Beautiful build. Smart rear tire choice, it's going to out grip and climb anything bicycle.

Yeah, i ended up ditching the 3.5 trials tyre as it tipped the scale too much for me and went for a cheng shin 183a 3" mx tyre instead. The bike is now quite well balanced with the mx front tyre too. I recommend you try a front mx tyre... More weight yes, but more noticable grip and confidence and more balanced.

Hey
To bad all your pics are not visible anymore.

What headset did you use for the nyx?
I have a 1/8 fork and that pic of the headset on the nyx site makes me crazy.

So... Go to endless sphere and ask a NYX owner :p

Just waiting for a headset now for the rest of the build.

Next, to test the motor and controller and wire combos.

Hey Merlin, the headset is a cane creek, i cannot remember the exact size as NYX supplied it when i bought the frame as i was worried about not being able to purchase the correct size cups. It was expensive.... I remember that! To be honest, i am not sure exactly which part of the headset you mean. I will try and update some photos later today.

cane creek 40 zs series i believe.
i suspect it may not be easy to get another cheaper compatible type from memory.

I had to get them straight from Eloi at NYX in Canada. His english is not very good so keep the email short and simple (unless you write good french).

He will need a couple of measuremnts from you best taken with a vernier. He will send you a diagram of what to measure. The bushes themselves were about $30usd a pair, but shipping to the U.K was $40 :roll:

This is the email address he used to communicate.. info@nyxbikes.com

It maybe worth considering somewhere more local to machine one the same dimensions as the one you still have if it fits both bottom brackets and swingarms snuggly. It needs to be made out of 'Delrin' - this is a trade name, it comes other generic names.

interessting...another set of bushings. at this kind of "using" those delrin bushings should last years.
probably swingarm is also not in the right angle.
maybe i should post my "nyx experience" on the sphere. still pissed and doesnt want to "invest" time to this "experience"....

Mine were very tight when new, infact they stopped the rear suspension from working properly. Eventually they loosened and then there was play in the swingarms as they became unevenly worn. I agree Merlin, if the geomwtry of the frame and swingarm is correct the bushes should last years and wear eveningly.

The cromotor design would not leave enough clearance for both disc rotor and wire harness. The wire harness had to pass through the swingarm dropout rather than fit between the inside of swingarm and motor cover

At one point I did try a trials bike rear tyre which was 3.5” wide and could be used at very low pressure 6psi as it was a radial construction with very strong side walls. But the big downfall was weight, it weighed 5kg so I remov d it and went back to a cheap 3” mx tyre.
I limitmyspeed to about 45-50mph depending on weather. If I crank everything up on the adaptto controller and have a long enough stretch it will do 60on a full charge,but that’s too fast off road.
