Replaced the tube in the front wheel of the InBred (it appeared to have a very slow puncture), turned the tyre around (easier said than done as it is a 700C Big Apple), cleaned the contacts on the dynamo and tightened loose bearings on the rear wheel.
Now just waiting for a delivery of a new rear wheel from MacB, then I'll swap over the cassette, disc and tyre.tube, hopefully ready for the ride tonight.
