Specific features of DELTA
If a Hector Delta is used as a bicycle or assisted bicycle, it is covered by the "moped" legislation, which is the only legal way to ride at more than 25 Km/h
in Europe (Germany excepted). (The limit of 25 Km/h for Ebike is judged really too slow by the clients targetted by Hector Delta.)
The question of the maximum speed of a Delta has no more signification than the maximum speed of a bicycle, this is why we speak of the cruising speed, which is the speed you can maintain indefinitely (see the technical specifications).
How a Delta ridden ?
When you get on a Delta you are on a perfectly classic bicycle (no extra fiction). It moves into assisted mode when you start the motor and activate the accelerator.. This can be done when moving (easy reliable starting of the 4 stroke motor). So much so that the motor can be stopped whenever its not
needed (on a descent or when moving slowly).
In contrast to an Ebike a Delta hybridization may need a brief training lesson, between 1 to 10 Km of experience, depending on the person. The process can be summarised as a manipulation of the accelerator which determines the force added to the pedals that is already supplied by one's legs via the pedals and the classical gear change.
But in our case, the gears change the speed until the force needed at the pedalier is equal to a sum of the engine force plus the biker force (whatever the proportions).
Before a trial, nobody imagines what will be the consequence of this. It means that whatever the slope, there is always a gear, with which your own pedaling power is exactly what you wanted, even if you want to pedal hard, very lightly, fast or slowly. And contrary to what most people think, it changes nothing on the regime of the engine, which stays in any case at its best efficiency regime.
“All the pleasure of cycling, without the suffering” as has summarized the mannequin in the pictures.
Note : The constant torque transmitted to the back wheel (variable 0 to 10Kgm), gives such an exceptional grip off road, that we have been obliged to increase the length of the bike to keep the front wheel on the ground (on extreme slopes). And this surprising characteristic attracts even the Army.
