With the E.R.T. BBSHD kits, you would not be able to reuse your display, throttle, and other accessories.
The E.R.T. BBSHD systems uses the Popular Cycle Analyst as a Display for power readouts, battery level, voltage, current draw, odometer, temp reading, power control, cruise, and adjustable power level.
The BBSHD benefits greatly from higher voltage, which the E.R.T. BBSHD kits support, a 72V will dramatic increase the overall power and torque from your BBSHD.
High Power Hub Motor Setups
 
Why a hub motor and which one is suited for me?
 
  • Hub motors are generally much more reliable than mid drives due to little moving parts (the bearing)
  • Hub motors can be virtually silent with a Sinewave Controller
  • Hub motors can do regen braking
  • Hub motors can be very powerful
  • Hub motors require no maintenance

Why get a hub motor from E.R.T. ?
 
E.R.T. is highly knowledgeable when it comes to Electric Motor drivetrain and performance. Racing is our passion, we regularly take our Electric Race Bikes to the track and compete with gas powered bikes. There, our motors and controllers have been extensively tested to the race track, to the point of failure.
  • QS 205 V3 survived 4 hours of continuous track racing before blowing out a hall sensor. The motor cover then was vented to allow airflow to the motor’s internals, and swapping over to the secondary hall sensor set allowed the motor to run normally.
  • Sabvoton 72V150A survived, albiet the controller needs airflow to survive sustained 11Kw outputs.
All motors and controllers pass a QA checklist prior to shipping out to the customer, to assure customer satisfaction.
 
What is the best setup for a beginner?
The best setup is arguably the EDGE 1500W Motor with our 12 FET Sinewave Controller kit in 26” Wheel Setup.
EDGE 1500W Motor is capable of nearly 40mph on 48-52V and close to 50mph on 72V should you decide to move up from a 48V battery to a 72V battery in the future.
In addition, EDGE 1500W is a high quality motor, that outperforms generic 1000W motors on Ebay and etc.
What is regen braking?
Regen braking allows the hub motor to act as a rear electronic brake therefore slowing down the motor and speed without using mechanical brakes. This allows electricity to be regenerated which would normally be lost through friction brakes.
All of E.R.T. hub motor kits support this feature including: EDGE 1500W and QS Motor Kits.
In addition, the Sabvoton Controller, which is a advanced sinewave controller allows for not only regular regen braking but also variable regenerative braking.

Building the Electric Death Trike took a span of a little over a year. The KMX Typhoon trike was picked up for a measly $700, a craigslist special. Although I have seen these trikes for as low as $500 on craigslist.

The first night I brought the trike home, I installed a Bafang BBS02 and a 48V battery onto it. From there the first version of the Death Trike was born, in its slowest incarnation.

The BBS02 wasn’t particularly powerful, torque was passable in the lower gears and eventually the trike would hit 30mph top speed. However, the trike did struggle with steep hills, often just crawling up steep grades.  Shifting the trike constantly would become old especially when riding it on the street. Additionally, the BBS02 would become hot on extended rides, the small motor could not handle the extra weight and load of the Trike.

                        Death Trike V2  72V Cyclone 3Kw Motor 

 

Death Trike V2 discarded the BBS02 and replaced it with the potent Cyclone 3000W motor, the bike now had dramatically more power compared to the BBS02.

The Cyclone is a bigger and heavier motor, with significantly beefed up internals. Torque, acceleration, and hill climbing abilities have significantly improved compared to the BBS02 but it was significantly louder. Moving up to 72V, the motor ran at a higher RPM so I can could get more use out of each gear. Shifting wasn’t as bad, and it was actually fun as It felt like a Formula-E car with fast and crisp shifting.

Due to the increase power and the long chain line, it caused all sorts of problems including snapping the deraileur hanger, chain tubes,  chain and etc. This has left me stranded on several occasions and I’ve decided to go hub motor to alleviate the problems associated with mid drives.

This is the Death Trike in its current rendition, running a 72V 16AH battery with a MXUS V3 3K Turbo and Sabvoton 72V150A controller. Power has gone up significantly, now the Trike is putting out 11Kw compared to the 3Kw with the Cyclone motor. Top speed is now a little over 50mph, and the Trike gets there in only a few seconds.  The Trike runs smoothly and silently due to the Sinewave Sabvoton Controller. Also, the Trike has forward and reverse.

Front 14
Front 14″ NR77 Moped Tires

Front Wheel Setup has also been upgraded from the stock 16″ Bicycle Tires and Wheels to 14″ Dirt Bike Rims and 14″ x 2.75 IRC NR77 Moped Racing Tires.

Rear Tire has been upgraded from the Shinko 16″ x 2.25 to Pirelli 16″ x 2.75. Rim is a 20″ XL Trippin BMX Rim.

