Welcome to the community! Glad to hear you are enjoying your E-Bikes! On a side note, I'd recommend doing some research on the different model years of the Sprinter for their 'Limp Mode' issue. It's an expensive fix if it happens. I love Sprinters, but would hate to see that happen to anyone :)

The advertised range is a hard variable to tackle since there are so many factors in determining range. A formula I would use is: Wh / W ConΦ @ v = h = mi. Battery Watt-Hour / Watt Consistency at speed = hours = miles. Example for a 48V 16Ah Battery: 768Wh / 750W @ 20mph = 1.02 or 1 hour = 20...

I'm glad you got it resolved! It can be challenging for us to diagnose problems over text without physically being able to work on the bike. Sorry for the miss diagnoses on the 24 error, I was assuming it was following a common code pattern, but very well could have meant something different...

Hello Milton, here is a quick and easy motor / controller phase test you can do at home: Please give this a test and let me know what you find, just keep in mind, this is only for testing mosfet (phase) shorts, so I cannot guarantee it will find anything: If you elevate the rear wheel and spin...

It's good to keep in mind that given the tools and skill level, every lock can be bypassed. I would recommending finding a few highly rated lock and seeing if the LockSmithing Lawyer on YouTube has conducted tests on them. I know he has tested the Abus Bordo 6500 (which some of my coworkers...

Hello again Jack, I miss spoke on the Error Code 24, a phase abnormality would be for a Mid-Drive motor, for a hub drive however it would be a hall sensor fault. In this case, you can test this similarly. If you rotate the rear wheel backwards very slowly (whether by elevating and moving it by...

I would also conduct my tests along with what JES2020 has pointed out, I've delt with Bafang systems for 6 years coming up with diagnosing tricks for them, so I would be curious to what you would find. Let us know if anything comes up! :)

Let me know what happens with that test, and also let me know if you feel an abnormal amount of resistance when spinning that rear wheel backwards (like it takes quite some force to move) because that may indicate something else entirely. I forgot to mention, for the hall sensor testing trick...

Hello! Sorry to hear about your problem.. This almost sounds like a faulty hall sensor, or battery output (some kind of BMS fault). My suspicions are with the hall sensor though. This is because if there is a single bad hall sensor (normally 3 in 3 phase motors); the motor will not turn when...

That is pretty common for manual diagnosing from manufactures. More than likely it's a communication fault, these are generally fixed by replacing the display screen. Sometimes with communication errors (if a display swap doesn't fix it) the next step would be to replace the motor controller...

Hello! I an usually not a good salesman but I can try to offer a few pointers. To your interest in Mid-Drives, I would agree that those would be a great option, not necessarily that they are better than hub drives, however in my line of work, I found they handle heavy loads better. This is...

Hello Jim, is this code propagating on a unit with a hub drive motor or a mid drive motor? And do you happen to know the brand of motor that is on your unit? For hub drives, generally speaking, an E10 will be a communication fault, on mid drives this is normally a temperature protection code.

Hello Jack! Concerning your Error 24 (which should be a phase abnormality) Could you try this out: If you elevate the rear wheel and spin the rear wheel backwards by hand, can you feel an abnormal amount of resistance? I.e. more resistance than the drivetrain, if the motor or controller is...

Hello Commodore1962, regarding the noise question, it would be hard to tell from typing if the noise is isolated to the motor, brakes or to the drivetrain of the unit. What kind of noise are you hearing? In regards to the power with 15% and power mode 5. There is a difference in wattage output...

Hello cardiobiker! Could you perform a diagnosis trick that I describe? Before purchasing a new motor, it will be worth to make sure that is the issue. With the unit turned off, If you elevate the rear wheel and spin the motor backwards by hand, can you feel an abnormal amount of resistance...

No problem at all! It has been about a year since I've worked with the DCP-18's directly, so my memory is kind of foggy. Apologies for that! It could be on those that you would need the Bafang Besst programmer and log in in order to fiddle with the parameters. I know the DCP-10 is slightly...

Hello! This isn't necessarily a sign of a future motor failure, as failures with motors are generally a burn out on 1, 2, or all 3 phases, or a hall effect sensor failure. Single phase burn outs will dramatically decrease power if not ceasing power all together, and normally you can smell them...

Hello, the clunking feeling could be one of 3 things off the top of my head. One, the most likely culprit, is the derailleur adjustment or more likely the derailleur hanger is bent ever so slightly (the part that holds the derailleur to the frame). A couple other things that can effect this, is...

Hello, it could be that the display is reading inaccurately or one of the sizing settings is off. If this is a Bafang DCP 18 Color Display I would recommend going through the programed settings to verify if the wheel diameter and battery voltage were set right for the unit you have. Hope that...

They do indeed look like decent units! I am unfamiliar with them, so I wouldn't be able to give an honest opinion. I would recommend one last thing though before purchasing a unit (from whomever you end up choosing), that you contact your local bike / ebike shops to make sure that they will...
