Selle de vélo

A bicycle saddle, often called a seat, is one of three contact points on an upright bicycle, the others being the pedals and the handlebars. (A bicycle seat in the specific sense also supports the back.) The bicycle saddle has been known as such since the bicycle evolved from the draisine, a forerunner of the bicycle. It performs a similar role as a horse's saddle, not bearing all the weight of the rider as the other contact points also take some of the load. A bicycle saddle is commonly attached to the seatpost and the height of the saddle can usually be adjusted by the seatpost telescoping in and out of the seat tube.

cadre de vélo électrique

2017-10-31 Nouvelles No comments

A bicycle frame is the main component of a bicycle, onto which wheels and other components are fitted. The modern and most common frame design for an upright bicycle is based on the safety bicycle, and consists of two triangles: a main triangle and a paired rear triangle. This is known as the diamond frame.Frames are required to be strong, stiff and light, which they do by combining different materials and shapes. A frameset consists of the frame and front fork of a bicycle and sometimes includes the headset and seat post.Frame builders will often produce the frame and fork together as a paired set.

There are two distinct types of controllers designed to match either a brushed motor or brushless motor. Brushless motors are becoming more common as the cost of controllers continues to decrease. Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and…
