Okay, this really started (for me, at least) with augidog’s “Creative Interpretation” thread, but I’ve been asked to start a thread, so I will.
Combining the above with the ongoing thread post in the Electromotive thread;
And
The second paragraph of that last post is a separate can of worms.
I invite any and all ideas, critiques, addendums, whatever you might have to say. I will say this - such a system bulks up a good bit, although you might be surprised by how small/light it can be made if one is willing to spend the money (look at Matt Shumate’s electric recumbent).
For my own purposes and needs, I want a trike. Either delta or tadpole, although I personally prefer a tadpole configuration. Delta trikes are MUCH more common, and much easier to get as already functional bikes. So, I am working on such a system plan, as I told Mountainman:
I am, at this time, putting together a simplified plan to implement just such a system for a delta trike. It will be somewhat generic, as of course the individual component choices made by each builder will vary somewhat. The major system components are, however, pretty much the same as I envision it:
1) 2 cycle gas powered portable generator, as light and physically small as can be reasonably achieved, capable of producing approx 1 KW;
2) A battery pack - number/size of the batteries again being somewhat variable, but practically speaking capable of at least 24V, and a range of at least 15 km at full charge without the generator;
3) Motor/controller capable of powering the drive wheel(s) with reasonable acceleration, and of maintaining 20 mph on level ground; and
4) capable of propelling a 300+ lb load as described above - your average guy being around 200 lbs, the bike and system being another 60+, and a small payload capacity.
Multiple gears, with electric power delivered through the bike's pedal drive train, are a plus; as would be regenerative braking. Lots of little add-ons that would be nice; for instance, a good, bright lighting system.
Still working on the details at this time. Feel free to take the idea and run with it - from my point of view, the more bikes on the road the better, and such a system does not lend itself readily to abuse with high top speeds, etc.
