The King Meter on my Woosh has suddenly stopped indicating both speed and distance travelled. The sensor on the rear wheel is correctly aligned with the contact on the frame (I think, but what is the gap between sensor and frame?)

 

It happened after I turned the back light on for a ride home one night. After a few miles I noted the above faults which were not there prior to turning on the back light. The current time, battery level etc are all still working. All the settings were as they were and the battery is not indicating any dimness.

 

Has anyone had this problem or can offer any advice?

does the speed sensor have a LED on it?

if it does, then you can check if the LED blinks when the magnet passes in front of the sensor.

No. Only the one on the bottom bracket

you may need a new speed sensor, with LED. We can do sale or return.

Please email support@wooshbikes.co.uk, andy will look after you.

Don't have a Woosh, but must say great service and it would make me look at Woosh when i change or add a bike next year.

I got the same symptoms a couple of weeks after I fitted my Woosh kit.

I emailed Andy at Woosh asking for advice, got a reply within a few hours and a new speed sensor arrived in the post 24 hours later which fixed the problem.

I find them very nice folk to deal with. Helpful and efficient.

What was the gap between the sensor and the magnet when it failed? I'm clutching at straws here, but will email Andy at Woosh as suggested

around 3mm, Andy recommended as close as possible without touching.

email today, I'm sure you'll get a swift response.

Thanks. Strangely mine is quite a bit more,

I had similar problem today after changing battery in King-Meter. Nothing else was different on the bike BUT the speed display remained on zero. My mileage seemed to be stuck but I noticed that, after travelling about 14 miles, the mileage had increased by 1! About 3 times on the ride, after switching King-Meter off (and cycling without battery assistance) and the back on again, the speed display showed some strange number (I think it showed 33 mph at one stage) but there was no battery power. I then switched the King-Meter off and back on again and, hey presto, the battery was working again (but back to the speed being stuck on zero). Normally I'd say it might be something to do with the speed sensor on the rear wheel but the only I have changed is the battery in the King-Meter. Anyone have any ideas?

You should email support@wooshbikes.co.uk - Andy will help you diagnose the problem and sort it out.

Check the speed sensor Hall with a meter, power the bike up and find the speed sensor connector at the controller. Probe the back of the connector Gnd/Black and 5v/Red to confirm 5v is present, if not Hall is defective and speed sensor needs replacing. If 5v is present probe the Gnd/Black and the third colour/Signal wire also slowly rotate the wheel to see if the voltage changes form 5v to 0v, if not change the speed sensor.

Thanks for your advice. Not sure I have the technical ability (or equipment) to carry out those checks so, as a first step, I will try Andy at Woosh bikes.

I took Nealh's advice and contacted Andy at Woosh Bikes. After trying a few things that Andy suggested, his hunch was that it was a faulty speed sensor. I ordered a replacement from him (less than £20) and....Eureka!......it sorted the problem. All now working again. Andy (and Woosh bikes in general) is always so helpful.....one of many reasons to buy from them (No, I'm not on 10%!). Anyway, thought I'd post up the solution - in case anyone else has same problem.

The Hall sensor must have failed as that and the wiring is all there is too them plus the magnet for the signal to work.
