Looking for advice on GEM E2
How much difference in performance will be made if a certain amount of weight is added to the e2.
Has anyone noticed what power is lost or mileage range s reduced?
If 500 lb is added?
Another question has anyone added additional batteries to an e2 or made adjustments to the engine?
Any feedback would be appreciated.

hi baron… the e2 is rated to carry 750# so you should not see any range or power loss at 500#… not sure about your question is this a load plus passenger weight… there are ways to get more power but you will lose range… with the 12v system there is a trade off… look at the Ride 4 Fun site for a larger motor…
