Also people running speed should be restricted to 15 mph to make complete sense.

I refilled my Kindernay XII with Red Line D4 automatic transmission fluid at 3000 miles oil change since Kindernay is out of business and there is no velvet oil for sale. It has the same color and even the same smell so I guess this is the same stuff, and it is cheap. I will will keep you...

Unfortunately all other e-bikes are crappier than some Chinese e-bikes.

Something happened with Cycle Monkey. People put a bunch of deposits on the products they sell and Cycle Monkey stopped responding a few months ago and their website is recently down. I hope I will get my money back for the Kindernay cage and oil I still have not received 3 months later.

That is KMC CL555 missing link on the picture he posted and it is not reusable. And you can see the locking tabs. Reusable missing links do not have locking tabs. He just was able to force the plates over the tabs, maybe those tabs do not work well on that 11 speed missing link, but this...

That's interesting. KMC claims those links with tabs are not reusable and I was not able to unlock such link with such tabs on my 1 speed chain with such tool because of the edge of the link plate hits that tab.

I do not know about rebuilding the original Yamaha battery with the original BMS but it looks like you can use any non OEM battery with hacking dongle as long as you can figure out how to connect the power leads. You also can reuse the original Yamaha case and connectors with new guts (cells...

That chain link on your picture is not removable with that tool and not reusable. See that tabs - those tabs lock the chain link plates and the only way to remove it is to brake the chain extracting the pin with chain braking tool.

That's one of the reason I switched to a Chinese frame e-bike with Bafang motor and build my own batteries. I have a Haibike with Yamaha system but the 500Wh external bettery it is equipped with costs more than $800, which is about the price of full suspension carbon fiber frame. I know the...

Ask dealers, they might have some old stock parts. Cycle Monkey ( https://cyclemonkey.com/kindernay ) is a Kindernay dealer in the USA. But do not place order on their website on anything before asking them and getting response if they have the items in stock and ready to ship. I ordered a...

You don't need dishing and all those fancy tools. Just flip the bike up side down, put the assembled wheel on and use a couple of zip-ties with a ruler, a tensioner and a cheap tention meter to align the rim and to set the spokes tension. Your bike frame and fork already have all the features...

Thank you for the info. It looks like Red Line ATF is the best among some most popular ATFs

It is legal to make whatever you want with your ebike. It might be illegal to ride some ebikes in some places.

I ordered a SWAP cage and some oil for my Kindernay gear hubs a few weeks ago from Cycle Monkey. I hope this will not affect my order. But it looks like they do not have the items in stock since they still have not sent me the purchased items. Also all these items on the Kindernay website are...

I recommend to use EBC brake pads with sintered compound (the orange one) - those last the longest period of time and do not loose grip in wet environment.

The issue is probably inside the gear actuator and it is fixable. Read this https://www.emtbforums.com/threads/dengfu-e22-frame-thread.26880/page-37#post-439758

Cars and theft are significantly bigger problems with e-bikes than speeding on e-bikes but nobody declares en emergency about those two issues.
