Notice for our customers.

To our knowledge comes news about software fixes being deployed to scooters fleet by their companies across some US and some EU cities – when your scooter is connected to IOT device there is probability that it will update itself and start messing up with unlocking signal cycle sending by our modules. For now affected scooters will get symptoms of shutting down after 20s of work – so to be clear this tool doesn’t work on heartbeat patched version yet, we’ve opened USB port for updates in the future – we are constantly working on firmware.
Please be aware of this and stay “offline” to not pull updates from vendor IOT service.

This tool was created to be a small speed booster (speed unlocker).

Dear customers, this tool is in ALPHA VERSION for the moment, we are developing compatibility for more electric scooters ESC all the time. Please consider your support with new models.
Small discount up to 2020-08-30 due to EARLY VERSION stage.

On beta version there is no guarantee that this tool will be compatible with your ESC however it’s open ported to further update it.

Thanks for your awesome feedback. Stay tuned scooter-rebels!

What this tool is about

This is a hardware component – basically ready to use kit that can unlock full speed potential on an electric kick-scooter which you own. It does work with stock scooter components.
Product is suitable for unlocking speed on “Tier” (and maybe others like “Voi”, “Jump” , for now it’s unknown). This is maintenance-free version.


  • official scooter IOT devices/unlocking module that can already generate heartbeat. For ex. application “MyTier” for Tier company scooters – SPEED BOOSTER will work along side

New “booster” is ready to use, plug and play – it will fit completely inside the steering tube due to small form factor.

Device is designed to be use with bought scooters which have capability to send “heartbeat” sequence (if you don’t have heartbeat enabled scooter you can use regular unlocker like “PARROT“).

This app is dedicated for users with 2 minute shutdown problem who has official IOT heartbeat code generator – this BOOSTER tool is working side by side with it.
So you preserve official app capability (turn on/off) and get speed unlocked and scooter stays on (no issue with 2 minutes shutdown).

For ex. Tier users with access/bluetooth pin code to official app – which already can turn on their scooters – can benefit from this tool by unlocking full speed without 2 min. shutdown issue.


  • ES-200G (Tier/MyTier)
  • contact us if you think your scooter is compatible

End user has to solder only few connection wires – detailed instruction comes with this kit.

Please read FAQ tab prior placing your order, maybe you will find some interesting things there.

    Any troubleshooting steps for 12 E?

  • I’ve 04 E on my display when I depress acceleration switch. Any idea how to sort this out. The name of scooter on the footplate is e-commute. Thanks.

        Hall sensor all good. When throttle disconnected I get 03 E on display, so I throttle is also good. Thanks.

  • Comment on this FAQ

    Yes you can, just use one of touch wire on your button as regular and only one left touch wire as touch input. To be clear, when using both input methods setup: button = 1 pink/purple + 1 grey/white & touch input = 1 pink/purple

    Comment on this FAQ

    If you are into custom settings on newest KINGFISHER or PARROT tool and your scooter need adjustment, follow table below according to ESC model of your scooter.
    Default (initial) settings are 1/1, accordingly: 1 for model & 1 for dashboard.

    ES-100 model: 1 dashboard: 1 Early version works across 1-32 (“alternate mode” will enable linear acceleration*)
    BIRD ZERO unlimited (ES-100; not patched?) model: 18 dashboard: 1 Linear acceleration curve. See also ES-100.
    BIRD ZERO limited (ES-100; not patched?) model: 19 dashboard: 1 Linear acceleration curve. See also ES-100.
    BIRD ZERO limited (ES-100; patched version) model: 21 dashboard: 1 Linear acceleration curve. See also ES-100.
    ES-200B model: 31 dashboard: 255 unlimited speed + max acceleration
    ES-200B model: 31 dashboard: 228
    ES-200B model: 1 dashboard: 255
    ES-200B model: 1 dashboard: 143
    ES-200D model: dashboard: To Be Determined – check other ES-200
    ES-200G model: 3 dashboard: 20
    ES-200G model: 31 dashboard: 225
    ES-200G model: 3 dashboard: 31
    model: dashboard:

    What is the difference between factors? Well, depending of ESC, different factors makes impact on speed and acceleration curve.

