    Sabvoton/Risunmotor controller programming help!

    So it appears to be fixed! At least 99 percent of the shaking/judder at start. I apparently got a proper combination, plus decreasing the "Reverse Speed limit (%)" under function tab to 5 or 10. Weird! I'll take it for a longer drive and report back. I've read various things, in layman's...

    Sabvoton/Risunmotor controller programming help!

    Also to add, when I just pedal with bike on PAS doesn't engage. Once I give throttle and am pedalling, then pas continues to work. With tire in air and me hand spinning crank arm, PAS engages.

    Sabvoton/Risunmotor controller programming help!

    Sabvoton/Risunmotor controller programming help!

    So unfortunately it seems the settings didn't help. Sometimes it doesn't happen and then it does. If I roll the throttle slowly, I can avoid it happening. I changed min throttle voltage to 1.00 and it seemed to help a bit. Since I have Flux weakning off, should the red circle display enabled...

    MJ1 vs 30Q for my needs?

    Wow that threw a curveballs in my plans! I had reiterated my amp requirements to EM3EV and they said the PF cell would work. Now reading the specs your provided, doesn't seem feasible. I don't mind spending the money, as I understand a good battery is paramount. Moreso to me due to performance...

    MJ1 vs 30Q for my needs?

    Guys thank you very much for the education and informative replies! After much more research, back and forth, I was hoping for a Luna battery but they are still out of stock. I have decided on the EM3EV 52V (14S7P) Hard Case Ebike Battery Pack 20ah using PF cells. I live in the actual city...

    Wiring 1T4 or 1T5 cable

    Hello, My current ebike is using a 1T5 Julet, maybe called Eb-BUS connector. I notice 1T4 is more popular. I cannot find any female 9 pin connectors to go with the 1T5. It basically puts the headlight, 2 brake connectors, display and throttle through this cable. Does anyone know the wiring...

    Need controller help for Rize Blade and identify wiring

    Can someone please help ID these 2 cables. The first one appears to be a 9 pin breakout or wiring harness. I've found Bafang 1T4, but cannot find any of the 9 pins I have. Then this is the power cord, any links to buy? Can it handle a 52V battery or should I convert it to XT90s?
