We lstened to our customers and improved and change things as this product evolved. We originally started this project 18 months ago. Thats 18 months of learning and evolving just on this one device. We truly belive this is the very best Sur Ron controler upgrade on the market. we KNOW that other sellers have copied our program (they say, to be copied is the greatest compliment), but now  we have pushed the boat even furthur. Our latest program has been revised to include MORE power! Improved thermal roll back for motor protection, no problems with up hill starts or roll backwards stalls, no cutting out, extra water proofing, higher grade materials used. Stainless steel metal work and extra added powerder coating (you scatch it, it stil wont rust!!).

The acceleration is phenominal, truly FxxxxxG AWSOME! Remember when your bying this kit, It was only us and one other busines (ERT) that created this product for the Sur Ron. Others have copied, but NO ONE can compete against the qulity of these kits.

ASI BAC4000

This controller can take battery swaps ranging from the standard untouched Sur Ron battery,  including a  “Bypassed” Sur Ron battery but is “Tuned” for our aftermarket  battery  @ 72v (max 85V). This is predominatly a 72v Kit and not “tuned” for a std battery. It carrie around twic ethe mount of energy of a standard battery, so lods  more range!! (speed and acceration kills range, so when comparing to a std bike, you need to ride like for like)

The controller now features  a full working display showing: speed, power, battery charge, date and trip. Set with 5 power levels as default that can be flicked at the touch of a button on the fly  (just your thumb, no gloves off or stopping), Can be used like a gearbox to slip up and down the power levels (5 levels set as our default) to suite your terrain and riding style.

The controller comes fully potted and with all leads and looms fitted and waterproofed. The mounts are in place, 3D printed with the possible aditon of protective “Wings” that cn be purchased separatly.

Unlike the BAC8000, the BAC4000 controller under hard use, can get warm and start controller thermal roll back, until you back off and allow the contrtoller  cool. This is controller roll back. This is in addiition to motor thermal roll back where the motor gets too hot and the controler reduces power to help you not cook the motor.

Power levels:

Power Level #1 60V standard Sur Ron Battery (All batteries) Gives approximately double the range of a std bike

Power Level #1-2-3 60V Sur Ron Bypassed  battery and 72v battery

Power levels  #4-5, Only our 72v battery (third party 72 batteries are not supported by us and may be damaged by this set up)

Please note that running on full power for your type of battery, non stop with a wide open throttle is not a good idea and effectively red lining the motor like on a petrol bike. We strongly recomend that you upgrade to our hevay duty bash gurad to increase ari flow over the motor, make your frame stiffer and take heavier knocks. Increased air flow over the motor (cooling) will increase reliabilty and stop thermal roll back kicking in so quick (where poer is reduced tempraliy to help the motor). However if you do ride very very hard and get close to overheating the motor, Our new imporved thermal roll back will gently cut the power until the motor cools enough to accept full power agin. This only tends to happen if yor riding full open throttle down a very long straight (like the M1 motoway).

Unleash more performance and range with correct gearing.  Higher gears (Smaller rear sprocket) does not mean higher top speed. Over labouring the motor with the wrong gearing costs top speed, acceleration and range.

A fast efficient spinning electric motor goes better – simple!.

Our recommendations for a fully equipped 72v system:

For road use:                           10-14 stone rider 52T.           15-17 stone rider 54T.        18+ stone rider plus: 56T

For Off Road/Off Road:       10-14 stone rider 54T.            15-17 stone rider 56T.         18+ stone rider plus: 58T

Pure Off-road/MX Race:      10-14 stone rider 56T.           15-17 stone rider 58T.        18+ stone rider plus: 60T (Max speed 65MPH)

Controller Feature Set

  • FOC (Field Oriented Control)
  • improved torque throughout the rev range
  • Higher RPM compared to the stock controller on 52V and especially on 72V
  • Silky smooth throttle control and responsiveness, like a fine adjustable knob on a light switch.
  • Improved efficiency due to FOC algorithm, premium internal components within the controller (like the mosfets) which increases efficiency while reducing heat losses
  • Loom
  • Mounting Kit
  • Install Instructions
  • Display
  • Both the ASI BAC4000 and ASI BAC8000 use almost the same programming. The ASI  BAC4000 under exceptional hot day and extreme hard use may throttle back and restricted to 431 Phase Amps. the ASI BAC8000 is capable of 850A, but set at 450A. The ASI BAC8000 designed for much bigger motors, will not throttle back and will never be stressed.

Displays

Others copy, se we improve and change. The old APT display (as used by everyone else) had a tendancy to steam up on a hot day if  the  bike had been washed with a hose or exposed very heavy rain, So guess what? we went to another display manufacturer and had another display devolped just for us. We are the only Sur Ron kit that now uses our dedicacted display. Its got our programing and logo on it, so lets see ow long before we are copied again (PS, its really good to use)!

There is no actual need to to reset the display between voltages. However the battery status will show incorrectly if you do not. This is a simple few button press in the settings.

The important factor to remember are:

72V battery: full at 83V-84v and empty at 60v. If you have a battery with no BMS  discharge monitoring (only used to balance charge),  you must stop riding your bike at 59V/60V as going below could damage your battery. With the Electron Cycles 72v battery this is not and issue as the BMS will protect  the battery and cut your motor before damage to battery occurs.

On a Sur Ron “Bypassed” Battery. The battery if full at 67V and dead at 48v, However you will not be able to charge your battery if you go below 54V. This does not harm the battery but you will need to buy or “Recovery Charger”  if you want to get around 30% more range than a std SR battery: https://www.electroncycles.co.uk/product/sur-ron-recovery-charger-for-bypass-mod-flat-battery/

On a Sur Ron standard Battery. The battery if full at 67V and empty at 54v, The BMS in battery will stop your battery from drainingg too far. In reality there is very little gain on running a STD SR battery  with this controller.