The Sabvoton Controller is completely maxed out at 150A, with regen capabilities for rear braking. With a 74V battery, output was 150A from the battery and 350A to the motor.

The MXUS motor would run a little warm especially at higher power levels, a QS V3 205 motor would take care of any heat issues. Power is more than adequate however, a front steering stabilizer would take care of the front end wobble.

Yes, the trike is driftable.

Thank you for reading this article, I did took the time and effort to write it so hopefully you the reader learned a bit about building the Death Trike, as I did enjoyed riding it.

QS Motor V3 205

bare

The QS Motor that I used during the race was honestly a bit slow, that is because QS did not send me their fast wind motors, which would have allowed me to hit 55mph instead of the 50mph which I was hitting. However, torque and acceleration was very quick. 0-40mph took only 3.5sec and that is without a good launch.

The QS motor when paired with the Sabvoton controller is a match made in heaven. Both QS and Sabvoton companies have a close working relationship together and it is no surprise that the two systems work together in harmony.

The QS motor is quite an impressive motor weighing in at 30lbs, lots of copper mass, and aluminum stator. 50mm wide magnets, this motor does not mess around, and can take quite a beating even under track conditions.

Recently I was able to hit 60mph and later even 70mph on this motor at 116V and the motor was barely warm.

As you can see the QS Motor when paired up with the Sabvoton controller is a very potent platform for some serious performance.

Sabvoton Controller

Although designed as a electric scooter controller, it has found its way into high powered e-moto builds.

E.R.T. carries the latest generation of Sabvoton Controllers that are Current Unlocked, Fully Compatible with the Cycle Analyst V3 Display, Variable Regen, and Temp Protection.

The Sabvoton Controllers come in two different cases, the SSC which is a squarish case, and the SVM which is the rectangular case.

The SSC case allows for a larger aluminum heatsink, which should allow the controller to be run at higher power levels for a longer period of time.

E.R.T. carries Sabvoton Controllers in two Flavors, bare in mind that all our controllers are current unlocked so the 72V150A could be run at 200A for 16Kw. The 96V100A could be safely run at 150A.

Sabvoton 72V150A – 95V 200A Max
Sabvoton 96V100A – 116V 150A Max

sabvoton_sinewave_controller_1024x1024

Installation and Configuration 

Pairing up the Sabvoton and QS motor is quite easy, all the connectors are matching and are plug and play.

Unscrew the bolts on the Sabvoton controller, and screw on the marine lugs from the motor harness to the Sabvoton Controller.

Plug in the hall connector from the QS motor to the Sabvoton Controller.

Wire up the 2 wire Ignition wires to a key switch or a on / off switch. Additionally you can short them together but you would have to unplug the battery each time to turn off the system.

Connect the Cycle Analyst to the CA connector on the Sabvoton.

Plug in Battery and Turn on Ignition

The System should fire up now

All QS Motors when purchased with the Sabvoton Controller is pre-programmed prior to shipping out.

 

Building the Ultimate Bafang BBSHD 74V External Controller Upgrade

         BBSHD 74V With External Controller Upgrade

 

 

 

I had the BBS02 for a few months, and it was a great motor but after a while it just left me longing for more power. So I picked up a BBSHD, and was expecting a huge upgrade but much to my dismay, it barely topped out at 30mph, slower than my BBS02 actually. Torque was improved but only slightly, I let my girlfriend ride it and she said it was barely any faster.

The stock BBSHD stock internal controller is limited to 60V and 30A, which is quite pathetic. Even if your running a 52V pack, you will only get 1500W out of the motor, if that. I also upgraded to a 30T front sprocket and that upped the torque and raised the RPM’s.

The motor felt more responsive and has more torque to push through tough terrain. @48V I managed to hit 28mph which a 3mph loss in top speed compared to the 46T front sprocket. The 30T front sprocket is ideal for off-road riding and trail riding. However, you will not be able to pedal as the motor will be spinning too fast and will be geared low.

At that point, I was still left longer for more power. So I took apart my BBSHD, removing the original controller and putting it to the side. I tested the Cyclone 36-72V 12FET controller, and it ran great however it was very noiser since the Cyclone Controller is square wave, also power delivery would be abrupt at times, again because it’s a square wave controller.

Ultimately, I settled on a 18 Fet Sinewave Controller, and I have 12 FET Sinewave Controllers on the way for testing, and eventually for sale through my site.

Compared to the Cyclone Controller, the Sinewave Controller allows the motor to run much quieter, similar noise level as the stock controller. Throttle response is also much smoother than the Cyclone Controller, which could be abrupt at times. However, the greatest advantage is that the Sinewave Controller can be ran at 74V which significantly increases the RPM’s of the BBSHD, which increases overall power, torque and speed.

