February 15, 20179 yr Re alumi pro with raised sprocket Is the front sprocket " 16t " specific to Haibike or will a generic bosch fit anybody know of a source of resonable priced ones in the UK. also need a replacement raised sprocket soon
February 15, 20179 yr Bosch is 15, 18 or 20. There's plenty of choice of suppliers for 16t, but it does need a specific lock ring tool. Sent from my E6853 using Tapatalk
February 15, 20179 yr Author Not removed it yet but the sprocket seems to have the haibke logo'd guide attached to it. ? Looks like a general purpose c spanner will fit the lockring. If not a Haibike specific will cost lots
February 15, 20179 yr Haibike does have lots of custom OEM parts, but you will need the specific removal tool for the Bosch lock ring. Sent from my E6853 using Tapatalk
February 16, 20179 yr Author Well if the tool is bosch it will be less expensive than Haibike specific. main question is is the sprocket specific
February 16, 20179 yr I've not had one in to be absolute, but the drive system is bosch. www.e-bikeshop.co.uk stock a sprocket to match, give them a call. Sent from my E6853 using Tapatalk
February 16, 20179 yr I bought one from e-bike shop, but they will only sell if you bought a bike from them. I think park tools do one , but more expensive than Haibike. Another option is go to the bikespeed rs website and they do one there. I have the original 16t, and since bought the 18t and 20t. I prefer the Haibike brand, as the cheaper connex ones were too close to the casing and damaged it.
February 16, 20179 yr The front ring is one of the few reasonably priced spares for the Bosch motor. Original ones can be had for under £15, pattern ones for less than a tenner. The lock ring is a left hand thread, I undid mine by tapping it with a blunt screwdriver so there's no need for the tool. Bike Discount is a reliable supplier for the rings, although there are others. https://www.bike-discount.de/en/shop/chain-rings-17868?currency=3&delivery_country=190
February 16, 20179 yr Author I had already Checked out e bike and found the same thing but £85 and only supply if you buy the bike from them. What is going on here?I had noticed the retaining ring was LHT .says on! ta
February 16, 20179 yr Martin at e-bikeshop does have an, er, unusual business model. I've never bought a bike from him, but he did supply me with a spare Bosch battery - at a small discount - a few years ago. This means I am 'in the club' which used to be more of a benefit than it is now. At one time, he was one of very few suppliers who had stock of Bosch spares. Increasingly, Bosch bits are now available elsewhere and usually at lower prices.
February 16, 20179 yr Think you are comparing different things. There are the ones machined out of one piece of metal with the bash rings incorporated & made out of Stainless Steel for £70 - £80. Then there are the sprockets alone and not Stainless for £10 - £15.
February 16, 20179 yr The cheaper ring will potentially damage your casing as it did with mine as sit's too close to case. i opted back to the expensive haibike ones and no issues.
February 16, 20179 yr Haibike do have lots of their own parts, I wasn't aware of the unusual 'club'! I would take the advice of others, otherwise you could end up spending a pound to save a penny as my dad used to say. Sent from my E6853 using Tapatalk
February 16, 20179 yr this is off set enough to work but limited to 17-18t http://www.pro-cycling-golla.de/Kettenblaetter/18_Zaehne_gekroepft_fuer_Chainglider_artikel54dc85a67f6b3.html tho if you want a 16t just buy a 14t and use it as a spacer on the inside
February 16, 20179 yr Hey soundwave, How did you get on with the big ring and badass dongle, speed wise. I've just taken the haibike 18t chainring off, and replaced with haibike 20t chaining. Now i find i will need to replace chain as derailleur is stretched. Even the haibike chainset leaves very little clearance (1-2mm) between chain and motor case. I think this is a slight design defect, as you can't afford to get any crud in there it will destroy case. Maybe, i should buy a spacer, but shouldn't need too as these chainrings are designed for bike grrrr. Waiting for bikespeed rs dongle, so i will see if the whole thing is worth it, or i'll end up back to 18t and existing dongle.
February 16, 20179 yr not had chance to get a chain yet as the jcp are being dickheads trying to sanction me for not seeking work??? and not signing a 3rd party contract under threat of a sanction doubt? it is the ses wheel that is the problem as it pushes the connex sprocket to close to the motor case as if it was not there on say a cube bike then clearance would not be a problem imo.
February 16, 20179 yr Sorry to hear that. not sure i can do much about the ses wheel. I removed guard but still get chain noise grrrrr. Seem to have to constantly lube whole chainset to get it to run well, Edited February 17, 20179 yr by Steve A
February 16, 20179 yr bearing might be shot or on its way out do you remove it and clean it inside and then re lube it? if you remove it and put ur finger in the middle and can feel it wobble then its toast. mine got so loud it drove me crackers tbh.
February 16, 20179 yr It's fine, along with crank/motor bearings. When well lubed / clean all ok, but i don't have time to do it after every ride. I get bike serviced every 6 months, full strip down. I usually clean bike once a week / fortnight. Never mind.
February 16, 20179 yr how many miles have you done? it is easy to remove it. https://www.adrenalinatv.co.uk/shop/components/xduro-performance-emtb-ebike-pedelec/haibike-xduro-ses-bearing/
February 16, 20179 yr it needs replacing then you will see what i mean when you pop it out n spin it it should be rock solid movement wise and not wobble what make the sound it will only get worse tbh as there cheap bearings in the first place.
February 17, 20179 yr Author Think you are comparing different things. There are the ones machined out of one piece of metal with the bash rings incorporated & made out of Stainless Steel for £70 - £80. Then there are the sprockets alone and not Stainless for £10 - £15. How can A single sprocket stainless Steel or otherwise cost £85 and the raised sprocke £45 e bike ! What planet are they on.? Think I need to remove the sprocket and investigate. maybe make up a bash ring and spot weld it on

February 17, 20179 yr Regarding price, it' supply and demand I'm afraid. As with bearings, I've had standard bearing in my old Cannondale scalpel which didn't last long so went for ceramic (4 times the price) and they lasted no longer and felt no smoother. I'll stick to standard bearings in future
