The Eahora Romeo, a flagship name synonymous with robust performance and urban adventure, has evolved into its new form—the Romeo Ultra and Romeo Ultra II. This upgraded lineup refines every component, from its triple-reinforced frame to its Zhuoyu 3.0 hydraulic brakes and 60V dual-motor system, delivering unmatched safety, durability, and precision. Whether conquering steep trails or city commutes, the Ultra II redefines eBike innovation.
Core Mechanical Upgrades: Safety First, Performance Always
1. Reinforced Frame & Wheel System
A robust frame and wheel assembly is the backbone of any high-performance eBike. The Romeo Ultra II 2025 takes structural integrity to new heights:
- Triple Reinforcement Architecture: Thicker, sturdier tubing enhances impact resistance, ensuring stability even on rugged terrain.
- Ultra-Durable Rims: 3.5 mm-thick alloy rims (vs. industry-standard 1.8mm)paired with reinforced spokes to enhance torsional rigidity and impact resistance, even under 150kg loads or 45° climbs.
- Anodized Aluminum Fork Internals: The air-sprung front fork integrates wear-resistant anodized inner tubes for smoother suspension and longevity.
2. Next-Level Braking Performance Zhuoyu 3.0 Hydraulic Discs
Stopping power meets precision engineering:
- 240mm Thick Rotors + M6 Reinforced Bolts: Enhanced lateral braking force, slower heat buildup, and reduced risk of rotor warping.
- Mineral Oil Brake Fluid: Replaces DOT fluid for better water resistance and corrosion protection.
- Sintered Brake Pads: Wider, thicker, and quieter, with exceptional wear resistance.
- Soft Brake Lines + Instant-Burst Pump: Faster pressure response and shorter braking distances.
- Dual-Piston Calipers: Paired with optimized brake lines, increased oil displacement for consistent, reliable stopping power.
3. Front Fork Performance Matrix
The Romeo’s dual-crown front fork redefines ride comfort:
| Feature | 26" Air Fork | 20" Coil Spring Fork |
| Suspension Medium | Compressed Air | Steel Spring + Hydraulic Oil |
| Weight | Lightweight | Heavier |
| Adjustability | Air Pressure + Damping | Preload + Damping |
| Maintenance | Regular Air Checks | Low-Cost, Simple |
| Ideal Use | MTB, Racing, Long-Distance | Commuting, Cargo, Urban |
4. Drivetrain & Tire Upgrades
- 828 High-Wear-Resistance Tires: 4.0" wide treads with deep grooves improve grip on loose terrain.
- Hardened Clutch Gears: Engineered polymer gears cut drivetrain noise by 25% for near-silent pedaling.
5. Electrified Evolution: Smarter, Stronger, Safer
a. The 2025 model redefines eBike power dynamics:
- 60V 70Ah/80Ah Battery: Features a low-voltage protection switch and improved charge/discharge efficiency.
- ChuanKe Dual Motors (2500W * 2): Monocoque housing design boosts torque to 120N·m, tackles 45° inclines effortlessly.
- Lishui Split Dual Controller: Controllers enable rapid power delivery for explosive acceleration, yet intelligently limit surges to protect components.
b. Intelligent Interaction Ecosystem
The KDS-986 TFT Color Dashboard isn’t just a display—it’s a command center:
- P-Lock Safety: Auto-engages after 30 seconds of inactivity, requiring brake input to unlock.
- Self-Diagnostic Alerts: Real-time error codes simplify troubleshooting for 90% of common issues.
- Bluetooth Connectivity: Track rides via app and compete on leaderboards (20m range).
c. Thermal Management Redesigned
- Controller Cooling: Carbon steel frame + thermal pads under the seat dissipate heat 30% faster.
- Airflow Channels: Redesigned vents keep motor temps stable even during climbing.
Why This Upgrade Matters
Eahora’s Romeo Ultra series isn’t about incremental tweaks—it’s a reimagining of what an e-bike can achieve. Eahora’s Romeo Ultra series prioritizes structural resilience (3.5mm rims, carbon steel housing) and smart safety systems (mineral oil brakes, dual-motor control). With a 50mph top speed (Ultra II) and 75-80km range, it balances adrenaline-pumping power with practicality. The KDS-986 TFT dashboard and 828 high-grip tires cater to tech enthusiasts and urban riders alike, proving innovation isn’t just about power but adaptability.
