    Making new E-Bike, question about power

    26'' I could help knowing how it performs the motor. Also I'm a bit suspicious on the battery, of course for that price their not gonna be from a trusted brand. I see the company ChamRider sells more of those cheap batteries, they claim 800 life cycles and offers 6 month to 1 year warranty...

    Making new E-Bike, question about power

    I plan to move on a mountain village where this things happen a lot less, also plan to store the bike inside the house, maybe on a encapsulated corner with trusty tinfoil paper panels to avoid burning the house if the batteries decide to allahu akbar. I don't really want to pedal, I just want a...

    Cyclone freewheel replacement, what are the correct measurements?

    Hi, my cyclone 3000w freewheel start to make crank noises and catch the axis rotation when it wants to, something inside is just wasted. Even when the piece itself is not expensive, the shipping costs are ridiculous, also I've been nearly scammed by a shop that never send the piece (I open a...

    ''Disarm'' a mobile phone

    Hi, I have some old mobile phones that I never want to use again, but I find appealing the idea of turning them into small game consoles for flash, mobile games or emulators. Even if I remove the Sim card and the internal anthena (that small chip) is the phone still emiting radiation of some...

    Safe cage, Really that important?

    I made it! a home-made shitty fireproff (I hope) case. Made out of a old ATX PC case (no remaining plastic inside, all metal) whit crappy aluminium thinfoil capes to cover the holes, teoretically, if the battery decides to allahu akbar, my house are safe now.... frock at least I try it.

    Safe cage, Really that important?

    I see... maybe I can put something out of my old pc case, seeing a bunch of advised fireproof bags engulfing in flames whit just shitty small lipo's on youtube, I think I take the bet whit something of my own, at least I can feel double stupid if the case don't do the trick either.

    Safe cage, Really that important?

    I got a litium 52v 24ha pack made out of genuine panasonic GA cells, trusted vendor, whit BMS and smart charger, and I charge the thing in the house inside my room. Everyone says that a battery pack can turn into a big toxic fireball and burn you, your house, your family, your dog and your...

    Question about % and charging

    Thanks for all the advises, I get it more or less... but, even If I give the best treatment, the pack eventually gonna waste itsef as time pass because of the aging effect? Thats sad... When that happens, I hope we have portable nuclear reactors like the ones in fallout 4 that fits in power armors.

    Speed/Watts test, more speed = MUCH more watts

    I make recently a 3000w motor E-bike, whit 3 electric power adjustments, according to reads, 1rst caps the motor to 900w, 2nd 1200w or so, and 3rd goes full, burst 3400w for one second or two and stabilizes around 2400w as time pass. Well... lets test that babe, plain track, no pedestrians, all...

    Question about % and charging

    Li-on make out of panasonic GA 18650 cells. I got a smart charger, 2,5amp whit 80% 90% or 100% option. So, to go for 1000+ cycles, I must recharge when the watt metter shows less than 50v, and never let it drop below 48v, is that?

    First E-Bike, finished! (whit photo)

    Lunacycle 52v 24ha, At first I considered a 72v pack, but whit a 40amp controller I don't see that's gonna make a price/worth difference, specially when I rarely gonna need to use more output than the 1rst gear 900w. by the way, the bike is a over 1700€ preppy corratec, I just buy it used at...

    Question about % and charging

    I plan to squeeze has many charge cycles as possible of my lunacycle 52v-24ah pack. I hear that the golden rule is not to charge above 80% unless you plan a long ride or want to balance the pack, and not let them drop below 20%. So here's the question, the readings show around 50.1v, Battery...

    Encounters of the police kind

    Well... not on an e-bike but in a normal, man-powered bike. Here in Barcelona the autonomic police are a bit... douches, I'm not saying that for any particular hate toward police, I got military background and been working in security, I strongly respect the authority, but Mossos d'esquadra...

    Best Self-Defense for a Lady on an eBike?

    Make a faster e-bike... Self-defense tools that are not knife or firearms (either in trained hands) are generally crap that sells a false sense of security, they are not useless, but just a minor help, again in trained particular, in a non trianer individual, the thing just probably gonna end...
