I cut the bracket off the sensor with a small metal hacksaw which works well. My pedal sensor (magnet ring) stays on and locks in place on the square crank shaft with the spiky split washer and C ring. For added security, I have now attached the extension arm onto the magnet ring which helps to keep it securely in place and makes it a little harder to steal. The extension arm is cable-tied onto the pedal arm.

@@geartechstuff3592 I never got the extension arm part - not sure they send those anymore, or maybe just not with my model 🤷🏽‍♂️ the sensor just doesn’t seem very secure to me, even with the C ring on it - I’ll play around with it and see what I can do. Thanks for the video and the feedback

The battery seems ok so far after 9 months. I mostly do short trips so the battery usually lasts ok. I did do a longer ride of 9 miles and it started to cut out intermittently which is about the halfway mark of the alleged range. I was on full power the whole time though with some hills and some periods of not pedalling. I wouldn't trust it to go the full 20 miles though. 250 watts is fine for my usage, more power would be good but I think 250W is the legal limit here in the UK.

Hi, the magnet ring has some removable spiky grips in the centre that grip onto the square shaft of the crank so that it rotates with the crank. So you can remove the arm if there is a gap of 2 to 4mm between the pedal arm and the bike frame. I believe the extension arm is for when there is no gap between the pedal arm and the bike frame. In that case, you have to remove the spiky grip halves and secure the ring by cable-tying the arm to the pedal arm and carefully aligning it to spin true around the crank. You can leave the arm on in any case for added certainty.

@@geartechstuff3592 Isee those fingers as a washer held in by pressure, and I guess everyone has a different way of install, just glad I see different installs, the arm piece is not to rotate Isay, it looks like it is

Hi Gledii, that’s a very interesting idea, I never tried that! I guess if you can get the bearing cup (with the two notches in it) off, without removing the central Allen key retaining bolt, the outer case of the Freehub might slide off giving access to all the inner small bearings! Let us know if you try it and if it worked! I did find that, that bearing cup was super tight and you have to undo it clockwise (ie the reverse of a normal bolt or nut)

The thing is that my frehub has cartridges instead of the free bearings. I ordered the 2 notches tool and will post it if works... Thanks

Hi Glen See my comment with a link about four comments down! It’s not an endorsement of their products or an affiliate link. Mine is still going strong and working well though! I got the extra long one for added height!

Consult the exploded view (ev) for the shimano hub in question. That shows how the parts go together, no guessing.

I believe my hub is the: Shimano Hyperglide C8 - Freehub. It’s probably obsolete by now though! There are so many different types with different drive sprockets.

Hello The Eames style chairs seem to have a different sized gas lift diameter than other brands: This is my understanding: Eames style = approx 38mm diameter. Other office chairs = approx 50mm diameter. I couldn't find anyone selling these in the UK so I went online and found this company: Domini Design They appear to be based in Hong Kong but I'm sure my gas strut was delivered from inside Europe, either Netherlands or Ireland (as there are contact phone numbers for both of these countries). Be aware that the delivery costs more than the product for delivery to the UK so I paid over £40 UK for product and delivery. (Delivery costs are probably even more if you are outside of the Uk or Europe). This is the link that should hopefully take you to the page I used: You have to select the length you require (i chose the maximum size of 230mm - just the black section length), choose the length that best suits your needs. dominidesign.com/gb/eames-gaslift-gaslift-high-black.html Please note that this is not an endorsement of their products, service or delivery and I am not an affiliate for this product. I cannot say if this is a genuine product or an after-market reproduction. All I can say is that the product seems to work well so far and it was delivered within 2 to 4 weeks if I remember correctly. Hope this helps.

@@geartechstuff3592 Thanks - I've been really struggling to find a gas lift of the correct size

The flat untextured surface side needs to be adjacent to the angular - contact bearing nut .

You hammered screwdrivers? Remind me never to lend you any tools!

And it's also worth noting that you can degrease and re-lubricate the freehub without disassembling it - just soak it in mineral oil or similar, keep taking it out and turning it, and you should wash most of the old oil and grit out, then re-lube along between the moving parts, repeatedly turning the mechanism again. ua-cam.com/video/iQ6XgztsfmU/v-deo.html

No way my cup is going to come out by poking it with a tiny screwdriver, the way it's shown here. Thanks for your comment; I was wondering what was wrong with me and/or my freehub.

I think I agree with you. I'm sure mine has Norfolk sand in it from a recent bikepacking trip. I'd be ok taking it off but I'm not sure about the servicing of it.

Grease is too thick thatll make it sticky wtf are you saying

@@simonooink940 yes wtf shimano cable grease (white) !!

I just removed my Shimano FH-M525A freehubs (two units) and I did not see any grease on the seal face or the body fixing bolt. Instead, what I saw seemed to be a heavy gear-type oil, but definitely not grease.

I use to use Parktool CL1 apply to freehub because I think it will lube the freehub. But i'm wrong, freehub can't free while riding. So i remove freehub and cleaning all part with WD-40. Then apply shimano premium grease (green) inside the freehub's body and a little on spring to prevent from rust but not apply at paw. It's work. I think chain oil will mix with dust and rust inside the freehub. So it cause the paw unable to move as it should be. But if you usually clean the freehub, chain oil may help lubricate.

I’m sorry Ali, I didn’t remove the spring or measure it as it was in good working order! I’m sure it’s bigger than 20mm though.
