I think the best would be a motor mounted under the seat with a gates belt on a large sprocket on the rear wheel. That's what Warren was talking about on the first page of this thread too. The secret sauce is those sprockets that bolt onto a disk brake rear hub in place of the disk. It's definitely...

Warren, Have you had notification of a Factory recall from GM regarding a possible issue with the Bolt battery pack ? I understand GM are recalling many (all ?) Bolt’s for a pack replacement following some unexplained fires in the LG packs. Hyundai Kona EV’s ...also with LG supplied packs, are also...

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.
