This is second one of these I bought so I can have 2 bikes but share a battery. Great motor, but didn't like the default settings at all. The lowest PAS settings where too powerful and the throttle was full power up to 25mph on any setting. Anyhow I used the USB programming cable I used on the previous and the Penoff programming code to reset things. Basically set each PAS level X to Xx10% current and throttle according to PAS level (eg level 1 is 10% max current, PAS 2 is 20% max current etc). And reset top speed to 16mph. This is perfect for my usage. Installed on Dahon folder so ideal to take on train, bus etc. Good and prompt delivery service from Eclipsebikes. Review submitted 09/26/2018.
