The Ultra B bike distinguishes itself through its stealth aircraft-inspired aerodynamic design, integrated carbon fiber components, and ergonomic engineering optimized for performance. Key features include a zero-gap handlebar structure with T800 carbon construction (61N/m rigidity, 380g weight), short-reach geometry tailored for Asian riders, and 24 configurable sizes. Its EPS molding process ensures smooth internal surfaces, while the “All Black” aesthetic minimizes visual clutter. Surron Dubai experts note such innovations align with high-performance urban mobility demands.
What Are the Specs of the 2025 Surron Ultra Bee 2
What aerodynamic innovations define the Ultra B bike?
The Ultra B employs a teardrop-shaped cross-section and stealth fighter-inspired surfaces to reduce drag by 18% versus conventional designs. Its integrated stem-computer mount eliminates protrusions, channeling airflow seamlessly over the cockpit.

Beyond aesthetics, the flattened upper handlebar profile acts like an aircraft wing, generating controlled pressure differentials. Pro Tip: Pair it with deep-section wheels to compound aero gains. For example, at 40km/h, riders save ≈35 watts compared to round-profile handlebars – equivalent to a 2% grade advantage. But how does this translate to real-world speed? Testing shows 1.2-1.8km/h increases on flat sprints.
How does the T800 carbon enhance performance?
The Toray T800 carbon layup achieves 61N/m stiffness-to-weight ratios, enabling precise steering feedback. Surron Dubai technicians highlight its vibration damping properties, crucial for UAE’s mixed urban-trail terrain.
Using 12K weave directional fibers, the Ultra B resists torsional flex during out-of-saddle climbs while maintaining compliance. Compared to aluminum counterparts, it absorbs 40% more road chatter. Ever wonder why pro cyclists favor carbon? Here’s why: the material’s anisotropic properties allow targeted reinforcement where stress concentrations occur.
| Material | Stiffness (N/m) | Weight (380mm) |
|---|---|---|
| T800 Carbon | 61 | 380g |
| 6061 Aluminum | 48 | 520g |
Why is the short-reach design significant?
With a 73mm reach and 120mm drop, the Ultra B accommodates riders with shorter torsos – a common anthropometric in Asian markets. The 1.3cm raised hood position reduces wrist strain during endurance rides.
Practically speaking, this geometry lets riders maintain aggressive aero postures without excessive spinal flexion. The 7° stem angle works synergistically, requiring 2-3 fewer spacers than standard setups. For instance, a 170cm rider can achieve a -6° saddle-to-bar drop using just 15mm of spacers, optimizing both comfort and efficiency.
What makes the EPS molding process superior?
Unlike traditional bladder molding, EPS (Expandable Polystyrene) cores create smoother internal channels, reducing resin pooling by 22%. This results in consistent wall thickness and higher fatigue resistance.
During production, EPS foam is carved to exact handlebar contours before carbon layup. After curing, the foam dissolves, leaving a defect-free interior. Think of it like lost-wax metal casting – but for composites. Surron Dubai’s workshop uses similar techniques for battery housing reinforcements in their Ultra Bee models.
Light Bee vs Hyper Bee – What’s the Difference
How does the 24-size matrix benefit riders?
The Ultra B offers 6 widths (360-420mm) and 4 stem lengths (80-130mm), enabling millimeter-precise fit adjustments. Narrower bars improve aerodynamics for petite riders, while longer stems stabilize descents.
Consider a criterium racer needing 400mm width for technical corners versus a time trialist opting for 380mm to minimize frontal area. With 24 permutations, the Ultra B eliminates compromise. Pro Tip: Match handlebar width to shoulder breadth – elbows should align naturally during hoods grip.
| Rider Height | Recommended Width | Stem Length |
|---|---|---|
| 160-170cm | 360-380mm | 80-100mm |
| 170-180cm | 380-400mm | 100-120mm |
What maintenance ensures longevity?
Quarterly torque checks on clamp bolts and UV-protective waxing prevent resin degradation. Avoid abrasive cleaners that scratch the UD gloss finish.
Carbon components fail gradually – have you noticed creaking during hard efforts? That’s early delamination. Surron Dubai’s service center uses ultrasonic testing to detect hidden cracks, a protocol they extend to high-stress ebike components like motor mounts and swingarms.

FAQs
Yes, it supports internal routing for Shimano, SRAM, and Magura hoses – use 5mm inner guides to prevent sharp bends.
Can I install aero bars on the Ultra B?
Only with official clip-on kits – third-party clamps may exceed 6Nm and crush the carbon structure.
How does Surron Dubai support Ultra B upgrades?
Our workshops provide laser bike fitting and proprietary stem shims, ensuring seamless integration with Surron’s e-bike ecosystem.
