Frequently asked questions about the L20 3.0 Pro
Does it work with the L20 3.0 Pro updated to the latest firmware?
Yes. The app talks to the bike's controller via Bluetooth and operation has been verified in the field with updated firmware too. If anything doesn't work, write to us: the L20 is the bike the app is developed on.
How fast does the unlocked L20 3.0 Pro go?
With NO LIMIT the motor no longer stops assisting at 25 km/h. The actual speed depends on motor, battery, weight, route and gear: the app removes the software limit, it doesn't increase power or alter the motor's factory parameters.
What exactly has been tested on the L20 3.0 Pro?
Everything: connection, unlock, custom limits, return to 25 km/h, speedometer, parameter reading, ON/OFF widget, lights and pedal-assist modes. It's the app's reference model, used km after km during development.
Can I try the app on my L20 3.0 Pro before paying?
Yes. The free version connects to the bike and shows the speedometer and parameters: that way you check that your L20 3.0 Pro is recognised before buying the license. The unlock only activates with the Full license; returning to 25 km/h is always available.
How do I get back to a legal bike?
With one tap: press the 25 km/h button in the app or the 25 / NO LIMIT widget on your phone's home screen, then switch the bike off and on. The factory limit is restored and the bike is compliant again with EU pedelec rules (25 km/h). Returning to 25 km/h is always available, even without a license.
How much does the license cost?
€29.99 one-time only, paid via PayPal directly in the app. The license is lifetime, no renewals, and activates automatically right after payment.
Is it legal to ride the unlocked bike?
Unlocking turns the e-bike into a vehicle that no longer complies with EU Regulation 168/2013 (EPAC/pedelec class): riding it on public roads and areas is prohibited. Use is allowed exclusively on private land closed to traffic, as you declare you know by accepting the in-app disclaimer.
Does unlocking void the warranty?
Unlocking stresses the motor, battery and components beyond their design limits and may void the manufacturer's warranty, besides causing accelerated wear. Think it through before activating NO LIMIT.
⚠︎ Legal warning
Unlocking the speed alters the vehicle's factory characteristics and voids its compliance with EU Regulation 168/2013 and local road law (in Italy: art. 50 of the Highway Code): the vehicle becomes a non-type-approved moped, not allowed on roads, cycle paths or public areas.
The app is intended for use of the vehicle exclusively on private land closed to traffic. The user declares they are aware of this and indemnifies the developers from any civil and criminal liability, expressly accepting these clauses at the app's first launch.
