Speeds can be locked at 20mph or up to 28mph depending on region. PAS with 9 levels. But the best part is it comes off in 5 seconds (really) leaving nothing on the bike at all, no battery, no motor, no controllers. So no theft worries. And - unlike a hub system - when you pause the PAS the motor fully retracts from the wheel so there is no cogging or drag. I absolutely love mine. Happy to answer questions if you have them; totally understand if it's not right for you, too. Oh - and you can move it to any other bike if you get a new one in the future, too.
