We have been testing the 2025 Surron Ultra Bee heavily over the last year and have found the upgrades that truly transform this into a phenomenal machine.
Starting with the Basics, removing the 19" Front wheel and replacing it with a 21" is crucial. We are surprised this bike doesn't come this way from the factory but doing this upgrade slacks out the stance of the bike for better high speed stability and provides a nearly endless amount of 18/21 trie combinations.
In this video we are Testing the Race Spec suspension. This is beautiful Kashima Coated F43 Fork and R46 Shock provide precision tuning, incredible bottom out resistance, and a stiffer chassis for less flex ultimately leading to more control, better feel, and incredible stability.
We have also put the EBMX X-9000 V3 controller onto this bike. This controller allows you to choose the OEM Display and Functions or Utilize a smaller sleek Colored display and free up a lot of space on your Handlebars. But more importantly it allows you to precisely map the throttle and pull up to 900 Phase amps of torque and 27Kw out of the OEM Battery and Motor. The bottom end pull feels like a rocket ship only to be matched with a strong but controllable top end providing a great combination of higher top speed and more acceleration.
These upgrades are some of the best options for your Surron Ultra Bee!
