    Post the ebike law in your area. Here is Florida

    "Responsible" ... there's the rub. That's always been a tough concept for a lot of cyclists, and these days I wouldn't expect things to change for the better real soon.

    Post the ebike law in your area. Here is Florida

    They'll let you go the speed limit. You just have to get a motorcycle endorsement, and an "ebike" that's been through the qualifying process for motor vehicle requirements like lights, etc. And stay off the multi-use paths.

    Post the ebike law in your area. Here is Florida

    It isn't a 28mph speed limit, you just can't get any more help from the motor at that speed. For me, they could just forget all the rest of the rules and use this one. Who cares how strong my motor is, or whether I make pedaling motions? Motor vehicles have a ton of regulations - a handful...

    Post the ebike law in your area. Here is Florida

    Realism is not what it's about. Legislators know nothing about it, and they're trying to satisfy a constituency who knows nothing about it except that electric bicycles are a dangerous kamikaze faction getting ready to invade their neighborhoods. "People for Bikes" is an industry lobbying...

    Post the ebike law in your area. Here is Florida

    The way I read it, that isn't strictly true - the "no hand throttle allowed" part. I see that the legislation requires the operator to pedal, for the motor to work, but nowhere does it say there can't be a throttle. That might be kind of a fine point, but maybe not. More than a few electric...

    1000w or 1500w? Power/range differences

    The hose clamp should be simple to fix, though. Like the man said, simply strap it to the seatstay.

    Regen

    Sure, that's a fair point if the proposition is to eliminate physical brakes and rely solely on regen. I think his point, however, was not that we should follow the lead of that scooter maker and do that, but that inasmuch as they can get away with that and it works, then it's a testament to...

    Worst ebike ever or pure genius?

    Looks to me like it would take a lot of skill to make that work. I wouldn't try it.

    Federal subsidies for ebikes lost in new budget

    Good point about lawn care equipment, but for me, the subsidy should be for domestic production facilities. Be it batteries, complete bicycles, motors, controllers, the US could be producing some of that stuff. When you give people more money to buy things that are in limited supply, their...

    Weirdest E-Bike

    If it were a bike, it would be at least a strong contender.

    Whats your best wh/distance?

    I wonder if there's a computational error here, or incorrect assumptions about battery capacity, something like that. 15-20mph with pedaling ... you can see on the motor simulator, you're supposed to be able to expect 27wh/m WOT at 26mph. Cut back to 2/3 throttle, 18mph, and cut that in half...

    I want to make my first EBike conversion! Need advices, please

    I use a direct drive, too, and it's a simple, very trouble free option. But for someone looking for a more ordinary bicycling experience, I think I would have to consider a geared hub, rather than direct drive. I think it's a little more efficient at lower speeds, but the main thing is that it...

    Inclusion with transportation costs - US government grants?

    Ebike conversion is a on a trajectory to collide with government. I'm optimistic that it won't actually collide in my lifetime, either because no one really cares that much or because the current factors change in some way. But currently, most states pick up on ebike regulations promoted by...

    Good controller with a display?

    OK, so there I see for example "KT 9 MOSFETS Controller(06B121)" No mention there of regenerative braking, so there isn't any? cruise control, so not supported USB parameter setting interface, there isn't one? multiple throttle/speed ratios etc. You can download manuals, but they all look...

    Good controller with a display?

    Is there a more or less authoritative web site for the KT controllers? Models, features etc.

    My recumbent cargo bike

    I'm reminded of "The Straight Story" movie, old guy gets his riding lawnmower on the road to visit his brother, has many adventures. The diagram has the rider somewhat farther forward than I like, but that's just a baseless intuition. If I remember right, your rig goes pretty far out back...

    Industry worried about fed regulations, selling “overpowered” bikes

    Hm, some elements of a tease here. I mean, like some of this is to encourage industry people to drop some money on these consultants to get the complete story. For example "... and here's my card", she said. I don't know. Like I said, one way out is to bite the bullet and accept that your...

    My voltmeter/throttle shows voltage when I pedal without battery, does this mean I could have regen?

    Really? Here I'd been imagining that geared hubs coast freely, since almost all of them have freewheels. A little envious as my direct drive with regen creates a small but noticeable core loss drag.

    Industry worried about fed regulations, selling “overpowered” bikes

    I can't see the article, but sure, if I were making electric bicycles for the American market, there'd be a little concern that things would settle down to a nation-wide standard limit, where my stuff would be on the wrong side of that. Production would have to come to a halt, current inventory...

    52V battery now 20V - dead?

    Yeah, the battery is fine. I get 50.2V at the terminals, and individual cells check out at 3.1V. All the connections look good to me, nothing loose or broken. No signs of heat. Battery out from BMS remains 21V. I'm stumped so far. Supposing the BMS shut down to 21V after detecting a low...

    52V battery now 20V - dead?

    If the red wire goes to a cell, yes - but I don't see that. I think I found the 16th wire - the last cell on the other end has a big black wire that connects to the other end of the BMS board, soldered at the corner. This does seem to add up to the 16 x 3.1V full battery with all cells...

    52V battery now 20V - dead?

    Ha, I imagined there'd be A123 cells in there, or something of that nature. The BMS has a row of wires out to the cells, and testing those I get a sequence from the 0 to ca. 48V, incrementing by ca 3V each connecting point. Starting from the pin that's towards the bottom here. So if...

    52V battery now 20V - dead?

    And those would be relatively few, I think? The problem initially, anyway, was system wide outage, so "ignition" power to controller That stuff all looks good to me, but apparently there's something wrong in there. Anderson Powerpole connectors to the battery. The problem started after I...

    52V battery now 20V - dead?

    My LiFePO4 battery abruptly lost charge, on the road yesterday. When I got back it was 20V or so, and the charger won't light up and start charging. Dead? The long story: I've recently had connection problems, such that everything drops - CA3, throttle etc. Sometimes comes back by itself...

    Terrain Control alternate to PAS/Torque control

    There was a saying back in the day ... "I had this problem, and I used threads to solve it. Now I have two problems!" Python is still not able to run threads in parallel, I think? There's sort of an advantage to this limitation, that the potential for race conditions etc. is at least...
