Hi everyone.
I have a Samebike MY-SM26 ebike, and I recently had my battery+controller stolen.
The original sm26 (custom-made) controller is currently out of stock, so I purchased this one:
https://www.aliexpress.com/item/32967236787.html 48V Kit A.
I also purchased this battery: https://www.ebay.co.uk/itm/164793096562.
Upon connecting everything, I’m getting error E10, which means that my S830 LCD display does not properly communicate with the controller. I’m aware of that, and the listing on Aliexpress makes that clear. I have tried using a compatible KT display with its compatible 1to4 Julet cable, and the E10 disappears.
However, all issues outlined below, occur with both setups (original and KT compatible):
PAS works fine, and I can ride the bike with PAS with no issues.
Walk mode also works fine.
Unfortunately, (full) throttle works intermittently. I can (full) throttle the bike for 2-3 secs and then the motor stops. Every time I press the throttle switch (on full), the motor spins for 2-3 secs and then stops.
If I press the throttle switch gently the motor spins with no issues, if I press more to increase the speed, the motor stops. So, I can only throttle the bike on low speed.
I’m really struggling to figure out what is wrong, and what needs to be replaced or fixed.
Any help would be greatly appreciated.
Some characteristics of the equipment can be found below.
Thank you.
