Has anyone had this problem? my Bosch battery that sits in the luggage rack keeps coming loose and disconnecting - leaving a 1 cm gap - when I go over bumps in the road. it’s an Axa lock I think as the same key locks the Axa lock on the rear wheel cant see what’s wrong with it as the key seems to turn the lock Mechanism ok and the battery fairly new Anyone else had the same issue or got ideas?

Yes - no problem freewheeling downhill. I just spoke to the guy who I bought it from (second hand dealer ) and he says it won’t be the bearings but instead the chain needing replacing? But it is making a grinding noise

I have a one year old bike with Bosch Active Line Plus drive. The drive sometimes seems to lock so that I can’t backpedal at all which is annoying at traffic lights etc when I want to reposition the pedals to get going again. Only way to move pedals is to move forwards. Any ideas what the issue might be?

Hello - I have two bikes (both 6 months old) . They are both now cutting out. Sometimes it’s just the speed number that disappears and the drive stops providing power. In this case the power returns to normal after 5 or 10 seconds. Other time the whole display (Intuvia) goes blank and I need to stop the bike take off the display, put it back on to get it going again. It seems both of these faults happen when I drove over bumps on both bikes! ANy suggestions?

And now an immediate follow up.... The motor is beautifully quiet but since I got the bike back last week the chain keeps jumping off the front chain set.... Any ideas what I should adjust.....or do I have to go back to the dealer?

Just to offer a follow up on the noise issue if anyone is interested.... So I took the bike to the dealer again. They simply said that motors are meant to be noisy. I guessed part of the problem was that I bought the bikes in Rotterdam so my local Bosch ebike dealer is not the shop that sold it to me and to make matters worse is in a different country! So I contacted Bosch direct through their webpage contact form and got an instant reply which after a few more emails led to Bosch contacting the local dealer and asking them to send the motor to Bosch. Two weeks later they sent a replacement motor. Now the motor is much quieter! They did not say what the issue was but I got it sorted! Good to know Bosch are helpful!

Yes - thank you - did that and there is no play at all. Just a noisy motor!

Can someone explain what “play in the cranks” is and how to spot it?

You would have thought so but as long as the diagnostics says it’s good then they say it’s working ok - which it is but just noisy. Maybe it’s possible that one bike has a more recent version of the performance line? The difference between the two noise levels has been obvious since day one...

No. Both motors pass the diagnostics test. Dealer says they don’t know what the problem is and can’t return to Bosch as it’s passes all diagnostics. Both motors perform fine. It’s just that whining noise is really annoying especially when out on a run in the country where peace & quiet are appealing

Thanks for the reply. Both motors are Performance Line. I did consider buying Active Plus but both are definitely Performance Line motors

Did you ever get to the bottom of the difference in noise? Check out my thread to see what’s happening to my wife’s bike compared to mine. https://www.pedelecs.co.uk/forum/threads/bosch-performance-line-noise.34207/

I purchased two new Gazelle bikes for me and my wife. Identical model both with Bosch Performance Line motors. My bike’s motor sounds like a very noisy milk float - whining away as you pedal. My wife’s motor is significantly quieter - almost silent. Can anyone advise why one engine is so much quieter than the other?
