Hi, I am in Sydney and recently picked up an Enjoy (race) to help me up these dammed hills.
I soon got fed up with the "assist" type function and thanks to this thread , decided to attempt some improvements.
So, controller removed ready for a more conventional throttle controlled set up without the torque and speed sensor interference.
But whilst i wait for the Chinese sourced controller ( YK40 @ $18.00 delivered from Ebay !!
) ...i decided to experiment a little.
A $5.00 30 amp relay from Dick Smith was hooked up direct between the battery and the motor ( using the Aprillia's 12 v tapping to operate the relay via the original key switch and "function" switch on the bars)...with a 25A fuse in for safety.
Actually i think i could also hook in the brake lever switches also if necessary, but this is a quick and dirty mod!
The result is obviously quite different ( to say the least !) , but in reality...(using a little common sense like not using power to start instantly to minimise shock loads on the gears etc)... the result is surprisingly practical !
I can now ride with or without power assist, Steep hills 10%+ can be climbed at 10-15kph with minimal pedal assist and have seen 35 -40 kph on the flat. ( and 70+kph downhill !) . Whilst the Aprilla is not exactly a "stealth" bike , it is relatively silent and i have been able to seriously worry some of the weekend licra team as they circulate Centenial Park !
. All this on the original 24v NiMhi pack.
I am now wondering what a 36v LiPo pack will give me, and at the same time really wondering if the new controller is possibly going to be a disappointment after this wacky set up.
PS;.. Gtadmin... what was your problems with the NiMhi pack ?? ...mine seems ok so far ( certainly able to hold 28v and pop the 25A fuses if forced !)
