Everyone is in the same boat it would seem
Having to now sit in for a bike collection for my Marin, which was nearly £50 with parcelforce (who seem to be the only folk interested in big boxes). I just can’t do it for this bikes value to me unfortunately.
Parcel force can do it to allow you to drop it off at your local post office,no need to wait in.
Box it up print off the labels and drop it off.
Used it for bikes all the time,saves waiting in for a day
I take mine to the local PO £16 last cheap bike I posted. Think you're covered up to £150. No need to wait in or pay that much. Last insured up to £500 16kg bike was £31 and change.
Impressive if you can do it, but how you get a full bike into their dimensions of 3m (length plus girth) .. girth on a bike box is approx (76+22) x 2 =196 which leaves you only 1m for length.. and that's back wheel on. your going to have to go wider to get two wheels side by side.
