Anyone know any hacks for this 48v 1000w kit I got on amazon

[mattyb1631]

I’d like to thank everyone for your help! Ied me in the right direction, I needed a new battery....... I bought a new battery 48v 20ah the bike works like a dream the battery came with its own charger. I charged It fully when I first got it and I’ve charged it up maybe 10 times since after each ride.... going around 30 mph Have 1000 W motor on the back Wheel from Amazon Came with 1000w controller also....Runs great but I need it to be faster LOL! researched and this controller doesn’t have a white wire loop to disconnect that limits the speed like some stock E bikes have on their controllers.....Is there something you can do internally or is there a wire that I am missing that can be disconnected like that white loop you see in the videos on YouTube? There’s no loops at all on this controller actually seems like there’s less wires then some of these stock controllers There’s no loops at all on this controller actually seems like there’s less wires then some of these stock controllers. controller is LY-48v1000w P-19EBE000002 can Anybody help?

You're probably at the limit for the voltage of the battery you have, and the power of the controller.

Most likely you'd need a higher voltage battery, and a higher-current controller (that can handle the higher voltage as well) (and the batteyr would have to be able to handle the higher current draw, too).

The battery would also need to be higher capacity (total wh), if you want the same range (or greater), because it will take more power to go faster.


To see the whole-system interdependencies of going faster, go to http://ebikes.ca/simulator and read the entire page so you know what everythign is and how to use it. Then pick different systems and see what they do, then increase their voltage and controller current, to see what they do. It doesn't matter if they are the same as what you have--the idea is just to see what kind of changes you need to make to a system to get speeds as much faster as you are after.



You're also probably going to want to upgrade the tires, wheels, and brakes on the bike, and probably the suspension, so you can control the bike at the higher speeds.

Hack you ask....

Controller shunt mod, adding more solder to the shunt wires in an even manner
A new, bigger controller (voltage and amps)
Adding Ferrofluid/Statorade to the motor. From www.ebikes.ca
Larger PTFE Teflon Phase wires for the motor
Sinewave controller if you want more silence
A new bigger, more efficient motor, like the Leafbike 1500W with a higher KV/Lower Turn Count for more speed

Shunt mod would get you to a faster 0-30 mph, but not a whole lot more top speed. And it would hurt your battery more too, which might not be worth it.

The traditional 'hack" for that size motor, is to put it on 72v, with a 40 amps controller. New controller, and new, different type battery that is able to handle 40 amps without problems. A bit costly, and your range will lower to 10 miles riding full speed. much more,, your motor melts. Its about the limit for that motor.

But by then, hey, you got your 72v battery, and a strong controller. Time to buy that much bigger motor.

Trips you down the more money road constantly, but its sure fun. If you want more speed cheaply, get a small, well used motorcycle or scooter, that does 60 mph easy. Really, to ride street fast, you want it all. Starts with tires, suspension, and then you should be wanting the body armor, the helmet, and the insurance.

Seriously,, I know this is a bit of a bummer, but enjoy what you got for the summer. Then plan all winter for the upgrades to make a safe -ish, but 40 mph e bike next season. Not starting with a motor, but starting with a very high quality full suspension bike, that will cost double what a used honda 125 would.

Actually, without replacing controller and battery, your only mean to a faster top speed is bigger tire. It would add some speed, at the cost of some acceleration and efficiency.

Always build a bike a little faster than your target top speed, with a battery capacity bigger than your expected range does require. Tricks to improve that afterward, are limited or costly.

I think you'd be happier and safer riding a small motorbike/motorcycle. You'd get some important features you don't have on your bike. Better tires, full suspension, better brakes, better weight distribution, etc, and the increased weight adds a lot to your stability. Even small pot holes on an eBike going 30+ MPH can cause huge problems. The extreme of this is the skinny tyred bikes the spandex crowd prefers.....zero margin of error on that sort of thing. When I went to a mountain type bike, wow, those big tyres w/ low pressure made riding much safer. My eBike w/ only front suspension gets a little squirrely going over 25 MPH, especially when cornering, unless the road is smooth.

What kit and battery did you buy? Possible links?
