Help with Pedec Install

[HombreNeuvoElectro]

Hi all,

I hope someone can help me out as i cannot get a new pedelec sensor i have bought to run the motor.

The pedel sensor that came off the bike is below



It has a red/blue/black input from the controller. Measuring across the controller the input from the controller to pedel sensor is just in 13V

I removed the old one and first installed the new one on the drive side. The new sensor has red/green/black wire and i had to solder some joins since the connector on the sensor was male and connector on the controller also male.

I first tried to feed the existing 13v into it a it will not run the motor.

Then i put a wire direct from the other side of the controller to feed the sensor just under 5v and still nothing



When i short the red against the green above the motor runs

I cannot get the pedel sensor to supply the required voltage back to the controller to run the motor

Here is the pedel sensor now on the non drive side.




I hope someone could help me out in making some progress.

Thanks in advance

Hi, that sensor looks exactly like the one on my Ezee Forza.

I do not know if it's possible to easily bypass/fool this sensor however, but you may get lucky if you find a thread about bypassing an Ezee sensor.

It may be worth trying to flip the plastic disc with the holes in around, as mine does not work in reverse.

Good luck.

The first photo shows an optical sensor. The picture of the controller looks like the one that is compatible with it (from its shape). As far as I know the onboard electronics of the optical sensor give a continuous on signal to the controller. The last photos show a magnetic sensor, which gives pulses that the controller interprets. The two types of sensor are not compatible, so you need different controllers.

I've got one of those optical sensors somewhere if you get stuck, but it would probably be a good idea to get a new controller like the KU63 from BMSbattery (about £20 inc shipping) because the magnetic sensors are a bit more reliable and easier to install.

Hi d8veh,

Thanks for the help on that. I completely removed the pedelec sensor and just wired the motor to run continuously so i can sit on it like a moped.The enclosure for the controller is very small and i do not think it would accept a different controller. I will leave the bike as is for the moment and it is great fund wired direct and using the lever to cut the power but it eats the battery and i am not sure how low it will remain reliable.

Anyways i have a new project on the horizon and i am sure you will approve of my choice of bike.

I miss the photos on your threads over a pedelecs as you had some very good threads on modifying the cheap wattmeters and other things

I still have that optical sensor if you want it. Better to use a 10k potentiometr than an on/off switch because you can set the speed to whatever yoy want. You can get a 1" potting box, a 10k pot and a 2 position toggle switch from Maplin for about a fiver. Mount the pot in the box and the switch on the side and then zip-tie it to the handlebars. The wiring is simple: The red throttle wire to one side of the pot and the black to the other, then the signal wire through the switch to the middle pot pin and away you go. I find this arrangement better than a throttle for low powered bikes.

I find this forum better than Pedelecs. There's less politics, bias and hidden agendas; and too many opinions not based on knowledge.
