I bought a Strida 5.0 a few weeks ago, and have been using it for my daily commute ever since. It works quite well, except for one thing : it makes an annoying “clicking” noise on every pedal turn when I’m climbing (or when I’m starting). Basically, when there is more pressure on the pedals.
It’s just a noise : I mean I don’t “feel” anything on the pedals themselves, it’s very smooth.
I have not been able to locate where it comes from precisely, as it’s hardly reproduceable statically. Except I’m pretty sure it’s not the saddle moving around under my weight (it makes a different noise).
Does/did any Strida owner experience the same thing ? If so, any idea on how it could be solved ?
If it is not the kevlar belt slipping (check the tension) then I know what is it.
At first the store (an official store) said that everything was fine (WTF?), and they said that after they took the bike for a full WEEK to check the noises.
So I pick up the bike, rode it and the noise came back. 10 minutes later I was turning to the store to have a nice conversation with the “expert” that told me that everything was fine. Guess what? when I came back to the store the “mechanic/expert” was missing so I complained again to someone else.
They ended changing the folding pedals (now I have another ones from Dahon) and the noise is gone.
On the other hand I keep hearing the brakes (disk friction?) if I’m close enough. In this case the same “experts” said that the bike was new and needed more miles (again: WTF is wrong with this people?).
I’ll bet Carlos is right and it is the pedals or maybe the crank arms. Have your dealer check that. As for Carlos’ disk problem, your pads may just need adjustment or shims. It is not an uncommon issue for mechanical disk brakes. If you are not mechanically inclined, have your dealer make the adjustment.
I Had the same problem and went bact to the dealer a couple of times to complain.He first said said it was because it was new and the noise will go away.It turns out there is something wrong with the rear bearing and Strida is aware of this and has recalled many of the recent bikes because of this problem.I was told that they will change it [The bearing]and will take it back over the weekend.I have only had the bike a couple of weeks[Strida 5.1] and it is a pity that that this occurred to an otherwise excellent product.
The Uk distributors said they had 1or 2 loose or noisey freewheels, but not many.
On the Strida5 this is at the back , like a regular bike so freewheel shouldn’t take as much load as my Strida3 freewheel, in the front.
I had exactly the same problem. Drove me crazy, because I only used my Strida few times and it used to be silent. At first I suspected the bearings of the bottom tube, which are also not okay, but this could not explain the sound.
I then checked every bolt I could find and found the source of the problem. The steel ring fixing the rear wheel had worked itself into the aluminium frame. This ring appears to have sharp edges and since aluminium frame is much softer than steel frame, it has no chance.
After removing the ring I did the following:
Carefully remove the burrs from the alu frame (for the largest part),
Used fine grade sand paper and a water stone to remove the sharp edge of the ring,
Then I mounted the ring with some copper grease.
Since then it works like a charm. No sound whatsoever and I am happy again.
Hope this helps you out as well.
I too hear a sequence of loud “click” sounds when bearing down on the pedals going up hill, or getting a fast start on level ground. sort of Whap, Whap, Whap as long as i am pressing hard on the pedals.
The problem comes only when I am really pushing on the pedal, and is easy to reproduce the problem.
I believe the cause is the freewheel is bending slightly when a lot of pressure is applied to the pedals, and so the alignment of the freewheel to the belt is off by a couple mm. That causes the belt to ride up on the the ‘guardrails’ on the freewheel that form the channel in which the belt fits while in contact with the freewheel teeth. So the pedal pressure bends the freewheel a bit, and the belt on the return side rides up on the guardrail, and then falls back into the channel with a loud click.
Can anybody confirm this diagnosis for the loud click, and suggest a solution?
The belt tension (top of belt should be tight enough so light hand pressure from above does not make it contact top tube) … adjust by slackening and rotating the eccentric BB, untill tighter … BUT not too tight which wears out everything faster.
Snubber has the right gap (small as possible without touching the back of the belt … ie about 0.25mm) … adjust by slackening lock nut then snubber bolt, to allow the bearing position to be adjusted, then re-tighten. I find this takes a few attempts as the position seem to move as the bolt and locknut are tightened. There is plenty of info on this forum … search ‘Snubber’
If its not the belt jumping … I’m not so sure what it could be, might need some more careful listening and diagnosing.
If you are right about the freewheel “bending” i.e. moving out of alignment, then you might check whether the bolt clamping the bottom tube to the seat tube is tight enough. I have this problem too at the moment (too much play between bottom tube and seat tube).
Hello,
I had a similar problem. I could hear an annoying sound every pedal turn.
After several trials I found that the bolt 464 was touching the rear wheel.
To be sure, I removed the Fender completely and the sound was gone.
After that I removed the washer 411 which increased the clearance between the rear wheel and the bolt.
Hope this may help.
Good ride,
Hi! I’m struggling to locate the clicking sound on my SX – looks like exactly the one you’ve fixed. Could you please explain in more detail – which steel ring do you mean? A washer between the axle and the frame? Or what??
The noises came back on the black Strida after riding ~ 700 km, this time I’ve skipped step1 and 2.
Applying of 1 or 2 cubic millimeters never seez at the cup spring edge killed the noise again with less effort
I have the same “clicking” noise issue.
I stated that it was louder when the temperature was above 20…25°C. I have read somewhere that the tension of the Kevlar belt increases with the temperature so either the noise comes from the freewheel, either it comes from the bolt and its cup spring which would be subject to higher forces at “high” temperatures.
I will try the grease method on the cup spring first.
I now have this clicking noise on my bike. I can’t make sense of the previous posts, so can anyone give me a step-by-step remedy in plain English for me, please? Thank you!
plain English might be a problem…
However, let’s give it a try:
Step 1:
Remove bolt 373, washer 364 and cup spring(s) 367 (363).
Step 2:
(I believe this step could be cancelled if the bike is relatively new.)
Step 3:
Meant is the sharp outer edge (diameter) at the inside of the cup spring 367 (363).
(The edge of the cup spring which had caused the burrs in the frame.)
One or two cup springs?
Actually, both of my 2010 Stridas do have one cup spring.
Thanks for this detailed explanation. I am happy to see that I don’t need to disassemble the complete rear wheel assembly (including brake caliper) to do this.
According to me there is a design error here: a cup spring/belleville washer should never be in contact with a soft surface like the aluminum frame, a (hard) metal washer should be installed in between.
