I just went out and weighed my trike. What a fatty! It weighed in at 104.4 pounds! The frame is 1" square steel tube and besides the motor it has a 12v motorcycle battery, tools and lights.
Gearnut, place a bathroom scale next to your bike's stand. Lift your bike off the ground, then step onto the scale. Note the combined weight; now weigh yourself and subtract from combined weight. That's your bike weight.
"The Dragon Lady" weighed 140lbs. with electric hub and 80lbs of batteries.
When I replaced the electric drive with twin Mitsubishi 2.2hp engines, it weighed 105lbs.
My Diamondback bike with Scooterguy mount and Tanaka 47R engine weighs 55lbs.
My "Project 29" with GP460 engine should weigh 45lbs.
