Agree. Imagine how less harm would be if we banned cars completely and just used acoustic bicycles! Approximately 3,700 people die in car accidents each day worldwide! Almost 20,000 people died in car accidents since this topic started! We need to do something, ban the cars and force everyone to...

Insurance companies are in business of making money. If they believe covering e-bikes relater liability won't make them money they will not cover it. There are multiple reasons they believe insuring e-bikes related liability will not make them money.

Sure, and that's fine. But there is no need to add more restrictions on e-bikes, especially if you believe you can win the legal battle.

You will be liable for caused harm regardless if you rode acoustic bicycle or 9000W electric bicycle.

The Problem Solvers Two-Pulley Chain Tensioner (remained from the Kindernay kit) does not fit because of the cog is too big (I purchased the smallest 3x3 cog with 24 teeth but it is still too big). I need to find a bigger chain tensioner or modify the one I have, or figure out the derailleur...

The rear brake caliper mount post interferes with the torque arm (on Dengfu e55 frame). I had similar issue with Kindernay VII and I ground off some material from the torque arm to make it fits. But the interference with 3x3 torque arm is bigger and would require removing too much material from...

The question The speed limits, licensing procedures and regulations for motor vehicles are already set, but 99% of people speeding anyway regardless of all those regulations and licensing. So the answer is no, high speed capable e-bikes should not be regulated any more than it is right now...

Ordered some SAPIM STRONG J BEND BLACK SINGLE BUTTED 14|13G OR 2.0|2.4MM SPOKES for this hub https://www.prowheelbuilder.com/sapim-strong-j-bend-black-single-butted-14-13g-or-2-0-2-4mm-spokes.html And some SAPIM POLYAX 14MM 14 GAUGE SILVER LOCKING BRASS NIPPLES...

The 3x3 parts have arrived! The parts look like very high quality product. The 3x3 hub has no free play between the case and the axles whatsoever (Kindernay gear hubs have some free play). Unfortunately there is no chain tensioner in the kit and no tubes for the cables so this stuff should be...

Here are the parts need to be replaced (one sun gear and 2 ring gears). These are steel gears pressed on or in the aluminum parts. The steel gears have knurled surface on the mating face crushing into the aluminum material to grip it firmly. Other gears have nearly zero wear and look like...

I have disassembled the gear hub completely. The last tricky part was to remove this plastic ring. You have to remove the planet gears and press a plastic tab down through the opening catching the plastic ring on the opposite side at the same time with a pick tool The rest can be...

I already see the sun gear is busted. Some teeth are sheared. Maybe Kindernay or whoever purchased their assets after their bancrubcy can sell those gears as spare parts? A good gear hub design should be with easy to replace gears and gears should be sold as consumables. Planet gears look good...

Alright, I figured it out. You need to attach the cog, rest it on two pieces of plywood, put an appropriate diameter socket on top of the shaft flange (I used 11/16" hex socket, it fits perfectly) and lightly tap it with a rubber mallet or you actually can just press it with bare hand (it is...

By the way all the custom plastic parts in this gearbox are 3D printed parts. For instance this black part looks like FDM 3D printed part, probably nylon This white part and other white plastic parts look like SLS 3D printed nylon

This is how far I was able to disassemble it and stuck. It looks like there is a plastic ring sitting deep in the bore needs to be extracted next to proceed with disassembly but I do not know how to extract it. It has some slots, maybe it needs a special tool to grab those slots, maybe rotate...

I might be able to fix it. I opened the case and I see nothing disastrous yet. Here is how to open the gear hub. Clamp the brake rotor to a table and twist the shell to expose the case tabs. You might need a grip tool but it might be possible to do with bare hands. Find some thick plywood...

My Kindernay VII is over. Placed order on 3x3 with Vapor Propulsion Labs. Where I can find the 32 spokes 12x148 mm through axle hub sizes to calculate the spokes length? I am also quite skeptical about the grip shifter with wire actuation. My frame requires quite sharp turns of the cables and...

Welp, My Kindernay VII is finally broken. I did 30 mph in light uphill on my Bafang m620 with 3000W Innotrace controller, everything was fine and then all of a sudden quite loud inconsistent clicking sound with resistance spots. I was thinking something happened with the Bafang m620. But after...

Here is how you can connect VESC Express to VESC for Bafang controller. Here is the parts list: 1) Some PHB 2.0mm crimping terminals (you need just one). Can be purchased as a part of a set here...

What is the maximum speed you can achieve with this setup? The rear pulley looks quite large.
