I believe you can get Wisper to remove the speed restriction but you will need to sign a disclaimer forfeiting any warranty you may have. If there was a sequence to get into the service menu settings it would be difficult to guess it....

Thanks for that. Unfortunately, I do not have that option on my controller. The guy who found he could access that screen, just got lucky it seems..

Hi all I am new here. Was googling about de restricting ebikes and ended up here. I have a Wisper 905 Torque which currently has a top speed restriction of 15 mph. How would I go about removing this? I am in the UK, and would use the higher speed off road. Many thanks for any advise. Harry
