A higher gear ratio will diminish the rate of acceleration on flat ground. Regarding changing sprockets: A sprocket change that increases the gear ratio will lower the torque at the rear wheel which will lower rate of acceleration and hill climbing ability. Different scooters, riders, and riding conditions will affect the range of different size battery packs so there is no definite black and white answer to this question. That probably depends a lot on the gearing, how fast the scooter is driven, the terrain it is driven on, etc. I am not sure if adding an additional battery will result in a decrease in range or not though. Regarding increased Voltage: Adding an additional battery usually does not result in increased range because the power consumption of the motor will increase along with the increase in Voltage. For motors in the 900-1000 Watt range, a top speed gearing of 25 MPH or less is suitable. Increasing the Voltage will also work, however, could possibly overheat and burn out the motor. Regarding ways to add speed: Changing the sprockets for a top speed that is within reason for the power of the motor will work. Thank you for joining our forum and for your very well formatted list of questions.

Sorry for the long winded first post but I wanted to confirm my understandings before I get into specific questions. This seems to be where Lipo/Lion batteries enter the conversation and blow out the budget. Increased Range & Speed: This is always the question it seems but it appears that to truly increase range and speed you must increase the voltage of your scooter AND add batteries that are of considerably higher amp:hour size. So if it comes stock with three 7ah batteries, going to three 10ah batteries would increase range by 43% (more or less). Range: It would appear that the simplest way to add range is to replace the existing size batteries for those of a larger capacity. Is that correct? Would acceleration (even on flats) be also diminished? Changing Sprockets: It is my understanding that changing my motor or wheel (or both) sprocket can increase overall top end speed but it would be at the expense of hill-climb ability and torque. Increased Voltage: By increasing voltage by adding an additional battery, I do NOT necessarily gain more range because even though I add another battery the draw of power will be higher and I will still be at the range of the aH of the battery, correct? I have read that, for example, increasing a 24v scooter to 36v will reduce my range by 33%. Either by altering the sprockets or by increasing the voltage, correct? Are there any other simple methods? Ways to Add Speed: There are two common ways to increase speed. Answers to these questions would be most appreciated. I've done a fair bit of research and I think I've got my bearings but I still would like to confirm on some of my understandings. They are fun but (as you can probably guess) we wouldn't mind more speed and range out of them. I just acquired two new (to us) electric scooters the eZip 1000 and the eZip 900.
