    Crazy Trike concept, need some help/advice

    So I have a weird, crazy Trike concept, and having some trouble finding parts which may work. FYI this would be a build for Burning Man, so thoughts are based on having LOTS of cushion for when I/friend/someone else does something stupid/crazy. My initial concept is based off of the Lode Runner...

    Mid motor, BB or non-BB?

    Thanks amberwolf, those are some nice, interesting designs. Not sure I'll be doing them soon, but definitely something I'll come back and reference when I get ready to do my own :)

    Mid motor, BB or non-BB?

    Well, as I said I'm not buying it, although I think I will use it for inspiration.

    Mid motor, BB or non-BB?

    It's a standard BMX 20", and according to hike at ~40psi it was almost flat/compressed due to the weight. And the foam thing is the equivalent of 120psi. Why he didn't go with a high pressure tire/rim, I dunno.

    Mid motor, BB or non-BB?

    So got some pictures last night (https://imgur.com/a/pT3XD0g), pretty cool design...but it's big. Large. And where the heck would I keep it when not using it?! I'm in a small 1 bedroom apartment, no real space to put it, and no way it can fit in my storage spot without paying a lot more for a...

    Mid motor, BB or non-BB?

    Just found https://lunacycle.com/parts/cyclone-parts/cyclone-double-sprocket-kit-for-trikes-recumbents-and-pedicabs/, which actually might work out just fine. Since there's a gear shift, it has a tensioner, and worst case I can always get a chain idler/guide or another tensioner. There's one...

    Burning Man SLA version 2

    So, poking through an old memory card briefly this evening, found this old image of my 2nd attempt at a Burning Man e-bike. I took 4x12v SLA batteries, welded steel square tube rear panniers. Good thing the bike frame was steel. Twisted the whole damn bike every time I went over a bump, and...

    Mid motor, BB or non-BB?

    It seems like it might be a custom build, I'm going to see it tomorrow and intend to take some more detailed pics and measurements. It's already got a transaxle (yay!!!) so DD rear hubs make less sense. Frankly I'm planning to do this as a Burning Man build, and possibly do it effectively as a...

    Mid motor, BB or non-BB?

    So I'm looking at an interesting used cargo trike on CraigsList, delta upright, cargo area back, and it's got a transaxle in the middle which the pedals (above the front wheel) go to with gears, with 2 separate chains going back to each rear wheel. If I get it I'm going to electrify it, and I'm...

    Presta -> Schrader rim?

    OK, so in general drilling out doesn't present a problem and is fine. Great! Thanks everyone.

    Presta -> Schrader rim?

    So...I've got a Presta rim on my bike (going to be conversion), and I'm debating if I want to go for schrader tubes and wanted to get your opinions on (carefully!) drilling out the hole to fit a schrader valve. I've seen other people have done it (https://www.youtube.com/watch?v=w3-8rkazaOw)...

    Spoke length calculation help

    Sapim makes spokes 13ga at the elbow, 14 GA rest of the spoke. Sapim Strong I think they're called. To answer where I'm buying them from, http://wheelbuilder.com/ although you can get them elsewhere such as http://ebikes.ca/. Mostly I'm buying through them because they're very close to me so...

    Spoke length calculation help

    It's double walled rim, so less worried about the the spoke tips poking through a few mm. I'll go for the 203mm then, sorta split the difference. I'll go for the slightly longer nips, and that way there will be some room to play. I'm actually going to have a bike shop lace it up, since I don't...

    Spoke length calculation help

    So I'm using 2 different spoke length calculators, http://www.ebikes.ca/tools/spoke-calc.html and the Sheldon Brown spocalc http://sheldonbrown.com/rinard/spocalc.htm and they are giving me close, but different numbers. I've got the MXUS XF07 hub motor, and took my measurements off the presets...

    Question on re-lacing hub onto new frame

    So I'm looking to re-lace a MXUS XF07 (front) onto a new rim for a new (to me) bike. It's a 20" rim, and I've seen some advice recommending a radial pattern, and others recommending a single cross (http://www.ebikes.ca/learn/wheel-build.html). Right now I'm inclined to do a 1 cross, especially...

    Trouble with CAv3 & TDCM sensor

    Ah, I see. Ok, so, something happened with the wires, any suggestions for troubleshooting if it's the cable from the connector to the CA, or if it's the cable coming out of the actual TDCM itself? My only thought is to use a battery and an LED or something to check if the power makes it through...

    Trouble with CAv3 & TDCM sensor

    Also, I'm now not getting any pulsing or dropout like I was when I first installed it. Could you guys somehow have send me a THUN?

    Trouble with CAv3 & TDCM sensor

    So, setup as 1 wire & reverse, I get PAS. Strangely, I get some (a very little) while pedaling in reverse as well. The D remains pointed down, the P still alternates up/down. When the PAS sensor is completely unplugged both point upwards. Something else I can check?

    Trouble with CAv3 & TDCM sensor

    I'll be heading off work in a bit, I'll check if I unplug it what the CA says then. And do a brief test with 1-wire & 5v = Rev. The wire has a bit of tape wrapped around it where it exits the BB, although otherwise loose in the hole, so I don't think it'd have worn through to cut one or more of...

    Trouble with CAv3 & TDCM sensor

    So the actual static values are 2.52v 2.7Nm with brakes and full force 3.3v 23Nm. This was after biking at speed for about 30min, and are different than what I saw when I first turned it on. I also flipped the bike and unplugged/replugged the sensor. D has a down arrow, whatever I do with...

    Trouble with CAv3 & TDCM sensor

    Going from memory here, the voltage when no torque is something around 2.42v, give or take. I'll check with full force when I go down to head home. I don't recall the P & D arrows, although a few weeks ago when I was doing some maintenance I did pull the plug apart to do some wiring cleanup, so...

    Trouble with CAv3 & TDCM sensor

    Attached is the config I had loaded up this morning. I have the eZee rear kit (eZee700R ) from ebikes.ca, CAv3 DPS, C3625-EZ_R controller, TDCM 120 kit. And like I said, the torque scaling I'd consider only vaguely accurate. I used 2 1-liter plastic water bottles in a small cardboard box. I...

    Trouble with CAv3 & TDCM sensor

    So I'm having major troubles trying to get my CAv3 & TDCM sensor to play nicely together and give me a good PAS experience. Frankly, to get much of any PAS experience currently. Originally I had some amount of responsiveness, although it wasn't very good & pulsing a lot, but lately even going...

    Electric Rider vs Amped vs Currie

    Yea, Amped seems to have gone AWOL. I got their front wheel kit, SLA instead of Li, and it was nice, easy setup. Until I accidentally blew up the controller :cry: Went on the website and ordered a new one, couple days later got a canceled order email and PayPal refund, and the website was no...

    New controller needed

    Wow, got my new controller FAST. I wasn't expecting the FedEx option to be next-day. For only $10 more over the Canada Post options, although I imagine if it had been something heavy like batteries it would have been a different story. Either way, I think next time I'm doing any e-bike parts...
