So far I have the only ones that anyone knows of.

By the way the four 12 volt Evercel MB-40 batteries are rated at 33 Ah.
Hi Randy,
Well, here's my prediction as to how many AH you'll need to conquer that 10,000
ft mountain. Firstly, some of the key numbers that went into the simulation
program :-
Gross mass : 134kg
Chain reduction: 10:1
Course distance: 59km
Altitude gain: 3030m
Battery: 48 volts
I have broken the climb into 4 sections, of varying steepness, as below :-
15% grade for 6km @ 16km/hr needs 29.0A for 0.38hrs = 10.9AH
8% grade for 12km @ 18km/hr needs 16.3A for 0.67hrs = 10.9AH
4% grade for 29km @ 24km/hr needs 12.8A for 1.21hrs = 15.5AH
0% grade for 12km @ 30km/hr needs 5.4A for 0.39hrs = 2.1AH
Total time required is therefore 2.64 hours, for an average speed of 59/2.64 =
22.3 km/hr, or 14.0 mph.
Total AH required is 39.4 amp-hrs.
Collins computer program estimate was real close! I actually made it to the volcanos crator rim 1/8 mile from the summit in 2 hours and 40 minutes and the rested the batteries for almost 20 minutes while enjoying the view before proceeding to the top just after the first bicycle racers showed up, to cross finish line iwith my time of 3 hours and 3 minutes right behind them..

SUN CYCLES
Randy Draper, a longtime Napili, Maui resident and tour boat captain, has been experimenting with and inventing ways to harness solar energy for years. In the 1980’s Draper outfitted his house with solar panels and a small windmill; he hasn’t paid an electric utility bill since. Realizing the potential of the sun’s energy, Draper continued experimenting, at one point crossing the ten miles of ocean between Maui and Lanai on a catamaran powered only by solar energy. It is only fitting that his most recent achievement was climbing the 37 miles to the top of 10,000 foot Mt. Haleakala, which means “house of the Sun,” on a solar powered bike. Haleakala boasts the steepest road in the world based on vertical climb over distance. Draper chose the annual “Cycle to the Sun” race to test his bike. After starting at the rear of the “human powered” pack, he reached the top of Haleakala in little over three hours, at an average speed of 12 miles per hour. Draper, whose vision is millions of clean, efficient, and affordable solar bikes being used as transportation worldwide, is in the process of pitching his technology to prospective manufacturers and investors.

If this is not a worlds record then tell me who has done better in a ev elevation climb.Who has even made a 6800 ft climb in a EV or on a electric bike? Possibably 2 worlds records here that are documented by a race staff and published. I also have Video documentation of these rides using a single set of batteries and a single charge that was done at my home from SOLAR Power only.. WITHOUT the use of lithium batteries.
