Tuning for the Giant E+ range is now available!
The tuning is performed by connecting a laptop to your Giant E+ Syncdrive ebike. Once connected we are able to set a custom speed limit up to 70kph without any need for hardware modifications.
This is achieved by modifying the value of the wheel circumference in the giant firmware to a custom value depending on the required speed. If you have a speedometer on your ebike the reading will be incorrect by the ratio of the original circumference to the new value. For example when changing the limit to 50kph the circumference is halved which means when the speedometer reads 20kph you will be traveling 40kph.
The change is completely reversible should you have any need to return to the stock settings. Such as warranty claims or sale of the bike.
What ramifications does this have on battery performance?
Hi Darren
It depends how you ride the bike. If you normally ride within the 25km/h limit then the whole ride your bike is assisting you. Once unlocked the bike will still assist you the whole ride so battery life is similar. If you previously rode often above the cut out speed then once unlocked you will use slightly more battery as your bike is now always assisting you rather then being off for some of the time.
Is there a cost to change the software back to factory settings for a warranty claim? Is there then another cost to go back to the modified version?
Hi Steven
No cost to change back to factory settings and no cost to restore unlock after a claim. Some Agents may charge a small fee to cover there travel time if they have to travel a long distance to perform the modification.
Hi – Contacted the Newcastle dealer but was told they cannot do Giant as they don’t have the required plug?

Yes the Giant Service tool is very hard to obtain so not all dealers currently can perform the upgrade, Our Sydney agent is the closest agent to Newcastle that has access to the Giant Service tool and is able to perform the upgrade.

I’m in N California and I want someone to do this for me. do you have anyone here to contact? I have a new 2020 Reign E 2 pro.
WIll this draw more energy from the battery, I usually ride in eco or #2 power modes.
Hi Robert
We do not have anyone that can perform the upgrade for you, If you can get hold of a Giant service tool usb dongle we can help you perform the upgrade on your own bike. Typically giant will not sell the service tool to end users, You may be able to loan one if you have a good relationship with a local giant store.

Hi Can you advise the additional impact on the battery ? On my Giant E-Fathom I use 70% of the battery for a 40k ride with maxed power.
Whats the likely impact to this 70% with your update to the bios?
Cheers
Hi Nic
We have not noticed any measurable change in battery life after the upgrade. If you rode above 25km/ph without assistance for a large portion of the ride then with the bike unlocked and assistance being offered the whole ride you may be able to notice a difference.
Do you have anyone in Perth that can do the reflash?
The unit has a memory that gives average speed of the bike etc and is used in warranty claims. After reflashing to stock do these values remain?
Yes Derek is our perth agent 0478111362. We have returned a number of bikes to standard after being flashed and have had no issues with warranty claims or detection of the bike being modified in any way.
