Code 03


New Member
Anyone know of a place to get the emotion bikes worked on in Atlanta Ga that knows what they are doing. My bike was n so called shop for 2 months basically replaced everything, even new motor. 3rd time out on bike since I got it back and died at 10 miles. 03 code. I’ve checked all connections still 03 code.
Any suggestions???

Probably too late for you but others looking at this thread might be interested in my experience of this problem...

I had a similar problem with mine (Evo City) and I resolved it by removing and cleaning the torque sensor, then reinstalling it and adjusting the 2 screws to the correct torque setting (1Nm I think - I just used a cordless drill for this on it's weakest setting - number 1 - basically just a light snug tighten with a screwdriver!). I did have the problem reoccur a couple of times since and resolved it by wiping the plate between the torque sensor and the chain with a dry cloth (no need to remove wheel or sensor!). It seems to be sensitive to certain types of residue on that plate. For example, a chain wax I had tried caused it to completely stop working once a bit of it accumulated on the plate!

There's a manual here with some hit-and-miss info about repairing the torque sensor (on my bike, the 2 screws that need adjusting are unfortunately not exposed - you need to take the wheel off and the sensor out).

One more tip about that manual: there is a lot of emphasis on measuring the voltage from the torque sensor. I gave up trying to do that. I couldn't find any part of the wires exposed where a voltage reading could be taken. Also I assume, this voltage needs to be checked with battery and everything else in place, including the torque sensor itself (which seems practically impossible - maybe it's only possible with the BH diagnostic tool).
