Those are cool for the bike, and I might think about getting some myself for that purpose.
But for their intended purpose? Wow, I wonder if they're selling these as environmentally friendly? Because they're almost certainly an environmental disaster. Rather than just a string of LEDs, you're getting a string of LEDs with a cruddy solar panel and probably NiCad batteries (they're really cheap and don't need charging circuitry). They'll get used one season, probably saving a total of about 15 cents of electricity per string, then put away. Next year the battery will be dead because you can't leave nickel-based rechargables to just sit in a box for a year. Then they'll get thrown away complete with toxic battery.
Work: the 8 hours that separates bike rides.
