    Do you run across overly competitive/aggressive cyclists?

    Ya. Bad choice of words and i let jargon in. I meant more that some cyclists are a-holes who judge people on their body and look down on people that aren't "fit"

    Do you run across overly competitive/aggressive cyclists?

    I can provide some counter perspective here. Context for my ebike experience is: I got my first ebike to pull the kid trailer for commuting about 12 years ago. Kid 1 has since grown well past trailer size, Kid 2 also. Moved closer to kid schools, got a used Nissan Leaf for other kid hauling...

    Sortimo electric cargo trikes

    In the end, it doesn't matter what direction you point the triangle and how you suspend it, it's still going to be less capable of leaning into the turn than 2 wheels and less stable off camber than 4. I'm no engineer, but this just seems like geometry.

    Help Needed with Fastest possible Electric JetSki Conversion

    Yup, water cooled is the trick, and there's not much out there. Someone with skills and tools could come up with badass custom heat exchange setup to properly cool a suitably powerful electric motor. doubtless someone already is, and it will be released in a year or two by an existing oem like...

    Bollinger SUT

    Saw that earlier today. Love the overall approach of using high tech where it matters in the drive system, and low tech when it comes to the 'car as living room' aspect of automotive design. I'm not so keen on the total lack of aerodynamic consideration -seems a bit of a miss. Forgivable if...

    Buying used Leaf in USA - general advice?

    The family is taking a trip this August to see the eclipse in Oregon, then to the dunes and redwoods before heading back up to Canada. I'm now convinced this is the time to bring back an off lease Nissan Leaf with us. From what I can tell - prices on used Leafs in the USA are 4-5K lower than...

    Bicycle Conversion Recommendations

    I have no horse in this race so to speak, but i think you should seriously consider the Kepler drive. Do a search here if you haven't already. It would be quite a bit more appealing to someone who just wants a boost. San Diego is relatively dry and flat. You can go with super...

    TESLA JUST PASSED GM AS THE MOST VALUABLE CAR COMPANY

    I'm surprised there is no mention in this thread that tesla's value is not just that of a car company but a big data company. Every model s and x out there is gathering what is likely by far the most comprehensive database on real world driving conditions and telemetry, providing tesla with a...

    24 Volt Trolling Motor Battery Build/Questions

    Use 7s. Safe replacement for 24v lead and the bottom is still well above the average for the 24v lead if you are looking to boost power. If the standard power for the motor is enough for you then it's worth considering 6s even, so you can use a standard hobby charger.

    The claim to be patenting graphene supercapacitors smells like vapor marketing to me

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    I ordered from tumich last year and no problems. It's up to you if you want to take the risk of shipping without insurance as stated clearly.

    14S cordless tools on a 14S ebike pack

    The newer higher end >40v yard tools almost certainly come with controllers with temperature monitoring and roll back or shut off. Even my much older solaris 24v mower that i converted shuts itself down if I get too much clumping of wet grass. I just got the ego 15 inch string trimmer and...

    Fifield Inc.

    Why they would put such a pimple of a generic bottle battery on a lovely steel frame boggles me. Especially when shelling out for the alfine 11. And at 5500 to boot.

    Would this pinion with rim-rack drive idea work?

    Seems like it would be hard to manufacture. UHMWPE does not deform easily, which is the point. So how are you going to radius a strip of milled material to the diameter of a bicycle rim? You could mill the curve itself out of a larger block but that's going to be harder and burn a lot of...

    14s7p Panasonic PF build - current sharing advice

    I'm about to start on my third battery build. First was a recycled toolpack cells from Makita packs long ago that I put together for my lawnmower. I learned there that even if it was OK to solder cells, I'm nowhere near good enough at soldering to make it OK for me. I also learned I don't...

    Airbus subsidiary APWorks 3D Prints ebike

    Lock, how you manage to post all these awsome finds over all these years amazes me. Kudos, this is one of the best yet. To all those who may gripe at the list price, some of the ultra - rich will always buy hugely expensive toys , isn't 35kg of expensive metal and rubber a less gratuitous...

    10s3p best 5x6 layout for current sharing?

    Hi, I'm getting set to build up my first battery with the JP spot welder. This one will be a 10s3p mini pack using panasonic 2.9Ah PF cells, and I'm planning on a 5x6 rectangular layout, partly to make a nice compact shape that can fit in a seat bag, partly because I got the batteries (from...

    JP spot welder

    Jakov, I finally set up the welder and tried a couple test welds on old cells. I'm very impressed with the quality. Thanks for providing this kit as it allows us non-technical people to finally build a proper battery.

    Is there room for a new electric bicycle company in the US?

    Ebikes will take off in North America, but when is the question. The latest crop of demi - adults is far less interested in cars than the generations before thankfully, but current ebikes are still hitting it off mainly with nerds, seniors and DUIs. Style is a big part of that. I think what...

    Discussions aren't the same quality without Chalo

    Welcome back. As a perpetual noob when it comes to the E of ebikes, but one who's been rebuilding and maintaining a bicycle as my primary transportation most of the last 30 years, I can attest that you're clearly a top flight bike mechanic who has been most generous with his time here and...

    Solar PV Will Be Cheapest Form Of Power Within A Decade

    You working for big oil? Signing on to forums to rag on renewables by pointing out the obvious as though it's a disadvantage? Sorry if I'm way off base here, but signing on to a forum like this you'd think you may have something to say about electric transportation rather than two non-sequitur...

    JP spot welder

    I've been wondering about this. I'm a newb/hack with basically no electronics experience or skills. Still, just got my welder, and I would've thought it would be much easier to solder the balance wires on before spot welding the pack together.

    Building a 72V ebike

    Do the laws in Belgium allow you to run those speeds? I'm pretty much a libertarian but if my employment depended on running an illegal vehicle through a major metropolitan area I'd think twice. This from someone who regularly commuted on a technically illegal vehicle. You can more easily...

    Burning Man Electric Couch.

    Thanks for this one. I got a big laugh at the 30mph couch line. Please wear excellent gear and find a good empty road if trying it out at those speeds. And get video.

    Linear pull, Center Pull, Dual pivot: What is your opinion ?

    I'd also respectfully disagree that any lever can work well with both cantis and linear pull. The cable travel is too different. A linear pull lever won't have enough leverage on a canti and a standard lever won't have enough travel for a linear pull. It can be made to work, but not well.
