I use these for my E-boards. I went from a 3to1 ratio with a 48t wheel pulley& 16t motor pulley topping at 22mph. To a 2.5 to 1 ratio and tops out at 28mph with me on. I weight 194lbs. The change in ratio extended my battery range it feels as well. Of course I lost a little bit of torque but I plan on buying another pair of 18t and 15t or 16t of this maker to change out my gear ratio when I feel like switching to higher torque for mountain climbing. It feels so easy to switch gears with these brand motor pulley that I don’t feel like I’ll strip or wear out the bolts switching out pulleys. I do use removable thread lock just for extra precautions lol.
