Firstly, i do not advise anyone to replicate what i have done for reasons i will explain later.
As my Cyclamatic Power Plus has run out of warranty, i decided to have a tinker to see if i could improve upon the average performance.
After reading up on controller shunt mods, i opened her up and carried out the procedure.
Basically, i soldered a small piece of coat hanger wire across the existing single shunt.
This was easy enough to do as the circuit board slides out of the casing and the shunt terminations are easy to access.
After a test run of about 2 miles, here are the pros and cons of carrying out the mod:
Pros
1) A very noticable increase in pulling power (torque) from standstill.
2) Hill climbing ability greatly inproved.
Cons
1) If still under warranty, will most definitely void it.
2) Motor sound much louder on part throttle. Ok on full. No more stealth.
3) Haven't done a distance test, but very likely to decrease total distance due to drawing more amps.
4) Probably fry the battery a lot quicker than standard setup.
5) No idea how long controller will last with modified setup.
As you can see, the cons outweigh the pros, but definitely something worth doing if you can put up with the increased noise but want extra pulling power for the hills.
