    Hub Motor Upgrade 500W to 750W

    I think I understand that the aliexpress battery bms will deliver what I want no problem.I just didnt understand why it would be said like that. but theres even amp room for the controllers to boost. so this is great.

    Hub Motor Upgrade 500W to 750W

    Hub Motor Upgrade 500W to 750W

    I was really liking the idea of upgrading to this battery. https://www.aliexpress.com/item/4000689290461.html but for bms is says "20Amp continuous 60±10Amp maximum" what does 60+10 mean? is that its peak ?

    Hub Motor Upgrade 500W to 750W

    any fyi ebikes.ca themselves list some ads as '190-195mm' so if 5mm variation is okay with them its okay with me.

    Hub Motor Upgrade 500W to 750W

    the bike shop will measure my dropouts before he installs my hub... if its off i will not bend my frame wtf....risk here is wasting money not damaging my bike. I guess 10 amps each controller is what its going to have to be... do you think that would make performance suffer any compared to now...

    Hub Motor Upgrade 500W to 750W

    Hub Motor Upgrade 500W to 750W

    im qualified enough to take this bitch apart if there will be some kind of labelling or a way to tell from the inside....10amps on each controller doesnt sound good to me. 20 on each does.

    Hub Motor Upgrade 500W to 750W

    okay now were talking dude. I might have to get a bigger controller box but I would want it the same style and position as my existing one. I already have this motion alarm box thing in my controller box.. works really well picks up on any vibrations on my bike anywhere and it has a key fob...

    Hub Motor Upgrade 500W to 750W

    seems like im not the only one stubborn here. i understand there will be overhead in carrying 2 motors and just using 1 at a time. but dont you think that would be worth it? why wouldnt it? I dont think the overheard would really be that bad. how much do these motors weigh? cant be that much...

    Hub Motor Upgrade 500W to 750W

    yah im aware of the risks for the controller ill replace it as she blows or later on with the battery I do understand all of that and honestly I was thinking of the idea in my head of geared rear hub and maybe a direct drive hub on the front.. and they both the same connects.. i forget what...

    Hub Motor Upgrade 500W to 750W

    I wouldnt want 2 hubs running off 1 controller.. as no hub has identical windings they will start to fight each other at higher rpms. not to mention the requirements on the controller. but what if there was like a toggle switch that made it front wheel or rear wheel drive.... now thats an...

    Hub Motor Upgrade 500W to 750W

    about seven and one - half inches is what it exactly looked like I havnt read a tape measure or a ruler since grade school lol... but its safe to say its either 190mm or 195mm... im kinda leaning towards 190mm now because if thats what about seven and one - half inches is.