    Example ES-100 speeds with [km/h]: 99, 28, 25, 22, 19, 12, 8, 0.

    Comment on this FAQ

    In v8 SEAGULL there is changelog stated: faster scooter (maximum) acceleration instead of previous 70% linear
    You can change it to default 70% (like on rental) by using 30 taps sequence, you should hear confirmation *sound* and acceleration will be now smoother – this can be useful during wet condition or negative temperatures due to traction control.

    In PARROT and KINGFISHER, half of speed settings (depending of scooter) should provide you lower acceleration curve and disabled front wheel “slip control”, in full acceleration “slip control” is always on (ESC setting)

    Comment on this FAQ

    When your backlights and/or front light is blinking every 2 seconds and scooters stays disabled despite unlock code was provided you’ve probably shorted black with green/yellow/green wire.

    Please fix shortage and avoid it in the future – you can damage your tool.

    Category: UNLOCKER tools

    Comment on this FAQ

    To differentiate our tool we create versions based on BIRDs names .


    • SEAGULL = ES-100
    • KINGFISHER = ES-200G
    • CUCKOO = ES-200G/D/B (currently in BETA state)

    Our tools are in developing state all the time so new versions (read changelog on product page) introduces new features and fixes very often.

    If you have further questions, do not hesitate to reach us through support@scooter-unlock.eu

    Comment on this FAQ

    Due to nature of physical and logical properties of this type of sensor it is important that your body (You) have some kind of ground connection – this will amplify sensor reading values and your touch will be register when you meet specific threshold.

    Easiest way to ground yourself relatively to vehicle is to touch some metal part of it – like brake handle, stem, steering tube or even just holding the grips will do the job. Since version v6 touch sensor is more sensitive. Since version v5 touch sensor will not work while accelerating with thumb throttle pressed down.

    If you encounter further problems:

    • please check soldering points on provided metal plate
    • reconnect module from Julet connector (plug/unplug) – it will recalibrate sensor – do the recalibration process after soldering metal plate
    • check continuity of pink (or violet/purple) cables, especially near resistor on this cable
    • contact us.

    Comment on this FAQ

    If you would like to try different speed limits, you can do it on the fly.

    There are 3 different sets of speed limits:

    • No limit + 25km/h limit
    • No limit + 21km/h limit
    • No limit + 18km/h limit

    Press touch sensor 20 times in a row, you will hear confirmation *sound* – that means that your new speed limit is set.

    Reminder: you can toggle speed limit (limited or unlimited) by pressing touch plate 10 times in a row.

    Changes will be lost when you disconnect power from our tool though.

    Comment on this FAQ

    If you are riding your scooter and you can’t toggle on lights or trigger commands, just release thumb throttle button and try again.

    Category: UNLOCKER tools

    Comment on this FAQ

    First of all this feature is available since version 5 (v5), main reason is to reduce idle battery usage of your scooter while using our module.

    Power saving will trigger automatically only while scooter is in disable state. You can “wake up” scooter by long touching metal sensor – scooter is waiting for your unlock code (if this long touch trigger unlock command as well).

    “wake up” state lasts 20 seconds and then scooter goes to power saving state again. Every next sensor touch in this period of time will prolong “wake up” state for another 20 seconds.

    No. Works with stock.

  • Comment on this FAQ

    As mentioned in description of the product (also further in instruction which is available after purchase to download in PDF and it’s attached to package it self) end user have to solder color coded wires (and solder touch sensitive plate or button if opted).

    Remember to wear your helmet!

    Comment on this FAQ

    No, it will be turned on as in normal use.

    Comment on this FAQ

    Indeed it seems that this device is working without original IOT device (GPS tracker) – it can be unpluged (and SEAGULL device need to be plugged instead) to perform diagnosis action with our tool.

    User can confirm it is working without original GPS/IOT module – however keep in mind that the product is sold as it is, without any guarantee of compatibility with your specific copy of vehicle due to possible manufacturer changes.


    Category: UNLOCKER tools

    Comment on this FAQ

    No, this is not OEM (Original Equipment Manufacturer). This is third party tool and we advertise it as to be used for diagnosis.
