    Fat Bike vs (Hardtail)-MTB

    Hi all, I'd like to build the most universal ebike possible. My ebike journey started with a fully which I kinda regret today. The idea was that I can ride it on the road with (mostly) disabled suspension and then go offroad with full suspension. But here's the thing: I'm driving on paved roads...

    Max. safe discharge current for unknown cells (18650 6P)

    Hi all, today I got a Phaserunner because my BBSHD stock controller died (again). Without doubt I want to increase the power now that I got this powerful controller. The only way to do this (without buying a new battery) is to set up the max. current to be drawn from the pack. Well, I have a...

    BBSHD ensuring controller longevity with PAS

    Hi all, after my first Controller fried after just two month with stock settings I am a bit scared now and wanted to ask for advice. From my understanding I need to make sure the motor is spinning preferably fast. This isn't an issue when using the throttle but when I want to pedal I need a...

    Is it possible to overcharge a batterypack due to defective BMS?

    Hi all, today I drove through a lot of rain. Suddenly the display shut of and the motor stopped working. I thought the battery might have got some water so I opened the hailong case and it was indeed wet. Well, I dried it, cleaned it and re-connected it but still the display won't work. The...

    BBSHD speed sensor torn off

    Hello! today was my first ride with my new BBSHD. Somehow I managed to "loose" my speed sensor. In fact it's torn off (as you can see in the picture attached). Well, how can I replace it? I think just a new speed sensor won't help, right? I think I'd need to replace the cable also. But how...
