Bell Arella Urban Sport Helmet



Good value, lightweight, commuter helmet with excellent features but sizing issues mean you should try before you buy

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.

The Arella is essentially the female specific version of Bell's Muni urban helmet, and is aimed squarely at commuters, urban riders and recreational cyclists in both its styling and features.

On first glance, it's fairly standard looking mid-range helmet, with the emphasis on generating a feeling of safety rather than on high performance. That said, it has some nice features missing in many helmets that sit in this niche. Most innovative and making the helmet good value at this price, are the flashing red lights integrated into the nylon web of the helmet at the rear. These are easy to switch on and off, although not with gloves on, and the batteries are easy to get at for replacement purposes. The only problem with them is that they are not always readily visible if a high-necked jacket or top is being worn. A nice additional safety feature though, and backed up by a light bracket higher up on the cranium for even more visibility with the addition of a small led light (not supplied).

The removeable visor is a feature that slightly surplus to requirements, but for more upright riding the vizor does minimize the 'skid lid' look a little without getting in the way, and it can be taken off quickly and easily for more sporty positioned rides. There's plenty of venting, although the vents mainly allow for passive breeze rather than actively channeling air through, which is fine for the types of speed and effort this helmet assumes. Front vents are mesh covered to prevent insects from hitching a ride. Weight wise, it's pretty light for a mid-range non-performance orientated helmet.

The only area where I have a real issue with the Arella is in its fit. The design uses a one-size fits most theory, with an easy to use adjustment system inside the helmet that alters the size of the nylon cradle and webbing. I'm normally a medium sized helmet in most manufacturers' sizing, including female specific designs, but had to wear the Arella at full extension, where it was comfortable but on the snug side even then. For those with larger heads, the Arella would be a tight squeeze. However, the cradle system is VERY easy to adjust, as is the buckle, which also does not poke into the jawline or neck. It is a comfortable helmet to wear (sizing aside) and incredibly user friendly.

The styling probably won't appeal to all women, with the one we tested having an overtly feminized colour and pattern, but other less girly colours are available.
