New bike with weird front dropout - Need to fit front hub

[Electricmover]

You're better taking a picture and uploading to this website. There are two kinds of forks. Threaded and threadless, and you had you hand covering the end of the other fork in the video, but I think it's threadless. And within each category, you have 1" and 1-1/8" diameter stems, making four kinds of forks.

A further distinction is suspension forks vs hard forks, AS a general rule suspension forks are a poor choic for motors if they are made of alloy, which is brittle. You can get away with suspension forks if you have a smaller motor plus good fasteners, which include torque arms. Changing forks takes experience and a bunch of parts, Going from threaded to threadless means you have to buy a new step to hp;d the handlebars.

I think it would be simpler to grind off the welds on the first forks, and use good fasteners.. Makes it easier to change a flat tire, Your motor doesn;t look too big either,




.

Yeah could probably grind them off with an angle grinder or something?
Yeah motor is quite small. This is not going to have a very high top speed. Will shoot in 500 watts approximately. At the most 600 watts in a slope perhaps. What type of fasteners would you go for? Something similar to torque washers?

These torque washers are amazon. Same price from China, might as well get these. I;ve used this torque arm from ebikeling on amazon.

Commercial ebikes don't usually use the long torque arms, but their forks and frames are better suited for motors, They're flat and wide where the motors go in. By the way, in this picture, nothing wrong with putting the torque washers inside the frame, if they fit, It's always about space, They're going to work on either side, but it affects the disl braje spacing here,

Forks often have those round insets around the axle to accomodate those lawyer lip washers. When you install a motor, you have to fit a washer in those recessed areas so everything is clamped tight.
