Abstract

The invention relates to a speed regulator of a bicycle, which speed regulator is in the rear hub or the pedal centre of the bicycle, which includes one or more hydraulic pumps (6) which is rotated by a rear pinion (11) or by the pedals, which hydraulic pump (6) rotates one or more hydraulic motors (7), which hydraulic motor / hydraulic motors (7) rotates / rotate the rear wheel of the bicycle. According to the invention, the rotation speed of the hydraulic pump (6) can be steplessly changed when the rear pinion 11 or the pedals rotate at constant speed.

Description

technical field [0001] The invention relates to a speed regulator according to the preamble of claim 1 attached hereto. Background technique [0002] At present, the transmission of bicycles has been implemented as a so-called hub gear transmission, or by a combination of front and rear derailleurs. [0003] In hub gearing, the transmission is built into the rear hub by using various gear structures. Then, the number of gears is usually 2-7. [0004] In a front-rear derailleur combination, the bicycle includes a separate front derailleur positioned in connection with the pedals, and a rear derailleur in the rear hub. Then the front detachment uses 1-3 gears, and the number of gears at the rear detachment is usually 6-10. This provides up to 30 speeds whose gear ratios can, and usually will, overlap. The job of the front and rear shifters is to shift the chain from one gear to the other. [0005] The main problem with the currently known transmissions is that the number ...
