BBSHD FAQ
 
What about E.R.T. BBSHD External Upgrade Kits?
E.R.T. BBSHD Upgrade kits replaces the stock BBSHD Controller which is limited to 52V and 30A current limit.
E.R.T. offers two different External Controller Upgrade Kits
  • E.R.T. BBSHD Sinewave 100V 50A
  • E.R.T. Phase Runner FOC 90V 50A

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.

  1. Hi,

    Wondering if you would/plan to carry external controlers like this one for the BBS02B 36V 500W (1050W nominal) manufactured on 2014 apr 1?

    Occasionally, more than 42V x 25A) W would be badly needed.

    Sure you understand.

    Best, Marcel.
