For bikes with drop handlebars, this is used instead of the BionX Standard Magnetic Brake Switch included with BionX Electric Bike Kits.
Can be used in line with the brake cable at the top tube cable stop using the donut magnet provided with the BionX kit.
When the sensor is installed at the cable stop, the brake switch has an inverse relationship with the magnet; the brake/regeneration is engaged when the magnet is pulled near the sensor, rather than when it is pulled away from the sensor.
(On upright bars, the sensor and magnet are installed at the brake lever.)
The sensors come in four cable lengths:
5.5 in (140mm), 15 in (380mm), 18.1 in (460mm), and 22 in (560mm).
Choose the length that best matches the length of your brake housing from your brake levers to the cable stop.
