Recently, Ed Ward, a cycling enthusiast in London, invented a wearable bicycle light, the Commuter X4, to help motorists in night trains identify bicycles in front of them and determine distance and speed to avoid traffic accidents.
The Commuter X4 is an LED that can be carried on your body or backpack. It has four adjustable straps that can be tied to a 35-liter volume. LED lights have a waterproof function, a variety of flash patterns, can be used under harsh conditions. The device has a USB charging port that can be recharged for 15 hours on a single charge. Ed Ward said that the Commuter X4 is not easily blurred, has high brightness, is more flexible and conspicuous than traditional rear lights, and is safer to ride at night.
Commuter X4 won second place in the "British Inventors Award" at Gadget Show Live 2014. Currently, Ed Ward is developing a wearable bicycle light that can be placed on the front, rear, or helmet. The Commuter X4 has already started to raise funds on the crowdfunding platform Kickstarter for $65.
Someone may not clear that it would change the time, resulting in poor engine performance even damage to valves, if the teeth on the belt jump over the teeth of gear. So that`s why Tensioner Bearing exists. It keeps belt tension never be too low or too high.
The tensioner Bearing should be replaced when replacing the timing belt. And we are professional for the United States, Europe, Japan and other countries, to provide high quality and affordable tension bearing.
belt Idler Pulleys are provided with a series of radial reinforcing ribs to prevent deformation caused by the wedging action of the belt.
The Timing Belt Tensioner is used to keep tension on the timing belt. The timing belt is a rubber belt that runs over and through a series of pulleys and gears. Over time, due to age and heat, the belt will stretch out. As the belt stretches it can become loose, so the tensioner needs to adjust the belt as needed to keep it tight.
