Greenedge CS2 problems

I bought a CS2/16 in early September, and so far it has been brilliant...
I have done around 450 miles on the bike up until now, usually around 30 miles a day. My journey is mostly along a gravel canal towpath.

I think there may be a couple of faults developing on the bike over the last few days.

There is a loudish rattling noise coming from the front of the bike, it sounds like it may be coming from the forks. It has been getting progressively more noticeable over the last few days. The noise pattern matches the bumps in the road, and sounds like hard plastic on metal. The fork suspension itself appears to be still working when you bear on it when the bike isn't moving, and I cant replicate that same sound. I have checked for other loose items on the bike but cant find anything that could be causing the noise. At first I thought it may be the mudguard, but I don't believe it is.


The second problem is something to do with the battery/motor. Riding with assist on (I have it on 5) it has started to feel like the power is kicking in and out when it shouldn't be. I know that once you hit a speed, you should expect it to cut out, and am used to that now, but it now seems to be cutting in and out incorrectly. This has only started happening the last few days.
For example, I could be riding along a level canal path, at a steady speed below 15mph, and the power drops, and the difference needed to maintain that speed is very noticeable, then it kicks back in again.

I ride the bike 4 days a week into work, 15 miles each way, and charge the battery when I get into work, and again when I get home, so its being charged twice a day.

Just wondering if anyone is familiar with this bike, and can suggest anything to look for.

Many thanks
Andy

Is the battery receptacle thing still tight on the frame?
Cutting out can be caused by lots of things. We need a bit more to make an intelligent guess. Does it cut out after a bump, only on a hill, or when you're on a flat smooth road.

Thanks for the reply.
Yes, the battery holder seems fine, I checked that first when the knocking noise started as I thought the battery was loose.

The power thing happens at any time really. I was going up a fairly gentle gradient this morning at a steady speed, and i felt the dragging when the motor stopped, then a few seconds later it kicks back in again. It happens on smooth tarmac too, I dont think its bump related, but Ill monitor it on my way home tonight and see if there is any clearer pattern I can put on it.

Thanks again
Andy

Look at your pedal sensor magnet disc. Is it running with an even 1mm gap to the sensor.

Will do...Ive been watching some youtube vids this morning and that came up as a possibility....
Out of interest, the bike is quite dirty this morning due to the state of the canal path/trail i use...can mud interfere with that sensor as I know it builds up around that crank area....

Yes. It depends how much gap the magnet disc has to be moved out of line.

Well, I had a look at the sensor and ring before i rode home from work...
The sensor ring was not running true against the sensor, at one point it was 1mm away, the other side about 7mm.

A couple of days ago, my chain came off at the crank, I never noticed at the time, it was dark, but i am guessing the chain has knocked the ring out of alignment.

Anyway, I have cleaned it all up, and repositioned the ring as best I can...its probably 2-3 mm away all round now, but still not totally true.

The ring is movable, and is only held in by friction...that doesnt seem right to me? Surely it will move again in time...or is it likely something broke when the chain came off..

Given it a quick test run...it feels a lot smoother than it did but not convinced its right...wont know until my next decent run, probably Monday now.

As for the rattling, it turns out its the battery in the housing...I'll have to find some foam or something to stick to the back of it to make it a tighter fit in the housing I guess.

I will be ringing the shop I got it from tomorrow as I have only had it a few months, but it will be nice to know Im telling them the right things.

Rather than bother the shop, it would probably be better to put a big velcro strap around the battery, which will help keep it steady during all the bumping.

The pedal sensor will work OK now. If it misbehaves again, you only need to push it back. If you want a permanent solution, cut the end off a handlebar grip to make a big rubber washer that goes between the pedal crank and the magnet disc. To put it on, you need to get thye crank off, for which you need a crank puller tool - about £3 on Ebay.

That's a good idea...I'll hunt down some Velcro from eBay.

I was more worried if something else was missing from the disc as I'm just surprised it's not supposed to be locked in place. I'll do the washer trick I think. Main thing is I know what I'm looking at if it happens again.

Thanks for all your help.

I had an issue with my greenedge cs2 where the two spring loaded pins that connect the battery terminals where heating up enough to melt the plastic housing and cause issues with stopping starting and randomly losing power. Easy to check pop the battery out and gently push the pins to see if the springs have any bounce to them . I had to get ebikes direct to replace the parts several times . This was one of the main reasons I upgraded to a better quality ebike .

If your bike is only a couple of months old, taking it back to have a fault looked at would hardly be considered as 'bothering' the shop. Isn't that the main reason for buying locally not from a faceless e-retailer?

The reason he shouldn't bother the shop is because there's nothing they can do to solve the problem that he can't do himself. It's a £700 bike. The battery will rattle if you ride on a canal path. Eventually, the fixings will come out of the frame without better support. It's only meant to be ridden on smooth tarmac. That's the difference between a £700 bike and Bigdaddyuk666's Haibike. You can buy four Greenedges for the same price, which IMHO is a better deal.

Why get a bike from a dealer then do second rate repairs yourself just weeks after buying the bike? I cannot see your point of view at all unless you are a dealer who doesn't want to offer any sort of after sales service. If so I'm glad you're not local to me. Bother was just such an odd word to use.

It wasn't the frame mounts it was the spring loaded terminals I had issues with .
And I know my haibike is expensive but you generally get what you pay for .

As mentioned the greenedge is OK on flat tarmac but is no good off road. And with the battery issues I had it was starting to cost me due to not commuting cause bike was faulty etc. Yes the greenedge is considerably cheaper than a haibike
But if you take in consideration of bus costs to work as mine would be average £28 a week . I got my haibike on 0% finance at £98 a month with no deposit so it worked out cheaper than the bus .
So was a no brainer.
The quality of the haibike is better
The batterylife is better and
It looks nicer IMHO .
But that's just me .

Well I am a dealer and I'm not near you so you have nothing to worry about.
Your a dealer? What you got?
Bet you live in one of the sides,, Woodside?
