Bosch battery problem. Is me or the bike?

Hello everybody

As I said in some other posts I have a cube hybrid reaction pro which I couldn't use much but that I enjoy and really like.

When I bought the dealer explained me to take care when I put the battery on as other customer lost his battery while riding. He told me to turn the key and press quite strong to put in. As he told me that and afraid of losing it while riding I check after putting in everything pulling the battery to see if is hold.

Yesterday I was coming back home listening music with the headphones and had the feeling I was listening something from the bike, I stop the music and I was right. So I just decided to touch the battery while riding as I was in a big road and couldn't stop and the battery move. So after some meters I stopped and put in the battery again.

Today in the morning I was coming work and when I arrived I was going to use the key to take out the battery but I didn't need as was out again.

Is this because I really have to push strong or because I'm doing in a wrong way? Could be a problem with bike?

I know most of people will say that could be everything but I just would like to know if someone has the same issue as me.

Thanks

You fit the battery with the lock open, no force required. once in turn the key to lock and remove the key.

It sounds like your battery mount needs adjusting a little.

On the 2014 models it's better to have the key in the locked position, and listen for a "click " after firmly applying pressure. It does need a firm push.

Give it a bit of a pull or wiggle to make sure before riding the bike, just to be sure.

I have the opposite problem.. After a fast and bumpy downhill run.. and I mean fast and really bumpy with both wheels off the track at times, I find the battery to be stuck and considerable force is needed to remove it. On closer inspection the battery seems to have moved in the bottom cradle showing a 5mm gap between it and the bottom cradle..... Normally its a snug fit so dont know how it moves....

On the Active line, the battery fits real snug. You really have to push hard on new model and listen for the satisfying click noise to ensure it is locked in place.

 

The Active line can make 2 click noises when pushing on the battery, its the second one you are listening for... Push harder.

 

The mounts are adjustable if needs be.

 

But the Classic batteries can rattle a little so Bosch has advised tigheter tollerances on both the Active and Performance line.

For clarity on this can you expand on this clicking you mention? Are you suggesting that a battery is inserted into the holder with the lock locked?

Hi,

 

Yes you can insert with the key removed.

The first click comes from the battery engaging with the clamp, the second click comes from the lock itself snapping into position.

 

Its just one big click on the Classic+ system.

Perhaps you'd like to explain why the manual differs from your opinion on the correct way to fit the battery? page 33

In order for the battery pack to be inserted, the key A5 must

be inserted into the lock A6 and the lock must be unlocked.

Not surprising you dealers who insist on abusing the locking system on the Bosch batteries have problems.

This cut and paste from the instructions for the 'old' Bosch motor also says you must insert the key to insert the battery.

 

Nonsense.

 

I have two of these systems - both batteries click in without using the key.

 

In fact, if you pratted around with the key it would be harder to get the battery to click home.

 

...Inserting and Removing the Battery (see figures E�–F)

In order for the battery to be inserted, the key 17 must be inserted into the lock 18 and the lock must be unlocked...

Has anyone any advice on keeping mine in place? (2013 Classic) on really rough and bouncy terrain the bottom pops out slightly making it hard to remove from the cradle! I cant see how it might be adjusted...

Just to reiterate, the classic system works best as described in the above quote with the key being used to lock in after the battery is inserted, though this can vary depending on how the lock is set up in relation to battery position.

 

On the newer models, I've found it works well if you do indeed lock the sprung latch and feel / listen for the latch to take hold.

 

The reason I do this is because you cannot always tell if the battery is fully "latched" if using the key in the same way as the classic set up, and have found on occasion that in fact it hasn't fully locked in -fortunately, I always check the battery before moving the bike.

 

As I work in the eBike industry, I do this procedure several times a day, and have found no reason at all not to do so-No damage has ever occured from this, and I wasn't aware of any other dealers having battery problems either.

 

If I was damaging my stock, I would not do this.

 

Consider the "Yale" locks on front doors....They work in the same way, yet nobody ever turns the key when closing one, they just click it shut.

