The link for the tyres takes you to 700, I'm assuming it's the 26" equivalent?
Any hints on the throttle controller not working when adjusted round slightly?
those above don't have reflective band but otherwise just as good and a little cheaper too.
I usually buy a few at a time from Rose bikes to save on postage.
No, all I can think of is somehow the cable from the thumb throttle may be strained/pulled.
The throttle needs to be activated by pedaling for a second first. Once activated, it will remain active until the motor cuts out. You have to pedal a little again to re-activate it.
If you still think that moving the throttle stops it from working, move the grip, left brake lever and LCD a little to the left out of the way first before moving the throttle to the right.
You may find out what causes it.
