How did you program to suite the GS?krunchi said:I bought a gear sensor from emax ebikes to run on my bbs02. I find it works really good, some of the issues might be down to individual set up, i.e. programmed delay and how quick or well your drive train is tuned to shift.
Three samples and a 4th final version, $0.00.Ade said:Stuff is worth exactly what people are willing to pay for it.
tomjasz said:Given the other exagerations in their sales pitches, I need to see some proof of different firmware before I could make that announcement. Lectric is the distributor for GS and Lectric is known for wild markups. Like the Dolphin battery base for $75 plus shipping. A $15 cost from EM3ev. That said, Gearsensor direct was the same price. Hopefully someone will finally post the Lectric program screens and we can see what's up.
General description
This unique patent pending system developed and made in Czech Republic is based on intelligent GearSensor fixed on the shifting cable, which cuts off the motor drive when the rider activates gear shifting. This brand new technical solution eliminates user-unfriendly and noisy rear derailleur shifting which is caused by chain over straining. GearSensor in combination with the front derailleur allows smooth shifting even if the e-bike is equipped by double/triple chain wheel mid-motor. In addition GearSensor in combination with the internal gear hubs allows perfect shifting performance.
Programmable processors enable individual time setting for shifting gears up and down and adjust micro movement sensitivity of the inner cable to avoid the motor cutting out caused by cable vibration during riding the e-bike.
GearSensor models
The GearSensor is divided into these different models:
1) Model GS-D is a universal model for both derailleurs (front and rear). On this model restarting of the motor depends on the FINISH of the shifting cable movement. This is because system has to wait until the movement of the chain is finished to choose a sprocket or a chainring. MODEL GS-D IS MARKED ON THE CABLE WITH A WHITE STICKER (samples marking).
2) Model GS-I is the model for INTERNAL GEAR HUBS. On this model restarting of the motor depends on the START of the shifting cable movement, plus defined time period. This is because system does not need to wait until the end of the movement of the chain to choose a sprocket or a chainring. MODEL GS-I IS MARKED ON THE CABLE WITH A RED STICKER (samples marking).
Bafang BBS01 and BBS02 systems:
Every Bafang BBS motor is equipped with two connectors for brake sensors (HIGO, yellow 3-pin). GearSensors which are compatible with BBS motors are also supplied with the same HIGO connectors. First option is to connect the GearSensor directly to one of these connectors for brakes. Please note that if you do connect GearSensor into this connector, then the restart of the motor could possibly be longer than it should be, because this connector was programmed for brake sensors. The other option is to order directly from Bafang BBS motors with a connector especially programmed for GearSensor, so the restart of the motor will be very fast. For further details please contact us by e-mail and we will help you with the specification of this order.
brickwall said:Thank you for all that information. I know that using the gear sensor with a brake sensor port is not ideal because of the delay, but I believe most people that are experiencing that are using a derailleur system. Anyone has any experience with a gear sensor on an IGH system? Because apparently, the two versions are programmed very differently.
If there are adjustments, would you please share them?eMax said:There is however a few parameters in the programming of the controller (for Bafangs) that can be tweaked to improve the performance of the gearsensor.
I can't imagine they would produce two when one would work on both systems. So far no reports on using the derailleur version on an IGH.brickwall said:I've read about there being a difference in the sensor, even though the basic principle is the same. However, the actual usage between the two models is very different. With a derailleur system you need to pedal when shifting, while with an internally geared system you absolutely shouldn't. That's why I'm asking, because maybe one or the other is better in actual use.

Releasing the throttle doesn't stop the motor.dvdrwsor said:I'm thinking of adding a gear sensor on a IGH with a belt drive. Correct me if I'm wrong, but isn't gear sensor the same thing as in:
-release the throttle
-change gear
-engage the throttle
?
tomjasz said:-release the throttle
-tap brake lever(or back pedal)
-change gear
-engage the throttle
That's nearly the same
