West Biking Long Riding Double Pannier Bag (50L) — Waterproof Rear Rack Bags
50L of Waterproof Storage That Mounts in Seconds
The West Biking Long Riding Double Pannier Bag gives you 50 litres of weatherproof carry capacity split evenly across both sides of your rear rack — no bungee cords, no balancing act, no bags shifting mid-ride. The twin bags clip directly onto any standard eBike or bicycle rear rack and stay locked in place until you take them off. Commuters, delivery riders, touring cyclists, and grocery runners: this is the bag that finally makes your rear rack useful.
Built from 1000D folded mesh with a PVC waterproof laminate, the bags keep your gear dry through Canadian rain, slush, and the freeze-thaw downpours that other bags give up on. Integrated reflective logos on both sides add rear visibility in the dark — essential for delivery riders doing evening shifts or commuters riding home in November. When you arrive at your destination, the bags unclip and carry by hand. No tools. No fuss. On the rack in five seconds, off the rack in five seconds.
Available in Black Gray and Black Orange. Free Canada-wide shipping.
Key Features
- 50L Total Capacity — 25L Per Side — Each bag holds 25 litres of gear. Together: a week’s worth of groceries, a full day of camping gear, or a double-shift delivery load. The wide opening on each side lets you pack quickly and access items without digging to the bottom.
- 1000D Folder Mesh + PVC Waterproof Construction — 1000D Denier fabric is the same heavy-duty material used in military gear and professional cycling luggage. The PVC waterproof laminate underneath keeps water out when Canadian weather does not cooperate. Rain, light sleet, road spray from trucks — your gear stays dry.
- Fits Any Standard Rear Rack — The mounting hooks are designed to fit the rack rails on all standard eBike and bicycle rear racks. Compatible with the rear racks on the Movin’ Pulse Fat Tire, most commuter eBikes, and any bike rack with standard horizontal rails. Takes under 10 seconds to mount or remove.
- Reflective Logo Strips — Both Sides — High-visibility reflective accents on the exterior of each bag. At night or in low light, headlights from following vehicles catch the reflective material and make you visible from a distance. Not a gimmick — a genuine safety feature for any rider not on a dedicated lit path.
- Waterproof / Portable / Carry Off-Bike — The bags are not rack-only. Unclip them from the rack, carry them by the top handle, and bring them straight into the grocery store, the office, or your apartment. No rack, no problem. They work as standalone carry bags when you need them to.
- Lightweight at 2,035g (~4.5 lbs) Combined — For 50L of carry capacity across a pair of waterproof bags, ~4.5 lbs total is light. You are not adding significant weight to your eBike, and the mass is distributed symmetrically on both sides of the rear axle for balanced handling.
- Compact Folded Size: 49.5 × 33 × 8 cm — When empty, the bags fold flat. Store them in a desk drawer, a closet shelf, or your eBike’s storage compartment. Pull them out only when you need them.
- Two Colours — Black Gray / Black Orange — Black Gray is the understated everyday commuter option. Black Orange has high-visibility colour contrast that works well for delivery riders and riders who want extra daytime visibility alongside the nighttime reflective strips.

Who Is This Bag For?
- eBike commuters — Carry your laptop, gym clothes, lunch, and everyday kit without a backpack. Both bags clip on before you leave home and unclip when you arrive. Your back stays dry and your shoulders stay free. Works perfectly with any step-thru or commuter eBike that has a rear rack.
- Delivery riders — 50 litres handles a full food delivery load or a multi-package courier run. The Black Orange colour option maximises visibility on city streets during evening shifts. Reflective strips keep you visible when headlights hit the bags from behind. Wipe-clean material handles spills quickly between stops.
- Grocery and errand runners — The wide opening on each bag fits grocery bags, produce, and oddly shaped items that a backpack cannot handle. This bag is what makes an eBike a genuine car replacement for weekly shopping. For the full cost comparison, see our eBike vs Car guide.
- Long-distance and touring cyclists — The product is named “Long Riding” for a reason. 50L of weatherproof storage distributed symmetrically across the rear axle gives you stable, predictable handling on multi-day rides. Clothing, tools, food, and camping gear — it all fits and it all stays dry.
- Cargo eBike owners — Pairs directly with rack-mounted cargo eBikes. If you ride the Movin’ Pulse Fat Tire or any eBike with a 50 kg rear rack, the Double Pannier Bag gives you the soft cargo system to match the bike’s carrying capacity.
Who this bag is NOT for: Riders without a rear rack — you need standard horizontal rack rails to mount these bags. Riders who need hardshell waterproof protection for cameras or electronics — the 1000D mesh is water-resistant and weatherproof for normal riding conditions but is not a sealed dry bag. For camera equipment in heavy rain, a dedicated dry bag inside the pannier is recommended.
Rack Compatibility
The West Biking Double Pannier Bag fits any rear rack with standard horizontal rails — which covers virtually all eBike and bicycle rear racks sold in Canada. If your rack has two parallel horizontal tubes running left-to-right at the rear of the bike, these bags fit.
The mounting hooks are adjustable to accommodate different rail heights and thicknesses. If you are unsure whether your specific rack is compatible, contact our team before ordering — we will confirm fit based on your bike model.
What’s Included
- West Biking Double Pannier Bag — Left bag + Right bag (pair)
- Mounting hooks (pre-installed on bags)
- Your choice of colour: Black Gray or Black Orange
Frequently Asked Questions
Will this fit my rear rack?
Yes — if your rear rack has standard horizontal rails (which covers nearly all eBike and bicycle racks), these bags will mount. The hook system is adjustable for different rail diameters and heights. Contact us with your bike model if you want confirmation before ordering.
Are these bags truly waterproof?
The 1000D mesh shell with PVC laminate is waterproof for normal riding conditions — rain, road spray, light sleet. They are not designed for submersion. For electronics and gear that cannot get wet under any circumstances, use a waterproof inner bag as a secondary layer. For clothes, food, tools, and everyday commuter gear, the bags handle Canadian weather without issue.
Can I use just one bag on one side?
Yes — each bag mounts and dismounts independently. Use both for maximum capacity, or use just one side when you have a lighter load and want to keep the bike’s balance profile simple.
How do I clean these bags?
Wipe the exterior with a damp cloth. The PVC laminate and 1000D mesh do not need machine washing — surface dirt and road grime wipe off easily. Do not machine wash; it can degrade the waterproof laminate.
What eBikes do these pair best with?
Any eBike with a rear rack. Our most popular pairings: the Movin’ Pulse Fat Tire for delivery riders, and step-thru commuter eBikes like the Eunorau Meta and Freesky Nova B-360 for daily commuters. If you are shopping for an eBike to pair with these bags, see our eBikes under $2,000 guide for commuter options that include rear racks from the factory.
