Well, I would think there is nothing to prevent you from riding up Ben Nevis.
I'm not a mountain biker, but I guess it might prove difficult to ride around on top, as it's mostly broken rock. The path should be rideable though. If for that reason you're discounting Ben Nevis, then Ben Macdui is your best bet.
In reply to arandall: Of the 4000'ers only Nevis, Macdui and Cairngorm are worth taking a bike on. I'm not counting Aonach Mor by the gondola!
Depending on ability and route it is possible to ride all the way to the summit of Cairngorm, there are a variety of descents, the best of which is probably round the northern corries and down the Macdui path.
Macdui is mostly rideable up if you go via Cairngorm but there is a few hundred metres of scree which is not rideable. The best descent is to the Hutchy hut.
Ben Nevis is largely a carry on the up, the best route being via the CIC hut as an out and back. The section from 1/2 way lochan to the CIC is mostly unrideable on the down but the rest is good if very busy above the lochan.
Highest elevation (in the UK) reached riding a bike.
1) The challenge must start on the public road system.
2) The challenge will deem to have ended upon the cyclist using a third point of contact to maintain balance. (ie. no dabs, bike ridden all the way).
Unless you can ride like Danny MacAskill, gates and fences may prove challenging.
I've been working on my own challenge, the 1000m summit to sea plummet. Deal is start at sea level (toes in water) then get up to at least 1000m (portage permitted)then turn round and ride back down (no portage) and put your toes back in the water.
I think it should be doable from Kinlochleven up to the end of the Mamores from the 1062 top between Binnein Mor and Sgorr Eilde Beag down one of the Enduro tracks into the back of KLL, not the landie track to the Mamore Lodge.

Last night I rode from Glen More to the summit of Cairngorm. I took the Allt Mor path at the bottom so there were a few short bits of pushing (maybe 100m in total). From the Ski Centre car park I rode up the landy track to the Ptarmigan and via Ciste Mhearad to the summit.
Nae dabs from car park to summit so if you took the road to the car park it would give c925m of height gain in a single push.
Is there anything bigger that's doable with nae dabs?
Summit of Beinn Fhada at 1032m to the sea at Morvich. Couple of K on the road to finish unfortunately. It is all rideable (Edit- on the down! it's mostly a carry up) but to do it without putting a foot down would be pretty tough.
