Proviz Electroluminescent Rucksack



Good rucksack cum safety aid, ideal for shorter commutes

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Hailing from the mean streets of South London, Pro Viz’s cycling rucksack is certainly an eye-catching package for the short haul winter commuter looking to haul lap-tops, camera equipment and other sensitive equipment you wouldn’t leave to chance in a pannier. Alternatively, super-efficient packers could even cram a change of clothes, an A4 document folder and some other stationary inside the well- organised compartments. However, a few minor refinements would greatly improve comfort over longer distances and broaden its appeal to mountain biking/trail running too.

In essence we have a sturdy, yet lightweight bag constructed from rip-stop nylon with acres of day-glow yellow with a bit of Scotchlite dotted around for good measure- run of the mill but mightily effective nonetheless. The electro luminescent technology boils down to two electrical strips hard wired into the front section of the bag. A small yellow battery pack cum switch clips into the front section. Padded polyester mesh adorns the back panel and shoulder straps and while elasticated mesh pockets capture keys, phones, patch-kits, stray Allen keys and other oddments.

As a safety tool, the rucksack almost wins top marks-I’ve used this technology before and in either flashing or steady modes, the electric blue light coupled with the other reflective technologies means you’ll make an impression on the darkest night or dullest December morning. Being picky, a dash more hi-viz detailing on the side panels would ensure comprehensive visibility-especially negotiating roundabouts, junctions etc.

Traffic sits up and takes notice from around half a mile or so and the run times are pretty reasonable-forty seven hours in flashing from the original batteries. Judging by the test period, the fabric should comfortably deal with the rigours of daily commuting-brushes with brickwork, sides of stationary busses etc. Weatherproofing seems generally excellent with contents remaining bone dry through persistent downpours and there’s been no hint of electrical gremlins. However, the airflow didn’t match that of similar cycling specific models and sternum straps would eliminate annoying sway when porting heavier loads.

The first electro luminescent rucksack on the European market.

Can't argue with the first statement and the second looks to be true, even if the technology has been employed for a few seasons.

Generally to a pleasing standard.

Rate the product for performance:
Rate the product for durability:

Sturdy enough on the strength of the test period.

Rate the product for weight, if applicable:


Rate the product for comfort, if applicable:

Generally good but leads to a clammy back after a while and sternum straps would combat sway when heavily laden.

Tell us how the product performed overall when used for its designed purpose

On the whole the rucksack is a real boon for short-haul commuting thanks to clever lighting technology, good quality materials and construction. Sternum straps and better airflow to the back are my suggestions for improvement and the electrical components mean it can only be wiped down but these are relatively minor points.

Tell us what you particularly liked about the product

Solid construction and very, very eye-catching.

Tell us what you particularly disliked about the product

Bag sway when heavily laden-easily overcome by employing sternum straps.
