VOLspeed E-Bike Tuning Kit for Giant Syncdrive Sport / Pro / Life / Core V5

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed, ensuring smooth motor control free from interruptions by speed limits. The achievable speed largely depends on the eBike model and can be calculated using the following formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1,000,000 [mm/km]

VOLspeed can be activated directly on your bike’s controllers by pressing the [- + - +] sequence. Upon activation, the speed limit is displayed for 5 seconds. Default value: 20 mph (32 km/h). If you would like to change the maximum speed, use the [+/-] keys. The set value is saved until you change it.

To deactivate the tuning kit, press the [- + - +] sequence again.

The tuning is automatically switched off each time the bike is turned on.

VOLspeed V5 features a "softer curtailment behavior" (dynamic mode), which significantly softens the otherwise abrupt deceleration at the speed limit. It ensures correct display of speed, distance covered, and average speed at all times, as well as accurate total mileage of the bike even after the tuning module has been removed. The wheel circumference is adjustable (+/-10%) to improve the accuracy of the speed display and distance measurement.
