    Onboard generator

    Usually it just ends up me using bike trails as parts of my journeys. Usually I do about 10 miles on each trail for each leg of a trip? Yeah... people will probably think I’m a cock for having an engine back there, but eh...

    Onboard generator

    Can’t take a motorcycle on bike trails, have to get a license, possibly less efficient than my system (subject to disagreement), etc

    Onboard generator

    I think the big difference is that I already own a generator, so that makes things a lot easier, all I need is the mount. Also... I always feel guilt when I leach power off places, even if it’s only like 5 cents. (0-100% is about 8 cents around here), so I kinda feel obligated to pay for my own...

    You are definitely right in thinking!

    Onboard generator

    I have a 36V ~10A system, so when I’m accelerating, the motor uses about 420 or so watts. However the motor is not always on, so in an average hour, about ~300Wh of power is used(?). The generator can handle up to 1800 or so running watts, and i have 2 chargers, one 5A and one 4A. I can use both...

    The Westinghouse generator I use is an inverter

    Onboard generator

    The big problem would probably be range, because with a second battery you'd have to stop and switch out the battery, which adds time to your trip (albeit only five minutes at most, which isn't really enough time to justify a 46 lbs generator instead, but oh well...). With a generator, the...

    Onboard generator

    if charging as we stop is the question, i think the big generator would be better, since i can get more power out of it. But if i wanted to charge as i went, the Honda might work better

    Onboard generator

    My idea was a sort of thing I could use for longer drives that’s modular to some degree and easily refuelable, that way there’s almost no downtime when I have to do long trips. But then if I’m just going to the shops, I could unbolt it in 10 minutes, and go without it. A gas motor mated directly...

    Onboard generator

    Everyone seems to think this is a joke thread. This is why I do not enjoy using forums. I’m asking a genuine engineering question because I want other peoples opinions on which method of this would be most effective, in theory. Will I actually end up building an on-board generator for my bike...

    Onboard generator

    I really want to just add more batteries, but they’re expensive, and I don’t have a good mounting system. I have a 15Ah “kettle” battery on my frame held in place by hoseclamps, and while the hoseclamps do an exceptionally good job of keeping the battery mount in place (I’m using 3 clamps), for...

    Onboard generator

    That's a really good idea, I'll have to look around and try mine out!

    Onboard generator

    That's a good idea, but the real world is I'd need a really big turbine to generate enough power to have it be worth it. It may add an extra mile or two, but for the price it'll cost, that's not worth it

    Onboard generator

    Personally, I don’t think putting an engine that doesn’t directly power the wheels would do that (though it might get me stopped, to which I’ll have to explain this!) The power to the battery could be coming from a nuclear generator on board for all anyone cares, but at the end of the day it’s...

    Onboard generator

    I’ve seen the video with the guy with the orange generator on the back of his bike (that’s where I got the idea for #2 from) I’m just here to gather thoughts on which one of the two generator methods would be better

    BMW did that, but they did that inside the car (i3, anyone?)

    Onboard generator

    I have thought about it, and while this would probably be more stable for the generator, it risks messing up the handling. I need to find a place where I can like try out a trailer to see how it makes my bike feel.

    Onboard generator

    Before you say “just buy a bigger battery”, well that’s no fun, is it? I want to put a generator system on my eBike (will this actually happen? Probably not, but I still wanna get some opinions on it). The two options I have are this: 1) Buy a Honda GX35 engine, it only weighs 7.6 lbs, and then...
