get dynamo, why use motor battery when you have small front wheel that spins like mad, @andymatthews runs TWO lights from his dynamo.
Isn't using a battery to power a dynamo a bit inefficient?
wait what? I am saying why take power out of battery for light when you can have super efficient dynamo with 20" wheel