On 48V the BBSHD simply runs out of breath way too quickly and power drop offs dramatically after hitting maximum speed in each gear. DC Electric Motors have a certain kV which is RPM per volt, the higher the voltage, the higher the RPM’s. Therefore by moving to 74V the power band shifts up dramatically, you can extend the usefulness of each gear before having to change up. Its moving up to a 600cc from a 250cc motorcycle, you won’t have to shift as often, and can essentially stay in one gear. The granny gear takes me to 18mph and can virtually obliterate any hill, as opposed to crawling up the hill on 48V.

If you want absolute power for your BBSHD, 74V is the way to go. The motor will spin significantly quicker than 52V and you will unlock the power of the BBSHD that is hidden away with the stock controller. It literally will transform your bike into a monster.

Sabvoton Installation Programming and Configuration

Instructions for Sabvoton Sinewave Controller 

5-31-2017 *Updated with MQCON Wiring Diagram*

   Sabvoton Sinewave Controllers are electric scooter / electric motorcycle grade sinewave controllers. They power and control 3-phase brushless motors and require hall sensor input. However they can be retrofitted to Electric Bicycles and when paired to a suitable motor, can give very powerful acceleration and top speed. I recommend the SVMC72150 version, which is capable of 150A battery and 350A phase. Which is @74V 11100W Battery and 25900W Phase before taking into account resistance and losses. This is a very capable Sinewave Controller and has been track tested.

Getting Started With Sabvoton Controllers

1. Phase / Hall Combos

These are the known Phase and Hall combos for the follow motors

Cromotor – Matching Phase and Hall Colors

MXUS 3000 – Swap Yellow and Green Phase – Swap Yellow and Green Halls

QS Motor – Matching Phase and Hall Colors

Cyclone 3000W – Phase all match – Swap Yellow and Green Halls

2. Wiring Diagram

screenshot-2017-05-31-09-01-30

Notes: Red and Black Wires are the battery wires.

1) Connect the orange E-lock wire directly to Red positive to start controller.

*2) If you have a power switch then connect the e-lock (orange wire) to one of the wires on the switch and the other wire from the switch to red positive.

Additionally: If you are using a Cycle Analyst with the shunt Adapter and a power switch then it would be like this.

*Note a power switch is not required but is highly recommended

3. Download Software

Software

2a. Install USB drivers, then install the Sabvoton Software

4. Programming the Controller

Connect the USB programming cable into the controller. The larger part of the cable plugs into the computer’s USB port. Make sure controller has power.

 

Click Set>Port #

This varies depending on your computer, but generally try Ports 1-5 and see if your computer has communicate with the controller. You will know once the software interfaces with the controller.

Parameters

Basic

Lack Volt = Think of this as the low voltage cut off, set this to the minimum voltage you want the controller to cut off power.

Example: Your using a 48v battery, you want to set this around 42V

Over Volt = Over voltage protection, I would set this to 95v or slightly above your battery’s maximum voltage. The maximum setting is 95v.

Example: Your using a 48V and you to set this around ~55v

Rated DC Current = This is the continuous rating for Battery amps, which dictates power. Set this Rated DC current = Max DC current or lower than Max DC Current. Increasing this number will increase wattage power and top speed.

Example: Rated DC Current 50A x 48V = 2400W!

Max DC Current = Maximum amount of Battery amps. Increasing this number will increase wattage power and top speed. But keep this equal to or higher than Rated DC Current.

Example: Rated DC Current 50A and Max DC Current 70A

Limit DC Current = Set this to match the Rated DC Current

Rated Phase Current = Phase amps, this controls the continuous amount of phase amps going into the motor. More phase amps will increase torque and acceleration. Generally you want this higher than Battery Amps, about 2-2.5x higher, but tune to your setup accordingly.

Max Phase Current = The maximum amount of phase current, keep this equal to or higher than the Rated Phase Current.

Functions

 

Electric Brake = Enable for Regen, only applies to Direct Drive Hub Motors.

Flux Weakening = Enable to increase top speed at the expensive of efficiency.  Also known as field weakening. Do not recommend higher than 50A otherwise you can damage or destablize the motor’s magnets.

Flux weakening current = 0-150A, the higher this setting the higher you can boost the top speed of your motor. Technically this counters EMF of the motor and forces the motor to run at a higher RPM.

Electric Brake Ph current = 0-200A This controls how strong the regen will be I generally set this at 100A on a 17″ moto wheel for street riding and 150A for track riding. 26″ Wheel you would want 80A or higher. Be warned, setting this too high will skid the rear tire upon deceleration and can fish tail the rear. Again, tune according to your motor and wheel setup.

Motor 

Pn = Very important to set the correct number of pole pairs for the motor otherwise you will have poor performance. This is the number of magnets in your motor divided by two.

