They have different size on the website, but it really depends on how large your bicycle battery is. The largest one is 60W and ways 1.7kg. A small bicycle like that might have 300Wh or so. Since you probably just lay them on the ground and they are not 100% efficent anyway with charging you need 10 solar panels or so to charge your bicycle up within an hour.

If you want it for a cycle trip, then you are probably better of having a fixed panel on a trailer. That way you can charge during the trip and non flexible panels are much more efficent. You end up with something like these.
