    Tmm4 torque sensor and phaserunner

    We've had a few customers succeed at doing that with a CA3 succesfully. It should be possible using a direct hookup to the Phaserunner's 6 pin PAS input too (assuming you also have a superharness and display). As there is no PAS signaling with a TMM4 sensor you need to use the "wheel torque...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    The MAC style motors have quite high torque with relatively narrow gears and would be the prime candidate for having at least one metal gear if offered in a freegen variant, so that will be on the roadmap for testing out for sure. Thinner laminations don't impact the torque or acceleration or...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    For sure. The good news is that at Eurobike this year there were at least a half dozen companies showing off thru-axle geared motors (up from just a couple last year), though most were still in testing/development stage and weren't yet in full production. Of those we're hoping that at least...

    What happens to freegen when teeth get stripped?

    If the gears strip then you would indeed loose the braking capability of the motor, just like you would loose forward propulsion, and you'd have to use the other brakes on the bike to come to a stop. That puts a higher onus for specifying the gear material and gear design in a freegen motor to...

    New 2017 updates to ebikes.ca motor simulator to try out

    Here are some crumbs from quite a few years ago that could shed light, which shows non linearities in the torque vs current curve maybe starting at about 60 Nm for the 9C style direct drive motors but it's really hard to extrapolate much from there...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    The EU rules for EN15194 specify that the rear brake needs to be able to apply a 220 Newton stopping force, so the actual torque that translates to depends on the wheel size: 220N on a 29" wheel is 81 Nm 220N on a 26" wheel is 72 Nm 220N on a 20" wheel is 56 Nm So even a small/medium sized...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    Thanks Epithemeus, this reply is correct on all point! In the interest of moving forward with development within an existing ecosystem, the Superharness gives us a nice platform that we have full firmware control over. Ideally it could be a firmware option for the ASI controllers and we'd have...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    I'll always be a diehard champion of the direct drive motor with all its simplicity. But it seems a larger portion of the potential ebike riders prefer a geared motor because because of the smaller size, better torque density, and freewheeling. This new option has the advantages of a geared...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    That's the hope, and in fact it's possible to have it work without even a simple brake sensor too, as long as you don't simultaneously brake and throttle at the same time. The system knows when you are using the throttle (and/or pedal assist) and in that scenario the disc rotor isn't spinning...

    New Geared Hubmotor variable-regen e-braking system that still freewheels, by ChargeBike

    Hey everyone, we've got the final cut of the explanation video about to be released shortly as a youtube premiere so that we can do a live question and answer session afterwards for all those who are curious about this concept. That's going to start today at noon pacific time, 3pm eastern time...

    Upcoming Major Changes and Updates to the ES Site

    At the time of the original forum buyback in 2011, there was a question of everyone simply jumping ship and launching a new forum with a new domain, as endless-sphere.com was simply a relic from the person who hosted the site on a domain intended for his private business. I had proposed offering...

    Upcoming Major Changes and Updates to the ES Site

    Updates to the content layout:  The structure of the various forum topics on ES doesn't always reflect how we want to have posts content organized. There are some categories that are way overused, others that are barely used, and often quite a bit of ambiguity in where a given topic should get...

    Upcoming Major Changes and Updates to the ES Site

    So here's where things get most exciting. As you're likely aware the phpBB backend on which ES is hosted is quite dated and long out of development. After a few mis-starts with other platforms, Neptronix settled on XenForo as being the best modern web software to handle the needs of our...

    Upcoming Major Changes and Updates to the ES Site

    Fortunately, the guy you know as Neptronix stepped up in a massive way, first helping out with many of the IT/hosting challenges of the site and then a large part of the management and moderation too. It's an enormous (mostly) volunteer effort to keep the site going as it has. But the...

    Upcoming Major Changes and Updates to the ES Site

    Hey everyone, I'm posting here for a long time update on the ES platform. First a quick background synopsis since there are plenty of people who weren't around for what is now ancient web history. Origins This forum was created in 2006 after the then popular V is for Voltage website...

    Cycle Analyst V3 preview and first beta release

    Glad to hear this did the trick for you! In the case of a bottom bracket torque sensor this setting doesn't do anything other than becoming the threshold to clear a torque sensor fault if the torque signal was high when the system is first powered on. But when you have a wheel torque sensor...

    Cycle Analyst V3 preview and first beta release

    Hey Ham, yeah as long as there is pedal cadence detected then the CA3 will continue outputting PAS power. But you can definitely set it up so that below a certain pedal effort the computed PAS output power falls down to zero watts. In the CA3.15 and earlier firmware, the setting PAS -> Strt...

    Cycle Analyst V3 preview and first beta release

    Ha ha I hadn't thought of that angle but what a great reply to "does it recharge when you pedal??" ! :lol: Cool, I'm interested to hear more firsthand user feedback on this and what your use case is. One important update for the regen speed limiting is a new global "Gain Adjustment" for all...

    Cycle Analyst V3 preview and first beta release

    Yeah I follow OS hardware / software projects with some interest to see when and where this approach makes sense. But the current CA3 codebase and architecture just isn't suitable for that model. It's all highly optimized 8-bit assembly and takes even a seasoned low-level firmware guy a few...

    Cycle Analyst V3 preview and first beta release

    One trick is that you can see the default for any setting with the setup utility software just be creating a "New Setup" and choose the appropriate firmware version then scroll down to the setting of interest. The values in the SU software are the same as what is flashed by default on the CA In...

    Cycle Analyst V3 preview and first beta release

    I will try to catch up and reply to many older posts from the last few pages of this thread this week. However, I first wanted to mention with an extremely sad heart that the former ES user Teklektik passed away earlier this month after a battle with cancer. People on this forum will know him...

    Cycle Analyst V3 preview and first beta release

    Ha ha sweet, and glad to hear that this has found it's some happy users and I really apologize for how long it took to get this particular behavior released. We had a branch on it back in ~2015 or so when THUN sensors were the most popular model with their single side torque sensing, and back...

    Cycle Analyst V3 preview and first beta release

    Hey everyone and sorry indeed that I haven't posted anything on this thread to keep people updated about CA development and I'm encouraged to see that there is still quite a substantial interest and following and that the CA3.2 features have been quite well received. We did a short video...
