VOLspeed V4 - Giant Syncdrive Sport / Pro / Life / Core

The VOLspeed V4 is a smart tuning kit offering the unique capability to set both the speed limit and the downshift behavior, as well as the wheel circumference, via the display. With VOLspeed, you can view real data such as maximum and average speeds, daily mileage, and cruising range.

Unlike other tuning modules that nearly eliminate the speed limit, this module allows for a very sporty riding style with moderate battery consumption by slightly increasing the limit, e.g., to 32 km/h. If desired, you can adjust the limit using the "Plus" and "Minus" keys, with possible values ranging from 25 to 45 km/h (15.5 to 28 mph), the default being 32 km/h (20 mph). The set value is retained until you decide to change it.

For a more natural riding experience, the dynamic mode expands the downshift across a broader speed range, significantly reducing the so-called "wall effect."

The display is not necessary to enjoy the new speed limit with VOLspeed. However, to utilize all tuning functions, including the display of total kilometers and speed, a display is required. If your e-bike lacks a display, you may consider retrofitting with the Ride Dash Plus, for example.

NOTE: Do not use the Ride Control app as a display, as it may prompt you to update the software, which should be avoided.

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 V4 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.

This tuning kit is compatible with:
Giant SyncDrive Sport / Pro / Life / Core drive systems from model year 2017 with displays EVO, EVO-SG, CHARGE, and PLUS, along with control units ONE, DASH 2 IN 1-SG, ERGO-SG, and ERGO2-SG.




Not compatible with:
Smart Gateway software version 20240314000 or newer. Avoid any software updates to the drive system as they could impair the function of the tuning and/or the bike.

For more about incompatible software versions, find information here: https://blog.volspeed.de/giant-smart-gateway-compatibility-705/?lang=en

The tuning module is only compatible with e-bikes that have an electric motor support of up to 16 mph (25 km/h) ex works. It does not support children’s e-bikes with support up to 20 km/h (12 mph) and Speed-e-bikes with support up to 45 km/h (28 mph).

For all original Yamaha motors (PW, PW-X, PW-X2, PW-X3, PW-SE, PW-TE, PW-ST), you would need the VOLspeed V3 - Yamaha PW-X / PW-X2 / PW-SE / PW-ST / PW-TE / PW-CE

Giant SyncDrive motors before model year 2017 and SyncDrive Pro2 from model year 2022 onwards require the VOLspeed Giant Syncdrive Pro2 / Sport2 V4

When connecting Tuning Kit to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our tuning kit is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us. If you are planning to install Volspeed on a brand-new bike, make sure you ride it for at least 0.6 miles (1 km) before the tuning kit is activated.
