That's not my bike. My new ebike isn't fully built. My old ebike was possible to charge from my folding 30 watt array, it just took all day and defeated the purpose of bringing the bike out into nature since it spent more time charging than being ridden.

You need A LOT of solar to charge anything more demanding than a smartphone. At that point it becomes silly and burdensomely expensive. I would sooner just recharge an ebike from the car alternator.
