    Bottlebox battery case ? without battery

    Hi, I'm looking for a case/box to fix in the water bottle screws but I didn't find any. I made my own battery and I can make a new battery then I don't wanna buy a battery. 52 or 65cells. Where can I buy these for cheap ? (100$ the case... no) Should I make my own case ? Thank you !

    Programming the Bafang Middrive BBS01+BBS02

    Hi guys ! I really dislike the PAS and I would like to remove the display by using a small wire in order to short PL and P+. For now, when I turned on, the level 1 is set by default.(means with PAS) How to program the bbs02 in order to set the level0 (without PAS, only throttle) Thank you !

    BBS02 Chainring 52T cheapest one ?

    haha ok, actually I bought a 48T and 52T. I think it's the same problem than the guy who stays at 5th speed/gear all ride even for starting. I have a temp sensor in the motor and I have a hall sensor on one phase. I'll make my test.

    BBS02 Chainring 52T cheapest one ?

    I just wanted to not be stopped at 40-45km/h with my mountain bike (because of the gears). I'd like to go fast to 50-60km/h for some meters when I go to a road with cars (ok you maybe dont see what I mean) Thank you, indeed, i bought on em3ev since I didnt find cheaper. (it's more the shipping...

    BBS02 Chainring 52T cheapest one ?

    I think also we'll stop here, we are talking totally different situations. AND it wasnt my question at all. (I wonder who are trolling)

    BBS02 Chainring 52T cheapest one ?

    Then you said the motor in load even small cannot go faster than 85% of his max speed ? First time I hear this... Please proof. When I tried, I see this : Which confirms what I said. Where do you see the efficiency is a bit different ? I don't see any difference. In "chart options", you can...

    BBS02 Chainring 52T cheapest one ?

    I think I'll stop here, I don't want to copy paste what I said. 2) "almost at full rpm", 97% is almost, 85% is far. Now the motor's efficiency depends on the load :| 3) No one knows when the controller stop the motor, for me it's maximum speed. A bigger reduction will run better for a high...

    BBS02 Chainring 52T cheapest one ?

    Show me an efficiency curve with peak at max speed :O Even if it doesn't decrease like an ICE motor, it still decreases. Are you serious ?! You don't care about mathematics but the website you just sent me is FULL ONLY MATHEMATICS since it's a SIMULATOR. You are talking about real values...

    BBS02 Chainring 52T cheapest one ?

    Of course it's different but it's still true. It was a rhetoric question... :/ everybody learned this equation at high school :/ but we don't care at all the motor will push harder (ie torque), I just see the consumed power. I'm waiting for your explanation about the "absolutely false". What...

    Please give me the graph of the motor's power. I didn't find it. BBS02 48V 750W. Or you just guess that it's pretty similar ?

    Back bag for bike ?

    It's too big for me, I'm looking for a small bag I could remove quickly. Today I was riding the bike as usual and I climbed a small sidewalk and boum, no battery anymore : Really bad quality and no wonder this got broken ... I'll try to solder it to make it more stable and stronger !

    BBS02 Chainring 52T cheapest one ?

    Mmmmh thank you for reply me but are you sure you studied electricity/electronic/physic ? At 45km/h with 52T or 44T, the load is same... omg the load doesn't depends on the chainring..... the load depends on air, level of the road and weight on the bike, means speed and your weight. Load =...
