Surely many people remember what the brakes were on many bicycles of the Soviet era — they were foot brakes. While most brakes these days are cable or hydraulic brakes operated by handlebar levers, some bicycles still have a foot brake.
But what about e-bikes?
In some modern e-bikes like the Rayvolt X One, which I
As you know, the PAS-sensor of an e-bike detects the fact of pedaling. And if you pedal in the opposite direction, the signal from the PAS sensor will differ from the signal generated during normal pedaling.
Thus, the controller of the e-bike can determine if the pedals are pedaling in the right direction or in the opposite direction.
On the one hand, this provides safety — the controller will not turn on the engine when pedaling backward. Alternatively, this signal difference can be used to engage regenerative braking on reverse pedaling.
By itself, regenerative (or regenerative) braking is useful mostly for the purpose of
If we talk about light e-bicycles, in the overwhelming majority of cases a geared motor is used — whether it be a central motor or a wheel motor. But, as you know, recuperation
Thus, to increase the service life of brake pads by using recuperation, we are forced to use direct drive motors, which are 2-3 times heavier than geared motors, or even more. And by increasing the weight of the bike in this way, we somehow reduce the life of the brake pads, and we get a vicious circle.
And a natural question arises — which is better — to use a light electric bike with a gear motor and conventional brakes, or choose a heavier bike, but with a recuperation function. However, everyone decides for himself.
