That Bird frame without a “brain” is a classic situation when a friend brings you a cool base, but there are no electronics, and you sit there thinking about how to bring it all to life with an Etwow controller or a simple ebike display. I myself once struggled with a similar customization: I assembled a lightweight Bird motor with a battery, but after several unsuccessful attempts to connect it, it still didn’t work properly because the controller wasn’t stable. In the end, I decided not to waste my nerves on DIY projects and just sell the whole set for crypto because I didn’t have enough money for a normal upgrade. Then https://paybis.com/sell-bitcoin/ became my savior — I quickly transferred BTC to my card without any extra fees, verification took a minute, and the money was credited to my account almost instantly. Now, instead of a broken Bird, I ride a full-fledged scooter, and I remember those nerve-wracking evenings with a soldering iron with a smile. If you also have a frame just sitting around unused, it’s better to monetize it and move on, don’t torture yourself.
