∙ 13y agoHard to tell, there are too many unknowns. There are sites that deal with bicyclists output power vs speed, you could try track one of those down and see what 250 W would give you, and treat that as a max.

∙ 13y agoBattery dying - there isn't enough power left in the battery to turn the motor over during the starting process. Could also be the starter selenoid or the starter motor itself.
I would suggest that you connect all components in series. That is, + of the first battery to - of the second. + of that battery to the switch and the second terminal of the switch to the motor. The last wire from the motor back to the - of the first battery. To reverse direction of the motor just swap the leads. There are many factors that will also affect speed such as how the motor is connected to the wheels, type of bearings, even the width and diameter of the wheels. Good luck and have fun!
That depends on the relative sizes of the gear shafts used to transmit power from the motor to the wheel. For instance, if they were the same size, and no gears in between, then the wheel would rotate 400 times a minute (RPM), which is 6.66 times a second. But usually gears transmit power in such a way that the wheel rotates slower than the motor (less RPM) but with more power.
It depends on your speed controller, motor, and battery. I have a brushless setup on my E10 with a Li-Po battery and several other mods. It goes over 60mph.
A brushed motor is an electric motor, and as such it needs a battery. Bigger batteries generally go faster. In addition to the size of the battery, the size of the engine also controls the top speed, again following the rule of bigger is generally better. However, brushed motors are higher mantinance than their brushless cousins.
Sounds like something is shorting out whenever the ignition key is turned on. Could be the starter motor, as that is the first electrical connection after the battery.
In any electric toothbrush there is an electric motor and a battery inside the handle. When you use the on/off switch to connect the motor to the battery, the motor spins very fast and drives some gears which turn the brush head backwards and forwards to clean your teeth. Some electric toothbrushes have replaceable batteries which means that, when the battery runs down so that the motor won't run, you have to take out the old battery and put in a new one. If the toothbrush is the kind that is rechargeable, it has a battery which does not have to be removed and replaced by a new one. Instead, you place the handle onto a charger unit and when that is plugged into a home ac power socket it re-charges the battery.
fast...very fast.
Google "fast wheel" and you'll get some very different answers. Take your pick!
Yeah.
Wheel bearings help your wheels to roll smooth and fast.
That varies with battery chemistry.
