What is ERS ? Revolutionnary system for bikes ! |
Discover the ERS !New system of transmission of bicycles per belt and elliptic pulley, Every rider knows it, the first pedal turn is often the hardest, because two physical phenomena come to thwart his efforts. First, the friction exerted between the bicycle and the ground. Then, the inertia opposed to any body which wants to move it.
ERS is very simple, it is a “gearing system with a belt, elliptical pulley and two freewheels”, which enables 25% effort profit and a better fluidity of pedalling.  [ Cliquez sur l'image pour l'agrandir ]
You may have noted that the output of Easy Ride System is more homogeneous than the traditional system. Indeed, the resulting force is in phase with the moment of resistance, i.e; the provided power is even larger when resistance is important. Thus, when starting (with à°), ERS output is quite higher than a traditional system. 
| ERS is specially adapted to children when they learn how to ride a single speed bicycle whose weight is half their own weight. ERS provides them with a soft training with 25% effort profit and a better regularity of pedalling. |
Concretely, it means that, instead of providing a series of efforts with jolts, ERS makes it possible to start more easily and then simply ride your PAS bicycle providing a flexible and regular effort. Similar advantages can be applied on electric assistance bicycles. The PAS standard imposes a whole turn of the crank before starting the motor, that is to say, a high couple requiring a strong electric assistance as the weight to move is important. The combination of ERS and an effort sensor smoothes the couple, thus requires less assistance, leads to an improvement in comfort, thanks to a better variation of the request for electric output, and increases autonomy.
You want to know more about ERS system ? So go to the FAQs ! What is the ERS ? The ERS (Easy Wrinkles System) is a system of transmission of bicycles Per belt and elliptic pulley World brevet Gold Médaille to the contest Lépine 2005
Why ERS ? The chains is a transmission resource: dangerous, which obliges the manufacturers to pose entirely enveloping casings on the bicycles children misfit with the efforts which the users can provide.
A child of 14 kgs owes entrainer a bicycle of 7 kgs, An adult of 60 kgs owes entrainer a bicycle with electric assistance from 25 to 30 kgs, This operation requires very great efforts and often leads to a natural disinterest for the bicycle.
| With the ERS, you gain 25% of effort to starting, a fluidity of pédalage a silence of use a better safety (not of derailment of the chains, not of return of pedals in the legs) a cleanliness of use (not of grease) No maintenance (the belt does not require maintenance and has one lifespan equivalent to that of the bicycle) You want to take part in the aventure ? So, Contact ERS-cycles.com ! With the ERS, you will discover or rediscover the joys of the bicycle, with a pédalage without effort, fluid (without jolts).ERS, to make or remake bicycle with pleasure !Take your cycle, your bicycle, and pedal : that nothing more to see! |
