If you ride a Sur-Ron Ultra Bee, you already know it’s one of the most capable electric dirt bikes on the planet right out of the box. But like all performance machines, it rewards upgrades. When you start pushing harder, riding faster, or exploring more challenging terrain, upgrading key components transforms your bike from fun commuter to serious trail machine.
Below are some of the most impactful upgrades available for the Ultra Bee — parts that improve power delivery, suspension control, traction, and overall ride confidence.

🔌 1. Ventus Aetos Controller — Better Power Delivery & Smooth Throttle
One of the first limitations riders encounter is the stock controller. While stock units are tuned for reliability, they often leave performance on the table — especially when you want crisp throttle response and usable torque on technical terrain.
The Aetos Controller delivers:
-
Improved throttle smoothness and torque response
-
Better low-speed control in loose and technical terrain
-
More predictable power delivery
-
Compatibility with stock wiring and battery systems
Whether you’re climbing technical lines or charging open desert terrain, the Aetos controller unlocks a more refined and capable power curve.
🛠 2. RFloXa Suspension — Transform How Your Bike Handles
If there’s one upgrade that makes every other mod feel better, it’s suspension. Electric bikes are torquey and fast, and stock suspension often becomes the first weak link under harder riding.
Upgrading to RFloXa Ultra 43 forks and Raf55RV rear shock gives you:
-
More travel and damping control
-
Increased stability at speed
-
Better line holding over rocks and ruts
-
Reduced brake dive and smoother landings
RFloXa suspension is engineered specifically for high-performance e-motos — not repurposed gas components — so you get real ride quality gains on trail, desert, and jump lines.
🦵 3. Warp 9 Elite Pegs — Precision Foot Control
Footpegs are one of those parts riders overlook — until they feel how much difference they make.
Warp 9 Elite Pegs offer:
-
Wide platform for better traction underfoot
-
Aggressive tooth pattern for boot grip in mud or dust
-
Strength that handles hard landings and aggressive cornering
Better peg traction = better weight placement = more confidence on every line.
⛑ 4. Warp 9 Tapped Handlebars — Strength + Comfort
Great handlebars are about control and comfort. Warp 9 tapped handlebars give you both strength and a superior feel — especially on longer rides or rough terrain.
Benefits include:
-
Reduced rider fatigue
-
Stronger clamp interface to prevent twist
-
Clean internal routing for controls and cables
-
A comfortable, confident riding stance
These bars feel like an upgrade from the moment you mount them.
🚴 5. 21″ Front & 18″ Rear Wheel Combo — Better Traction & Geometry
One of the biggest handling improvements you can make is upgrading wheel sizes.
A 21″ front and 18″ rear wheel setup delivers:
-
Better rollover over rocks and roots
-
Improved handling geometry
-
More tire choices for trail and off-road conditions
-
Enhanced high-speed stability and cornering
This setup is standard in dirt bike performance builds because it works — and your Ultra Bee benefits the same way.
🧠 Why These Upgrades Matter
Each of these parts affects how the bike interacts with the trail:
-
Aetos controller unlocks usable torque
-
RFloXa suspension keeps the bike stable and composed
-
Warp 9 pegs & bars improve rider control
-
21″/18″ wheel setup enhances traction and handling
