eMoto Ridge 2.0 Upgrade Questions

[wsoxfan2005]

Hello,

I have an eMoto Ridge 2.0 ebike which I absolutely love. (No longer in production)

The bike has a 250W (350W peak) motor and a 37V 9ah battery.

I live near Tacoma, WA. and needless to say that the area is quite hilly. For the most part I find that 250W is enough and since I have a two speed control there are times that I ride in low. With that said, there are hills around here that I have a very hard time climbing. I really wish I had a little extra oomph to climb those hills.

I really can’t afford a new bike and on top of that I really like the bike I have so I am thinking of doing an upgrade to a 500W motor.

I found a rear wheel drive that is sold in the UK that can switch from 250W to 500W that comes with a 5 speed controller for a 36V battery pack. This set up would allow me to run the motor @ 250W most of the time and 500W when I need that little extra boost in power. I also really like the idea of a 5 speed controller and I found that I can buy the 5 speed controller by itself that is for a 36V battery.

It seems to me that I can accomplish the same thing with a 500W 5 speed controller. If I have a 500W motor and I run it at speed #2 I should be running @ 200W. Here is my first question, am I thinking correctly on this?

The other thing is that since I already have a fully built ebike with a throttle, speed sensor, brakes, and battery pack the only thing that I should need is a new rear wheel and controller that is as long as I get a 36V rear wheel and speed controller. This is my second question, am I right here?

My other concern is my bike is fairly quiet and I am looking for a motor that is quiet also.

Again, I am not looking to break the speed of sound. I pedal in assist mode 99.99% of the time. I am more concerned about battery life and distance then speed. If I can conquer some of these hills around here that would be awesome.

Anyways, I am a newbie at this and I appreciate any input that you can offer.

Thank you in advance.

Pete

Would that the World was so simple.
The motor has a rating, usually half of what it can handle continous.
A 500 Watt motor will add nothing to your existing system, and "speed switches" add even less.
They are limiters, they take what the controller will do, and reduce it in stages.
You need to study up on basic electrical principles, but here it is in it's most basic;
Volts-speed
Amps acelleration
If you don't care about faster and your battery is good, you can keep your battery(and Doctor).
A)If you want a small boost in climbing, you could replace your controller with a 20A to 22 A controller and keep the same motor.
B)If you want a bigger boost, then you need about a 30 Amp controller and a motor that will take the increase.
For A, you probably could keep your wires and stuff and just replace a few connectors.
For B, you might be better off stripping everything electrical, and rewiring.
For more boost*and faster (they go together now), you need need higher Volts and a motor that matches, speed wise.
Other than another controller, there really aren't any free and easy mod;'s.

I don't know for sure but this might be a cheap (free but small) upgrade possibility:
