So I have a weird, crazy Trike concept, and having some trouble finding parts which may work. FYI this would be a build for Burning Man, so thoughts are based on having LOTS of cushion for when I/friend/someone else does something stupid/crazy.
My initial concept is based off of the Lode Runner plans, but scaled up somewhat with a mesh seat. For the scaling up, possibly wider, but definitely a good bit longer cargo area, and was going to use a jackshaft for pedal and electric motor would connect to. The cargo area would be built up with side doors, and some kind of seat on top (not sure forward or rear facing). Planning on the corners and cross would be welded steel, at least 1/2" square tube so should be plenty strong for significant weight of a person (or two?) on it. I realize this is a lot of weight to move by pedal power, but as long as I can get it moving OK, I won't be using the pedals most of the time, it'll be
Also planning for it to be able to be at least partially disassembled for storage. The rear cargo can be removed and knocked down semi-flat, the wheels and ideally rear shaft and jack shaft can all be removed, and possibly modify the design so that the center will be bolted together, and so can be taken apart so it fits into a somewhat smaller area.
For the drive-train, pedal power (meets the "legal" definition of not needing Department of Mutant Vehicle licensing), and a Cyclone 2-3KW motor (built in freewheel sproket). The jackshaft would then connect to the rear wheels via a single chain or possibly belt. However, the rear I want to be a differential so power both wheels. I have found the smagaga differentials and was originally going to build on heavy duty bicycle/tricycle parts, however I'm starting to get the sense with my desire for the rear cargo area to be built up and a person riding on it, my search for wheels (specifically wheels that can be bolted on via a hub attached to the shafts) leads me more towards golf cart or small car wheels, in order to be sure they'll withstand the weight, and not get bogged down easily in big dust piles.
It's not hard to find shaft driven rear differentials of various kinds. Golf cart, lawn mower, ATV, etc. I did find http://www.cyclexchange.net/Honda Trike Page.htm which is big Trike style, which would be awesome...except the price. $1,449.95 is a bit more than I'm willing to spend on it, although I do realize I'm not going to be spending $50, but I do want to try and keep costs down somewhat.
I also found https://chaindrivediff.co.uk/about/chain-drive-differentials/, although I question if they can do something in the price range I'd be looking at.
Anyone have any other thoughts on doing a differential to power both rear wheels? Or converting shaft driven differential to chain/belt? I've seen someone having the jackshaft have a differential type on it, and then 1 chain on each side going back to separate rear shafts.
I've also found these rickshaw motor + differential, and just go ahead and go ahead and register as a Mutant Vehicle, cut out the pedals entirely, and keep the basic frame concept intact. Do it as more of a rickshaw, but obviously a rather custom type.
As a side, for power looking at using perhaps 2 of https://greentecauto.com/hybrid-battery/repurposed-batteries/20ah-lto-titanate-li-ion-scib or 8 of https://greentecauto.com/hybrid-battery/nissan/nissan-leaf-battery-module to give me >60v nominal, and plenty of power. I'm also NOT going to be going very fast, ~5mph if going as a Mutant Vehicle, 5-10mph if going as a "pedal" electric trike. And will have a generator back at camp, or if as a mutant vehicle probably having provisions for a small 1500-2000W inverter generator onboard that I'll run as needed. Probably 2-3 hours a night, and then fully charge it up during the day at some point in time. I'll have to get a balancing BMS with either of those however, but that's doable. Plus some hefty DC-DC buck to run all the lighting
