    BBSHD Cargo bike Programming

    I'm new to electric motors, and am looking to configure my BBSHD for cargo bike use.

    I live in a hilly city, and the main use of the motor is to get up the hills when laden down with up to 100kg of cargo, as well as getting started on the flat with big loads. I'm happy to put in some effort and would rather have a pedal assist, than a full-on electric motorbike. I generally pedal with a fast cadence (90-100 rpm) on the flat as well as climbing (80-90 rpm).

    Let me know your advice please!

    oh, and I'm not using brake cut-offs or a gear sensor (with a rear derailleur).

    At the moment i tend to stop pedalling then shift, which hasn't caused any issues yet, but a soft introduction of power, as well as a immediate cut-off when I stop pedalling would be best, I think.

      Get at least one of the brake handles so you can control PAS cutoff instantly. I don't use a gear sensor but use both brake lever cut-offs. I leave a little slack in my front brake (I still use cable brakes) so I can flutter it to cut off the assist during shifting without actually braking.

      I don't know that programming for a cargo bike is that different other than to maybe bring on the assist sooner and harder.

        Gear sensors are awesome, great bang-for-buck and not only do they do their job very well there's zero downside

        Programming is another animal and what is "best" for on, not for someone else adn what works for one bike, not so good for another

        I would get a cable or other way to program, read the threads on programming and begin experimenting

        Having said that I prefer "unlimited" PAS setups that set the speed limits 100% across the board and a current profile that starts very low and ramps up geometrically vs. a linear progression - linear is what most factory tunes are and I never understood that at all

          I had problems with the gear sensor - it did not work well - maybe it is better to put it on the steering wheel right behind the handles - then it does not dust and does not get dirty. So I put on instead of it - a device that is similar to a thumb grip, but instead of a grip it has a bell switch - like a doorbell at the front door of the house. I used the plug and cable from the wire from the brake switch. Now I have an instant switch under my left thumb and I press it every time I change gear. Works fairly smoothly. It can also be used when braking sharply - a matter of habit, at least it does its job decently.

            Mine got sticky after initial install so I opened it up, cleaned and lubed the little wheel pivot took some emery cloth to the cable and little wheel groove and put some silicone tape over the part of the sensor where the cable enters and exits... only once in many thousands of mile after that did I have to clean it and that was all of a five minute task... mine is mounted just above the motor at the seat tube top tube junction... I ride in a very dusty environment...

            YMMV
        Working...
