A few people have been scammed on the site, Only use paypal to pay for items for sale by other members. If they will not use paypal, its likely a scam NEVER SEND E-TRANSFERS OF ANY KIND.
The bike rides fine but appears to be stuck in sport mode and the display is showing both D and S at the same time - toggling the lever doesn't appear to do anything , though works fine switching between neutral.
Any ideas?
