Hey @LimboJim, To further Gionnirocket's post, here's my Cusmade 1103A and an Amass XT90 sharing the same charger via an Anderson PowerPole PP45.

Anyone good at repairing electronics could splice that back together. Or you can buy a replacement here: https://www.greenbikekit.com/dpc18-display-for-bafang-motors.html Choose the "UART, Eco and Sport mode(0-5 levels PAS,default LCD for M620)" version.

Yikes. The one way roller bearing will likely shift again because the helical cut gears cause side loading. Next time, push out the bearing, thoroughly degrease the surfaces and reassemble with Loctite sleeve retainer. I think the same thing happened with the rotor shaft pulling out of the...

Hi Zoomy, Here are my instructions for making an X1 cable: Post in thread 'Archon X1 Programming Thread (questions and experiences) If you can't build it, or find someone to build it, I can build one and sell it on eBay for you. The price would be reasonable. Lode Crommen (Daxxie) in Belgium...

Hi Invader, I thought I saw you asking about using the Besst app a while ago but I couldn't find your post. I recently learned about an open source Bafang app that can perform calibration. https://github.com/andrey-pr/OpenBafangTool/releases I hope it's useful for you.

The problem sounds mechanical. Like the motor is overcoming a great amount of friction and overheating. The controller is known to reduce power when overheating. California Ebike may be willing service the Bafang components of the motor.

Lode Crommen / Daxxie in Belgium. Seems to have a connection with the X1 designer Krasnodar.

Check if there is a broken pin on the bike side of the display connector. Strange things happen with a missing ground connection. I'm struggling to think of how it can display a high voltage but a correct percentage, though.

Check if there's a factory reset option in the advanced menu. It might sort out this glitch.

That really seems like a 52V battery on a 52V display. Even if you charged a 48V battery with a 52V charger, the BMS should never have let the voltage get that high.

You would see these percentages for a fully charged 48V battery if your display was set to 52V

You can hear the difference here.

It's a Cusmade 1103B but there is still no retail source for these. Maybe they will sell directly to you?

The build quality of the U4000 and U6000 shifters and derailleurs is lackluster. Stick with U8000 and Deore linkglide components if you're used to perfect shifting. https://www.emtbforums.com/threads/shimano-cues-u6000.36038/

I tried out the new quieter gears from Green Bike Kit. My results are over here: https://forums.electricbikereview.com/threads/m620-new-quieter-gear-comparison.54786/ Pulling the rotor is like pulling teeth - the magnets are super strong. Calibrating the rotor with the fully cracked X1 Tool was...