Gaffa tape.

My KTM required the key, my Haibike does not. Gen1 motor and battery.

 

Take the battery out, if the catch can be pushed by hand you do not need the key to fit the battery.

 

Despite any instructions, Bosch produced both types of catches.

The adjustment is made on the bottom mount, once the plastic bits are removed. Adjust the mount upwards so that the battery only just slots in with the lock open. If you can fit the battery with the lock locked the bottom mount is too low.

 

Martin gives a slightly better explanation in this thread where the bad practice of dealers and manufacturers has been touched on before,

It certainly dents any confidence I might of had for these dealers who can't understand how such a simple locking system works.

I can't comment on there being two different systems having only seen my bike. It seems highly unlikely to me though. Mine can be pushed up a bit, but not fully.

A Yale lock operates differently than this lock though. Perhaps you'd be so kind to actually see how far you can push the latch up whilst locked, then open the lock with the key, then come back and tell us all how much more the latch moves when you use the key.

I've just tried the latch on the Rose.

 

With the battery and key out, the latch can easily be pushed into the fully 'in' position - just like a Yale lock.

 

When released the latch springs back, again like Yale lock.

 

SRS (above) has the answer, Bosch must have made two types.

Did you try it with the key too Rob ?

Gaffa tape.

Yeh, Tried this and it works, but it dont look too good! LOL:)

Did you try it with the key too Rob ?

 

In the interests of research (and forum harmony).

 

Key in makes no difference, you can still push the latch in and out.

 

Obviously, turning the key retracts the latch, but both are spring loaded, so the key and latch return to the start point when the key is released.

That's not answering my question. My latch pushes in without the key. But when you unlock it with the key the latch moves about 5 mm further in.

 

If your latch moves the same regardless of if the key is used then there do appear to be two types of latch.

I like harmony, it goes hand in hand with so many things!!

I had a big problem .. I use mine every day for a short off road 4 mile post office run, all weathers winter and summer, snow rain hail mud and cow shit! Oooopps, am I allowed to say that? And the lock seized up! Took me ages to get it work so I could unlock the battery and clean it all up! Lesson learned there;) my latch is pretty poor

cow ****! Oooopps, am I allowed to say that?

 

Clearly not. I'm not so bothered about harmony, I just want the correct information, without any bull ****.

 

Oh and some kind of acknowledgement when one takes the time to answer a question, a like is good, as long as you actually find the answer useful. Hard to like answers when they're incorrect though.

My KTM catch could be pushed, perhaps 1 or 2mm and definitely required a key.

The haibike lock catch can be easily pushed completely back in its housing, it definitely does not require a key when fitting the battery.

 

Either way, once fitted and latched in the battery will be secure, assuming the lock is such that you do not have loads of battery end float.

Arstu, I am here to give advice. I dont get paid to sit on the forum, I choose to help others out of my own time.

 

It appears that different manufacturers have been using different mechanisms. In my experience I have seen both 'Abus' and 'Trelock' lock mechanicms on different bikes. Who knows maybe KTM use a different one all together.. Its clear that the older KTM's (Yours & Ians) do seem to use a different lock. But you cant relate this to every bike and infact the newer Active / Performance lines which use different mouldings all together.

 

Yes on my large range of Bosch eBikes (from varied manufacturers) the battery has always been able to be inserted without the use of the key.

 

Yours sounds like it does not, so you require the key to re insert, no biggie, just use the key.

 

Saying things like -

Not surprising you dealers who insist on abusing the locking system on the Bosch batteries have problems.

 

This is unfair... We would not look to abuse anything, we are here to help. In most situations its the other way round, users have abused the system and we have to clear up the mess.

 

Just to sum this thread up - All of mine can be re inserted without the use of the key. As many other have stated here. But some dont..

 

Lets keep the focus of the forum a nice place to be and continue to help, guide and assit others.

 

The original post of this thread has been answered, so lets leave it there

 

Happy eBiking
