Important - Please Read

  1. Upgrading the controller will void the warranty on your Bafang motor.
  2. At the moment the controller does not support headlight or tail light output due to signal interference issues. We are working on it but this is a 2021 item.
  3. Archon X1 controller is warrantied for 2 years from date of install. If you want to buy a warrantied motor+controller, you can purchase one here.
  4. We do not fix any broken motors. We will test each motor prior to starting the swap. If it fails, doesn't start, has missing parts, or has other damage, then we will return the motor to you and refund you, minus return shipping fees.
  5. The upgraded motor cannot be tuned using the old Bafang software or cable harness. It has brand new custom firmware specifically developed for Watt Wagons.
  6. As we upgrade the firmware and add features, we will make these upgrades available via a paid upgrade path.
  7. If you purchased a new Bafang Ultra motor, or an ebike with the Bafang Ultra motor in 2020, please ensure you have the UART version of the motor.

Early Customer Testimonials

"The bike pulls & accelerates. The power is there whenever you want it & will even compensate for poor gear & line choices. It helps you navigate technical sections & accelerate up hills. There is an immediacy to the power that just builds, like a Tesla which in part explains their appeal."

@JoeKing   -   APR 2020

"It does seem to have smoother power delivery.
It is not as grabby when you pull away. And it definitely feels more refined more intelligent and a little more powerful. My bike has a new character and I like it."

@TomW  -   Jun 2020

"I rode a M1 Sporttechnik before switching to the Ultra with X1. This... I have no words. I used the Exess HP-180 (Travalanche) and the bike pretty much outperformed any M1 on any day of the week. Yeah!"
