The FAQ for my E-Bike kit says:

" 48V 1,000W eBay kits? I often get questions from customers asking if we carry a 1,000W kit. The simple answer is there is no such thing. It is just a selling tactic. A true 1,000W wheel/motor weighs on the order of 50 lbs. What they are doing is simply overvolting a 500W motor. so that it is pulling the same amount of amps as a 1,000W motor. Our motors can run up to 750W without generating any heat due to over amperage. Keep in mind if you over volt our kits you will be voiding your warranty as our product liability only allows the federal law speed, not to mention that overvolting for higher speeds is incredibly dangerous."

and also:

"Also these kits are capable of running at higher voltages with no modification. Although we will not warranty anything over 36V. At 36V it runs at the correct and safe speed that it was meant for. If you are running at 72V and fry your controller please do not try and return to me as we will know immediately upon opening the speed controller what happened to it."

This tell me I can run up to 750 watts and that the motor is limited now.. it must be below that. ( I don't have a meter to check it yet.. getting one soon) If it can do 750 safely, I want it to.


So.. what happens when my warranty runs out in 6 mo? If this motor can be safely overvolted to make me go say 26 MPH, How do I do that?

Must I buy a new speed controller? Can I adjust this one for higher output? I shouldn't have to according to the info above it seems but I'm new to this and want the Pro's and Con's. Specs on the controller say, 36-60V 22A-35A max.

I want to get a Lifepo4 style battery or the one Amepedbikes sells ( using SLA now) BUT If I am going to spend 3 to 500 dollars on a battery.. I might as well get a speed controller ( if needed) that will make my motor go faster and invest in the 48 V battery - better for the money.

I don't want to go too fast.. just a few more MPH than i'm getting now. I feel the cops won't notice a few extra MPH if that's all I am getting. If this is all true it looks like my 500 dollar kit is turning out to be a better deal than I thought.
