here is the stat of it's daily production during the race and the distance it traveled.
Usually between 2000 and 3000 wH per day.
I will chose a bike with 3 wheels for stability.

Bingo. Shade of one won't effect the output of others. Worst option for shade is panels wired in series into one charge controller. 2nd worst, Two wired in parallel into 1 charge controller. Best option, separate charge controller for each panel.Solar Queen

Thank you.
I am learning so much here. I am very happy. I am still have to think about total weight. Each one weight 290 gr (0.64 pound). Maybe two would be good.
I will wait until I have an idea of all the weight I add then decide if I go with 2 or 4.

Usually e-bike are limited at 32 km/hr but not overthrew it seem because he chose his different component for a speed around 42 km/hr (not sure, I have bad memory
he says it was to maximize power transfert.
which is surprising to me because my current ebike goes far at 17 km/hr but not at 32. I have a friend how has an ebike with motor on the pedal axe (not sure how to say that in English) so by changing gear you can go faster. I went to 50 km/hr but battery was draining very fast at that speed.

Thank you. Reason I asked: Referring to the photo, at those speeds, the wind shield that's shown might help keep bugs from impacting the rider's junk, but given the rest of the vehicle's configuration, it won't do much to increase range by how much it might reduce flow induced resistance to the atmosphere. Might even reduce sweat evap. and thus raise body temp. some. Just sayin'.
per mile goes up as the square, because you get there faster. Bruce RoeComment

The racer used this tool to select his motor
Our ebike motor simulator allows you to easily simulate the different performance characteristics of different ebike setups - with a wide selection of hub motors modeled, and the ability to add custom batteries and controllers and set a wide variety of vehicle parameters you'll be able to see how factors such as throttle level, bike weight, hill grade and many more directly affect the performance of an ebike. You can even compare two different setups at a glance and at higher power levels and hill grades you'll even get an estimation of how long it would take the motor to overheat!

I have 2 bike. One with 360 Wh battery (Bike A) and one with 780 Wh (Bike B) every Saturday I go to the same place at 30 km from home,
With both bike I can reach the destination at 30 km/h and both are almost empty (by calculating charging time) even if B has twice the battery size.
At 17 km/h Bike A does not go that much further but bike B will go for almost 80 km.

gaps between, and move that shadowing support to the underside (see a massage table). Bruce RoeComment

I'm not sure I'd feel too safe on a road w/other vehicle traffic and/or if there was any wind blowing, particularly if that wind was variable and had any gust factor to it. Passing big rigs come to mind as well. Not all wind vectors are horizontal.Comment

I would stay off the roads that have big rigs and speed limits exceeding 45mph. Less chance of getting run over or blown away from the side draft.Comment
