High Sam! Long time no see! I had a wheel built with the same SA 3spd and brake. Never got around to using it. Still waiting for someone to be interested. I've read good things about it. You seem happy with it?samsavvas wrote:Hi Folks,
Haven't been to ES for a long while - not through lack of interest mind you - but just lack of time. However I think I need the community's help so here we are! I've just resurrected my old BBS01 250W/36V. It's been in storage for a year or so since last used, now fitted to an Kemper Filibus cargo bike.

The new rear wheel has a brand new Sturmey Archer 3 speed with drum brake. I've just been on a test ride and while the drive, gears, brakes etc all seem to work very well, I've noticed a new noise which I suspect I shouldn't be hearing and which wasn't there when the BBS unit was last used.
I've used a S/A 3 speed before in another bike and I'm aware that they make a very gentle high-frequency ticking noise when coasting due to their multiple freewheel pawls and I can certainly hear this with the new hub. However when I powered up the BBS today - both when I used the throttle and when I used the pedal-actuated drive - there was quite a loud lower frequency 'ticking'. Not a clunking or banging or anything I'd associate with a chipped or broken gear inside the BBS. Just a loud ticking sound that increased and decreased with speed and stopped when just coasting the bike under momentum.
I've eliminated the possibility of chain or any other drive train issues - it clearly seems to be coming from inside the BBS unit (which is otherwise working fine). Doses anyone have any experience with this noise and have any idea what might be causing it. Suggestion and insights much appreciated.
I'de definitely second the lubrication. I check mine and do some cleanup at the beginning of every season. So far we're going into season 4 with our 01's. Under rated little motors IMO.
I used aviation grade grease as someone suggested.
All the best!
