17.19 rbw detected :eek:

thats how fast i can catch them and im even faster now and have clips
I wouldn't want to go that fast over the flats - I can't get to the roofs and my folding bike would snap... but hill climbing is even better now that I've increased the cadence sensored BBS01B controller's amperage limit on my 20" wheeled Dahon Helios folding bike from 15A to 18A. It's an even stronger heavy bicycle trailer hill hauler now. I'm pedalling as hard as I can, built up speed after the 25kph cutoff before I got to this hill, average cadence is 126. Gets steeper. The only reason I slowed down to 21kph at the end, was after I'd geared down before stopping, to answer a phone call. For easy hill climbs, cadence sensored is the way forward.




Tempted to increase controller amperage limit to it's max of 20A - I could switch off the 2A(?) lights I've soldered to the battery for rare circumstances which require more power, without risking the 22A BMS.

I didn't know you had 10T on the rear. I've got 11T, I want 10T! Don't think I can on this bike, actually I don't need 10T.

30k sounds bloody good going, used like that. I didn't see any Bafang motors on Peter Performance Ball's videoed reconditioned shelf, no TSDZ2s either.

it wont cost a lot to fix it so he just running it in to the floor and peter could service them but are so easy not much point plus you could just send it to red dragon to get it sorted if you had to

I could go bigger on the front, a younger me would have done that immediately after it arrived lol. I don't reckon I need it - crumple zones of my bike and body aren't designed for high speed collisions with big metal boxes on wheels.

Cheers, good to know, but there are still loads of Bafang motor parts out there, so I'll probably attempt installing Thundering Balls Of Performance myself. And those balls will be extra greasy.

1800 right now, but I need to wait for my voucher at least 3 weeks.
You should be ok. Entire cycling industry is on the back foot currently, with even big companies gone to the wall and others in ultra sale mode, so helfrauds should still have it on special. Or if not, someone will.

Finally sorted even better then I have expected.
Got a Specialized Turbo Vado SL 5.0 - completely happy with it. Its a hardtail, looks like bike and 16kg weight.
Thanks everyone for advices and attention.
