When you need a helmet and your gear to travel together, the right backpack can make the difference between a smooth ride and a soggy, uncomfortable day. We spent two weeks riding, commuting, and camping with a range of packs – from ultra‑light 5‑oz fold‑ups to 50‑L touring beasts – testing how they performed in rain, heat, and the inevitable bumps of daily life. Below is the full, hands‑on guide.
How We Tested
We evaluated each pack on a typical weekend bike‑travel scenario: a 150‑km ride that included a sudden downpour, a stop at a crowded campground, and a short hike with a full‑face helmet in hand. For each model we recorded:
- Weight (empty) – how much extra load you carry before adding gear.
- Helmet fit – whether a full‑face helmet slid in and stayed secure while you rode, even with gloves on.
- Water protection – tested with a garden hose for 5 minutes; noted any seepage.
- Visibility – reflective elements inspected under street‑light and headlamp.
- Ease of access – time to open, grab a phone, or stow a laptop while the pack was attached to a bike rack.
- Durability abuse – each pack was dropped from a 3‑ft curb, stepped on, and squeezed in a packed car trunk.
We also noted how the packs felt after a full day of riding – any shoulder fatigue, strap slippage, or ventilation issues. All observations come from real‑world use, not lab simulations.
Peicees Waterproof Folding Motorcycle Helmet Backpack
We folded this pack down, slipped it into a bike rack, then unfolded it at a rainy campground. The nylon canvas sealed out water, and the side zippers let us add a rain jacket without opening the main compartment.
What Sets It Apart: It folds to a pocket‑size 5 × 11 × 18 in while still offering 900 cu in (≈15 L) of interior space – the most compact expansion we saw.
Best For: commuters and road‑trippers who need a dry, ultra‑light helmet carrier.
Pros:
- Ultra‑lightweight (5.6 oz) and folds to a tiny rectangle.
- Waterproof nylon canvas with easy‑to‑scrub surface.
- Side‑zip expansion and included carabiner for quick bike attachment.
Cons:
- No ventilation slits – helmets with built‑in vents sit loosely.
- When folded, internal space is limited; very bulky helmets may need the pack opened.
- No dedicated pocket for a laptop or tablet.

Factors to Consider When Choosing Backpacks With External Helmet Carry (Bike Travel)
Choosing the right pack starts with a few core criteria:
Size and Fit
Make sure the unfolded interior is at least 11 × 18 in and that the folded core stays under 6 × 6 in. A volume of 900 cu in (≈15‑16 L) comfortably fits most full‑face helmets plus a laptop or a change of clothes. Look for an adjustable net or strap that lets you slide a helmet on and off while wearing gloves.
Material Durability
High‑density nylon or 1680D Oxford canvas provides abrasion resistance and keeps water out. Reinforced stitching and sealed seams add longevity on rough trails.
Waterproof Features
Seek a waterproof zipper and a rain‑cover or waterproof liner. Even a water‑resistant shell can protect gear in light rain, but a sealed zipper guards against heavier downpours.
Visibility and Reflective Elements
Reflective strips that cover the sides, front, and rear boost night‑time safety. Pair them with a bright base color for maximum visibility in all conditions.
Portability and Weight
Empty weight under 200 g (≈7 oz) keeps the pack from adding noticeable strain. Keep the total loaded weight under 10 lb to maintain stable bike handling.
Expansion Capability
Side‑zip expansions that add up to six inches can raise capacity from 900 cu in to over 1,600 cu in, useful for multi‑day trips.
Comfort and Back Support
Padded shoulder straps, ventilated mesh panels, and an optional lumbar strap distribute weight and keep you cool on long rides.
Frequently Asked Questions
Can I Carry My Helmet Bag on a Bicycle Without a Frame Mount?
Yes. Use a dedicated handlebar or seat‑post strap, a simple carabiner, or a rear‑rack pouch. Make sure the bag stays balanced and doesn’t interfere with brakes or gears. Test it on a short ride first.
What Helmet Sizes Does the Backpack Accommodate?
Most packs we tested comfortably fit helmets from 4.5 in to 8 in tall, covering street, touring, and BMX models. Adjustable straps or net openings of 17‑24 in make it easy to slide helmets on and off.
Does the Backpack Include a Built‑In Rain Cover?
Several models (e.g., the 50 L tour pack and the SEAFEW 20 L) come with a lightweight, water‑repellent rain cover that folds into a pocket for quick deployment.
Is the Strap Adjustable for Different Waist Sizes?
All the backpacks reviewed feature an adjustable waist strap that slides to fit hips from 28 in to 34 in, keeping the load centered and reducing pressure points.
Can I Store a Laptop Securely Inside the Helmet Compartment?
Only packs with a padded, dedicated laptop sleeve (e.g., ILM MB01, MOSISO, REFLEKTOR 35) can safely hold a laptop. Otherwise, place the laptop in a separate main pocket to avoid pressure on the helmet.
Conclusion
After testing 15 backpacks, the ILM MB01 proved the most reliable for keeping a helmet dry in two inches of rain while weighing under 200 g. For commuters who need extra capacity, the REFLEKTOR 35 offers the best balance of visibility, organization, and hands‑free helmet access. Choose the pack that matches your ride style, weather expectations, and load requirements – and you’ll have a reliable, second‑skin companion for every adventure.
