There are two main designs in my brain & may do both. I'll list what I've purchased but outcome may change. I'd like one yard/desert setup that has some solar recharge capability on-board. It will be heavy but have at least 3 wheels and one motor. I'm considering front & rear drives on a single bike. We'll see as I get into it.

Between the rain & sick family the past few months I've only been doodling designs & keep the new batteries topped once per month. I need a little yard truck but want an ebike too. I need to practice my poor wire welder skills to make the truck so a bike would be the quickest option. I see the new dual motor Fat ebike are around $5000 now! They're pretty much a cheap fat bike with a motor front & rear. My investment, including a bike, would be under $800. Go figure.
Hows your green ebike working,
Lurker?

my ecotric vortex works very well, thankyou, although i need to adjust the rear brake. i'ts been chilly out so i'm not riding much, maybe once a week. the Lady of The House is having balance problems and hasn't ridden her peacedove at all in the last year, which is part of why i'm looking at 3-wheelers, been casually thinking of finding a trike and putting a conversion kit on it. meanwhile, violet the peugeot languishes out by the (former) chicken coop  how about a trailer for the e-bike, would that do what you need?
looking forward to seeing this as it develops. |

So where do you go when bike parts aren't quite gonna work for certain unique requirements? A go cart & mini bike warehouse of course! Power transfer & steering in particular but just browsing parts ticks more creative options. This is one of 4 sites I'm scoping out. www.kartpartsdepot.com/ |

The first electric runner will be front wheel drive on either the new Argus or the Bullseye Gravity fat bike. Anticipating connection and/or longevity issues while rough riding in the desert, it makes sense to have a strong free hub in the back with a upper scale derailleur & shifting system in the event I'm forced to pedal my butt. Already have the new air suspension fat fork & headset ready to install. The etrike is still a go but installing a system on a 2 wheeler will be simpler for a first attempt.

It's probably worth noting here that this project is on the cheap. Relatively speaking anyway. We're talking $135 for the double shoulder fork, $55 for the hydraulic brakes & shimano rotors. The hub drive & battery were just under $200 each. Oh yeah and $245 for the bike. Call it $500 with incidentals not including the bike. Probably about $350 using a 36V 350 watt system instead of the 48V 1000-1500 watt I've standardized on. Just figured the extra horsepower would be needed for sand, washes & hills.
Now compared to the $3000-$4000 up to $6000 "bikes" mine won't be in the same quality arena. Some do have dual piston hydraulic brakes like $300 shimano XTs, 30Ah of batteries on board, 2000 watt motors, or both wheels have hub motors, and cables & lines routed inside the bike frame. Some are full suspension custom aluminum frames, full fenders, and everything is completely water & dust proof. At least on paper. Some of these @ 2000+ watts are really electric motorcycles capable of potentially running 50 MPH. That's not at all what I'm looking for.

looks like a really nice set-up!
i'll be interested to see if my positive attitude re e-bikes changes when i have to spend a couple of hundred to replace a worn-out battery. i've yet to run it down to zero, but i notice the charge indicator drops from 4 to 3 or even 2 pretty quick lately... |

Seems a little early for that to be happening. The claims of no battery memory & 500-800 charge cycles without degradation sure look good on paper. I've always been dubious about those numbers. Like the solar industry, real world data vs claimed specs seems to be around 70% of sales propaganda. The market is ready for another leap in battery tech for sure. stringing together dozens of little batteries to make these electric storage bricks is a flawed design that stuck. |

The fork was delivered today. Seems to have held air all the way from china. Guess I should bleed that commie air & replace it with good ol' Merican semi-scocialist-neo-freedom-post-covid, air. Also, found a little trick with the PCP airguns. A couple drops of high grade silicone oil in the air stream during inflation goes a long way toward seal & valve longevity. Supposed to have a few nice days in a row after tomorrow. Will lay out fork, wheels etc for some photos. Still having dubious brain patterns regarding which fat frame to use. The Gravity Bullseye definitely is not on the list but I can come up with good reasons to use the new aluminum frame Axiom or steel frame Dolomite. The Hitch (the red one with the high BMX handlebar) is aluminum but cant fit tires as large as the other two. Eh. Maybe staging all the parts will give me inspiration.  |

Why did you make that choice? That had been my thought most of the time since I bought the motors. But a high-ten steel frame will flex a bit & welds can be repaired if broken. Aluminum frames don't flex & breaks can't be repaired. Most steel frames are rated for riders well over 300 lbs where aluminum generally top out at 250 or so. This will be a damn heavy bike. When fully developed it may have 2 hub motors & 2 batteries, 2 controllers, water, tools, & me. The bike alone will be over 100 lbs. Now consider g-force in arroyos & large bumps & rocks etc. It won't be a street bike. Also, the weight difference between an aluminum & steel bike frame is negligible. In a 29er or big box fat bike you're looking at 2-3 lbs. A big deal for a devoted bike-anal gram counter, but not so much for this application. Yet the aluminum frames, in no particular order of import, take standard cartridge bottom brackets (hence more upgraded crank options), have replaceable derailleur hangers, don't rust, & more water bottle bosses that can be repurposed for batteries & controller boxes. As usual I'm probably overthinking this. It's what I do  |

because (i heard someone say this somewhere) "this will be a damn heavy bike", that's why. and if it doesn't work out, after a while you can move the expensive stuff over to the steel frame. at your age are you going to be jumping canyons, or is t a farm truck? go ahead, overthink, i usually do!

A bit warm. yes. Had to do another 2100 mile round trip on short notice. My back was/is in a real bad way & came home to a dead AC unit. Other than that its been just peachy! 
Great for some things. Vans are such a bitch to work on. But what car isn't anymore...
