Hi, an update... The bike shop came clean and admitted that they broke off the sensor and dongle when changing the chain.. in fact when they took the wheel off.. So they fixed back the sensor correctly - minus the dongle. The engine gives assistance up to 15mph on the speedo. I took the opportunity to replace the battery in the Badass and affixed to the sensor and back on the bike... But - no change. The speedo doesn't halve the speed - the Badass is not working. Would you agree it's the Badass? I'm messaging them too to see if there are any alternatives.. Cheers

Ta for your help so far. Haven't had a chance to look at it - waiting for the weekend. I'll report back.

Thanks for everything. Added pics - I have a Typ 3.3. You can see where they tried to glue it on...

Because it looks like it fell off - there is evidence of glue too.. It's a Badass dongle I'm told - I've looked at the badass web site and can't see anything that looks like my setup.. Does the badass replace the original sensor? What I have is wire coming from engine going to sensor which is positioned on the frame in the right place for the pass of the magnet. Or is the dongle something in the engine..? Used the bike to cycle to work and was definitely held back on a flat straight where the assistance normally kept coming - so I think it's the dongle..

No error codes btw..

Hi, ta for the tips. The sensor was knocked - mender fixed it back on with a cable tie that I hadn't noticed. He came clean.. Don't know the type of dongle - I've asked the guy I got the bike from - see what he says. I'll let you know how I get on. Thanks once again.

Hi I have a Bosch-Intuvia on a old Kalkhof Endeavour. All going great until the chain broke.. took it to the menders who installed a new chain and cassette - and now the speedo only shows zero when moving. There is assistance but it feels constrained.. The bike carries a dongle and I've had the constrained symptoms before when the wheel magnet rusted away (which is fine) - but not the zero speed. Mender guy denies all knowledge. Does anyone have any pointers? Cheers Andrew
