Are ebikes not like hybrid cars and charge battery when going downhill?
i'd suggest you rent one and try it. You'll probably be planning on adding a conversion kit to your bike within about 15 minutes into your first ride. It's a bonus that you live on flat terrain. ebikes are not just for elderly. in fact, pucker factor can be quite high.I had no awareness that ebikes are already such a big thing. I live in flat area and have an almost 30 year old mountain bike with steel frame that is very light and can easily be carried up the stairs or over an obstacle. I don't ride to get to places but to move my legs and be out there, so not really an E bike candidate. Though I can appreciate the benefit of motor assistance for elderly people going up hills or hauling loads. But in practice all I see is kids speeding on shared paths without even using the pedals and being hazardous to pedestrians. I think some restrictions and licensing would be beneficial at least in our area.
I always preferred belt drives over chains from my motorcycling days. i think belt drives would be a good fit for an ebike. cleaner anyway.Straying off-topic a little bit, but I considered something like this when I was planning my e-trike. Basically, what I was thinking of was trying to make a bike with no chain! Make it a pure electric rear hub motor bike, and use the pedals out front to crank a generator to charge the batteries. No direct connection between pedal and wheel, just electrical wire. Merely pedaling to charge the battery.
I determined that doing so would be possible, but probably not efficient. You have a power loss of at least 10% turning electricity into motion. You have MORE than that much loss turning pedal power into electricity. So, something like 30% or more loss in the system. VS a regular bike where the chain drive only has about 3% loss. I guess it would be good for allowing the rider to pedal at a constant "moderate" rate, thereby getting some charging on the flats, and using the extra power to get up hills. I ultimately decided it was too complicated given how inefficient it would be. It also wouldn't have the same pedal "feel" as a bike, which would be weird.
As-noted hub motors CAN regenerate if they are set up to do so. Mid mount, because the motor at the crankset does not get force-turned by the momentum of the wheels when you are not pedaling, do not regenerate.
I was a "biker" on motorcycles for decades. My advice to you is, don't be afraid of turns and corners. Leeeeean into them. The faster the turn, the more the lean. It's okay as long as you don't scrape part of the bike on the pavement. Two wheels will corner a lot faster than 3. Trikes, for geometric reasons I don't understand, seem easy to tip.I bought a lightweight "low racer" style recumbent bike, and it's great... but, it's more built for straight line speed than cornering. It gets around okay, but I've never been a "motorcycle guy", so I get nervous in fast curves with two wheels. I've been thinking hard about a trike. My creative side wants to build one!
Being a "sports car guy", I want one that will take a corner as fast as I'm dumb enough to ride it. That means, REALLY low center of mass and engineered to handle cornering forces. But, I also want it to be comfortable, lightweight... and cheap. I don't ask for much, right?
It's on my agenda. Somewhere after "finish reorganizing the garage" and "build a drip irrigation system for my wife's garden". I want to at least hack together some kind of ridable e-trike, even if it's not the "ultimate".
I broke a rear drive chain once. On Sunday. No repair available. Motorcycle had to be towed home. Never broke a belt.I always preferred belt drives over chains from my motorcycling days. i think belt drives would be a good fit for an ebike. cleaner anyway.

Or make a reverse trike with two wheels in front and one in back.Yeah, I get it on a pure physics level. Has to do with things like center of gravity and instantaneous roll centers. But, I've made it to 55 years old without a bunch of road rash, broken bones or head injuries, I'd like to keep it that way! It will take some engineering and tinkering to get a trike to handle the way I want it to. That's why I want to go super-low with it. If it's not low, it will tend to lift the inside wheel and want to roll over. That plus some carefully engineered suspension geometry should actually make it corner better than 2 wheels. If nothing else, I'll have fun trying! Maybe it will get me off the couch?
26"-7" in wheels, 3"-6" farther apart than trike average, so the frame/seat can hang below the axles within a wider stance.

Looking it over-Thanks

What did you do for the battery?I built my e-bike a couple of years ago with a “Retrospec” 7 speed beach cruiser and a 52v 1000w Voilamart front hub kit. Lots of fun here on the island where I live, and of course I ride it to the beach…
