Sena has expanded its range of communication solutions for cyclists with several new products. The technology specialist is presenting various systems based on Bluetooth and Mesh Intercom technology, which are designed to enable cyclists to communicate safely and networked while riding.
The highlight of the portfolio is the new BiKom 20, an ultra-lightweight communication device specially developed for cyclists. Sena also offers the Helmets S1 and U1 solutions with a fully integrated communication system. The products are aimed at different target groups - from ambitious racing cyclists and mountain bikers to commuters and leisure cyclists.
According to the manufacturer, the communication systems are particularly useful in challenging terrain when mountain biking, on family bike tours in road traffic, during group training or when travelling by bike. The technology should not only offer comfort, but also contribute to greater safety, better orientation and a stronger sense of community. Team Picnic PostNL is one of the professional athletes already using the BiKom 20.
Sena BiKom 20: Ultralight communication system with flexible mounting
At 20 grams, the new BiKom 20 is a particularly lightweight communication solution that is characterised by its compact and minimalist design. The system has an open-ear headset design that leaves the ears free so as not to restrict the driver's perception of their surroundings. According to the manufacturer, this should ensure maximum safety.
The attachment of the BiKom 20 is flexible: It can be attached to the strap of almost any helmet with a strap width of up to 18 millimetres or alternatively to a cap or other equipment using a clip supplied. Technically, the BiKom 20 offers Mesh Intercom 3.0 technology with a range of up to 800 metres for direct communication between users.
According to the manufacturer, an almost unlimited number of users can connect in Open Mesh mode, with six selectable channels to ensure interference-free group communication. In addition, the Bluetooth function enables pairing with a smartphone for hands-free calls, navigation and app use without additional accessories. The Advanced Noise Control technology is designed to filter out wind and ambient noise, while the HD intercom system with foldable microphone can be muted if required.
Sena S1 bike helmet: Integrated communication system for road and gravel bikers
The Sena S1 is a 300 gram bike helmet with an integrated communication system that has been specially developed for road and gravel bike riders. According to the manufacturer, the fully integrated mesh intercom system connects an almost unlimited number of users on nine different channels. The range is up to 1,200 metres, while the talk time is specified as up to 12 hours. As with the BiKom 20, Advanced Noise Control technology is also used here, which is designed to filter out disruptive wind and ambient noise.
A special safety feature of the Sena S1 is the integrated adaptive LED rear light with acceleration sensor. This warns following road users when speed is reduced by lighting up more brightly. The system works in all modes and is designed to improve visibility in road traffic. The S1 is aimed at ambitious cyclists who want to stay connected during training rides, group rides or solo tours. The helmet combines communication and safety functions with a sporty design and, according to the manufacturer, should offer a high level of comfort.
Sena U1 bike helmet: Smart for everyday urban cycling
The Sena U1 is a 400 gram helmet that is specially designed for commuters and e-bike riders. It has a fully integrated intercom system with a range of up to 600 metres and offers nine channels for communicating with other users. The talk time is specified as up to 11 hours. According to the manufacturer, a dual antenna system ensures a stable connection even in densely built-up areas. Like the other Sena products, the U1 can also be connected to a smartphone via Bluetooth, allowing phone calls, navigation or music playback directly via the integrated speakers.
These are positioned so that they sit open over the ear, allowing traffic noise to still be heard - an important aspect for road safety. The Advanced Noise Control technology is also designed to ensure clear HD audio quality in the U1 by filtering out disruptive wind and ambient noise. The helmet is available in two sizes (M and L) and can be fitted with either a transparent grey or transparent orange visor.
Mesh technology for seamless communication
The mesh technology used by SENA is based on Bluetooth and enables dynamic communication between multiple devices. The system is designed to provide a seamless, reliable and self-healing connection. According to the manufacturer, a virtually unlimited number of participants can connect and communicate on a total of nine channels. The direct range is specified as up to 900 metres, with several participants it can be increased to a maximum of 1200 metres. An important aspect of the SENA systems is that, unlike conventional communication solutions, they work openly via loudspeakers and without headphones.
This is intended to maintain a 360-degree sound perception of the surroundings, which should increase safety. Communication between the devices works independently of the smartphone, so no mobile phone, provider or data volume is required. The HD intercom system is designed to ensure the best sound quality, while the Advanced Noise Control technology suppresses ambient noise such as strong wind and ensures clear and distinct transmission to the other party. As an option, the products can also be paired with a smartphone and used for navigation or phone calls.
