​​Hello comrades!

We have made a prototype and are starting to test the USB2CAN module, which allows you to connect the controller to a computer via a USB port to configure and update the firmware. So far the software is only available for Windows. You can already make an order on our website, after finishing tests the modules will go on sale. Approximate price — $25.

#usb2can

​​The program interface follows the menu structure of the on-board computer. On the left in the window, select the device, and on the right you see its menu. You can expand each item and make settings.

Hello, riders!

We recently released big firmware updates v0.8.10 and v0.8.11 for the Controller and v0.80B for the Onboard Computer. Due to the fact that more and more settings and new menu items appear in each new firmware, we decided to post not only a list of changes but also a more detailed description of the updated devices menu. We hope this will help you quickly understand the settings and try out the new functionality. We have also updated the description of the new menu for all devices in our Wiki.

The New World Record for Sur-Ron Light Bee X with Nucular controller!

The fastest speed that was ever captured on a modified Sur-Ron Light Bee X with Nucular controller 24F:

141 KM/H (88.125 MP/H)

This speed was verified by 2 GPS satellite devices that were on the Sur-Ron X during this successful attempt (can be seen in the first 15 seconds of the video):
#Dragy DRG 69
#Garmin Edge 1030

This was performed on a closed road with full protective gear.

This extremely modified Sur-Ron X weighs 70.5 KG and has produced a peak of over 20KW for over 15 seconds. We can't disclose the rest of the specs and settings at this time, as we're hoping for a more serious achievement! 😎

We are very proud of this achievement of our customer from Israel. Thanks to all the people who took part in this world record!

Hello riders!

Hello, riders!

Another big firmware update v0.8.12 for Controller, aimed at optimizing performance and fixing bugs. But, not everything is so boring, we have added some new features. The first feature is MPPT (Maximum Power Point Tracking) for charging the ebike battery from solar panels. We will tell more about this technology in the very near future, along with the announcement of a special module for pairing the controller and solar panel. The second feature is a new "Power + torque" throttle mode. More about it is below.

​​Hello, riders!

After 12 months of development and launch production, we present you with a new controller — Nucular P24F, which replaced the previous version of the 24F controller. Taking into account our experience and, of course, your experience, we have revised the approach to the design of the device. The new P24F has been designed from scratch and features a completely different design that offers many benefits.

All information at the link below. Let's add two important spoilers:
- controllers in stock, no waiting, shipping after order.
- new kits have been developed for Sur-Ron Light Bee and Talaria Sting.

Hello, riders!

We are developing a new website and plan to make a “Projects” section, where we will post a description of your projects for the construction of EV transport using Nucular controllers. It could be anything — boats, bicycles, electric cars, electric air transport. We will be very grateful if you send us your story and attach photos, or a link to the video. If the #project description is in video format, please provide it with text information. Don't forget to indicate the type of controller (6F, 12F, or 24F), battery tech specs, the brand of electric motor, and the result you achieved (power, speed, range). Also, tell us how to sign your story. For example, your name/nickname, and link to Instagram/Facebook (if desired).

If you are developing projects on a commercial basis, we are ready to place links to your website and your company’s social networks (Instagram, Facebook) at the end of the article.

You can send the information to info@nucular.tech. The subject of the email: "My project". You can attach a photo to the email or provide a download link. Be sure to include your name and the country where the project was realized.

To thank you for your work, we will select the 10 best projects and organize a vote in the general chat. As a gift, the winner will receive a P24F controller, for second place we will give an On-Board Computer, and for third place a uLight lighting control controller.

We are waiting for your projects, thank you!
