Here is my Dyno-Glide Electric Cruiser:

Crystalyte 5304 Front Hub Motor laced to 700c rim in front, 26" rim in back - 72 Volts of SLA's: 6 12 volt 12 ah... Kona P2 rigid fork (had to weld it to a 1" steerer tube to fit this cruiser frame) - all electronics are in the rear audio rack, along with the batteries. Center of Gravity is extremely low, due to the rack rails welded to the frame to support the batteries right below the rear axle.
