Mikael ran a test on the weekend to see how PodRide would do on some very steep hills. He has given me a big thumbs up. PodRide conquered a 25 degree incline (46.6% grade), which is quite steep indeed. The kind of steep that you have nightmares about.
Mikael went up the hill with the motor assist. He also tried to go up the same hill without the motor assist but was not able to do that.
To give you an idea of what that level of steepness looks like in real life, let’s take a look at a couple of streets in San Francisco.
Most people naturally describe steepness with an angle. However, road builders speak in grade, the ratio of vertical rise to horizontal run, expressed as a percentage. Angle and grade are not synonymous: for example, a slope that rises one foot per two feet of run is about 27 degrees from level, but has a grade of 50%.
Please Note: We are not recommending that you take on extremely steep hills with PodRide, as with such a steep hill there is a feeling like you might tip backwards. This was done as a test for us to understand the capabilities of PodRide and would be steeper than any recommendation that we might make.
