No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric bikes from eProdigy as well as any help and solutions you know of. Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer.

Please be respectful and constructive with feedback, this is not a space for hate speech. In many cases, representatives from the company will see feedback and use it to improve their product. In the end, the goal is to enjoy riding and help each other go further and be safer.

I'm wondering why there's 1269 views on this thread and not one reply, why would someone view a thread with no posting? Anyway, I've posted and now we all have a reason the click on the thread.

Does no posts mean no one has purchased the bike or there's no issues with the bike?

My uncle has an eProdigy Magic Pro that is about 2 years old. It recently started having issues with the motor cutting out at random times. Sometimes it happens when throttling, in which case it will slowly reduce to no assistance (in a few seconds). Other times it happens when in pedal assist mode, in which case the motor cuts off immediately while pedaling. In both cases the display appears to freeze the mph readout, as the mph readout doesn't change even though the bike is slowing down. The display doesn't freeze completely, however. We noticed that the pedal assistance level readout does change during the motor cutout - we have tried to increase the pedal assistance during the motor outage to see if that fixes the problem but it doesn't. After about a minute the motor kicks back on while pedaling and everything resumes as if nothing was the matter, although the problem does repeat itself frequently (usually within another few minutes).

I'm wondering if it's a software issue because of the frozen display. Or a connection issue with the speed sensor since that's the only part of the display that appears to freeze. I reached out to eProdigy to see if they can help diagnose/fix the problem from afar and will post a follow-up here.

After a few days I got a call back from Flavio with eProdigy support. They thought it was the controller that needed to be replaced. The replacement controller was free because my uncle's eProdigy Magic Pro was still under warranty, but I had to pay $30 for shipping it to Colorado. Flavio warned me it would take 6 hours to replace but it took us *only* 5 hours and 50 minutes in total, even with the 3 instructional videos they shared with me. The controller is between the battery and the motor, and has 9 cables that need to fit through two tiny holes in the frame to connect to all of the cables from the battery (2 connections), motor, 2 brake sensors, display, speed sensor, front light, and rear light.

The only special tool you will need is a hook to fish out the 9 cables through the two tiny holes (the video shows an example of the hook). The cable with the least slack to work with is the display cable. Unfortunately the display side of the cable became lost in the downtube when it disconnected before we were able to pull it out. We had to pull it out the other side of the downtube, duct tape it to a straightened metal clothes hanger, and push it back through the downtube so we could fish it out in order to connect it to the new controller.

The whole process is not just tedious but, even in the best case scenario, also requires bending some cables out of the way in ways that could damage them. Be careful with the cable housing and connectors as they are not very durable. In the end his bike seems to be back to 100%, but the original malfunction and difficult repair path don't inspire confidence in eProdigy. I encourage eProdigy to improve the quality of their components and build an easier repair path into their ebikes.
