    Idea: Separate forum sections for parts, bikes and 3+ wheels

    Heh, no, but I get what you're saying. And I am extremely grateful to you and the other Admins, what a kind thing to do, thank you! The site I'm thinking of is another labor of love, bentrideronline, although I think they might make revenue somehow, I haven't looked into it. Ads aren't the...

    Idea: Separate forum sections for parts, bikes and 3+ wheels

    Thanks Dan, location would be a big help too. At the end of this post, I suggested a syntax, which could be put in a sticky for mindful posters. (and could also work for form-generated titles, although that would require modifying the code of the BBS) Thanks Amber, it does make more sense in...

    Idea: Separate forum sections for parts, bikes and 3+ wheels

    Hi, I noticed it's tedious when looking in the for sale section for an entire ebike/vehicle, because they're sprinkled in amongst the many posts of parts for sale. A separate section for whole e-bikes could make it a lot easier to find them. A third section could be good also for e-(velos...

    [Build Advice] Best setup for $1500 that goes ~50mph?

    Wow, I was not expecting that, thanks Dauntless! Sure am glad I replied to the topic just so I could get the email alert and read your post. That thing looks like it would work really well, and my initial reaction was wanting to get one. But the more I thought about it, the less safe I think it...

    [Build Advice] Best setup for $1500 that goes ~50mph?

    First off, I agree wholeheartedly with amberwolf ohbse and spinningmagnets. First I'll share a story from my experience, and then I'll give you my recommendations on making your dream possible (albeit with a couple major changes) One time I was on a commercially produced gas moped, (~150lbs...

    (answered) advice on last bits n pieces for etrike (fuse..)

    I did heard back from the store, so I took out the line about that in the first post. Also just wanted to edit/update this thread as answered. I renamed the thread "(answered)" and I have placed this line in the first post: " [THREAD ANSWERED (thanks WesNewell and Dogman Dan) AND HEARD BACK...

    (answered) advice on last bits n pieces for etrike (fuse..)

    Hey thanks Dogman Dan, I appreciate your setting me straight. I've since read some posts about crimping/soldering on the forums, and I feel I understand it better now. I learned that the solder has higher resistance than the copper wire, but it can help transfer heat, if applied as a thin layer...

    (answered) advice on last bits n pieces for etrike (fuse..)

    Thanks for your advice, I didn't realize there was anything wrong with it. I'm glad you saw it and posted! That opens up the options, I'll check what other people use. (About "crimping" instead of soldering: The local ebike shop owner recommended against crimping due to it forming "hot...

    (answered) advice on last bits n pieces for etrike (fuse..)

    [THREAD ANSWERED (thanks WesNewell and Dogman Dan) AND HEARD BACK FROM STORE - THIS POST LEFT UP TO AVOID CONFUSION} Hi all, Almost there - this etrike runs, now all it needs is a 40amp fuse and a switch, and maybe a relay. I don't know where to get them, or which ones would be compatible with...

    Stumped about wiring new throttle to e-trike

    Hi Ykick, You can just have it, but there's a few things to know, so let me know if you still want it. 1. You may have read that the plug's been cut off, but I didn't think to leave enough wire on the plug end for it to be able to be wired back on, so unless you wanted to solder it back on...

    Stumped about wiring new throttle to e-trike

    Thanks John, but I came to considering that throttle by a different route, so your insight was really just confirmatory and very much appreciated, and I am happy with the purchase, I agree it's expensive, but they are a currie authorized dealer, which I find reassuring. I decided to save myself...

    Stumped about wiring new throttle to e-trike

    Thanks John in CR and D8veh, I appreciate your help. I was getting a bit frustrated and worried that I might fry the controller because I didn't know what I was doing. I decided to go ahead and order one of the 5k ohm pot throttles you mentioned John, thanks, and this one luckily states clearly...

