    BBS01 Controller Upgrade 36V to 48V

    I can confirm that my BBS01 is still going very well after the upgrade to 48V at around 5,000km on the clock. It is now approaching 23,000km without any mechanical issues. My original chainring (44T) is quite worn and dropping the chain frequently, so I am in the process of replacing that and...

    BBS01 Controller Upgrade 36V to 48V

    Sannder, my upgraded motor is BBS01 Version A. Still running very well after the upgrade with no issues so far. I have now done just shy of 8000km in total with the motor of which about 3000km since the upgrade.

    BBS01 Controller Upgrade 36V to 48V

    Hey Bombus, 65kph sounds insane on a bike. I have the stock 44t chain ring and 11-32t 8speed rear sprocket. I've had mine up to 46kph in 7th gear (13t), so reckon 50-55 in 8th (11t) is possible. @Mündawg, yes voltage is the way to go, but as you said, temperature can be a problem. I don't...

    BBS01 Controller Upgrade 36V to 48V

    Just a quick report back on my original post. I did exactly what the post said. Ordered a 48v controller and swapped out the 36v controller. I then built a small 4s4p battery (16.8v fully charged) which I run in series with my 36v (42v fully charged) battery. This gives me a 52v (58.8v fully...

    How To, 50A BBSHD Controller Mod

    Hi Ebikes4Real, I was just wondering if there is any way of modifying the controller to use a higher voltage battery rather than increasing the current. 72V at 30A should be really good.

    BBS01 Controller Upgrade 36V to 48V

    Hey Lurkin, You are probably right, it runs very well and reliably at the moment. I have done 4000km trouble free on it. Maybe just invest time and money on a new project (New bike with BBSHD and 52V battery) Now to find the right donor bike ...

    BBS01 Controller Upgrade 36V to 48V

    I achieve the speeds in the 80 rpm column exactly in all 8 gears. So 48/36 = 1.333 1.333 * 80 = 106 rpm So theoretically I should be able to get to the speeds in the 105rpm column? Not bad if this is how it works out.

    BBS01 Controller Upgrade 36V to 48V

    Thanks Amberwolf, What you are saying makes a lot of sense. The motor currently spins to max 80 rpm, do you think it will go up significantly with an increase in voltage?

    BBS01 Controller Upgrade 36V to 48V

    I've seen this question asked many times, but have not seen a definitive answer, so maybe someone here can help. Can I replace my BBS01 350W 18A 36V controller with a 48V controller, limit the amps to 18A and so get some more power from my motor? I know that a 48V version of the 350W BBS01...
