HTD3M Pulley 20 Teeth 8mm Bore Motor Belt Pulleys Timing Pulleys DIY fit for Width 15mm Timing Belt for CNC Laser Machine Engraving Machine Pack of 1pcs

These motor pulley are so durable and feel like they are top quality motor pulleys. 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.

all good
