A bike headlamp is is powered by a generator that rubs against the wheel. Is the bike harder to petal when the generator is lighting the lamp? Why?

I think it has something to do with conservation of energy. Help explain please.

I don’t think it makes a difference. the radius of the wheel has not been changed, the peddling is still the same based on road conditions and terrain. It’s is the preferred lighting method for cyclists/or pros/amateurs. They certainly don’t want anything to slow them down.
Open the link and maybe there is something I missed.
(The narrow flanges reduce air resistance and the hub has lower drag than the regular SON28.)

looking for info on Frog bicycle pedals.How well do they work when used on a recumbent bike?

Here is some info on the frog pedals. I don’t know anybody off hand that uses them but I do know a couple people that use either SPD or Look pedals on their recumbents. They shouldn’t be much different than those two in terms of getting unclipped.
