Second test of my new solar bike

Today, the wind conditions were more favourable than last Tuesday, however the Vered Sun of the early afternoon provided less energy. By adjusting the engine power to 100W, I drove at an average speed of 31.5 km/h on a 90 km course with 650 m of positive elevation.

First test of Solarduino Bike 3rd version

Yesterday I experimented with my new solar bike! It is made up of a classic bike and a motorised trailer. I built this new trailer in order to support 3 solar panels of 100Wc (I only had 2 last year).
My intention is to increase the length of my courses. With 2 panels last year, I had completed courses of a little more than 200 km. With 3 panels, I now hope to exceed 250km per day.

For this first 2-step test, I travelled a total of 129 km with 1080 m of elevation gain in 4h25. My average speed was close to 30 km/h.

Due to the sunshine conditions, I set the electrical assistance between 90W and 115W with short moments at 225W.
In quite unfavourable wind conditions (wind of 20/25 km/h with brutal gusts at 50 km/h), I was able to appreciate the good behaviour of the trailer, very stable in turns of the road.
