- Requires careful handling to avoid impact damage
- Professional repair may be needed for damage
3. Steel Frames: Classic Durability
Though less common in modern e-bikes, steel remains a favorite among traditional cyclists and custom builders.
Steel Advantages:
- Exceptional Durability: Steel provides the best balance of strength, weight, ride comfort, and affordability
- Superior Shock Absorption: Natural flexibility provides comfortable rides
- Easy Repair: Most repairable frame material
- Long-Term Value: Can last decades with proper maintenance
Types of Steel:
- High-Tensile Steel: Basic, affordable option
- Chromoly Steel: Lighter, stronger premium steel alloy
Limitations:
- Heaviest frame material option
- Less common in modern e-bike manufacturing
- Potential for rust if not properly maintained
4. Titanium Frames: Aerospace Engineering
The premium choice for riders seeking the ultimate in performance and longevity.
Titanium Benefits:
- Unmatched Strength-to-Weight Ratio: Lighter than steel, stronger than aluminum
- Corrosion Proof: No rust concerns ever
- Lifetime Durability: Virtually indestructible under normal use
- Smooth Ride Quality: Natural vibration dampening
Considerations:
- Highest cost among all frame materials
- Limited availability in e-bike market
- Specialized manufacturing requirements
