Re: Ebike/Moped Gang Cruise Video

Moped are way more accessible than ebikes for a lot of people starting off, and so I want to encourage riding in general. Moped culture is cheeky and fun. Honestly though, the 2 strokes are awful. They actually have terrible range and acceleration. We only rode like 15 miles that night and the one ...

Re: A new trip planner for ebike with consumption estimation

I gave it a try, it's GREAT! Two Questions: 1) Is there any way to enter "headwinds"? If not, do you plan to add a "headwind" feature? 2) Is it possible to access the web app with a smartphone so WHILE YOU ARE RIDING, you can compare the PLAN you generate with the ACTUAL trip? Feedback: YES: Keep wo...

Holy smokes that is one freakin' cool video Troy!

You're "reaching across the aisle" and riding with gasser buddies....that's cool beyond words, dude. You are one hell of a great ebike ambassador, man!

Re: Phat Bike Build

Thanks jkb. The link to the ebay seller of the fairing is the best deal I've seen on anything like that. I'm looking at some aero options for my semi-recumbent LWB and, while there are some really nice options ($$$$), they far exceed my budget. How difficult do you think it would be to mount that w...

Re: Making E-bikes rain / water resistant

"Weatherpack" brand connectors are made for boats and cargo trucks that are guaranteed to get wet. if you needed two posts on a connector, and the Weatherpack pins are too small, consider getting a 4-pin connector and pairing them to double the amp capacity. http://endless-sphere.com/forums/downloa...

Re: Making E-bikes rain / water resistant

Good Stuff SM! Question, though: I've heard from some who've tried cooling oil, that it seems to "wash" the rust off. However, once you do that, applying varnish is a no-go, as it probably won't ever stick to the stator. I'm going to crack open my motors - if they are reasonably rust-free, I'll use ...

Re: The ultimate onboard charging solution

I plan to repeat Troy's/Alan's deal with two HLG-340-48's . I like the flexibility of connecting one LED supply to a 12S portion of the whole battery. I'll split the 24S into two 12S and put a DC-DC converter into each half. That'll give me two 12V outlets I can run lights and charge USB (using a ca...

Re: New Bafang Crank-drives

If you are happy with a max speed of around 35kph, I think the 36V system is a good choice. FWIW I get 25 miles full throttle rides, 100kg rider with the 13.8AH EM3ev 36V. Solid 35kph over half the charge. Tom, your comments are awesome. Makes me insanely curious what a BBS02 could do with 50v 20Ah...

Re: 4500+ Miles US Ebike Tour - August 2014

That enables 150 miles range in 3+2+3=8 hours, an "easy day". 250 miles range in 3+2+3+2+3=13 hours for a "tough day". That makes sense. 15 wh/mile is amazing for touring purposes. If you can average that consumption then you will definitely be doing good. My optimisation point for my bike is right...

Dude, an electric century is tricky with current technology, and it's still an awesome adventure! I am consistently amazed at how far 60 miles is when you take backroads. It's all about charging speed! 45 miles seems pretty low with 1.2 kWh actually, and that doesn't add up at at 13Wh... I don't fo...

The idea of using existing brackets is to have the cost down. Allex, was it easy to get your cell out when you discovered a dud? You need to have support for the cell for the pack to be rigid otherwise glueing them. I think 45C is already shortening cell life and soldering them beforehand does not ...

It's not unprecedented (well during my childhood) to increase the wheel size ten percent, it makes speed adjustment pretty easy. I know it's not elegant, but it's simple. 34mph is 55kph.

Re: Building a battery box, an iterative process.

Jonathan - great photos - this bike is going to be a long-distance, high-efficiency MONSTER.
I can't wait to see what kind of test results you achieve with it....
Great technique and idea on using the strips to fab-up the box. The box looks great nested into the frame the way you have it.
