The BBS02B is the newest improved version. I am thinking I will set the max amperage very low on certain levels. I would think that the sensor should be on my 26 drive wheel to reflect accurate speed readouts. Definitely not the same as when at 50V etc.. Not sure where to look in the settings to adjust. It is effectively the thing you would do when using the throttle, the motor will do all the work. Having more drag on an e-bike is normal. Thanks for letting me know. If not, try to change them to these values. I think you are not reaching higher speeds because of your gearing and wheel size. So if you want to know your actual battery percentage, you should stand still and wait a bit for the voltage sack to disappear. I understand that the current will be set at 18 amps. Thanks in advance. I would contact your seller about this, if this is the case. You should match it with your bike, otherwise the speed measurement will be incorrect. P.S The egg rider might work, but I expect it not to. Can I use the settings for bss02.
