throttle connection for a neater setup.
- Thumb Throttle with Regenerative Braking: This feature locks the back wheel while decelerating, recharges the battery, and adds motor braking.
- Mounting Kit: Top and bottom brackets made of premium PETG that are 3D printed for an ideal OEM.
