Updating the firmware on your MAHLE X35 system is quick and easy, but it must be done in person.
Where to update
Any MAHLE dealer with a GCU-USB cable can perform the update
Or, visit any Ribble showroom, where we’ll update your firmware free of charge
No booking is needed — just bring your bike in at a time that suits you
The process takes around 5 minutes and can usually be done while you wait
Important notes
The update cannot be carried out if your bike has an active system error (flashing pink/purple light on the iWoc). The error must be cleared first
Make sure your eBike battery is charged above 50% before attempting the update
