Re: My recumbent cargo bike

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...

Re: 120v mower and battery

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: My recumbent cargo bike

The hottest days are behind us for another year. Been pretty nice the last few weeks. Highs in the 80s F, lows in the 60s F. Haven't determined which specific hall wire it broken, in the external cable. https://endless-sphere.com/forums/viewtopic.php?f=2&t=101023 But it messes up infrequently enough...

Re: High performance & durability Cannondale Semi Recumbent

For those of you who are new to recumbents, I used to have a collection of recumbent magazines, which I donated to college engineering school. I just found a few issues of one of them online....Encycleopedia. https://issuu.com/search?q=Encycleopedia The same folks produced one called Bike Culture Qu...

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.

Which Shimano hub did you get 30K+ miles on?
It was a NOS, 1990's, Japanese made, Deore XT, Parallax.

Re: Halls effect sensors...the plague from hell

Been out of the loop for a bit. Just wanted to say I will definitely wiggle the hall cable, and replug the connector the next time it fails, to see if that fixes it.

Re: Halls effect sensors...the plague from hell

How have you determined the problem is 100% the hall sensors? No. Dogman Dan suggests intermittent hall problems are caused by faulty connections. I hope he is right. He has tons more experience with this stuff than I do, and that would be a lot easier to fix. I just did quick 27 mile ride, at 25.6...

Re: Halls effect sensors...the plague from hell

The Crown 4080 costs $800, plus shipping, is out of stock, and I'd have to rebuild the wheel. This motor has never been run outside its design specs for volts/amps/temperature.

Re: Halls effect sensors...the plague from hell

I have had intermittent hall sensor problems on thumb throttles as the halls go out I have never had a problem with the halls in my throttles. The throttle on my mid-drive started failing intermittently after a year. I determined there was a break in the line along the handlebar run. I assume it ha...

Re: Halls effect sensors...the plague from hell

The problem with testing is that the problem is intermittent. I had the problem the first time 31 miles into a 60 mile ride, for a few miles. The next ride it happened 7 miles into a 40 mile ride, again for a few miles. Then it didn't happen for hundreds of miles. The other day it happened three tim...

Intermittent halls problems are always going to be in the wiring to the motor.
Are you saying that there is no intermittent failure mode for a hall? That would be fantastic. It would mean the halls on both my bikes are actually OK, and the problem is in the wiring.

Halls effect sensors...the plague from hell

I have gone over 54K miles on my two electric assist bikes. One of the halls started acting up on my mid-drive MAC bike at 8K miles. At 9K it stopped working all together. I replaced the cheap sensored controller with a cheap sensorless, and rode another 21K miles. It sort of worked, but was never a...

Re: Poor Man's RV

But I've heard recumbents aren't as stable at low speeds. That's one area I've read as a negative to them, and why I feel they would be better on long rides with few stops, and worse in town with frequent stops. I will never forget a charity ride I was on, back in the 1990's. A guy on a dropbar roa...

I'm sure there's a good reason there aren't any recumbent MTB or racing bikes(though that would be interesting to see, and I'd watch the video).

Re: Warren's 350 MAC mid-drive (finally) recumbent

After 30,135 miles, the Shimano freehub froze up. The rear derailleur didn't like fixie mode and wrapped up the derailleur, and tossed the chain into the spokes. My otherwise perfect rear wheel was destroyed. I have been going back and forth about converting it to a left side mid-drive, with a Grin ...
