    CYC PHOTON

    This guys trick has been working reliably for me with my photon. Of course a proper Isis crank puller is more reliable still.

    Does this imaginary voltmeter that I want exist?

    Well I ended up in a rabbit hole of my own. You need sniped me! https://electronics.stackexchange.com/questions/661989/dc-voltage-48-58-v-to-0-10-v-scaling I found this, it's basically what you want to do but with a lower battery voltage so the answers should hopefully be applicable. Of course...

    Does this imaginary voltmeter that I want exist?

    Well analog speedometers are made with stepper motors and definitely wouldn't have any issues with vibration. I just kind of assumed that a spring based voltmeter would have issues but ultimately my theoretical musings is trumped by your personal experience with your ammeter. That's the exact...

    Does this imaginary voltmeter that I want exist?

    I've thought about this a bit before, some things I thought of. - vibration could be a big problem for an analog meter, likely you would be better off with a stepper motor and a needle like car speedometers use, they are cheap and easily available, but of course add big time complexity because...

    I guess I need to make 72v 35ah battery pack

    No it doesn't bypass the BMS protection when charging. It's more than just connecting the charge wires to the discharge port, the circuitry inside a common port BMS is different such that the BMS is able to shut down current in both directions on it's one output/input. Whereas in a separate port...

    Hi, I am trying to buy a bbshd and I already have a CA3 with 8 ping connector. Can i use the stock bbshd stock controller with my CA?

    Not in a simple plug and play way. It will require some knowledge and rewiring connectors etc along with changing corresponding settings in the CA. You'll need to add an external shunt is one thing I can think of. Then if you want all the throttle stuff you'll need to wire up the throttle...

    I guess I need to make 72v 35ah battery pack

    I'm not currently set up for regen, though I hope to be someday. When I do, I want both protection in the controller and the BMS. Plus I only charge to 80% typically. I definitely lean on the over cautious side though. If I could only pick one of those three options (while I won't preach needing...

    I guess I need to make 72v 35ah battery pack

    Common port, charging and discharging are done on the same port on the BMS. Separate port, there are two ports, one for charging, one for discharging. Situations when common port is best include using regen and when parallel connecting two batteries as this allows the BMS to still be able to...

    Mini Hiryuu - Mid power ebike

    Thanks for the info! I realized shortly after I posted that I don't need to worry though, forgot for a sec that I'm local to Grin so bringing my own rim isn't an issue :P Learned a bit more about rim brakes from your post though, this is my first bike with them since I was a kid and never...

    Mini Hiryuu - Mid power ebike

    As someone who wants to order a motor from them (when I can budget it) and has V brakes I'm confused. All the rims I've looked at on the site say rim brake compatible in the specifications. Am I missing something?

    'lightest.bike' 1.7kg 1000w mid drive

    While I don't think it has that now, the photon has a VESC based controller meaning it's open source and not difficult to get custom firmware onto. So in theory virtually any control scheme is possible. The hardest part is waiting for someone to write the firmware though.

    Open-source connected e-bike platform

    You presumably can't use the pedal sensor without your custom vesc or can the pedal sensor be used with any vesc? (which I assume is a torque sensor though it doesn't explicitly say, only says "more natural pedal assistance") Also it feels like an entirely unrelated product to the GPS tracking...

    CYC PHOTON

    I didn't bother with a heat gun or hair dryer or anything. I just shoved a slotted screwdriver in there and pried. It came off pretty easily. I couldn't do nearly as neat a job applying the replacement gasket (also I had to buy some stuff myself cause they didn't send any) but it's more...

    Help with torque arm install on rear hub build

    I would not do the cable side. Hollowing out the axle for the cable significantly weakens it. I think I remember reading somewhere the hollowed axle side is half the strength versus non hollowed. Don't have the time to dig for the thread unfortunately.

    Does the rear have the same problem? Maybe there's a reason you've ruled out rear that I don't know but it seems to me it would probably be a lot easier based on pictures I googled of the rear dropouts.

    Bump since the motor is all fixed up now and working and running great. Also lowered price.

    'lightest.bike' 1.7kg 1000w mid drive

    Perhaps they only measure torque on the opposite pedal side without the chainring so they don't get the motor contribution? Pedal Assist Systems - Learn This page mentions sensors that don't pick up both pedal torques.

    Need ideas for upgrading from a pedal-assist to a pedal-assist + torque assist.

    Main9 Superharness Doesn't it only work with the phaserunner/baserunner controllers though?

    Dutch police found a way to test e-bike power on the side of the road

    Is it actually a dyno for measuring power? I thought it was just measuring speed so they could get around spoofed speedometers. If so are they going to impound all the Bosch and Shimano motors that routinely go over 250w? If so Imma get some popcorn this s***'s going to be hilarious.🍿(or maybe...

    Dutch police found a way to test e-bike power on the side of the road

    I'm in favour of stopping speeding ebikes but if only they had some sort of magical device they could point at someone and it would tell them how fast the person was going. That way they could pull over the people who are speeding instead of the people who are capable of speeding. Of course...

    A piece of Australian ebike history

    I'm glad to hear that! Something that unique and interesting deserves to either be proudly ridden or proudly displayed. I assume the batteries go under the red cover? Pretty sleek integration even if the design itself is bizzare. No rear brake that I can tell?

    A recumbent build

    Not going head over the handlebars is a definite plus for me. I've got two mostly fake teeth from exactly that (and I feel like I got off lucky with just that, it didn't even hurt) If I had to guess as to why uprights won out is the "recumbents can't climb" idea. I've definitely noticed not...

    $1000 CAD CYC Photon

    Edit: All is fixed now. Motor is working great. Okay I can see why I got no bites now. I've got it back on the bike and the torque sensor isn't responding now. Took it all apart and rechecked the connections. Still nothing. At least the stuttering has stopped though. I'm attempting to get a...

    A recumbent build

    Hehe. Thanks for all the advice. For now I remembered my jacket that I'm always wearing has zip pockets. It's also thankfully only my phone and flashlight I need to transfer since my pants already have a small zippered pocket for my wallet (so far doesn't seem to wiggle loose even slightly but...
