That's right wheel size it is a good looking bike but was told I could bypass speed limiter ???

Motors spin at a maximum speed, which depends on the battery voltage. No controller setting or anything else can change that. Your motor is 195 rpm at 36v. If you do the calculation to convert the circumference of a 26" wheel at 195 rpm, you'll see that it comes to a bit below 15 mph; however, your battery is working at about 41v when fully charged, so you get an extra 1 mph.

You can test if you're motor limited or controller limited by charging up the battery, lift the wheel off the ground and spin up the motor to maximum speed (use first gear). Make a note of what it is. then go out for a long ride to flatten the battery to somewhere below half-way down, then do the test again. If the speeds are identical, you're limited by the controller. If the second result is a lower speed, you're limited by the motor.

That's very helpful thanks will try that in the morning and come back

Chris you need to understand what is being said here.
You don't have a fast wound motor, it is a slow speed 195rpm designed for low down torque ideal for hill climbing so speed will not be fast on level ground.
Chances are that 195rpm is the no load speed so the actual load speed would be about 163rpm, the only way to get more speed is to run it at 48v.

Not necessarily so. Additional voltage will create additional torque and depending on the motor design could result in additional rotational speed. In a traditional DC motor that would be case. If the motor is being driven by an electronically switched three phase generator ,The speed of rotation will be set by an internal clock inside that controller, and this will be part of the microprocessor s firmware.
