buy electric bike bar ends

2018-03-16 Жаңалықтар No comments

In cycling, bar ends are extensions typically fitted to the ends of straight handlebars.They extend away from the handlebars and allow the rider to vary the type of grip and posture that they use during a ride. They are especially effective when climbing out of the saddle, because they increase leverage. Bar ends can also improve comfort for the rider due to the neutral position of the hands (palms inward) which places marginally less stress upon the musculature,and by providing more than one place to rest hands on a long journey.

A bicycle handlebar or bicycle handlebars is the steering control for bicycles; it is the equivalent of a steering wheel for vehicles and vessels. Besides steering, handlebars also often support a portion of the rider's weight, depending on their riding position, and provide a convenient mounting place for brake levers, shift levers, cyclocomputers, bells, etc. Handlebars are attached to a bike's stem which in turn attaches to the fork.

Shifters are mounted on the down tube of the frame, stem, or various locations on the handlebars.

electric mountain bicycle lighting

2018-02-01 Жаңалықтар No comments

Bicycle lighting is illumination attached to bicycles whose purpose above all is, along with reflectors, to improve the visibility of the bicycle and its rider to other road users under circumstances of poor ambient illumination. A secondary purpose is to illuminate reflective materials such as cat's eyes and traffic signs. A third purpose may be to illuminate the roadway so that the rider can see the way ahead. Serving the latter purposes require much more luminous flux and thus more power. Many jurisdictions require one or more bicycle lights to be fitted to bicycles ridden at night — generally a white light in the front and a red…
