PowerKit Pro is one motor, PowerKit Race is two. 2500-3600 euros. Not cheap. Cool design, though, for sure. Regarding pedaling: I'm with you. For me, that's a definition of an ebike, as compared to a motorcycle/enduro/scooter built on a bike frame. I have to be able to meaningfully pedal at a...

It depends on the regime of motion through the air. With one exception, all of the examples you list are transonic. The exception is the bullet train example, but they do not, in fact, have pointy noises. They're smooth curves. For example, compare the nose of an A-10 to an F-15.

I don't think I've ever been as excited to see what happens when a build is finished as I am with this one! Absolutely amazing work. I like the red color scheme with the Z logo.

That is a gorgeous bike. Well done! Can you share any of the technical fabrication details? I have little welding experience, but I aspire to do custom frames like this. What kind of equipment did you use? What kind of jigs did you make/use, if any.

That's a Cargo Monster: http://t-cycle.com/cargo-monster-load-carrier-c-2/cargo-monster-p-34.html.

My bike is not a scratch build--it's pretty standard. But here's my perspective on long tail (cargo) bikes: I recommend them! I use mine for commuting (about 20 miles round trip), and I really love having the cargo space. I usually need to take a bunch of stuff back and forth (computer, books...

So far, I'm pleased, with the caveat that these are the only batteries I've ever owned (it's my first ebike). My main reason for choosing them is the light weight of NiCoMn: the 13Ah pack I have only weighs 8.8lbs. That helps keep my total bike weight at around 60lbs, which, if you check around...

Thanks, Chalo. Sound engineering advice, as I've come to expect from you. BTW, I'm starting a new project that will bring me to Austin occasionally. Perhaps we can meet for a beer and e-bike mini-nerdfest. :)

Hi Chalo: As I mentioned a few posts above, I've been reading your comments on this topic for some time and am going to experiment, but I'm very risk averse regarding pinch flats, especially on the rear since I do carry a fair amount of cargo. Currently, I have my BAs at 45/40 psi rear/front on...

Yes... I meant "required if you want temperature measurements". If you don't disable them, then one has to have a motor with a temp sensor installed. The CA V3 does not solve this problem for the end user. Point being: CA V3 just makes it easier to use the temp data, but it doesn't actually...

Well... that's confusing. I thought the CA V3 required a temp sensor installation, anyway, since it just displays the sensor's output (and can use it as a temperature-controlled throttle limiter). In any case, yes, I will keep everyone informed of my (mis)adventures in this area!

Thanks very much, telektik, for the detailed reply and suggestions. I know how to pretty effectively search ES (using google or similar), and already have a bunch of controller setup threads bookmarked. But as you say, there's not really a single canonical source for this info. It may not be...

Yikes. I would not expect small stones to do that. I will be more vigilant. Especially if you do the "dutch method" :D I was impressed and then concerned about how thin the BA sidewalls are. It's quite impressive tech, but, man, it's really thin! So I found some 2.3-2.5 thorn tubes and put...

Ah! Very interesting. I still am at the bottom end of my learning curve regarding controllers (I get the basics of PWM, but don't know squat about how the devices are actually built). On my BMC+Lyen powered bike there is a pleasing low growl as the bike starts up, so I would consider it...

I have BAs 26X2.35" on my Troll/Xtracycle. I put the 29er Cascadia fenders on since they're 65 mm (2.56 in), and they fit and look great. There's plenty of room on the front (the Troll fork has massive clearance), and even though the fit was tighter on the Xtracycle, the rear fender went on...
