@GrahamPaul : yes
@Kiwi in Wales this csv file is interesting, and it would be even better to have at the same time the mechanical power at the whell with a powertap hub.
Power on ebike is software limited, to comply with the 250W regulation.
For this demonstration, i will consider long term continuous use at 250W, as in the regulations.
(the regulation allows for short periods of time, to exeed 250W. I have seen numbers around 750W !)
An electrical motor have a...
The interest of the notion of power is that it's value is keeped through gearing (when the transmission have good efficiency).
Your gearing, and the gearing of the motor have negligible effect, and the power used is the force pushing you uphill × your linear velocity.
I suggest you look for this...
It does.
Power is torque × velocity.
Imagine you tune your bike to allow it to have assistance at 32km/h rather than 25km/h (by using something to fool the stock speed sensor). Comparing the 2 configurations, the motor will put out the same torque at both speed. But the deristrected bike will...
This is wrong concerning the power.
Power is velocity × speed, so at 0 rpm the power is null.
On a synchronous motor like used on the bikes, you get maximum torque when the magnetic field of the stator is perpendicular to the one of the rotor. This is essally done with modern ESC.
Yes you can do that. It s just the exact dame principle as anti squat for a rear suspension.
But theres more, with a linkage susp, you can also have a rear path for the front whell to get out of the way for square hits.
Also you can manipulate it to have a constant trail, rather than a...
It's not a Lauf.
It's a motion, a French brand. The spring is a pulled bent strut, very interesting with it s low histeresis and progressive nature.
There is also an hydraulic damper.
