New to this forum and have new XP trike < 100 miles for the wife. Found great info here about the settings that has been very helpful! We love the oblong handle grips, but find the round throttle shape makes it harder to use for very long, especially when wearing gloves. I found several throttle conversion threads here, but a search yields so many results I don't know if this hack has been motioned before or not. I am testing by placing a strip of foam on both the top and bottom of the throttle grip and wrapped it with tape to create an oblong shaped throttle grip. The goal it for it to fit the hand in the engaged position. Prototype-A has been a huge improvement and I am contemplating modifying the shape/placement/material of the lower strip to see if it could be thumb engaged, but not yet convinced enough to try. Hope this helps someone else and engages other engineers to add their improvement ideas. ...And if Lectric monitors this forum, I would suggest they test this out for future manufacturing.
