How to Set Your Speed Limit on VOLspeed Kits

VOLspeed kits allow you to set a custom maximum speed limit between 25 km/h and 45 km/h (approximately 15.5 mph to 28 mph). Here's how to adjust it.

Before You Start

Make sure:

  • Your chip is installed correctly

  • Your bike is turned ON

  • For Smart System bikes: Your phone is connected via Bluetooth to the eBike Flow app

Setting Speed Limit on VOLspeed V2 (Bosch Smart System)

Step 1: Open the Flow App

Open the Bosch eBike Flow app on your phone and ensure it's connected to your bike.

Step 2: Go to the Ride Screen

Tap the Ride screen icon (the middle icon at the bottom of the app). This is important - the buttons won't work from other screens.

Step 3: Activate the Chip

Press the buttons on your bike's display in this sequence: - + - + (minus, plus, minus, plus)

You should see 32 km/h appear on the display, indicating the chip is now active.

Step 4: Adjust the Speed (Act Quickly!)

Immediately after activation, before the display resets:

  • Press + to increase the speed limit

  • Press - to decrease the speed limit

Each press changes the limit by 1 km/h. The maximum is 45 km/h (28 mph).

Step 5: Confirm the Setting

The speed setting is automatically saved. Next time you activate the chip, it will remember your chosen limit.

Important: The chip deactivates when you turn off the bike. You'll need to re-activate it each ride using the - + - + sequence, but your speed setting will be remembered.

Setting Speed Limit on VOLspeed V4 (Bosch Gen 3/4)

Step 1: Turn On Your Bike

Make sure your bike is powered on and the display is active.

Step 2: Activate the Chip

Press and hold the WALK button for approximately 3 seconds until you see the activation confirmation.

Step 3: Adjust the Speed

While the speed indicator is showing:

  • Use the + and - buttons to adjust your desired maximum speed

  • The setting is saved automatically

Common Questions

Q: Why does my chip turn off when I stop the bike?

A: This is normal. The chip deactivates when the bike is turned off for safety reasons. Simply re-activate it when you start your next ride.

Q: Can I set it higher than 45 km/h?

A: No, 45 km/h (28 mph) is the maximum limit built into VOLspeed kits.

Q: Why can't I change the speed when I press + or -?

A: You need to act quickly after activation. The adjustment window is only open for a few seconds after you see the speed display. If you miss it, turn the bike off and on, then try the activation sequence again.

Q: It changes my assist mode instead of the speed - what am I doing wrong?

A: Make sure you're on the Ride screen in the Flow app, not the main screen. The buttons behave differently depending on which screen is active.

Q: Is my speed setting saved?

A: Yes! Once you set your preferred speed, it's saved in the chip. You only need to re-activate the chip each ride, not re-set the speed.

Troubleshooting

If the chip won't activate:

  • Check all connections are secure

  • Make sure your phone is connected via Bluetooth (Smart System only)

  • Try turning the bike off and on again

If buttons aren't responding:

  • Press the button sequence more quickly

  • Ensure you're on the correct screen in the app

  • Check your display is responding to other inputs