    Stumped about wiring new throttle to e-trike

    Hi, thanks, I did both ways and it didn't work either way. I also tried unplugging everything and doing it over again. The battery still makes a spark crackle as it's plugged in,(which it did before when it worked) so it's not the battery wiring, nothing has changed since it was working with...

    Stumped about wiring new throttle to e-trike

    Hi, I'm a bit stumped. I'm trying to restore a used tadpole style e-trike (bought with no battery) and I need to install a different throttle (I wanted to put a thumb throttle on it to make it easier to activate on the upright handlebar, and accidentally broke the old one while removing it, so...

    Oil cooling your hub- NOT snake oil!

    Correction about my glycerin experiment: The glycerin is not "easy" to stir as I described. I had stirred it with my finger, which I now realize warmed and melted it instantly(because it's similar to oil), explaining why I cut through it easily. Stirring it with a spoon shows that it was quite...

    Oil cooling your hub- NOT snake oil!

    Re Viscosity of Glycerin at cold temps: I ran an experiment by putting some in my freezer overnight. It does become more viscous, but not in the same way that sugar syrup does. If I tip the container, it moves slowly, but when I stir it, it's very easy to stir, very little resistance, so it is...

    Oil cooling your hub- NOT snake oil!

    Ok, for starting the motor in a cold region, glycerin might be pretty viscous, although it's no where near as viscous as sugar syrup, because it's shares some properties with oil. (remember oil is a triglyceride with some hydrocarbons attached) I am mainly concerned with noise reduction, that...

    Oil cooling your hub- NOT snake oil!

    I'm thinking Glycerin over Mineral Oil, for better heat dissipation and sound reduction: Thermal Conductivity: Mineral Oil = 0.133 W/mK Glycerin = 0.290 W/mK (more than twice the heat dissipation of Mineral Oil) It is more viscous, so it will produce more drag, but the...

    Request video or audio recording of oil cooled MAC or BMC

    Hi, I'm deliberating between Crystalyte HS2440 (for front wheel of trike, can't use a rear hub on it) and an oil-cooled MAC or BMC. The issue is noise. I know the other pros and cons, which is why I'd like to go with geared if the oil can make it quiet enough, but I've never heard one running...

    Which is quieter, MAC or BMC?

    Kin, thanks, I am shelving the insulation plan for now since active cooling is a bit complicated for me right now. Maybe later though. Triangular troughed foam panels can break soundwaves, but you need a 100% membrane, no gaps, like a true seal. Ben Wilson, that's good to hear. I did listen to...

    Oil cooling your hub- NOT snake oil!

    Oops, didn't see the other replies verifying that it's quieter, I just followed the link from my email alert and it led me to page 18, didn't see page 19. That's great news (that oil reduces noise), I guess it's to be expected, but I'm really glad to hear it helps. I just found this: "Super...

    Which is quieter, MAC or BMC?

    A sine controller would be awesome, but are there any sine wave controllers that don't cost an arm and a leg? They seem to be in the $500 range. Worth it if I had the dough no question.

    If I have the following, do I need anything else for Ebike?

    Oh wow, that all does sound important. Emergency cutoff, fuse, battery management system, ok looks like I won't be just sticking a battery and controller in there after all. Kin: "A bike" :lol: Immediately the image of a unicycle with a hub motor flashed into my mind, with the torque arm...

    Which is quieter, MAC or BMC?

    Kin, thanks, it's almost entirely high pitched sound that I am concerned with, the gear grinding noise doesn't bother me, so the light weight/foam route should work for the noise. As for the cooling, that's where it gets complicated. I'm going to put a pin in sound insulation for now. I did...

    Which is quieter, MAC or BMC?

    Thanks. Yeah, I'm aware that they are pretty close, maybe there's no noticable difference. I still might go with a DD, but there are the obvious drawbacks. (climbing, weight, coasting drag) I think it might be possible to use a cooling system with a geared motor, and then insulate it with a...
