Bike Light Generator

Can I use two generators bike light (6 V each) to help recover energy to recharge the battery on my scooter.? Wheels provide energy and jet ribs so I would use hills and I'm looking for a full charge thats why I chose 6V less friction

You will need a rectifier and a regulator for a generator bike is AC. and you will get an energy of very poor quality because of difficulties to eliminate when you connect them together for a better turn on your scooter 24v.
