DEMING – A record holder in the Guinness Book of World Records has set off on a new quest through the United States in hopes of encouraging others to learn more about solar power and help save the planet. Sushil Reddy held the world’s record for the longest journey on an e-bike (electric-powered bicycle).

Back in 2016, Reddy and a group of students from the Indian Institute of Technology-Bombay embarked on a trip on e-bikes that covered nine Indian states. Seventy-nine days later and more the 7,000kms, Sushil and his crew set a new world record for the longest journey on a motorized bike. Reddy equipped his e-bike with solar panels that allowed him to cover extensive stretches of road without recharging and less manpower.

A veteran of long journeys, Reddy also travelled through three European countries and a part of the United States west coast on a solar-powered e-bike. The total solar-powered bike adventures covered 11,811kms in 139 days.

Reddy graduated with a degree in engineering from IIT-B and used his field of study in renewable energy resources to build the harness for solar panels that would power and trail behind his e-bike. The constant surge of solar power helped cut Reddy’s manpower by 50 percent.

His visits through the U.S. includes educating people on the benefits of solar energy and how it ties into clean energy and ultimately helping to save the planet.

Joining Reddy on his U.S. adventure is Luis Fourzan. “Me and my co-rider, Luis, are currently doing a 6,000-plus mile journey as a cause to raise awareness on solar power and e-bikes,” Reddy told the Headlight during a stop in Deming, NM on Dec. 16th this past weekend. “We reached El Paso after 125 days and 5,500-plus miles of riding.”

Reddy and Fourzan began their journey in Winston-Salem, North Carolina and expect to finish in Houston.

The personal drive for Reddy’s adventures stem from his realization that people in his native country knew little about the resources available with solar power. Through seminars and workshop along his travels, Reddy and Fourzan hope to better educate and bring options to the people they encounter along their journey.

Reddy has billed the U.S. trip as the “SunPedal Ride.” Along with Fourzan, the goal is 6,000 miles over 132 days.

Fourzan says that solar power is a source of energy that has many uses for households. The duo continues to collect information along the journey on how the states utilize solar energy. They share their knowledge with communities along the way.

“The sun is one of the resources that we will have forever, we can harness it across the planet,” says Fourzan.

I didn't see any Info at all on how much energy was contributed from solar on those 6000 miles. Isn't that what really matters?

He has 6 square feet of solar, nominally about 90 watts, but I'll derate to 30 watts at the battery to account for clouds, the panels pointed straight up, and conversion losses. Give it 5 hours in the daylight and that's 150 watt-hour, At 15 wh/mile, that's 10 miles a day from solar. They're averaging 44 miles a day. Not bad. This commercial cargo bike with 6x-8x the panel area claims 60 miles a day.

My solar ebike teardrop design. Top and sides will have approximately 200 watts of thin film solar. I am estimating 30 miles a day and using PAS 1 only for hills. Regenerative motor ebike will recapture some power on downhills. Solar battery storage will also be used to run low watt lights and laptop in the camper. LIFPO4 Power station used for storage capacity.

I recharge my 48 volt 20Ah battery from my 400 watt solar power system and it takes about 6 hours of good sunshine.
