    The Poorest-Written Ebike Article...Ever?

    http://www.techinsider.io/the-oko-electric-bike-launches-2015-10 Compliants: 1) The BATTERY is in the middle of the frame, NOT the motor. The motor is a front wheel hub drive. (probably geared, from the size of it). This error keeps getting reported over and over again in the article...

    Mopeds in NC Now "Registered"

    Mystery Builds

    Thought I'd start a thread to start asking about ebike/emotor builds I might see out in the world that I've not seen represented on E-S: Let's start with this one: http://cowboybunny.blogspot.com/2012/04/get-rich-or-die-mayan-moped-rally.html It's in the second photo from the top. Anyone know...

    Long Distance Ebike Design

    Wanted to start a discussion about a build of an ebike intended to be a long-distance machine, something you can do 100, 200 or even 300 miles on in a day, at an average rate of about 25 miles per hour. Example questions to discuss are: - What drive system would you prefer? A hubmotor (DD or...

    How Do States Treat eBikes?

    Thought I would post the question to E-S and invite members to chime in with citations of the law in the various states. In NC, the closest we've come to regulating ebikes is a proposal to regulate "Mopeds": The (in)famous NC Legislature, making it's mark on history passing some of the most...

    Ride the Future Tour

    I am JONESING for this something bad. And I put it in the ebike section because ebikes are participating: http://ridethefuturetour.com/ I'm thinking a few more Ah of LiPo and I'm there.... (Moderators - modify or move the thread as you see fit. I did a quick search of E-S and didn't find the...

    2000 Honda Insight: Convert, or No?

    I own and have been a happy driver of a 2000 Honda Insight now for almost 12 years. In that 12 years, the car has had four catalytic converters: the factory original and two that Honda put on. One, the last one, I put on. Now, in 2013, the little old Honda Insight wants to exact it's Catalytic...

    ebikes on Tour de Cure?

    Soon, the season for the Tour de Cure rides will begin. I've searched the internet and the Tour de Cure websites (example for my area: http://main.diabetes.org/site/TR?fr_id=8620&pg=entry ) and I see nothing mentioned about using an ebike on the ride. Does anyone on E-S have experience riding...

    Phat Bike Build

    Here's the before photo right after getting the bike home from the LBS. It's a slight knockoff of the Electra Townie, but with less of a crank-forward emphasis and a slightly smaller (but still big) central triangle. The tires on this bike are HUGE: 2" thick, 26" diameter. The thickness of the...

    Adding Throttle to Multispeed Bike

    We've got full-grip throttles, thumb throttles and half-grip throttles...And none of these will work with anything besides trigger shifters without removing the shifter and losing the gearing. I see some bikes in which the front derailleur is removed completely and the chain runs on only one of...

    New "ePEDALER" Magazine

    Got this in my email today, thought it would be good to spread the word among the E-S faithful: Seems like a positive development for all of us here on E-S. However, in the US, I would call this "big news" for ebike folks and at least "newsworthy" for the unwashed masses. What I put to you...

    9c 2810 in a 700c wheel?

    I'm considering trying a 9C DD motor in a 700c wheel. These motors aren't light - 10-12lbs minimum. Has anyone out there ever built up a 700c or 29'er wheel with a 9C DD in it? If so, how's it working out?

    What is an efficient ebike?

    Seriously....what is it that makes a very efficient ebike? We've got a unit of measure that works: watt-hours per unit distance, commonly expressed as Wh/mi or Wh/km. That's offers us an excellent starting point to define meaningful efficiency ranges for ebikes. However, the question...

    9c 2810 and 2812 Measured Speeds

    Using a CA to measure "freewheeling" speeds of the 2810 and 2812 motors at 18S (74V nominal) and 24S (96V nominal). To estimate real-world speeds in neutral wind, subtract 2 mph from these numbers on a recumbent, 3mph on an upright. I determined those "differentials" through testing on my SWB...
