Or you could lace the dyno hub into a 26" wheel for the Dunelt. Yes the lights will work with a bottle generator, however you will need to swap the bulbs out for a higher wattage. The GH6 hub dyno puts out about 1.8 watts a typical bottle generator about 3 watts. Need a 2.4watt head light bulb and a .6 watt tail light bulb.
