EBikes and wheel building

[MelodyWheels]

Hi everyone,

First post in this section of the BNA.

I've been building and rebuilding eBike wheels for about 5 years. I'm not a eBike expert, but I an experienced wheel builder.
I recently wrote a blog post about eBike wheels from a wheel builders perspective

I've be interested if you had any throughs, comments, suggestions.

Hi Adrian, good thorough article. My first e-single speed was in 2010, and experienced most of the issues you've noted.
At the time I was learning with flame suit on from George in Bassendean who was helpful and interested to try something new, but also couldn't hold back his disgust at how wrong it all was.

I had read you built Aushiker's Mukluk build wheels.

For all the carbon love I only recently heard mention of carbon rim to nipple galvanic corrosion. I quickly put my head in the sand, didn't want to let any OCD in on my new-to-me Fat-MTB the previous owner fitted with these 65mm carbon rims.



I saw the e-fat mention at the end. I'm going to try one this summer, the rim/hub built by the supplier while he was winter sick and full of scotch, then it was freighted and with its weight the box looked like it had been used as a medicine ball for the Wallabies. Not expecting the earth from it, the on/off torque and the salt water corrosion should mean I'll pay you a visit sooner than for other wheels.

I'd love to see some pictures of this if you have any? Do you know if the nipples were alloy or brass? I have some great horror stories of carbon wheels that were ridden on the beach at the Cape to Cape, however it was the alloy nipples and steel spokes that were the culprit .

So true....

I bought a high end rear hub motor ebike, I like tubulars so I purchased two major tom 36h cyclo cross rims able to take tubulars.
Had it built by a bike shop, spokes started breaking after 600 km. I had the rear wheel built by another bike shop after an accident. Again the spokes started breaking after about 600km.

So I did some research on the net and decided to build the wheel myself.

First I took out the spokes and drilled the hole to match the high angle of the spoke, second I laced the spokes from different sides of the hub flange to offset the wheel for dishing, as the flange is very narrow. I then trued the wheel eliptically and centred in the frame. I then took great care to ensure even tension by plucking the spokes (which no bike shop appears to do with any wheels)

All good so far, so I will have to see if my modded spoke technique and even spoke tension makes a difference in the longer term.
