There is a golden ratio for vehicular efficiency, that is, vehicle weight / cargo weight. A typical truck that weighs 8000 lbs., and often carries 2000 lbs. of cargo around town, comes in at “4”. That’s obese! One wants to get the ratio below “1”, where the cargo weighs MORE than the vehicle. Who’s the king of the golden ratio? the cargo bicycle, the cargo trike, or maybe the electric cargo trike??
Honoring the ‘golden ratio’, we can achieve high levels of efficiency. The Truck Trike is coming in around 215 lbs. That’s just where we wanted to be, in the 200 – 250 range. And there’s the ambitious cargo load – 800 lbs. Then there’s the rider’s weight, and batteries. If we include the batteries in the vehicular weight, and the rider in the overall payload, we could easily see 250 / 1000. That’s 1/4 or .25 Excellent.
Bringing in electric assist allows the rider to move these heavy loads at a reasonable pace. Using dual electric drive motors, with the right gearing, allows us to power total vehicle weight that can top 1,000 pounds – yeah, that’s a 1/2 ton!
So, the flip side of the power coin, is stopping all this mass. We have spec’d some new motorcycle/scooter level hydraulic disc brakes on the rear, and I am presently working on the custom hardware to mount these components.
