However, this can be difficult when you’re out on the road unless you have your laptop with you.
The 50 series now comes with wifi capability allowing you to automatically download firmware updates with the special charging cable.
Just plug in the wifi charger and connect to a nearby wifi source such as your phone’s hotspot.
Mesh is an intercom software system that allows multiple riders to connect even when some riders are out of line of sight.
It’s not a system I use much, but for group rides it is very convenient and is a vital safety feature. (In fact, on one occasion, a rider behind me yelped and I knew straight away he had gone down even though I couldn’t see him.)
Critics say the Mesh software is unreliable, but Sena claim the flaws have been fixed.
I haven’t found any difficulties at all. In fact, there is less “crackling” interference from surrounding obstacles such as blind corners, trees, buildings, trucks, etc.
Sena says the intercom range s up to 2km in open terrain, which is about right by my tests.
I haven’t tested its full capacities with a “virtually limitless” number of riders in Open Mesh and 24 riders in Group Mesh intercom. (I don’t have that many friends!)
However, I have no reason to disbelieve Sena’s claims that Mesh extends range up to 8km (5miles) between a minimum of six riders.