Hall Angle Test = Very import to run the Hall Angle Test map the hall sensors with the controller. Gone are the days of trying various hall and phase combinations.

Try a phase combo then click enable hall angle test, and change control mode to hall angle test. Click OK, then also change the test given current setting from 10A-28A, your motor should spin forward. Very Important to suspend the bike, because the motor will spin on its own for a few minutes.

If Hall Status = Passed then congrats you found the right combination! The Hall Angle setting should have changed to the proper “degree”. Click OK then yes on parameter store. Restart the controller and take it for a spin!

If the motor spins backwards change the Motor direction setting under “Motor”

If the Hall Test fails then change a different phase combination and run the hall test again.

To save the settings, you have to click SET! > DEBUG > Parameter Store > Yes and click OK.  That will save the settings. 

QS Motor Tech Information

QS Hub Motor Tech Info

QS motors are one of the most powerful hub motors available today, I have extensively tested and raced these motors and boy are they powerful. Whether tearing up the dirt trails, blasting down the street, or ripping up the track. This motor can take it, and does its job willingly.

History

QS Motors are produced in Quanshun, or Taizhou China and the build quality is very high. The latest QS motors are the successors to the legendary Cromotor which was the previously the king of Hub motor performance. Now, there is a new king on the throne.

Specs

The QS Motor is a relatively heavy hub motor, weighing in at about 29lbs before the rim is added. This leads to unsprung weight in the rear wheel, which is fine for street riding but handling suffers especially during track or trail riding. You can negate this somewhat by using a long travel rear shock and lacing the motor to a smaller diameter moped rim and moped tire. This will improve traction and durability as the heavy motor will overwhelm bicycle tires and prone to flats.

Technical Specs

  • 205 Magnet Height
  • 50mm Magnet Width
  • Aluminum Stator
  • 0.35mm Laminations
  • Brushless Hall Sensored

Extract and open xpd.py
This is what you would see when you first fire open the software
For the BBSHD Sinewave controller we would be using the “ERT 12FET Sinewave” Profile
For the EDGE 1500W Kit we will using the ERT 12FET Sinewave (Hub) Profile
For the 8000W E.R.T. Sinewave Controller we will be using the ERT 18FET Sinewave Profile
Go ahead and click “Edit”
3. Programming the Controller
Here are some basic parameters and their descriptions.
  • Controller Type: KH612 / KH618
    Let this setting as it is
  • Current / Voltage Design
  • Battery Current Limit
    Battery Current is the maximum amps the controller will pull from battery. 40A is the safe limit for the BBSHD, although the controller can tolerate up to 50A. Use at your own risk, more amps will increase acceleration and torque but will heat up the motor and stress the battery more.
    Recommend 40-50A, if you are running a smaller front chainring you can run a higher Battery current limit.
    18 Fet E.R.T. Sinewave can run up to 70A
  • Phase Current Limit
    Phase current is the current that goes into the motor. Can be safely run up to 100A, higher amps will yield more torque and acceleration, but increase heat to the motor. Lower amps will allow for smoother power at lower speeds, but less torque.
    Recommended 65-90A 12 Fet
    Recommended 120-145 18Fet
  • Enable Softstart
    This delays the throttle ramping so you can smoother acceleration from a stop.
  • Soft Start Time
    This determines the soft start delay. Recommend setting this to 1.
  • Battery Low Voltage
    This determines the low voltage cut off, to protect your battery from being discharged too low. This depends on your battery.
    If you are running 48V then set this to 42V.
    If you are running 52V then set this to 46V
    If you are running 72V then set this to 68V
    *This is optional, if your battery has a BMS then this is not 100% necessary*
  • Speed Switch Mode
    This determines how the speed switch mode works, either switch or button
  • Speed Limit
    100% is max speed however you can increase this to 130% for even higher speeds at the expense of efficiency.
  • Current Limit
    Similar to the Speed Limit, this applies to the current. Can be increased to 120% for even higher currents.
  • Enable EBS
    EBS is Regen braking, this does not apply to the BBSHD as this motor cannot regen.
    Be sure to disable this setting if you do no want to run regen.
  • EBS Force
    This setting determines the regen braking force. Higher settings will allow higher regen braking force.
    Recommended 50-100A
  • Flux weakening
    Flux weakening increases top speed and motor RPM at the expense of efficiency
  • Flux weakening level
    Default is 35 but can be increased to 50 for higher top speeds. Programming the Controller
  • Once you are satisfied with the results click the “Apply” button.
  • You will be return to the main menu
  • Now make sure your battery is unplugged from the controller
  • Plug the programming cable into your controller and also the other end into your USB port on your computer
  • There should be a number in the Serial Port field
  • When you are ready to program click “Apply”
  • You should see a progress bar, it should only take a few seconds to program
  • Now, unplug the programming cable and you are ready to ride!
