I had this type. I needn't have worried, it was killed by rain anyway. Always splashing about me - this throttle had to be pushed down a long way, so I had it angled up about 40 degrees... which might have hastened it's demise? Whatever, the new push-forward throttle looks better waterproofed, but I don't need it until I need to quickly install it, tool-lessly, if one or both my legs fall off, so I can throttle The GuerneyMobile™®©℠ back to the The Guerney Cave™®©℠.
Well That looks same as 2nd one i have ordered, also I had same thumb throttle on a electric moped ERider I had and sold and I quite liked that type of throttle, so hope it will work on bike
