KEMIMOTO Ebike Rear Rack Bag 40L EVA Hard-Shell, Quick-Access Battery, Water-Resistant

The KEMIMOTO 40L Ebike Rear Bike Rack Bag is a hard-shell, water-resistant pannier system with a dedicated ebike battery compartment and modular interior that secures gear for daily commutes and long rides.

Designed for electric and conventional bicycles, this rear rack bag balances large capacity with structured protection. Its EVA-reinforced shell keeps contents from collapsing while a separate quick-access battery pocket and internal dividers help organize tools, clothing, food, and accessories. Reflective accents and a shock-absorbing base improve visibility and protection, and an included rain cover keeps everything dry when the weather turns.

How does the battery compartment make ebike use easier?

The bag includes a purpose-built, quick-access battery compartment with a protective separator to prevent contact damage and abrasion. This design lets you remove or install the battery without unpacking the whole bag, and provides an extra layer of insulation and impact resistance.

• Quick-access top flap for fast battery removal
• Padded separator prevents battery movement and friction
• Compatible with many common ebike battery shapes and sizes
• Internal straps hold battery securely during bumpy rides

What fits inside the 40L capacity and how is it organized?

With two fold-out panniers plus an expandable top layer, the bag stores essentials for commuting or multi-hour rides. Interior dividers and pockets keep small items sorted, while the large central space accommodates larger items like a change of clothes or tools.

• Two fold-out panniers for side-by-side storage
• Expandable top section for helmets or extra layers
• Internal dividers and pockets for tools, wallet, pump, and snacks
• Holds locks, sunglasses, spare tube, and lunch without crowding

How protective and weather-resistant is the EVA hard shell?

The bag combines EVA reinforcement with PVC exterior material to form a lightweight, rigid shell that resists deformation and shields contents from impacts. A thick cushioned bottom reduces shock transmission to fragile items, and a stowable rain cover blocks water when needed.

• 85% PVC outer layer for water resistance and easy cleaning
• 15% EVA shell provides stiffness and shape retention
• Thick bottom cushion absorbs bumps and road vibration
• Included rain cover for heavy downpours

Will this rack bag fit my bike and stay secure on rough roads?

The KEMIMOTO bag is engineered to fit most rear frames with widths between 4 and 6.7 inches; bottom straps can be trimmed for narrower frames. Reflective strips on both sides improve night visibility, and adjustable attachment straps and interior stabilizers keep the pack centered on the rack.

• Fits rear rack frames 4"–6.7" wide; straps customizable for narrow racks
• Multiple mounting points for a stable connection to rack rails
• Reflective side strips increase nighttime visibility
• Internal dividers prevent shifting of cargo during movement
