Sonder Transmitter help changing tire

Loving my new bike but got a flat last night and there appears to be no way of getting back wheel of. There is no lever on the bolt and no way of getting the bolt out. Anyone able to help? Jackie O

Does it look like this?

I’ve got one of the proto frames and the rear skewer is a sort of through-bolt QR with a flip handle on the brake side and a knurled nut thing on the driveside – as above. I don’t know what the set-up is for the production bikes, but clearly it must come out – what does the end of the bolt look like? Is it hollow? There might be an allen keep slot hidden inside? Can you post a pic?

If it’s the same as my proto, it’s basically a long Allen bolt with a 6mm hex head on the disc side.

Thanks Brant, followed your advice and got it sorted. I need to remember to pack some fairy liquid to get the tire off. Its all a bit tricky these days! Love my new bike though….
