Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Finally bit the bullet and bought a BBSHD motor and 48V 20AH battery to go with it. It's probably common knowledge that it's an easy fit to most bikes and it was 3 hours later and it's on the road. Details: Most if not all new stock sold is "52 Volts" Programming the operating parameters is easy with a special cable or make your own The 52V unit shows incorrect battery capacity when using a 48V battery - and there is no simple way to tell it to think it's a 48V battery via the display unit. Fixes: Downgrading firmware to something a bit older fixes the wrong battery capacity issue. Also, this previous f/w fixes a very annoying thing which is the reduction to 1/2 power when the battery capacity drops below something or other. In my case it was when it went below 50V. This is not good at all with the 48V pack. I was looking at 1/2 power for about 1/2 of the 20 Ah battery's capacity. Boring. The old f/w lets you use full power all the way down to about 41V LV cut-off or whatever you choose it to be. This is much better. Summary: very good motor, strong, quiet, clean, well suited for the nominal 1000W output. Easy to fit to a bike. A lot of fun. It gets me and my fat arse up any hill and I live in the Dandenongs which has many hills 10 or 20% gradients. No overheating problems A robust motor for the hills. Programming new firmware is easy to do. Firmware Update Controller 1-5.zip has all you need. It worked fine with my Win10 laptop but I needed to program it at 19,200 baud. Anyone here also got a Bafang motor on their bike? wronger than a phone book full of wrong phone numbers |
