If I lived near you I would drop it up to asap bub we have a lot of water between us

That sounds very hopeful but I hope I can put it back together again

Ok thanks for your help. I will try to get the bike bake and dissassemble it and send photos or video to you

Yes correct front wheel hub drive . Where or what part do I search for to replace this damaged Cadence Sensor. I have emailed the company where I bought the bike years ago and I am still waiting on a reply.

Thanks for your reply and sorry for the confusion. When it comes to bikes I am not so technical. The bike is in the repair shop so I don't have it now. The 2 photos are from the repair guy. I ordered a Left side 12 Magnet E-Bike Pedal Assist Cadence Sensor Kt-D12 to see if that would be the solution. The problem is that this goes outside the bottom bracket. My bike’s sensor is built into the bottom casing so it all has to be taken apart to fit it. Below is a photo of my bike bottom axle casing. I hope it will shed more light on the problem.

The bike uses an integrated bottom bracket (BB) sensor (the sensor is built into the pedal axle housing, not an external magnetic disc) Obviousy not used any more in newer ebikes. The internal sensor housing is cracked. The internal "magnetoelastic" wire running along the edge is snapped, causing a dead circuit. Would like To find a "New Old Stock" replacement or a modern pin-compatible alternative.

Thanks for you quick response, I will have a look on Ebay. I am not so knowledgeable about ebikes so still not so clear but it is a start.

My wife cycles the Momentum Electric Model T e-bike over 10 years without an issue. Last year got the batteries renewed. I brough it to the bike repair shop after it stopped working last week. Seems the crank sensor is brocken and bike shop can get parts from their suppliers photos attached. The problem is where can I get the crank sensor parts to fix it? Any advice welcome!
