Folding Bike × Rear-Drive E-Assist Integration

Designed From The Frame Structure Up With Future Rear-Drive E-Assist Integration In Mind.

No More Hesitation On Climbs, No More Limits On Distance.

A Well-Designed E-Assist System Is Not Just About Installation, But About Overall Integration, Stability, And Ease Of Use. Therefore, The Frame Is Designed From The Beginning With Consideration For Battery, Motor, And Controller Integration, While Balancing Battery Placement, Cable Routing, Rear-Drive Compatibility, And Post-Folding Mobility Convenience.

Battery Mounting Space
The Front Triangle Frame Supports Bottle-Type Battery Mounting For A Clean And Natural Integration. The Battery Supports Quick Removal For Convenient Charging And Replacement Without Affecting Folding Operation.
Cable Routing Design
The Frame Features Enlarged Cable Ports That Can Accommodate Up To 6 Cables, With Pre-Planned Routing For E-Assist Systems To Minimize Exposed Wiring And Maintain A Clean Overall Appearance.
Rear-Drive Compatibility
The Rear Frame Structure Supports Rear Hub Motor Installation And Uses A 135mm Rear Dropout Standard. Recommended Configurations Include 36V, 250–350W Rear-Drive Motors Paired With 7–10 Speed Cassette Systems For Easier Installation And Maintenance.
Post-Folding Mobility Convenience
The Overall Design Balances Folding, Commuting, And Storage Needs. After Installing The E-Assist System, Riding Becomes More Effortless, Allowing Riders To Handle Longer Distances And Varied Terrain With Ease While Maintaining The Mobility Advantages Of A Folding Bike Through Pedal-Assisted Riding Support.

Built As A Folding Bike Truly Designed For E-Assist, Rather Than A Compromised Aftermarket Conversion.

Folding Bike × 100G E-Assist Conversion Advantages

① Up To 720Wh High-Capacity Battery | Long-Range Riding Without Range Anxiety

The Seatpost-Mounted 10Ah (360Wh) Battery Easily Handles Daily Riding Needs. For Extended Range, An Additional 10Ah (360Wh) Battery Can Be Added Inside A Seatpost Bag, Expanding Total Capacity Up To 720Wh For More Confident Long-Distance Riding.

② Single-Cable Installation × Internal Cable Routing | Clean And Minimal Appearance

The Electrical Control Wiring Is Integrated Into A Single Cable Layout, Combined With Changebike’s Developed “Large-Port Internal Cable Routing Stopper” For Easier Installation Without Additional Drilling Or Frame Modification. Internal Routing Keeps Cables Hidden For A Cleaner And More Consistent Overall Appearance.

③ Rear-Drive Motor System | 135mm Standard Design

The 100G Rear-Drive Motor Uses A 135mm Standard Design Compatible With Standard Rear Dropout Widths. The Installation Follows Common Market Standards, Making Future Parts Sourcing, Maintenance, And Replacement More Convenient.

④ 100G Geeko E-Assist System | Globally Accessible

The 100G Geeko E-Assist System Can Be Easily Purchased Through Cross-Border E-Commerce Platforms Without Regional Restrictions, Making It Easier To Purchase, Maintain, And Use Worldwide.

⑤ Folding Without Compromise | Easy To Move Even After E-Assist Conversion

Although Installing The E-Assist System Increases Overall Weight, The Folded Size Remains Unchanged. The Change Gravel Folding Bike Can Still Be Easily Rolled And Moved After Folding, Balancing E-Assist Performance With Daily Practical Convenience.
