I'm sure it's super dumb and worthless in reality but it's also kind of neat, at least I thought so when I saw that thing on TV as a child. I could imagine one as a streamlined recumbent bicycle that could haul rear end on flat ground maybe (because three wheels are an inferior number of wheels)

oh also, while we're on the topic of weird motorcycle space pods, let's not forget the LIT C1


In Neal Stephenson's sci-fi novel "the diamond age" vehicles using either half a lane or a full lane are mentioned, and full lane vehicles are treated as an expensive luxury by the author.

There was an attempt at a gyro stabilised two-wheeler thing in the 1960's. It had outriggers though:

Personally I like things that lean into corners because it feels good. I'm not alone in this but the only non-motorcycle corner leaning thing I ever see in traffic are these things:



I think their main attraction is that you can drive them with a regular car licence and go faster than a class 1 moped (45km/h).

I've never ever seen any of these:



I also strongly feel that three wheels is wrong and bad because wheels should always come in pairs unless it's a wheelbarrow. So pod bikes are cool I guess and I want to try one but not pay for one.

That's ingenious. It looks super sketchy at first I see no reason that wouldn't work fine if I understand it correctly from those pictures.
I assume it's just an adapter that fits on a normal luggage rack? I had to look up local legality and as I understand it it's fine as long as the rearmost part of the protruding load is clearly marked with a little flag or something and total vehicle length is less than 24 meters. Lol. If I loaded my rear heavy commuter e-bike on my little honda like that it would probably become a wheelie machine, but with an added wheelie bar so that's no problem :)

For riding on bike paths and in the city, the only suspension you need is fattish tires (like 27.5x3, 700x50, even 26x2.4 ok) on an e-bike. Fight me.

I assume most of these home brew e bicycle people are actually trying to make an e-moped, not a e-bicycle. Meaning they are not interested in actually pedaling and they want to go faster than 20 mph while not pedaling. Which is a different goal, with different forces involved and different spec requirements for various safety bits like the brakes.

I homebrewed my current commuter ebike, mainly because anything store bought here is 250w and more importantly capped at 25 km/h. So I bought a 500W system and slapped on a sound old-ish 29:er I got for a fair price - anything store bought of comparable quality would have been at least twice the cost. I chose the wheel size primarily for the best tire selection (I ride on snow and ice a lot so tires are important) but I admit I like that it looks cool. I mostly ride with an assist limit which is pretty drat close 20 mph but I admit I'll pull out the stops sometimes when nobody's watching and I can go north of 40 km/h. I do pedal all the time, pretty hard when homeward bound since sweating is OK at that point. Pedalling is fun and I sure as poo poo need the exercise. I like and appreciate my squishy fork which lets me go faster and gently caress up more with less drama but it's a fair bit of maintenance and I wouldn't ever call it "necessary". If I were to build or buy or build another bike for the same purpose I'd go more for ruggedness/low maintenance and less for fun/performance. Winters here are really harsh on equipment what with salt water all over the bike paths. Nothing that spins or slides lasts long and anything that can corrode will.

Got a pic? That sounds rad. Do you do spiky tires in the winter?

I do, it is pretty great (when it's not broken) and I do.



I probably put 7000 km on the thing or so last year and things are bound to break so I shouldn't complain. Right now it needs new calipers since they're both leaking mineral oil onto discs and pads which isn't great for safety. Also really noisy. I have a pair sitting in a cardboard box on my workbench RN so it should be fine again shortly.

In a city, an e-bike is vastly more useful and handy, and possibly even more fun (if easier to steal). It's just if you ever want to leave that their usefulness falls off a cliff.

The exception to this is if you live somewhere with a functional train system (or even buses in some countries) that lets you bring bicycles onboard. I can bring an e-bike on the commuter trains outside rush hour for example, but I can't bring a motorcycle. There's a place I go on the regular that's 80km away which is a literal pain in the rear end on a bicycle and pushing the range on most e-bikes but the train/bike combo means it's only 10km in the saddle. Foldable scooters and all the other weird electric personal transportation devices are allowed on city buses, trams and subway here, which is the only reason I'd consider getting something like that if my daily travel habits included those.

man I'm super intrigued about that type of bike. Here they're sold as street legal mopeds and nerfed to 45km/h, but un-nerfing them seems trivial. Not sure if they can be registered here as an A1 class motorcycle though.
Like you said, it's probably possible to ride them where a combustion dirtbike would be frowned upon. If studded winter tires in the relevant dimension(s) can be sourced, it would probably be a hoot on snow and ice in the winter when the motorcycle itch is otherwise hard to scratch, and the low weight is probably extra great if you drop it a lot which seems inevitable in those conditions.

