52 is incredible. Is that a 250w bbs01 on a roadbike? What level PAS? Mines the 350w on a 22kg mtb an im 14st. I only made 35 when it had a 15mph restriction 27 without. An thats a 17.4ah samsung cells.Usually have on max PAS tho.

I dont trust battery bar levels on the display . Ive noticed the first may last 15 miles before it goes out.Before you know it the remaining 4 have followed for only another ten. And soon its yet another embarassing kneecap popping slog home with all the pedal cyclists breezing past with smug...

Thats the exact one i bought £ 195 + £ 11 p+p. have put on my bbs conversion as the bracket of the shark case fits my other bike and this ones better for the bbs. It has a really solid metal bracket and location slots for fitting on the bottle mounts lower down.So avoids the central seat post...

Yeah neal thanks you mentioned that throttle before .When i sort my bbs out im going to get one

Yes the battery from Eclipse was the 17.4 ah samsung 29e cells. It was new 4 months ago.Ive done a 1000 miles on it and it does seem to have lost some range. Im afraid i find im often cycling 30miles.Running the battery til the bms shuts it off. I think thats not good for the battery ,but hard...

Got around to finishing the bike today. Bought a small panel mount volt meter for 36v use .Removed circuit board from original led battery display and cut top open for volt meter to clip in.Sealed with hot glue gun. Soldered wires to the ones for the original led. Didnt bother with...

Got bit excited there for a minute, to see all the new replies to my post....

Interesting, i was imagining the 15 mph cutoff at least returning 30+ mile .Thats something i noticed affected the bafangs range considerably.The controller has no specs or id on it unfortunately.

After moving an eclipse bikes battery from one bike to another and being suprised at the result.Im interested to hear others two peneth worth. I know there are so many factors, weight ,motor size,gearing ,15mph restricted or not. Etc. So basically. Fairly typical 22kg 26in bike, BBS01b 350w...

Hi d8veh.Pulling things apart and repairing myself is something i enjoy .But in this instance im hamstrung wanting to not void my warranty. Ive looked for anything like bad connections .Tried the disconnecting cables ect. Perhaps these symptoms are some hall sensor issue? Though i dont see why...

Hi Yes fordulike i have throttle completely disconnected. I tried disconnecting brake sensors after it died after 15 mile run yesterday. It did pop to life for a few seconds of on off on off then died again.

The motor and controller seem well sealed.My prob was rain getting in the throttle ,then rain in detached throttle cable connection. I dont think the controller is toast yet. These are the latest symptoms .After 3 days dead i decided to try disconnecting and reconnecting the display and...

My bbs01 motor itself has been heavily covered in water spray and mud and its been fine . I now know from my own experience and other peoples the problem was. Wet getting onto the connnections in the throttle .People suggest opening the casing and painting clear nail varnish on the wires where...

Thanks to d8veh and fordulike for always giving supportive comment on ebike issues .Will check phase an hall sensors with my multimeter during next few days. Its an awkward situation though. i have an infuriating need to find out how things work and be able to mend an maintain myself.Spent my...

Sorry to sound ignorent d8veh but what are these phase wires on the bbs01b controller .I saw 3 large wires and a connector with 4 thinner wires .So im assuming for this test ,the controller is completely disconnected from motor.The meter set to ohms.Then the black meter wire to the batt pos...

Is there any clear distinctive sign if its blown mosfets? No error code is being shown by the display . All the connectors and wires in the controller were clean,dry and secure.The red wheel sensor led is lit.The crank turns freely .Just no activation of the PAS.Before packing up this morning...

Yeah each one and both together,no diff.Display on but no PAS.Dead as a door nail.Im afraid during all this connecting disconecting the green plastic of the display cable connection is breaking up.I took the controller off but everythings perfect inside.No water or sign of something burnt out...

Your problem resolved.After another 24hrs drying,i thought mine had also.This morning the error code 04 had gone .With the throttle removed and the cable pins dry and capped. The PAS worked every time i spun the crank. Alas a mile into a test ride i stopped to open a gate and the PAS wouldnt go...

Thanks fordulike Sounds identical.I prob got water in coz i didnt seal it .But now ive sealed it still dead .Certainly didnt see smell any smoke, but is it likely as d8vh said on your post this could blow the mosfets? I assume yours was ok after a dry out.Any idea of a way of testing ? or just a...

Hi everyone Im back with more bbs01 issues and hoping for some more viewers advice. A little while back after only a months use the BBS01 PAS was cutting in and out.Disconnecting the throttle resolved this . Eclipse bikes sent a replacement throttle.Worked perfectly for a while , then...
