February 9, 20179 yr Like many people already I found that the OE chain guard was clogging up with mud and causing problems, so I purchased the upgrade rings already on the market. I have only had the bike for 8 weeks and I've gone through 2 already (I swear they are made out of cheese) Then came the decision to change the chainring from 17T - 16T; which then would not allow me to tighten the upgrade locking ring to its required tightness. (picture attached to show the clearance issue and the OE lock ring) So I have taken matters into my own hands and turned down the OE locking ring on the lathe. I'm very happy with the modification, not only is it helping the mud and crud escape that area but it's certainly easier to torque up than the upgrade rings in my opinion.

[ATTACH]17693[/ATTACH] [ATTACH]17694[/ATTACH] Great idea if you have the skills andcequipent which ibdont unfortunately but have had my little silver one on and off a few times and am wondering how yours got broken....
February 12, 20179 yr Author The silver rings aren't broken, but in this weather I am taking them on/off every weekend during the clean process and to get the required torque the material is not strong enough in my opinion.
February 12, 20179 yr I see that like me you have an exposed pivot bearing which it would seem is peculiar to Scott bikes, so is it a Scott?
February 12, 20179 yr Author Yeah it's a Scott Egenius. I run a modified Scott espark chainstay protector over the bearing but it was not put back on after the clean down in this picture
February 12, 20179 yr Yeah it's a Scott Egenius. I run a modified Scott espark chainstay protector over the bearing but it was not put back on after the clean down in this picture I find this odd as its different to mine.. I have had 2 Scott E-Genius e-bikes from different sources and both came with the same front sprocket arrangement which is 17T Sprocket, o-ring on shaft and lock-nut /bash-ring, unlike yours which has the inner chain guard. The OM lock-nut has been swapped for the OM supplied silver one and all seems well. I noticed when last it was off for cleaning that the chain runs very close to the motor housing and in the lowest gear it almost touches.. Almost but not quite!! i remember thinking this is odd, but not a worry until In looking for a smaller cog I find this.. https://www.e-bikeshop.co.uk/bosch-drive-unit-sprocket Apart from the price this, like yours is very different to mine with its inner chain guard, and the advert states.. Please Note: This sprocket will not work with Scott E-Genius models as the inner plate has a 8mm offset. Please contact your dealer for these OEM specific parts. So mine looked like this.. Clearly no inner guard.. and previous e genius was the same..
February 12, 20179 yr So every 500 miles or so you are expected to pay out £99.00 for a new sprocket! https://www.e-bikeshop.co.uk/Scott-E-Genius-Bosch-Sprocket I'd stick the bike on Ebay tomorrow if I were you.

February 12, 20179 yr It certainly is weird and seemingly confusing that's for sure. SW will come up with an answer I am sure..
February 12, 20179 yr Author Just to confirm, yes both my 16T and 17T have the inner lip to protect against the motor casing, but I'm confused....who has said after every 500miles they need a new sprocket?
February 12, 20179 yr That is about all that I get out of any sprocket that I have ever used, and that is pushing it. I should have said that. I have quite a pile of old sprockets of varying makes and sizes. Connex are my preferred choice.
February 12, 20179 yr That is about all that I get out of any sprocket that I have ever used, and that is pushing it. I should have said that. Yes but I think you are a heavy user. I am at 700 miles and it's still OK. Just fitted second chain
February 12, 20179 yr Author Ah ok. Well the 17T had done 300m when I replaced it for the 16T and it was in good condition. It is worth pointing out that when I contacted Miranda they gave me a good discount ordering directly from them which came in a good £20 cheaper than ebike shop. (That's with the postage included)
February 12, 20179 yr Sadly so Gubbins. The conditions here are just so abrasive. This is an old set up after just such a mileage. Even the lower gears on the cassette have hooked up . New chain and old chain. Edited February 12, 20179 yr by EddiePJ
February 12, 20179 yr Author That wear is outrageous! Can't believe there is so much variation in soil etc on the same small island! I'll not moan about Yorkshire mud anymore.
February 12, 20179 yr Sadly a lot of the terrain here is like this when dry. And like this when wet. Look at the corrosion after leaving the bike for just a couple of hours. Get on the South Downs when wet, and things can be even worse, when the chalk and clay mix together. On the plus side of things, now that I have the private woodland to ride on, I can all but eliminate the above as no one else is around to spoil things by riding horses.
February 13, 20179 yr The sprocket issue is only relevant to e-genius plus bikes. It's the plus designation that is different
February 13, 20179 yr Author So if I had bought the 29er egenius I was looking at I could have used the cheaper sprockets? Damn! Although I think I'm having much more fun on the plus than I would have on the 29er.
February 13, 20179 yr So if I had bought the 29er egenius I was looking at I could have used the cheaper sprockets? Damn! Although I think I'm having much more fun on the plus than I would have on the 29er. What's the difference? Is it only wheel size.
February 13, 20179 yr Author Essentially yeah, but I had a genius 900 before the egenius 720, and the egenius definitely feels a lot more lively. I'm not sure if the 29er has boost hubs too?
February 13, 20179 yr Essentially yeah, but I had a genius 900 before the egenius 720, and the egenius definitely feels a lot more lively. I'm not sure if the 29er has boost hubs too? Boost hubs? Don't know what they are
February 13, 20179 yr Apparently they are stiffer. The word boost suggested an extra motor.. but no.. I chose the 29er because I am tall and prefer a bigger bike.
February 15, 20179 yr Author Yeah I did enjoy my old 29er but I got it more for the rolling momentum factor and keeping up with my friends who are a bit fitter than me. I found in tight technical stuff it wasn't as agile as I'd like though and now I have assistance obviously rolling momentum isn't the same issue it once was. I don't see why people mock wheel size preferences though - whatever gets people out riding their bikes is good with me
