The road is about 1/2 a mile long with a grade of about 16%. I weigh 175 lbs and the bike weighs about 35 lbs prior to being electrified.
Check out Mr. Bill's site for some great info.

The road is about 1/2 a mile long with a grade of about 16%. I weigh 175 lbs and the bike weighs about 35 lbs prior to being electrified. I'd go with the spoked wheel myself. The controller is claimed to have 26 amp max draw, so you could see this. https://www.ebikes.ca/tools/simulator.html?motor=L...

Re: Around the world on a solar ebike

Fabric tail fairing mock-up. What do we think? Is this worth pursuing? Over decades of riding, and lusting after higher speeds, I found that my average speed on a long day never got over 15 mph. At that power level, adding fairings didn't help. Maybe crossing Kansas into a head wind, but in the rol...

Re: Why no 240v off grid?

Watch Jack Rickard's EVTV. He sells 400 volt DC/240 volt AC off grid systems.

He is a bit hard to understand these days, as he is dying of lung cancer.

Re: Electrom1 Long Wheelbase Recumbent Light Electric Vehicle

Thanks for the new video. All the talk of endless electric SUVs coming soon, makes me depressed. This is the most hopeful thing I have seen since the pandemic started. Stay well, and all the best.

Re: Around the world on a solar ebike

There was lots of research done from about 1975 to 2005 on the aerodynamics of recumbents, by university engineering departments, and independent developers. They found that, as cowardlyduck suggests, an upright seating position acts as a parachute. Laying the seatback back reduces that effect. Also...

Re: Tesla battery day announcement

who wants a car battery to last 10-15+ years ? Lets see. My last car was a 1993 Nissan Sentra E. Paid $9K cash when new. It was 23 years old when I drove it to the junk yard. Got $150 for it at 328K miles. Our Bolt EV is now 3 years old and 33K miles. It will be our last car. We will give it to one...

Water works great too. Turn the forks to get the grip end pointing down. Gravity is your friend. Insert a small screwdriver under open end of the grip to get access. Use a syringe, squirt gun, or squeeze bulb to get water between the grip and bar. Massage the grip to work the water around. The grip ...

Re: Nissan Leaf Modules 58 aH

According to my CA, my pack ranged from 0.025-0.030 ohms impedance when first installed. It now ranges from 0.035-0.040 ohms.

If the OP's pack has been stored at moderate temperatures, and 30-70% charge, it should retain most of it original capacity.

I have the exact same pack on my cargo bike, from the same vendor. They came from a low mileage 2015 Leaf. Mine are 58.8 volt fully charged and balanced, down to 44.8 volts where I cut it off. My bike runs 32 mph at WOT at full, and still runs 25 mph at the end of charge. The average voltage for a r...

Re: Tesla charging problems ?

Typical dryer is 30A, and typical range is 50A (I've seen 30 and 40 amp circuits as well). Either way, Tesla's mobile adapter states it will pul up to 32A max. Hmm. Ours pulls 40A from our 50A outlet. Tesla makes two mobile adapters, one for the S and X, and one for the Model 3. The Model 3 Gen II ...

1153 mi round trip...central Virginia to Rochester and Ithaca NY

The first week of October looked good for our first trip to New York in the Bolt. Left at 8:15 am, and arrived home at 9:45 pm, a week later. The non-Tesla DC charging infrastructure is still a joke, but at least now the trip is doable, with luck. We drove Rt 15 mostly...no interstates. 1153.3 miles...

We just did an 1153 mile round trip to New York in the Bolt...Rochester, and Ithaca. We took two days up, and one back. The two days up was pleasant. We only did the one day back because we knew we would be sleeping in our own bed. Doing that in one day is my idea of torture. So, 575 miles one way ...

Re: Thoughts on cargo bikes

If you could redo your DD recumbent build, would you use leaf batteries again? After three and a half years this pack has gone from 2897 Wh on the first full discharge, to 2288 Wh today. Leaf cells are notorious for degradation. If money was no object, I'd go with two EM3ev 72 volt, 34 Ah packs in ...
