Although more people are getting around by bike, cyclists remain the most vulnerable group of road users. Could a range of wearable technologies keep them safer?
In the UK, the number of people killed in cycling accidents is on the rise.
Most serious incidents involve another vehicle and commonly occur when the cyclist is travelling straight ahead and another vehicle turns into it, research suggests.
