What neptronix recommends there is just about exactly what I did with my old Ryan Vanguard, and it ran pretty well. Except I left the regen configured to the the usual modest force. Then I moved the motor to a Burley Limbo, because the Vanguard is such a fine classic ride on its own, and at the high...

My guess for most frames Bicycle frames, that is, am I right? For an electric scooter, the principles behind bicycle ergonomics are somewhat misplaced. For an ideal ride, some kind of moped frame would probably work a whole lot better. Maybe one of those mini-motos that were popular a few years bac...

I'm interested in seeing how this turns out for you. I've found the opposite; increasing regen decreases range because the bike brakes harder and the time regen is active is shorter. Moderate regen seems to pay the most dividends on my bike, but maybe that also has to do with terrain and riding con...

it would've been a potentiometer mounted to the pivot of a springloaded roller on the top side of the chain, and the voltage on the pot would've been detected by an op-amp and amplified and turned into a throttle signal, calibratable with pots on the op-amp...there are better ways to do it but that...

Different way to say the same thing. If you're shopping for an electric bicycle, and I give you, and you only, $1,500 to help buy a nice one, then that's just good for you. If I give everyone $1,500 max, then the prices will go up so you pay the same. This is more reliably true with something like t...

Yeah, great idea - Federal government doesn't send enough of your tax money to China.

Someone should break it to him, though, that today's cool thing is electric foot scooters.

You'll see a Burley Limbo in Surrey I found that listing. $600, right? It certainly doesn't appear to be anything remotely capable of mountain trails though. Am I missing something? Not at all, it's for roads as far as I'm concerned, though there's likely some grey area between the two - as there i...

I need stuff available here. If COVID restrictions are lifted in short order, I don't mind picking up from a shipping address in WA state. 2) terrain. You might have a look at craigslist. Nothing much on the BC side of the border, but some of your preferred options are to be found less than 100km s...

SlowCo: I have considered a Tongsheng middrive. I watched a lot of Tim's YT vid which were helpful. It would solve the imbalance issue. I would lose my Patterson but keep the Alfine. You'd lose both. Or rather, you'd put the Patterson aside, and you'd really lose the Alfine. The crank drive will de...

It's true that if you have a motor, as long as the battery is good, gear shifts are less important, so it will be easier to get along without the Alfine. Until the battery runs down. Personally, I do shift quite a bit, but the point is I don't strictly need to, so if I'm stopped in high gear, that i...

I'm not sure we have what you want here. The thing for you might be to get yourself to a local mechanic/retailer who takes an interest in these matters. From here, A&B Cycle looks like a good bet. Here, you're going to get a lot of discussion that goes every which way and will be hard to accurat...

You could find a way to hook up a silder switch - like those you find for the dining room table that dims the light. I hooked it to an unused switch on some handlebar control I had - honestly, I forget, which is easy because I never for a moment had any desire to turn the cruise control off. I don'...

If you mean a 30-40' canopy over your charging station, great.

I love regen, but I have the most use for it down hill. For quick stops on flat ground, it seems to me you'd have to dial up the regen force pretty high to get much value out of it, and just generally it doesn't seem worth it. Considering the trade off, which is that you'd need some power to the mot...

If you know how long it is, and how tall the top is, the average grade is the Rise (height / Run (length). If you go to google maps, or maybe "strava", you can use the elevation features to see slopes in some places. What I do: use google maps to get "directions", set the route ...

As MadRhino says, the more it looks like a bicycle, the more it will be like a bicycle. Take the Bianchi e-road: https://electricbikeadvisor.com/wp-content/uploads/2019/10/Bianchi-Aria-e-road-review-2019-675x445.png It's no motorcycle. You get a raging 250W out of this 36V system, and 7Ah battery th...

Also do you have any experience with geared rear hubs or should I not even consider them? For trips like that, practically anything will work, so unfortunately you have to consider them all. I'm kind of prejudiced against crank drives, but people seem to get along with them OK and after all, it see...

Direct drive, with some cooling, controller with regen and 52V 20Ah battery should do it. Basically you're using power climbing about half the distance each way, so need around 18 total miles worth of assist/battery capacity. Or, you can have a smaller battery and assume recouping a portion of the ...

I'm no expert on this, but I think the appearance of a seam is the least of your worries. It's more about having a frame that will handle its stresses well and make for a pleasant ride. Of course also that it's a workable material that can be bent and joined with reliable results, but you can bend a...

Should I use steel or aluminum alloy tubing? ... Also is that going to complete 2 frames and 2 forks? ... I got a mad man helping me who has vision and knows what he is doing with the machines(or actually doing the work). I'm going to guess you aren't going to get plans for this, so you'll just hav...

If I had the money for the tools to do so, I'd give a go at producing such a motor and a matching controller to drive it. I am confident that if the product were good, I'd make a small but reliable profit. As more of the product entered the market, more users and potential buyers could see whatever...

That word "scooter" - hope I never see it or hear it again. Scooter: https://cdn3.volusion.com/qcyhg.zvdeh/v/vspfiles/photos/116-GC440-2.jpg?v-cache=1459175507 Scooter: https://eriderbikes.com/wp-content/uploads/2018/05/cream-color2-1024x1024.jpg Scooter: https://pisces.bbystatic.com/image...

Fluted polypropylene / "coroplast", very popular for home made inventions - light, strong and cheap if you can use discarded campaign signs. It isn't miraculously easy to work with, though. Its durability comes at the expense of being so chemically stable that there's no practical way to r...

They do it for a moment, with all their senses alert, attention focused, mind and body primed to react. For all the good it would do them, if something went wrong. Whatever, it's your ass and no one minds if you do that kind of thing. Like ... say, sailing. Once I talked to a guy who had sailed alo...

People who ride this kind of recumbent sometimes claim that the long frame provides enough suspension already. I don't know, of course that's unquantified evaluation from people who never had real suspension in the first place, but it is a little different from the tight geometries of shorter recumb...
