Will 250W motor take 20A?

[mifletz]

This 48V 250W bike comes with a 11A battery

If you change the controller and put in this 20A battery (48V)






will the 250W motor take it?

Since the batteries are the same voltage there shouldn't be a problem, going from a 11AH to a 20AH battery only increases the time it takes to discharge the battery. The larger amp hour battery only increases the reserve capacity.

What is the easiest way of overriding the 250W EU restriction on these types of bikes, to get more power to the rear wheel for better hill-ascending purposes?

You may want to p.m. bikenut here on the forum, he has a lot of time on electric bikes.

I have been running a 24v 250w geared hub with a 48v 24w controller on 12s lipos for several years. Dont think you need to worry.
Most controllers have a limiter wire that can simply be disconnected, unless they have dropped or internalized that feature in the EU.

I forgot about you cannon ball, you can help him better than me. Most of my experience is on industrial motive equipment like electric forklifts, tugs and golf carts.

II have ridden it many times pulling the max amps the controller will give which as I remember is 24a(label is too faded to read) so its pulling 1000+w. Doesn't seem to bother it. My main concern is the gears in the hub, l assume they are plastic so I apply the power gradually. I like to run it full out on a fresh charge(50v). It pretty quick then.Been riding this bike as a errand runner for several years with out issues. Its my favorite Ebike.
