    Up-to-date options for geared motors with metal gears?

    This is much more interesting than it sounds at first. I see now there is a reason for the nylon gears. Heh, about that speed bug...that's why whatever I do, it will be dual drive, front and back motors. I considered a DD double motor setup. That would give me fast acceleration and fast top...

    Up-to-date options for geared motors with metal gears?

    I was on the E-bike-kit site again today, looking for geared motors. I saw they use nylon gears. The user Knuckles showed pics of some mushed up nylon gears in another thread so I know I want some darn metal gears in my motor. What are my options? In return for your help I will compile the most...

    Unconventional places to stick the batteries

    Props to the man for serious technical skills, but that is not stealth! I'm talking cylindrical cells throughout the entire frame, then you'd never know they're there!

    Unconventional places to stick the batteries

    Where are some crazy unconventional places to stick the batteries? My best idea would be: As the bike is getting manufactured, cylindrical cells are inserted into the frame. The frame is the ground, and the power wire goes out the seatpost. Good stuff there, but impossible for the average...

    Amped bikes geared motor

    Thank you!!! That was an awesome suggestion, certainly alleviated my concerns about sound. I don't care that it's loud, because the cool futuristic sound makes it sound good! I'll post pics of my bike as I build it, but it'll be a few weeks while I gather money. Thanks for all the help everyone. :)

    Amped bikes geared motor

    Then sound is also an issue. I don't care if it's very loud, but I really care if it sounds retarted, like the noisy grinding gearbox in my Chinese 2 stroke. Since the gears in these things are nylon or something plasticy like that, they should all be pretty quiet and sound nice and high tech...

    Amped bikes geared motor

    Hmm... The AmpedBikes site cites a 4.7:1 gear ratio on their mini motors. Anyone know what it is for the BMC & MAC's? They're the same wattage but there's a lot in there that could be different, I just don't know about, and the most important thing is probably the gear ratio... I may not get...

    Amped bikes geared motor

    So I had this ingenious idea (I thought I did, at least) to build a dual drive bike with GoldenMotor's mini hub motors (supposedly >250 W each) so, I'd make a stealth bike that was about 500W. I had some NiMH leftover from my last project so I was planning on making a giant bottle of batteries...

    Hey, 317537, we were saying in class that putting you in one discourse community doesn't stop you from being in another. So you can post on lots of subforums and be a part of multiple discourse communities. Zoot Katz, I'm putting what you said about the distinction on subsubforums and how bikes...

    Hey AussieJester, you rock. The stuff you've written up is exactly what I was looking for so I'll ask you a few interview questions later. Thanks a million!

    Hey, yaemes here. My real name is James, I'm 19 and I've been a lurker here for a few months. I asked a few questions about batteries a while ago and received such great responses that I'd like to be more of a part of the community. I just started studying at Kettering University (I brought my...

    GoldenMotor Magic Pie.

    he's right. in 1 year goldenmotor could very well overtake magic pie and they could easily get to #1 because of people here just linking to it. with goldenmotor's nature as a chinese company, they don't have great customer relations and service but when i looked at their products in arizona i...

    Best way to hook up 60 1.2V cells in 24V? (first post!)

    You linked to a 950mAh NiCd, I have 2300mAh NiMH. Thanks for showing me data.energizer.com though I do not know much about motors but I can guess that it wont be doing its max all the time. Probably only half. So half of 20A is 10A which is equal to 1.45C when referring to to entire battery...

    Best way to hook up 60 1.2V cells in 24V? (first post!)

    The motors at full power would take 20 amps and you're saying the cells would only sustain .5C (1.15 amps), but there are three cells so that makes it 2.35 amps max sustained... That seems grossly underpowered.... this is not very good... how come there are other companies that have NiMH...

    Best way to hook up 60 1.2V cells in 24V? (first post!)

    Thanks for the responses. I am learning a lot! They are 2300mAh Energizer AA batteries. Being able to charge in series is great (I had no idea you could do that) but I still want a 24V setup. I think I will set it up so I can take the battery container out of the bike, take it inside and flip...

    Best way to hook up 60 1.2V cells in 24V? (first post!)

    Make a 24V pack of 20 cells in series then hook 3 packs together in parallel? Also that diode idea is smart. But that means charging 30 batteries in series, and I don't have a 36v NiMH charger and charging them individually makes them last the longest. I like the idea of a pack I could just...

    Best way to hook up 60 1.2V cells in 24V? (first post!)

    I've been lurking for a few weeks. My 24V eBike is going to be a bit ridiculous. Thanks to an earlier project I have 60 superb 1.2V NiMH cells. I plan on putting them in a removable case in the triangle and every time I want to charge them I'll have to individually take them out of the case and...
