I use this setup and it works pretty well.
My ebike is a 52v nominal Bafang BBSHD with a 12ah panasonic GA cell lithium battery.
My solar setup is http://www.powerfilmsolar.com/products/?fm167200_120w_foldable_solar_panel&show=product&productID=271514&productCategoryIDs=6578 for when I am stopped, + https://www.amazon.com/ALLPOWERS-Bendable-Flexible-SunPower-Irregular/dp/B013E07FNM mounted on top of a BOB ibex trailer, this charges the system while riding, and I rigged it so I can set up the powerfilm in parallel for a total of 220watts solar while stopped.
To step up to 56.8 volts (roughly 85% charge on the 52v nominal system) I got a https://genasun.com/products-store/mppt-solar-charge-controllers/golf-cart-solar-charge-boost-controllers/ GVB-8-Li-56.8V-WP
The system works pretty well, if you have time to burn to recharge. Its not as fast as charging from mains, but I have seen it pull 9 amps in full sun, which is pretty dang good for a sub 10 lb total system.
I see similar things on amazon too.

FYI for others considering solar. Flexible solar panels weigh much less and are simple to mount - heavy duty double sided 3M tape. They will fit on curved surfaces great.