I saw a used one locally where the ad stated that a ball hitch carrier was included in the deal. That would make transporting it super easy since I already have a ball hitch on my car, and deadlifting 58kg should be doable. The battery is easily removable as well, right? That would make it even more doable.
Might be a little hefty to carry like this, but it would be humorous:

Won't they have issues with the batteries in the cold? Presumably they don't have any clever "keep it warm" stuff going on with those given the price/general use case?

I would assume that it's potentially a bit of an issue but as long as the pack is easily removable there's simple and effective workaround. I winter commute on e-bikes and I just bring the batteries indoors when the bikes are parked in the cold. Even when it's -20C which is around my pain threshold riding is fine if you start out with a room temperature battery, since they give off a bit of heat from discharge they won't cool down too much. Adding a bit of battery insulation would be trivial on my bikes but I've never had the need.

I've been thinking about this way too much. That seems completely insane. I don't know sport bike riding, never tried an R1 etc. I do know winter roads "close to the arctic circle" and road studded winter tires. I've even tried it on a motorcycle on one glorious occasion probably 25 years ago. On a 125 dual sport. At least 75% of my involuntary dismounts happened on that day.
I just don't understand how it's humanly possible to come even close to using the power of a four cylinder sports bike with the traction you'd have - imagine riding on pea gravel if you are used to warmer climes. Accelerating, braking, turning and staying alive in general would be...complicated. Sure you could putter around safely enough but that's not a bike at all suitable for that type of riding. I'm just imagining the guy absolutely flying down those long, deserted straightaways you find in the northern boonies of scandinavia (looks like it in the picture), one unforeseen thing away from death. Stray reindeer are common up there, there are lots of bigger animals too, and they don't look both ways before crossing the road.

Welcome to Cycle Asylum, friend.

Thank you. Slavvys answer is probably closer to the truth than my fantasy of speed. If so he's just a silly man who would be way better served by a 125 dual sport than an R1. If I still lived up there where there's actual snow and no road salt I'd love to get into winter riding on something appropriate to the task. Come to think of it, when I was a conscript soldier we had guys on these attached to the battalion (?) zipping around with messages and small things:



AFAIK they have more modern bikes now but still exist.

If it makes you feel any better, check back in in (checks calendar) 2-3 months when it will be 110 degrees fahrenheit :( . Riding season is backwards in AZ, although if you get out early enough in the summer you can still get some time in.

It actually makes me feel better, thanks:)
June-August means summer break so about 8 weeks off work for me, temps unlikely to go above 90f even if there's a heatwave. Nobody should pity me, least of all myself. It just feel soooo distant right now because I'm an impatient man-child I guess.
I've ridden in 100+f once long ago on a rented bike in the tropics during local hot season. I had no real gear but wore all clothes I could muster so I was pretty covered up. It felt like sitting in a hair dryer jet or something and was pretty miserable.

Basically it. When I e-converted my first bike I had to lace the motor to a separately bought rim since I couldn't source what I wanted out of the box back then, but once I got that in order it probably took two hours of tinkering until I was outside for the first motorized test run. With a bunch of stuff jankily held in place with zip ties, hose clamps and tape (and not enough brakes). Getting the bike done took much, much longer and was way more involved.
E: the bike is still not done if I'm being honest, and it's been about a decade now. Lol. I'm fixing to do it though :)

I think there's good reason for that. There's no universal form factors that would easily work in lots of motorcycles. I'm sure you could develop a kit that would work in one single bike model though, but there's probably not money to be made by doing it.

Or this bad boy with gears and everything so the sprocket is offset, hopefully closer to where it needs to go for good chain geometry:

https://www.aliexpress.com/item/1005006586866102.html

There are battery builders on Ali too who will spot weld up a 72V or whatever pack with a BMS in the dimensions you specify. Sometimes the dimensions are a few mm off and you have to move the BMS cables around to make the pack fit in the allocated space. I know this from personal experience. I've been meaning to procure a nickel strip spot welder and learn doing this for myself for a long time but managed to procrastinate this through learning to take care of my battery packs so they last a long time.

It comes in the color "3000w" too!
Seems like Ali is full of interesting e-moto parts. This kit has a 4kW nominal rated motor (at least in the e-bike world the peak effect at high torque is commonly significantly higher, nearly double nominal on my commuter bike). This motor has an offset sprocket too. You can get a liquid cooled variant of the motor but the one in the kit is air cooled which should probably be ok given 90%+ efficiency and street riding. Also bundled is controller, throttle, switches for the left hand and an lcd panel:

As someone who was conscripted to crew armor in peactime decades ago, this is still nightmare fuel. ATGMs are scary as is, even worse if they can move about faster and more nimbly than anything else on the battlefield in silence. We never practiced against simulated drones because they weren't a thing back then but simulated ATGMs kicked our asses on the regular.
