    Opportunity Charging in the UK/Belgium/Holland

    Next week my wife and I are heading to Glasgow to start a month-long ebike journey throughout the UK. Though I have had great success opportunity charging throughout the US (see my 2014 trip), I suspect that this will be considerably more difficult in the UK and Europe. We'll be riding two of my...

    First dead Hall Effect Sensor - 14k miles

    So after priding myself as a man who takes care of his hall sensors, and yes, perhaps even bragged about it from time to time, I have finally ended up with a dead one. 4 years, 14k, and a world record later first dead hall sensor. :twisted: :twisted: Interestingly, it has failed such that it...

    ISO Bicycle Standard Motorcycle Disc Brakes?

    Unfortunately, I am not offering these, rather I would like to identify a solution. I need something much stronger for my Puch Magnum project. I am using a hub with bicycle standard ISO disc brake mounts. I have tried some of the most intense bicycle brakes (Hope mono V2s) and they're just...

    4500+ Miles US Ebike Tour - August 2014

    So I guess I'm getting closer and closer to actually doing this. Here is a very vague plan: The idea It came to my attention last year that the world record electric bike journey was at a mere 2500 miles. I knew full well that Justin had done more than that on his cross country Canada trip...

    The deal: Fill out the survey here!: http://troyrank.com/?p=2177 The survey is 5-10 minutes, and should be kind of fun if you're at all interested in ebikes, motorbikes, EVS, Pizza, living forever, etc... :mrgreen: The progress bar is pessimistic and it goes faster than it really suggests. As...

    The ultimate onboard charging solution

    After spending several years with crappy hobby / questionable chinese quality charger setups, I decided enough was enough: My new requirements for charger: -Onboard, automatic, simply plug into the wall and walk away. -82-84V - >350W -Constant current -Hands-off (no explodey) -Waterproof!

    Galaxy Note 2 Ebike handlebar Mount

    I had this wicked handlebar mount I installed yesterday. It looked a little weak, so I epoxied it together to make sure I wouldn't lose my $600 phone. On my way home, the 2nd time I used it, my phone popped out. I turned around quickly, only to see it get run over by several cars... I'm...

    Ebike Touring Adventures

    I thought it would be cool to start a thread to share some of the adventures I have, while touring around on my ebike. Long range ebike trips are nothing like any other form of bike travel. 2013 Electrathon / Green Grand Prix Part 1 I was able to take last friday off as a volunteer day, in...

    Elon Musk's - Hyperloop

    "a cross between a rail gun and Concorde." I Just heard the keynote with Elon Musk for SXSW. He was asked about his idea for a "hyperloop" which is some sort of terrestrial form of transportation, which cannot crash and is not affected by weather, but it somehow not a train. Can run on solar...

    Shwalbe Super Moto Bicycle Tires

    I've heard of these before, but I'm getting a little bit tired of my hookworms (though I love them) They're a little bit too soft, and they tend to get eaten up by road-junk. I have 3000 miles on them or so, and while the front holds up just fine, the rear is getting punished. I wonder if I will...

    Controller Connector Manufacturer/PN

    Hey guys, I'm trying to get the correct crimp tool for use with cycle-analyst/Ebikes.ca standard controller connectors. What is the manufacturer part number for these guys? I feel like it is some kind of molex/JST/samtec type connector but I haven't been able to pin it down. Can anyone point...

    Where to get 9C Motors?

    It doesn't seem like many people are stocking these anymore. I think the 9C would work really well for a friend who's building a bike, but I can't seem to find them under $350. Does anyone know anyone who has stock of these 9X7 at around $250? Thanks!

    Perm PMG 132 Reverse Brush Configuration - Brush "timing"

    So I have this gorgeous Perm PMG 132 courtesy of Methods. However my design has changed a bit, and I'd really like to use this motor on a left hand drive bike. Since the motor is designed to be a clockwise turning motor, this isn't going to work as is. So my question is: What exactly determines...

    Mission Motors ditches Motorcycle Production Goals?

    Just went to the Mission site for the first time in a few months and noticed that the mission bike is no longer the end goal, but rather a "Technology Demonstrator" It looks like they're selling components now instead of the whole bike. This is pretty cool, because there are specs from all of...

    AST CDS150 500W to 32kW Water Cooled Industrial Motors

    Just stumbled across this on google adsense of all places. The largest motor looks pretty nice. It's a little on the heavy side, but 74Nm torque is pretty respectable. I've sent them a request for a quote. Would be nice to have a curve datasheet too. http://www.astli.com/cds_series.html

    Sevcon Programming

    I'm leaning toward building a brushless, big-motor bike as my next project. The main problem is that even though the Sevcon controllers seem pretty amazing, but the programmer is a grand. Is there anyone that provides a service to program these? Any ES hobbyists have one of these bad boys? I...

    Trek 1.2 Lightweight High-power hybrid-unlimited pedal range

    So I've been doing this whole Electracycle thing for a while now, and it owns. I love my ebike. I love having 3kwh at my disposal. I love that I can load 60 lbs of gear without batting an eye, and I love real acceleration. However, what I have with that bike (as most of us do) is a fast...

    Trek Ride+ Battery teardown

    So I was lucky enough to stumble upon a trek ride+ ebike battery. From what I understand this is essentially Trek's ebike platform. They're using a 11s4p configuration sony konion cells. The cells were at 0V when we pulled the pack apart. I suspect the Battery Protection actually killed the...
