Hi,
I have a woosh rio. This morning for some reason the speed shown on the LCD is a few mph lower than it should be. I've had the bike 11 months and commute daily, so I know what speeds I usually ride at on each particular section of the commute and on the downhills it was up to 10mph lower than usual (usually 29/30 mph on the steep downhills but was showing 20). No wind this morning, so I'm confident that it's not a headwind issue. The speeds were consistently a few miles lower all the way to work.
I've checked the wheel diameter setting and still showing 26".
At first I thought it might be a magnet that had moved or spun round but had a look and can't see one, so I'm guessing the sensor is in the hub?
Any ideas as to what the issue might be?
Thanks.

the speed sensor is made of 6 magnets inside the motor's lid. One of them may have detached.
Please contact support@wooshbikes.co.uk to get it sorted.

Just a thought, 30 Kph being around 19 Mph,
could it have gone from Kph to Mph?
Dave.
Thanks Dave,
I had a look and it's still in mph. Been advised to check the magnets, so will have a look at that and hopefully sort it.
Cheers,
Michael

Thanks for your email regarding the magnets. I'll email you and update the thread once I've checked out your suggestion.
Cheers,

It's quite common for those magnets to become unglued. If you can find it in there you can glue it back with epoxy. Many controllers have a stting for the number of magnets, so if one has gone you can change it from 6 to 5 to compensate. For peace of mind, I'd want to know where the magnet is because it can't fall out of the motor so must be inside somewhere like stuck to the next one.

Had a quick look tonight and sure enough, a couple of magnets have become unstuck.. A job for tomorrow with the epoxy. Thanks for the help, guys :)
