As bicycles become an increasingly popular form of transportation in big cities,the number of accidents is also on the rise,often because riders can't focus their attention while trying to navigate with maps and directions from their smartphones.A new technology developed in Canada may make navigation simpler—and therefore safer.

In many cities around the world,including Montreal and Washington,D.C.,anyone with a credit card can go to a ride-share station and rent a bike.But knowing how to ride and riding on a busy street safely are two different things.

Public Bike System Company,which operates Montreal's bike-share system,says its riders needed a device that could make figuring out how to get to their destinations simpler and safer.

Smart Halo,developed by Montreal-based company CycleLabs,letsriders keep their smartphones in their pockets.

“By having Smart Halo on your bike you get very simple and clear instructions,”said Maxime Couturier of CycleLabs.

Fixed on the handlebars,Smart Halo connects wirelessly to the rider's smartphone,finding the simplest and safest route to the desired destination.

“When you don't really know the city,it's really great because it tells you where you can go,”said cyclist Emilie Bonnier.

Smart Halo,which costs$150,also has a built-in safety device that flashesred and sounds a loud alarm if someone tries to steal the bike.

Its developers hope to fix the device on all bike-share bicycles in Montreal,and hopefully on millions of bikes around the world.
