MX650 Speed Upgrade

Hello, I was wondering if I got a 13 tooth motor sprocket and a 65 tooth wheel sprocket can I get up to 26 MPH? I just want to be able to reach that speed without spending anything over $200. But also what #25 chain would I need for the sprocket change? Or if a 13 tooth and 65 tooth sprocket won’t work, what can get me up to 26 MPH?

According to our motor power calculator, the fastest a 650 Watt brushed motor could propel a scooter or bike on flat ground is around 22 MPH. This is mostly due to the amount of air resistance (drag) that the bike will encounter at that speed. 



Due to this calculation we do not recommend gearing the bike over 22 MPH otherwise the motor will lug and produce less horsepower than it is capable of which will reduce the top speed even more.
