You can fly the bike back from Delhi or Mumbai, but it's likely to be expensive.
Story Leavesley stayed with us while he arranged flying his bike from Delhi to Istanbul last month and he had real trouble finding a carrier to take the bike. The Indian authorities are nervous about terrorist action and, as bikes are classed as dangerous goods, many of the airlines are refusing to take them at the moment. From memory, he ended up with a choice of BA, Lufthansa or Royal Jordanian and none of them were cheap (about £2/kg to Istanbul with BA). I think this is because there's a lot of trade between India and the UK, so airfreight space is sold at a premium.
Shipping the bike is considerably cheaper, but it takes a reasonable time and port charges in the UK can be hefty. Have a search on the shipping page - I think a couple of people have shipped back to Europe for as little as US$450.
If Chris' quote from Kathmandu proves genuine, it's probably the best way to get your bike back. There's just the small matter of fighting your way through the Maoist blockade to get to the airport....
Hope that helps,
no pipe, no slippers
