Safety Notice
This motor controller is powerful enough to melt a motor, wires, destroy a battery and break bones. With
great power comes great responsibility! Don’t try to break stuff, because you will!
The controller comes with a default configuration that should work for even the wildest users. As you can
tell from the extreme power density achieved, these motors, wires and power electronics are already
being pushed to the limit.
We are offering it for people who know what they are doing and will be responsible with this kind of
power (know what gear to ride in, understand battery limits, etc).
We prefer to sell this kit to our existing bike customers only. If you are a new customer you may need to
convince us that this is the controller you want. This is for people who have owned the stock or ludicrous
V1 BBSHD and want more.
Luna is supporting a fully Open Source platform named VESC®, which means users could potentially
change any parameter of this motor drive, and have full access to the source code to change or improve
fundamental features. Luna builds come in read-only mode to deter people from changing safety-critical
parameters, but we know its only a mild entry barrier.
Modifying the default motor configuration is NOT advised as it greatly increases the likelihood of
property damage and severe injury -and source code changes are far more dangerous-.
It is NOT legal to ride this on public streets or trails. We sell this bike for private property use and
race/track riders.

Installation
You can follow the BBSHD controller replacement video:
Replacing the controller is easier if the chainring is removed, so if you plan on changing your
chainring size, this is a good time to do it.
It’s worth mentioning that the Ludicrous V2 can extend the top speed by about 25% for the same
battery voltage, so you could get more torque from a smaller chainring while keeping the same end
speed.
Typical BBSxx recommendation for improved water resistance is sealing with silicone or dielectric
grease, particularly around the grommet but also possibly around gasket, with some dielectric on
connectors as described here:

Note that there is no shift sensor cable installed. If you really want it you can use one of the brake
cables.

Using the BBSHD Ludicrous V2
The controller works out of the box, its plug and play with no tuning needed.
It is designed to work in the same way as the stock controller: throttle accelerates, it has pedal
assist, you can choose your power level and the display shows the same variables.
Because it's the same principle with a lot more power, here are few suggestions:
● Check the maximum current you can draw from your battery.
If for example your battery can only provide 80A, set the corresponding battery current limit
with Android App (see below)
● If your display is set at the maximum power level, be careful the first time you use it. In a low
gear it can kick you off the bike.
● Be mindful about the amount of power dumped into your motor. If you drive high currents for
too long the winding temperature rise will engage the motor over temperature protection.
Motor temp is easy to see in the app gauges and in the logs.
Changing controller parameters has been disabled in our firmware builds, for safety you won’t be
able to increase any motor related setting like max currents, temps, control loop parameters, etc.
The complete set of motor parameters is hardcoded at build time so it works out of the box and
stays that way. We do acknowledge that a motivated user could build the open source firmware, but
it’s not recommended as it’s easy to damage a mis-tuned controller.

Power Levels
The BBSHD platform allows the user to set assist levels, typically 5, but most displays can be
configured to use 9 levels.
When set to 9 levels, it modifies the torque (or phase current) produced by the bbshd in the
following way:
PAS LEVEL
Available torque
LEVEL 9
100%
LEVEL 8
88.8%
LEVEL 7
77.7%
LEVEL 6
66.6%
LEVEL 5
55.5%
LEVEL 4
44.4%
LEVEL 3
33;3%
LEVEL 2
22.2%
LEVEL 1
11.1%
LEVEL 0
Throttle and PAS disabled

Connecting to VESC Tool
Get the VESC Tool Luna Edition Android app from here: Download the app installer
DON’T USE THE GOOGLE PLAY APP!!:
Here is a video tutorial to cover the basics of the connection:
WIRELESS CONNECTION - VESC-Tool Mobile Tutorial
(Again, DON’T USE THE GOOGLE PLAY APP!)
1. Open the VESC Tool App and tap SCAN
2. When your VESC shows up, click

CONNECT. Note there may be more than one
Bluetooth Low Energy (BLE) device in the air.
3. Your BBSHD is now connected! After a
couple of seconds the controller will transfer
the custom Luna UI to the phone.
4. In the RIDE tab you can see live data
coming from the controller. We added a Motor
Temperature gauge, as the Ludi V2 can easily
drive the motor to its temperature limits.

VESC Tool is also available for Linux and Windows PCs here:
VESC Tool Downloads
The app will NOT run on IOS smartphones because Apple doesn’t allow open source licences in
their App Store.
Vesc Tool on Mac laptops is not officially supported, but someone provides unofficial Mac
releases here:
https://github.com/rpasichnyk/vesc_tool/releases
We didn’t test these so use them at your own risk.

Tuning Your Controller
In the TUNE page you can store 3 different tuning profiles:
● STREET LEGAL
● TRAIL
● LUDICROUS
The profile names are fixed, but the actual tuning is fully configurable.
By tapping the WRITE button, the selected profile will be stored in the controller.
