    BBS02B - my look at driver settings

    I am currently using 0! Do not recall how I ended up here! I do know that setting some parameters to 0 can introduce strange behavior but I have not noticed any. I will take a look today and experiment with different values and report back....

    BBS02B - my look at driver settings

    Indeed! I have converted several bikes with the BBS02 for 'older' riders (like me) and found that initially there was some hesitation to use the bikes due to more performance orientation of the stock settings. Once they were changed to lower power profiles the riders were immediately more...

    BBS02B - my look at driver settings

    As an interested BBS02 user I am have some difficulty with your contention that the Limited Speed (%) in the basic tab refers to engine speed. If so it would seem that anything less than 50% would be of little value. In my experience it seems that the speed referred to is actually the road...

    Speed pulsing on BBS02

    Enjoyable is indeed the word I would use. As an 'older' rider who has lost the ability (or is it will) to take those long rides on a nice day, this thing makes all the difference in the world. I don't turn around now when I see a big hill and can just head out not worry about getting home. I...

    Speed pulsing on BBS02

    Thanks for the feedback. I have tried many combinations and it seems to have improved to the point where I don't think about it any more - maybe I'm just used to it now. I have the speed set at 26 and just ride adjusting power and gear selection as required to maintain the effort that I want to...

    Bbs02 48V on 29er - front chainring size?

    I guess it really depends on how fast you want to go and how hard you want to work. Assumimg all gears are useable it would seem that you have a speed range of about 15 to 48km/h at a cadence of 80 with the 48. I think a 44 is likely a better bet for all round use but it is not going to be a...

    BBSO2 low top speed

    It is always helpful to have a much data as possible to determine what is going on. What is the voltage and current are you seeing at 35km/h? Depending on a number of factors like loading and controller settings that could be the maximum achievable but I doubt it. Unless your load is 200kg and...

    Good suggestions! I will try them out for sure.

    Speed pulsing on BBS02

    Thanks to another poster it appears that this pulsing is inherent in the design of the controller. He suggested removing the speed limit and just adjusting power to give the assist needed to maintain the target speed with the desired effort level. This should eliminate the pulse and glide...

    Speed pulsing on BBS02

    I don't believe I have access to the cadence sensor as it is internal. The speed sensor you mention seems to be working fine - no dropouts in reported speed at any time. I will check though......

    Speed pulsing on BBS02

    I recently added a BBS02 to my old Giant 'Commuter' 26" bike. It was surprisingly easy and worked out really well. I use a 48V/17.5Ah battery. My objective was to have a bike I could ride with a 15 km/h effort and go 25 km/h for at least 80 km. My brief tests (still cold here in Ontario)...
