The Bafang motor if I'm not mistaken was originally designed as a commuter bike upgrade (it's got old school road bike square-taper BB axles and a 48T steel chainring). So now what? Well from what I found, this only proves to be advantageous when commuting on the flats. Maybe I could go faster if I want to look stupid and spin like crazy with it. It has 2.75" wheels and the fastest it can travel is roundabouts 45kph. Just so happens it has a 42T chainring driving the smallest cog on MOST cassettes - which is an 11T cog. Think about this for a sec - the highest gear ratio on my Bafang eMTB is 1:3.8 ratio. I've got time, I'll make myself a cup of coffee and write my thoughts about this. This motor system is fully unrestricted and will assist regardless of what speed or cadence you're on - BUT we often forget that the top speed will always be limited by your highest gearing ratio. Well, I have another eMTB (other than my Trance E+) and that started life as an analogue trail bike which was retrofitted with a Bafang motor. For those who have not experienced a fully unrestricted eBike, this business of de-restricting a motor is irresistible - the grass is greener on the other side, right?
