On the road? how big is your solar panel that you will be taking with you? if it is few square feel it would be enough to charge a 14500 cell, maybe. not a 52V bike battery, and if you think you can ride and charge at the same time, it wont happen,

I increase the range of my ebike by pedaling with the motor. you add more lb you need more energy to move that extra weight,

o i like to peddle. mine does 28 mph when i peddle they say it will get 150 miles if i peddle i doubt thats true.i was hopeing when i changed tires from 20x3 to 20x2 id get more range due to less rolling resistance but not sure if i am geting more range at least the new tires are way cheaper. and easy to get at walmart

it will in theory, but i do not think it will matter much as far as miles in real world. your best bet is to carry a spare battery, cuz how many solar panels can you have open realistically on the go? it will probably all be lost in booster inverters,

i kind of figured long as i stay under 250 pounds with me and cargo ill be ok. becuae i see humans on bikes with tires about same size where the human has to be 300 pounds alone.

Peter Sripol demonstrated an ebike towing enough solar panels to power it. Do note this was three years ago.

This guy set up a solar panel to charge his ebike. The video is from 6 months ago.

Genasun has a solar charge controller which boost to 48V's for bikes and golf carts. I've seen some you tube videos charging bikes with them I believe.
They are MPPT controllers and are very dependable.

Dont use that thing on anything you care about.
I have seen too many short through.
Happened to a DARA menber recently.
When it failed the lifepo4 packs bms disconnected which put the full panel voltage on her new icom ic-7300.
Fortunately the damage was only a tvs and i repaired it easily and cheaply.
And any panel you can carry on the bike wont do much more than trickle charge your pack.
There are a million variants of that cheap and nasty controller on the market so dont be fooled into another.
