    Article The new Performance CX Race, for ebike racing

    as far as I can see there are very few people who could exceed 80 during the limited motor assisted speed range of a pedelec except in a very low gear on a steep incline.... and then only for a short space of time/distance. The motors are designed to provide as natural as possible motor...

    Levo Gen 3 Broken chain stay on new S- works turbo levo

    The thing about carbon is that the initial damage could have been caused a long time previous to it failing because a knock can cause delamination which is not immediately visible......but that weakens the structure leading to failure at some future point. The chainstay is not under huge...

    ZEB pressure

    that pressure with resultant SAG suggests you have either not equalised the fork or it needs servicing ( lower leg service will do). Of course you may also not be setting sag correctly. I suggest you start by completely de-pressurising the fork and setting all adjustments like rebound, LSC and...

    YT Decoy Derestriction

    because the deristriction section alone is headed with the necessary warnings concerning the illegality of deristricting a pedelec and then using it anywhere there is public access.................and therefore protects the forum and its administrators from being accused of encouraging those...

    Rail (625Wh) 38t chain SRAM chain ring life span

    that rate of wear sounds a bout normal to me! Assuming you are not getting any slipped gears etc you have 2 choices now. Either keep running the existing chain until it gives problems at which time you wil probably need a new chain, cassette and chainwheel..............or change the chain now...

    Levo Gen 3 Broken chain stay on new S- works turbo levo

    what were the circustances? you may well have to argue your case because unfortunately the photos suggest the break was caused by an impact from below the chainstay.

    Unanswered Do I need to change tyre?

    The tyre is still fine or hardpack or loam but the DHR11 does not clear mud regardless of its age/condition. It does depend on the type of mud however! Loam turned to muddy puddles is OK..............mud with any clay and/or low levels of sand will clog the tyre...but then you know the...

    Recovering from an injury

    Only advice I would give is non medical! Don't let it dominate your life and worrying or worse getting depressed about it is not conducive to well being. So focus on adapting and planning. I know any injury tends to come back to niggle at you when you get old and yes broken bones often leads to...

    Article The new Performance CX Race, for ebike racing

    I doubt Bosch had to do much to implement the race mode. German engineering being typically Conservative and cautious the gen 4 was launched with 80nm and only one it proved reliable did they issue a software update to 85nm. I ride gen4 now and previously the Brose (2019 version with no...

    New E180 with the Bosch Race motor...

    Comparing the "Works" with the E180 RSX it looks like the Race version of the Bosch CX comes at something of a premium....£1000?? The Works has RS Zeb and Super Deluxe whereas the RSX has Fox Factory 38/X2.......some may say a bit of a downward step!! The rest is the same apart from the motor...

    Scott Genius etc motor cover removal - HOW ?

    take the motor guard off ( the plastic cover on the underneath of the motor) and the screws holding the non drive cover on will be exposed

    2022 Trek Rail 9.8 Bosch motor cuts out

    .........a foam pad will compress overtime........... a robust hard rubber should maintain its thickness . The foam pad has been around for years. My 2020 Whyte E180 (Bosch Gen 4) has one fitted as standard but it is not there to provide a tight fit. It is just to provide a softer interface...

    Answered 29 versus 27.5 in terms of power

    ...simply because they have less rolling resistance especially off road .....and being a bigger diameter carry more momentum.

    Levo Gen 3 No Battery Error

    its nothing to do with the battery and everything to do withthe rosenberger connection. Clean both with electrical contact cleaner and make sure the 2 spring loaded pins are free moving and that there is no debris in either. If that does not resolve the issue then the battery to motor cable may...

    Clicking noise from backwheel on new emtb.

    I believe that bike has MT400 Shimano hubs and the freehub is the Shimano type which is non serviceable (ie the freehub engagement system is inside the freehub body)........so you are stuck with whatever level of noise it makes I'm afraid. With an HG type freehub that has external pawls a loud...

    bosch gen 4 rattle, reply from bosch

    it rattles because the chain grabs the chainwheel as the rear triangle compresses and releases.........how much it does that depends on how the rear shock is set up plus the kinematics of the rear end. I get very little rattle on E180 RS. There is little or no rattle on my wife's Cube Gen 4...

    bosch gen 4 rattle, reply from bosch

    that could be cable rattle rather than motor. The models that had the battery electrical connector at the bottom have cables loose in the downtube unless you pull them tight through the grommets. The latest models with the rail mounted battery has less cable noise because they are all clipped...
