160mm dropout, is it normal?

[cwah]

Hello there,

I've a quick question. I'm going to potentially buy another bike so I need to know if I calculated the dropout correctly. I'm testing on my actual bike.

Measure from the left side

Measure from the right side

I'm not sure to have done the measures correctly, but it seems that I have 160mm dropout on my bike.

Is it normal? Is it the space required for disc brake? Not sure I measured it correctly.

Thanks guys

160mm is out of the ordinary.
Could be that the drop outs are currently spread.
Take the wheel off and measure again.
What type of bike? Brand?
Converted mnt. Bik, or Manu. EBike?
Let's see a pic of the whole bike :wink:

This is a mountain bike purchased from Conhismotor:

I'm trying to measure the dropout because I'm soon going to check another bike. I need to make sure the measurement is correct. Going to do it now. Will come back with few pictures.

In the first picture, it looks like the torque washer is on the wrong side of the dropout. It looks like they may have done that to make clearance for the disc brake rotor. If they did the same thing on the other side then that would explain the extra mms.

It looks like your ruler is about 10mm further to the left in the second picture. Look at where it crosses the spoke flanges on the hub.

I guess it's just too far away on those angles to really tell where the ruler is.

Wider than normal dropouts are not uncommon on bikes that are manufactured specificly for an ebike. 135mm is the usual width of a MTB rear end.

Rassy, It's a visual effect it looks like 10 mm to the left. On my eyes it looked straight, but anyway I just needed approximative measures. I was just surprised by the width of the dropout.

Dogman, thanks for your feedback. Make me reinsured.

Actually, I was meeting someone to potentially buy the Mezzo bike. I measured the rear dropout and it's 135mm. So the Bafang 36V500W can fit this 16" bike. I tried to ride it but I wasn't that convinced. The fold wasn't that convincing too, and it wasn't rolling that well once folded. Now I'm officially hesitating between the Dahon Jetstream and the Mezzo bike to electrify.
