If your Bosch CX motor (gen 3?) is making lots of noise, you can easily fix it by installing this kit. I've done it for my Riese & Mueller Charger GX and my wife's Mixte. Both bikes are almost six years old. After this replacement, motor noise is significantly reduced. Here's a link to a vid...

Here's a post about what I did to fix that noise the comes out of Bosch motors, worst-writer and worst-rider style. https://worstwriter.com/2022/01/28/charger-gx-new-battery-motor-maintenance/ Hope no one minds the link to my blog. Gotta sell it, baby. Just kidding. I got nothing to sell...

Great info JayVee! Just what I need. Yes, it's the rear wheel. Also includes traditional QR. Disks are 6 bolt. Cassette is 11 speed Shimano. Have tools to change cassette, although I've never done it before. More bike repair fun and learning ahead. Realign brake callipers no problem, can handle...

Approaching 12000km and over three years of use on my R&M Charger GX and while giving it a good clean the other day I noticed these hair-line cracks in the Alexrims. Obviously I need new wheels and am now facing the reality, after initial search of what/where/which wheels to buy... how the heck...

Would you believe... Alexrims spokes ripping through wheel?

Last pseudo-review of Charger-GX. http://worstwriter.com/2020/03/10/pseudo-review-charger-gx-10k

9000km, baby, and sprained shoulders. http://worstwriter.com/2019/09/28/pseudo-review-rm-charger-gx-9000km-sprained-shoulder-battery-degradation/

Bike is going in for scheduled inspection soon. Yes, curry Charger owner here and my über-e-bike is over two years old. After two rides this week, one mountain, one road, my battery was dead between 50-60km. I wouldn't say it's a warranty issue, although I'll be putting my bike in for...

Definitely not colder temps. Been very mild past few weeks. But there is some serious wind, like the ride yesterday.

Update: see attached pic. What's your experience with battery replacement? My 500wh Bosch battery is starting to show serious degradation after 9000km(+) on my R-M Charger GX. Where I once calculated my bike rides according to time, i.e. how many hours I need to get from A to B to A, I'm now...

Finally found where that obnoxious noise was coming from. http://worstwriter.com/2019/08/24/rm-charger-gx-inept-owner-or-incompetent-mechanics

Finally changed my tires. https://worstwriter.com/2019/08/10/r-m-charger-gx-urbanisation/

Initial review/thoughts on Super Moto-X replacing Rock Razor tires (tyres) on Charger GX. https://worstwriter.com/2019/08/10/r-m-charger-gx-urbanisation/

FYI - Received the super Moto-x tires this morning, even though I thought they wouldn't arrive till next week. Installed them right away. First impression after a short test ride in the rain? Yeah, baby. Should've done this a long time ago. Charger GX has been... urbanised. Review coming soon.

Changed from Rock Razor to Moto-X this morn. First ride proves I should have done this long ago.

I tested the rock-razor's with different pressures at first but found them to be unstable with low pressure on pavement. After that I never felt like bothering with air pressure. I've been running them ever since at around 3-3.5 bar for all surfaces--a bit hard at times but so is the hardtail of...

I'm leaning toward the Super Moto-X (62-584) you also recommended. Main reason is their wear rating--according to the dealer I'm buying them from. They are supposed to last longer than rock razor or g-one. I'm also unfamiliar with tubeless tires. Guess I'll have to read up on that. Thanks for...

Thanks for info. I've since measured a bit more and you're definitely right. And now I know the significance of tire width, which had me all confused. Would appreciate any other suggestion regarding moving from knob tires to more street/trekking tires? I ride 60/40 (street/off-road) and feel its...

I'm confused about tire sizes. Currently running 27.5x2.35 - 650B razor rock (knob) tires. I want to replace them with Super Moto-X tires. Will 27,5x2,80 (70-584) fit? Thanks for info. -T

Finally at 8000km, baby. Rant and ride on. https://worstwriter.com/2019/07/18/pseudo-review-rm-charger-gx-8k-km-the-killer-pug-saved-by-rack-time-e-bike-heaven-baby/
