Powerpod on e-bike

Post by clamic »

Hi,
Has anybody tried the powerpod on an e-bike?Could this even work or is this senseless?

Thanks

I suppose if you want to see how much power the electric motor has - then it would make sense :D

PP measures the total power produced both by the motor and the cyclist.

We have developed a completely new eBike torque sensor, called VTorque, based on this principle.

That sounds cool - plenty of new users to gather up!

Will you distribute the Vtorque eventually?

eBikes have two sources of forward power: the pedals, and the motor.

VTorque works in combination with the eBike's controller (the electronic box that provides energy to the motor). VTorque tells the controller how hard the cyclist is pedaling, so that the motor output can be adjusted dynamically to provide a smooth eBike experience.

Of course, we have patents... :-)

We are working with some of the top eBike companies in the world to implement VTorque. It won't be sold as a stand-alone product, but rather as part of their eBikes.

Any news on which Ebike companies implement VTorque.Are there any other developments how to get realistic power data on an Ebike?
Thanks clamic

Here is a ride I did just this morning. I'm using a PowerPod (Newton) that records the total power produced by the cyclist and motor, and the power applied to the pedals (Assioma).

VTorque is controlling the motor, and in this test the idea is to keep the cyclist pedaling at roughly a constant 100W, independent of bike speed, wind conditions, or hills. VTorque tells the motor how hard it must work to maintain the 100W set point goal.

In the graph, the total power (white, TOP GRAPH) produced by the cyclist and motor is as much as 500W+. Highest power happens on a hill (slope goes + and -).

The green line in the top-most graph shows the amount of power I'm applying to the pedals; it hovers around the 100W mark. "pedal DFPM"

The bottom graph shows the difference between total power (cyclist + motor), and cyclist power; this difference is the motor power. As you can see, the motor power varies all over the place, as it should, in order to keep the cyclist pedaling with roughly 100W of effort, irrespective of changing wind, slope, and speed conditions.

So, with VTorque, riding an eBike is like riding a normal bike, but just a lot easier!!

Stand by...we will be demoing VTorque at Eurobike 2022 :-)
