This bike is a work of art. Your craftsmanship is amazing.

Yes. I have been running parallel chargers since 2011. They need a diode in them to allow running in parallel, without one feeding into the other, but most apparently do. Did it with Chinese 5 amp chargers, and now with two Grin Satiators.

I've noticed that even with a rather low power (750W) mid-drive the smallest cogs (11t and 13t) wear out really quickly. If you don't need huge range in the cassette, it would be better to stick to bigger cogs. Other option is to buy a bunch of cheap 11t and 13t cogs and replace them as necessary r...

Trikes are most popular because most recumbent buyers are old farts who have lost their sense of balance, and can stop half way through a climb, and rest without falling off. Trikes are, and always will be, less efficient than a similar single track vehicle.

everything I saw from the flea bay links was Used (and likely worn?).. not New old stock.. and anything actually quality NOS costs a small fortune.. Yeah. Like I said, I bought a bunch back when this stuff was considered obsolete. Not a good as buying Bitcoin at $850 like my buddy, but I'm happy. lol

Yep I know that I can get shimano altus, but it's really inferior compared to XT to be honest with you.

I don't know what you see when you use the link I posted, but I see NOS (new old stock) 1990's XTR, etc.

You can look for NOS 8-9 speed derailleur, 8 speed shifter and cogs. That is all I run on my bikes, with SRAM 8 speed chain. I bought this stuff when it was just obsolete, before it became collectible. lol https://www.ebay.com/b/Shimano-Rear-Derailleurs-for-Mountain-Bike-8-Speed/177813/bn_5670514 ht...

I owned and rode an original 20/20 Rocket, a 26/26 converted original V-Rex, and rode this rowing 700c high racer 3,552 miles. Much of that was in the Blue Ridge mountains of Virginia. Rode down to Vesuvius, and back up. It is considered the steepest, hardest climb on the entire Trans America Bike R...

Are all these builds without freewheels on a motor and a chainring?
What is going on here?

I put 30K miles on a mid-drive with no freewheeling cranks. It is awesome.

Can I see your build please? 30K miles sound like a lot.

Sure. Click on the link under this post.

Mid drives are more fun and more capable, watt for watt. Hub motor drives are more likely to get you to work on time, and less likely to leave you walking. Totally agree. I put 30K on a 250-500 watt mid-drive. I ate one rear derailleur, one freehub, and lots of chains. My monster DD required 150 mm...

Yes thats how it is, and one more reason could be the BMS. Lets say the BMS does balance the pack at 4.10V with accuracy of 0.01V and then the pack get discharged to the end of the curve, that small difference from the beginning could increase to 0.10V then. Yup. Our 2017 Bolt, like most until half...

You all may be interested to hear what GM thinks about cell voltage variation. Back in 2017, when the Chevy Bolt came out, their service manual said that all cells in their 96s3p packs, from 4.16V down to 3.28 V, should be within 0.03 V. If any cells fell outside that value, the battery section cont...

Oh wow. You know, i called that company asking for parts a while back, and they were super friendly and fun to talk to. I'm happy to see they are pioneering still and not stagnating. .. it does look unnecessarily overbuilt and under-suspended. I feel this could be done much better.. it will have a ...

The Phoenix is a pretty standard LWB recumbent

This new variant will have a Bafang bottom bracket mount.

They say regen saves a ton of brake wear, so that is something we can look forward to.

I have 29K miles on my DD cargo bike. I am still on the original brake pads! The regen drops out below 12 mph, at which point I usually coast ten feet, and then tap the brakes to put my feet down.

Not sure what Craig is doing these days. He had a deer headbutt him off that scooter, riding in his cul-de-sac several years ago. The head trauma left him pretty beat up. His sons may be doing something. I know they ride Zeros now. They are friends of Terry Hershner

The Swiss Ecomobile has been around for an age: It was replaced a decade ago by the Monotracer, and is now built in the Czech Republic, and called the Monoracer. It is gorgeous, but still crazy expensive. https://www.peravescz.com/electric-version/ https://youtu.be/ARLl_QDXXng?list=PLVvzYlefm5vagxL...

Aha, a mid drive setup with a jack shaft. I was actually suggesting the motor drive the left side of the rear wheel, not through the gears. That way you can run more power without wrecking the bicycle freewheel, and still have regen. That rear swingarm looks long enough that you could mount it belo...

Small DD motors in big wheels are not a good idea. Here is what I have been considering to replace my 350 watt MAC mid-drive, which is down after 30K miles, with a failed freewheel in the planetary gearset. I have a new 559 mm (26") rear wheel with a rim brake compatible rim, and a disc compati...

Welcome aboard! Not nearly enough recumbents on here. I will be very interested in seeing your progress.

The oil embargo launched the rebirth of quite a few open, and enclosed, trikes. I used to have all the articles, books, journals, and periodicals from the 1970's through the early 2000s. I shipped it all off to UC San Diego Engineering School some years ago, I think it was. https://www.delo.si/asset...

This was BEFORE there was any Tadpoles...
First Tadpole or does anybody know of one before that?

There were tadpole trikes, an velomobiles in the mid 1970's.

Yeah. That was pretty interesting. I fooled with recumbent trikes back in the late 1980s. I had an idea for a lean steer trike, and had some guys in Indianapolis build one from my design for me. It was a real hoot to ride. I decided recumbent trikes were fun, but too low and wide for safety around c...
