Re: Sur-Ron - New Mid drive Bike

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.

Re: Nissan Leaf Modules 58 aH

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 ...

To show this in a direct comparison, the Fraunhofer team used 250W commercial pedelec motors.

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...

Re: No future for charging networks ?

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 ...

Re: Thoughts on cargo bikes

Recumbants sound very nice. I am nervous about using them in MA city traffic though. Do cars have trouble seeing riders so low to the ground? My recumbent cargo bike is not low to the ground. Look at that picture again. When I ride along side of folks on uprights, my eyes are higher than theirs. In...

Re: No future for charging networks ?

When I travel from here to Florida I can get in my car in the morning and drive the 1050 miles straight through in about 14 hours, including 2 fuel stops. With a Tesla that would simply be impossible. You'd need at least 4 extra hours to charge which pretty much means another day. To me that is imp...

Re: Thoughts on cargo bikes

I'm the old fart with the recumbent cargo bike. 70 miles is just a warm-up ride. For the first decade, it hauled me, a 150 pound wife, and 50 pounds of luggage just fine. That was strictly human power that had us pedaling a 22/34...16 gear inch at 90 rpm and 4 mph up mountains. I wouldn't suggest a ...

On the 15th, I attended a clean energy event, at the Pavilion, on the walking mall in Charlottesville. I have gone to several of these each of the last two years in the Bolt. But this is the first one that I figured I could ride to, spend 3-4 hours talking EVs, and still ride home before dark. I jus...

Yeah. Not the right location for this. But it is interesting that a few years ago knowledgeable folks on here said that 80 volt was the limit for consumer power transistors.

Re: High performance & durability Cannondale Semi Recumbent

The way to have a 2 ( or even 3 wheel recumbent ) is to make the frame on both sides of you , where you sit down inside the frame for lower center of gravity , the ability to use larger wheels , and to have a more upright sitting position while still aerodynamic http://rohorn.blogspot.com/2006/11/m...

I'm quite amazed that you can modify a motorcycle that much and get away with it in the UK. Hats off!
It isn't modified. It is a complete scratch built bike.
