    "Copper/nickel sandwich" buses for series connections

    My limited understanding was if the controller is asking 40A from a battery pack made of 18650-25R (2.5Ah, 20A-max) with no BMS (or a BMS that is 45A or 50A, meaning the BMS factor is irrelevant in this case study) then a pack made of 10S2P is 36V-nom (42V-max) 5Ah 40A-max you are pulling 20A...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Your motor must have been built on a Friday near closing time. Is the added pcb board new or have they been doing that for awhile? I literally can not remember if mine had a pcb board, but I think I would have remember if it did. I use an unsensored controller so I only use phase wires and...

    How many volts do you run on your daily driver ebike, emoped or eBSM?

    I have 14S 52V Grintech 14.5Ah hard case with 40A that I bought with a Satiator thats charged to 56V at low amps when I get home then 58.80V charged at high amps before I leave the next day. I also have 10S 36V Ryobi battery thats only ever charged to 40.40V not 42V. I use both batteries when...

    Move to XenForo software

    I am in no rush for the cross over to the new format as I am set in my ways, its just human nature but I will learn like everything in life. I am curious as to when the switch might happen? Thanks for putting in so much work for a time consuming task, I am not so much computer oriented when it...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    OK, but even the RH spoke flange is not uniform not like traditional hub motor designs for the flanges. Whats the affect of saving that kind of weight on the rotational assembly without jeopardizing hub motor strength where its crucial at the spoke flange. I'm sure its been tested and is more...

    Leaf / leafmotor / leafbike high efficiency 1500w motor

    Not to mention 27H vs 35H, better heat dissipation, not sure if the Grintech's motor is more efficient then Leafs. The Leafs 35H is better heat dissipation apple-to-apple, meaning if both using FF but its not really an apples to apples comparison for the different physical size, more metal, more...

    Absolutely crazy aint it The government of any country cant do much right can they. But please, dont build that nuke generator in my back yard ;) My utilities just went up quite a bit, our heat is gas furnace with a gas insert fireplace on each of the 2 levels but water and waste is now...

    Nick's Black eTownie

    Don't worry so much about the dropouts, they handled my hub motor, 2kw just fine with mxus 3kw (heavy heavy heavy motor) However I wasn't doing jumps or getting air, just the occasional curb action is all. Its the holes in the frame for the cable routing you have to be concerned about. My blue...

    OCC Stingray hotrod

    I dig the build, but 72V 65A on a MY1020 motor, a quick google on my part comes up with 500W for that motor, but yours is a Vevor MY1020 so different then https://www.electricscooterparts.com/motors-my1020.html which are Unite. I also never seen v-brakes on any wide rim, but you cant beat the...

    Cured my wife's anxiety and my depression with nutritional supplements.

    Whats your thoughts on Nicotinamide Adenine Dinucleotide (N.A.D.) ? https://www.webmd.com/vitamins/ai/ingredientmono-1016/nadh edit - After reading Nep's response I had no clue it was related to Nicotine, a little back story - I was listening to Tim Pool as a guest talking about his Keto...

    Ebike riding with a speaker and lots and lots of lights?

    I ran into a beer 12 x seat bicycle thing in a neighborhood next to the down core, where the rich folk live and the yuppies live and hangout in Inglewood (unlike Cali's) It was a real loud annoyance and it blocked traffic, seen it 2 times. Last was at a keto cafe and it really pissed me off. I...

    Ebike riding with a speaker and lots and lots of lights?

    A horn is a great idea, maybe have two or three modes. Normal noise level, and more and more noise level ;) I have a handlebar bell and I make noise (whistling sometimes) The fat bike made a lot more noise with its 26x4 tires then my 26x2 and 700x45 setup does. I notice a difference with road...

    My econo-e-bike

    Always best to measure the rim yourself. Chain Reaction has a size down to 182, 184, 186, 188, 192 on up if that meets your requirements. https://www.chainreactioncycles.com/spokes I've played around trying to find the right ERD of a rim to fit those sizes and playing around with the spoke...

    Ebike riding with a speaker and lots and lots of lights?

    What are your thoughts on those people who ride their ebikes with radio or music just loud enough, not blastingly loud? The other aspect is about lights, crazy light shows, modest light shows or subtlety led colors or very traditional lights. Flashing or solid, blinding lights or what. I ran...

    Which electric bike should I buy?

    From the vagueness of the inquiring post And I hope I am wrong Its most likely a long game (no from the get go "posts") setup post be a 2nd post to a link where they happened to buy their "first" ebike and just happened to love it so much and just want to post a positive review of some rando...

    My econo-e-bike

    Some specifications on rim websites can be wrong, I remember emailing Grin about a rim website I found for a rim with a differing ERD listing, but Grintech actually measures theirs so I trusted them and ordered spokes for Grintechs ERD #. It could have been the same rim with an outright lie on...

    Taking steep hills with a hub motor

    Get a thermistor installed in the hub motor and have a controller that can read it and save your motor. I should have done that with my mxus 45H 3kw hub motor, and it would have been saved from melting. That hub motor was heavy a.f. and I never used it to its potential, I actually used it quite...

    How do you feel about your state's moped laws?

    Exactly :thumb: So what speeds are you riding and is it always on the road in the middle of the right lane or riding the curb in the right lane or you rocking the middle lanes when not about to turn? All your ebikes are bicycles right? Not enduro/stealth suitcase frames. I can't remember...

    Are these wheels not laced properly?

    Front hubs dont have the load ...... unless you have a cargo bike with a heavy load in the front. On a regular bike, 380lbs of human plus ebike stuff, rear hub I had lots of problems. Problem after problem Same setup with 135mm rear hub but now front hub (literally the same laced hub on a fat...

    Damn rear derailleurs

    MicroSHIFT Acolyte - I'm done going in half ass, time to go with having good components, at a good value, set up the right way and doing things right and the Acolyte seems to be a solid choice. When I was looking for components for the gearing I want on my ebike, the Mezzo and R8 came up a lot...

    Optimal Gearing + Cycle Computer Cadence Measuring

    Last Edited (Friday, November 26, 2021) with remarks added to the end of the post and I cleaned up the original post. Looking about for one of my random single geared freewheels and still havent found it. I have about 3 or 4, maybe even 5 large tote boxes of stuff, some neatly organized with...

    Optimal Gearing + Cycle Computer Cadence Measuring

    Figuring out proper gearing for my ebike for my preferred cadence I have no clue what my riding speeds are but my 48-14 gearing seems to be close for my cadence (no clue but guessing its 65-70rpm) and cruising speed I like to ride, literally no clue on the actual speed I like to cruise at. 301...

    Cyclist spits at me and makes a buzzing noise !

    Who cares, I probably passed him a few times (without pedaling) in the past is what I am thinking. But that fella was a fast lycra roadie cyclist who I believe was wearing shorts on a day that was cool, +5C with a windchill which is even more when riding. The thing is, about 25-33% of the...
