That looks just like how my mechanic set up my chain length, my bike is not with me, but going from memory it is same. Every bike will be a bit different due to differences in how the suspension is designed, but a good mechanic will know how to set up chain length for different bikes. I...

The bearing was noisy and still has some noise, but what got me wondering about it was one day I was cleaning up the chainline and removed the chain guide around the SES sprocket and spun the bearing with my finger. It felt like a sloppy dry bushing, so that got me wondering and after some...

I fixed my SES jockey pulley noise issue yesterday. My mechanic checked it out and confirmed the bearing was shot at 200 miles of riding. I am in SE Utah and the bearing was full of sand and felt very rough when spun in my hand after removal. Mechanic had a bearing in stock that pressed on...

That is a big difference! My bike is loaded in my suburban for a trip, but will check it later today. I wonder what else they might have done, maybe a good driveline cleaning and lube? My haibike sounds like your first video, maybe even louder. I wrote performancelinebearing a week back...

THe bike should be set up be the shop before they sell it. Manufacturers do the easy thing and install it long as the bike still works, but if they mess up and spec out bike with a short chain then it will not go into lowest gearing easy. for a 1X set up it is very simple to check, just put it...

Thanks for this info, I will check my chain length.

I bought a rocky mount solo rack for my prius, it is good for a 60 lb bike and also expandable for another lighter bike. It is very well made and much more affordable than the big name ones. https://www.amazon.com/gp/product/B076WTCZD5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 But I...

huh? There is a large blue "comment" box in upper left hand corner of page. Is it not working? I went for a long ride today and have not made my comment yet.

I have a similar noise I suspect is the shot bearing on the SES sprocket. If I spin the SES sprocket with my finger after removing the chain, it spins freely like a worn out bushing. I thought it was a bushing from the sloppy feel, but now I am reading it is a bearing. Performancelinebearing...

This may be covered elsewhere, but I thought I would post this link to the Dept of Interior website that is accepting comments until June 9th to change definition of Motorized Vehicles to exclude Class 1 Ebikes. The web page shows a total of 4700 comments as of yesterday, which does not seem...

Thanks Mike for the advice, you might be right on the idler gear being the source of the noise. The noise is gone for now, but it felt like a very loose and dry bushing when I was messing with it to get the chain re-aligned onto the narrow-wide teeth. I think I will see about replacing the...

Step #17 shows packing thick silicone grease around the axle/bearing interface. I suspect this is the thick grease I am getting on my shop rag mixed with dirt, sand and black chain gook. I have a tub of some expensive performance line ceramic grease that is super thick and I bet it would be a...

I totally agree, I picked this Jackery up for just a bit more than $300, for that price it made sense, now it seems to be over priced compared to just buying a battery, controller and inverter. I have a 17 ft RV trailer and I upgraded the battery to a nice 175 amp Trojan golf cart style battery...

Thanks Mike for your advice. I love the park videos and use them frequently for repairs and adjustments. I ordered the tool to remove the bosch lockring between the cranks and the seal so I can access the area where the axle goes into the motor for cleaning and inspection. I bet I put 2-3...
